The Uponor MLCP system
4
Basis for your professional
installation
The complete system from
one source
Tested Quality
Permanently watertight, together
with a long service life, are the most
important requirements that are
demanded today from a reliable and
high-quality installation. Uponor as
a leading manufacturer of plastic
pipes for house construction and
municipal technology fulfils these
requirements without reservation
with its Uponor MLCP system. With
this system we offer you the security that is so important for your
installation.
Whether it is tap water or radiator
connection – the Uponor MLCP
system is the perfect solution. The
comprehensive program permits the
complete installation from the
house connection line to the consumer. The installation is simple and
economical: The core of the system,
i.e. the Uponor Unipipe MLC pipe
and the relevant fittings, are manufactured in house and therefore
perfectly coordinated. Through the
inherent stability of the pipe and
the low linear expansion, only a few
fixation points are necessary – the
practical advantage for a safe and
fast installation. The Uponor MLCP
system is rounded off by a well
thought out Tool program: from
pipe cutting tool over bevelling tool
up to pressing tools.
With the Uponor MLCP system you
install tested and certified quality.
Thus you observe all required
building regulations, including fire
protection, sound protection and
thermal insulation regulations.
The system technology is also here
particularly long-lived and safe,
certified by numerous tests and
licences.

PE-RT Adhesive
Adhesive

Longitudinal safety welded
aluminium pipe
5 layers – built for the future
With our 5 layer composite pipe we
developed a product with
a future, which combines the benefits of both metal and plastic pipes.
Product benefits are obtained that
cannot be surpassed: The inner aluminium pipe is absolutely safe
against oxygen penetration. It compensates for the snap-back forces
and the linear expansion caused by
temperature changes. The basis of
the system is simple, safe and fast
pipe installation: simply bend by
hand, cut to length, bevelling, join
together, press – done!
The Uponor Unipipe MLC pipe consists of a longitudinal safety welded
aluminium pipe, to which an inner
and outer layer of high temperature
resistant polyethylene is applied (in
accordance with DIN 16833). All layers are permanently bounded
together by means of an intermediate adhesive layer. A special welding
technique guarantees a maximum of
safety. The thickness of the aluminium selected for the Uponor Unipipe
MLC pipe is exactly adapted to the
compressive strength requirements
as well as the bending capability.
Benefits

The Uponor Unipipe
MLC pipe has a
comparatively low
linear expansion due
to the plastic film‘s
firm bond to the
aluminium
The Uponor Unipipe MLC pipe for
tap water installation and radiator
connection can also be ordered preinsulated. You have an assortment
available in sizes from 16-25 mm
that fulfils all insulation requirements of DIN 1988-2 and the German Energy Saving Directive
(EnEV). The pre-insulated pipes
save installation time because the
time intensive insulation of the
mounted pipes and the resulting
gluing of joints are much reduced.
5
The resilience of the multi-layer
composite pipe is checked regularly
by tensile testing. Along with the
continuous laboratory testing of the
pipe, each Uponor Unipipe MLC
pipe is checked during production
for accuracy of size and water tightness.

Resistance of temperature:
Tap water: The maximum permanent operating temperature exists between 0°C and 70°C at a maximum
permanent operating pressure of 10 bars*. The short-term malfunction temperature is 95°C of a maximum of
100 hours in the operating lifetime.
Heating: The maximum permanent operating temperature is 80°C at a maximum permanent operating
pressure of 10 bars*. The short-term malfunction temperature is 95°C of a maximum of 150 hours in the
operating time per year.
* In some special products the permanent operating pressure is lower than 10 bars. Please have a look on the pipe marking.
In case of exceeding the maximum permanent operating temperatures e.g. in solar systems or district heating systems, the Uponor MLCP system can’t be
connected directly to this kind of systems. It has to be ensured that in every situation the maximum limits of use of the Uponor MLCP system are not
exceeded. In case of other use of the Uponor MLCP system Uponor has to be consulted.

Fast, simple, safe: The connection technology for
Uponor Unipipe MLC pipes
Extensive program from a
single source
Uponor shows its strength in the
development and manufacturing of
a fitting concept precisely coordinated to the pipe being used. The
pipe fitting program with its couplings, elbows, T-pieces and large
number of practical system components satisfies your every need:
Pressed or compression – both
methods can be used and ensure
durable watertight connections.
The flexibility of the Uponor
Unipipe MLC pipes can often reduce
the number of elbows needed
for the installation. This substantially lowers material costs as well
as reducing installation time.
Further benefits are shorter fitted
length and an increased installation
safety.
Even with complicated applications
you find the right connection in
Uponor‘s extensive fitting program
– whether press or compression.
Uponor MLC press fittings
Connections can be made within
seconds with the patented Uponor
press system. Complicated connection techniques such as a welding
or soldering are not necessary.
The connection technique produces
permanent watertight press and
compression connections, as is confirmed by the SKZ test reports and
DVGW certificates.

The first colour coding system in plumbing – fast, exact and
secure installation
Fast and secure installation
Practical experience
implemented in installation
Colour coded stop rings on the
well-known and quick to install
metal press fittings mark Uponor’s
latest fitting generation. Each
dimension from 14 to 32 mm has its
own colour – ensuring simplicity
onsite, in warehouse and wholesale.
The colour code system makes
installation a mere child’s play and
reliably prevents any kind of mixup. The foundation of the system
continues to be the proved and
tested Uponor metal press fitting in the latest generation now with
colour coding.
The new coloured stop rings offer a
safe stop for the pressing jaws. During the pressing procedure they
automatically fall off and thus mark
the pressed connection; nonpressed connections catch the eye
even in a few meters distance when
doing visual controls.

4. Insulating
A continuous pipe insulation like
Tubolit can be pushed effortlessly
over the unobstructed connection.
If a connection has not been
pressed yet, it catches the eye twice
during the hydraulic pressure test.
The coloured stop rings are still
there, and additionally the fitting is
designed to leak water during the
water pressure test. Now simply
press and the connection is sealed
permanently.

Robust, solid, reliable - the Metall press fitting with
outstanding properties
The new Metall press fitting generation from Uponor is the result of
continuous further development
and optimization, based on both
theoretical considerations and
practical experience.
Thanks to the new stop ring, the
Metall press fitting from Uponor is
now even more user-friendly.
On the one hand it ensures that the
pressing jaw acts at the correct
position during pressing, while on
the other hand it fixes the stainless
steel pressing sleeve to the fitting
body. So nothing can get lost, and
both the O-rings on the supporting
sleeves and the supporting sleeves
themselves are protected from
damage and soiling. The proven
inspection windows in the pressing
sleeve, which permit visual checks
of the penetration depth, also
contribute to maximally secure
processing.
Benefits
Use of high quality materials
Pressing sleeves are fixed to
the basic body
Stop ring for optimum
pressing jaw action
Inspection window for checking the pipe penetration

Safe and easy to install – Uponor MLC composite press
fittings with new features
The classic with improved properties. The next generation of Uponor
composite fittings for drinking
water installations and for the
connection of radiators, with sizes
from 16 - 32 mm, is available right
now. The familiar ease of assembly,
and the test safety offered by the
"not pressed, not sealed" feature,
are valued properties of Uponor
Plus on the building site. The visual
characteristic that identifies the
new generation is the white plastic
stopper-ring on the preassembled,
stainless steel sleeve.

The new, modular Uponor MLC fitting system for distributor pipes
and rising mains: flexible planning, reliable procurement, easy assembly
Faster planning with only
27 components
Flexible for planning
changes
Conventional 63-110 mm installation systems need up to 300 different components. The Uponor
MLC fitting system for distributor
pipes and risers mains needs just
27 components - a significant aid
to planning. In spite of the easily
managed number of components,
the system copes with practically
any imaginable task, and opens up
room for creative solutions.
When unexpected problems that
call for modifications to the plans
are met on the building site, the
fitting-and-lock principle of the
connecting technology allows
you to react flexibly. Connections
can be unlocked, released and
put back together again until
pressure test is done.
Benefits
Only 27 system components allow for hundreds
of variations.
New connection method, consisting of a basic
body and matching adapter inserts of tin plated.
Innovative push-in connection between basic
body and adapter.
Greater flexibility and lower logistics costs through
the minimum number of system components.
Optimum availability together with low needs for
warehouse space and for investment.
Fast assembly through pressing at the Workbench and pushing together on site without
tools.
Use of the familiar UP 75 pressing tool now up to
dimensions of 110 mm
Simple correction options when plans are
modified during installation
nent available at all times. Fewer
components also implies a lower
required investment, less administration, and a smaller space
required in the warehouse.
In addition, there are no rarely
needed special components - if a
component is left over at the
end of a project, it can easily
be used for the next project .
Building delays caused by
long delivery times, such
as are only too common
with special fittings,
therefore become a
thing of the past.

Uponor compression fitting system for multilayer
composite pipes
Uponor again presents an absolute
novelty: being the first provider of a
compression fitting assortment for
multilayer composite pipes with a
reliable test safety!
1. First cut the Uponor MLC pipe in
length
Take advantage of this unique innovation!
Concise product line – high
functionality
We have concentrated our compression fitting range and made it more
user-friendly, at the same time
keeping its high functionality in
mind! For example now all 1 inch
formed items and compression
adapters have been changed to
selected ¾ inch eurocone items.
This means for you: less storing and
no hazard to mix-up!
The new compression fitting with
eurocone replaces many parts of
the previous Uponor compression
adapters and has been supplemented with a plastic insert made of
PPSU which is in contact with the
medium water. That will substantially decrease metallic influences.
2. Mark the plug-in depth on the
pipe via assembly aid (enclosed
in all fitting boxes)
3. Insert the pipe in the new
Uponor compression fitting
(the inner part has already been
firmly connected factory-made!)
4. Tighten to the stop by using
a wrench. For ½ and ¾ inch
connections until the torque noticeably increases and the mark
becomes visible
Easy installation
Best-of-all: As the torque has been
reduced by approx. 50%, processing
has become considerably easier and
faster. A torque wrench is no longer
required, simply use a wrench until
the mark becomes visible. Assembly
times are therefore considerably
reduced.
5. Done

Equipotential bonding
DIN IEC 60364 ff. requires equipotential bonding between all types
of protective conductors and the
“conductive” water, waste water
and heating pipes. Since an Uponor
Unipipe MLC pipe is a non-conductive pipe it cannot be used for
equipotential bonding and is not to
be grounded.
Equipotential bonding is affected
according to the VDE guideline
from the parts that are to be
earthed directly to the equipotential
bus bar at the point provided in the
plan. The installer or construction
supervisor has to point out to the
client or their agent that a certified
electrician must check whether or
not the Uponor installation impairs
the existing electrical protection
and grounding measures (VOB part
C, General technical specifications
for building works ATV).
Mixed installations
For tap water installations with two
or more metal pipe systems, as seen
from the flow direction, first the
base metal and then the high-grade
material must be used, i.e. first the
galvanized steel pipe then the copper pipe.
Since the beginning of 1997 the
white Uponor Unipipe MLC pipe (PERT/AL/PE-RT) has been delivered
for all applications (tap water, heating and radiant heating installation).
The Uponor MLCP system can be
combined with metal and plastic
pipe systems. As opposed to mixed
installations using different metals,
with the Uponor system it is not
necessary to adhere to a tap water
flow direction.
If older Uponor Unipipe MLC pipes
are to be extended or repaired, the
Uponor MLC press repair coupling
offers the possibility of changing to
the current Uponor Unipipe MLC
pipe. The repair coupling is available
in the dimensions 25, 32 and 40. The
inner insert part extended on one side
of the coupling also simplifies joining
of the pipe ends to lack of space.
Repair or renovation work
In the past different variations of
the Uponor Unipipe MLC pipe were
delivered.

Outer corrosion protection of
Uponor fittings
Because of the external corrosion
protection there are no restrictions
for mixed installation with other
installation systems. The generally
accepted rules of technology are to
be complied with.
In view of the surface corrosion protection, Uponor MLC fittings can be
installed directly in concrete, screed
or under plaster.
However, there are some circumstances where protection from
metallic connections or metallic
components that come into direct
contact with building materials
is required, these are the combination of:
permanent or long-lasting moisture penetration and
a pH value greater than 12.5.
In this situation we recommend a
suitable covering for the Uponor
MLC fittings such as insulating tape
or shrink sleeve. Independent of the
corrosion protection of the mouldings, all legal requirements and relevant standards for the respective
application, particularly from the
stand-point of thermal insulation
and sound decoupling, must be
adhered to.
Before applying the insulation the
prescribed pressure test is to be run.
Threaded connection handling
instructions
The thread sealants must have been
tested and approved for the respective application. The sealants must
be used according to their manufacturer‘s instructions. Uponor MLC
press fittings may only be coupled
with standard screw threads (DIN
EN 10226).
The threaded connection must be
made before pressing so that no
stress is placed on the press fitting
connection. The threaded connections must be made properly in
accordance with the generally
accepted rules of technology. No
undo force may be used when
working with brass components.
Excessive thread sealant (e.g.
excessive hemp packing) at the
threaded connections must be
avoided.
The following points must be
observed when making threaded
connections:
Excessive tightening of the
threaded connection can result
in damage to the material; suitable tools must be used.
The installation tools may not be
lengthened to increase the force
when tightening a connection
(e.g. by attaching pipes),
All the materials and auxiliary
materials used (e.g. sealants, installation material and cleaners)
must be free of substances that
can cause stress corrosion cracking (e.g. compounds containing
ammonia or chloride).
Caution!
For tap water installations, sealants
must be authorized and certified by
the DVGW (DVGW seal).

Installation time calculations for the Uponor
MLCP system
General
The function of the calculation is
the costing of construction works
and the generation of an offer.
Thereby a tender specification is
produced in which the construction
work required is described in detail.
The general conditions for the calculation are specified in the current
VOB (General technical regulations)
part C DIN18380: "VOB assignment
and contract policy for for building
works and supplies - part C: Heating systems and central water heating installations" and DIN 18381:
"VOB assignment and contract policy for for building works and supplies - part C: Gas, water amd sewage plumbing works inside of buildings"
Installation times contain the following work:
Preparation of tools and supplementary equipment at the
building site

To prepare a bill of quantities
The supplementary services specified above should be listed separately in the tender. The following
specified installation times are
based on the practical experiences
of Uponor users. Furthermore the
calculation methods in Germany
differ greatly from state to state or
within different regions. Due to this
the following compiled installation
times can represent only an approximate costing basis. You can get
more accurate statistics from the
responsible trade associations,
which have access to extensive
data.
Before use all specifications are to
be checked for correctness by the
responsible engineer/plumber.
Uponor does not take liability for
the correctness of the specifications
or for any possible consequential
damages, which arose or can arise
due to incorrect guidelines, except
for gross negligence or if deliberately wrong data were supplied by
Uponor or their agents.

Certificates
According to DVGW worksheet
W 542 a minimum useful life of
50 years must be proven for multilayer composite pipes used in tap
water distribution systems. For this
purpose an independent testing
institute runs a series of tests in
order to produce an internal pressure creep rupture diagram. For
Uponor this report was produced by
the South German Plastics Centre in
Wurzburg (SKZ). Along with other
tests, the internal pressure creep
rupture diagram forms the basis for
24
DVGW issuing a mark of approval
for Uponor with all associated connectors. Together with the test
institute and DVGW, Uponor works
continuously on the testing of the
pipe system in accordance with all
relevant DVGW worksheets.
DVGW certification permits the use
of the Uponor MLCP systems in tap
water installations in accordance
with the requirements of DIN 1988
TRWI (Technical regulations for
drinking-water installations) All
components coming into contact
with tap water are materials and
articles in the sense of the German
Foodstuff and Consumer Goods
Act. The Uponor MLCP system corresponds to the recommendations
of the German Federal Board of
Health (KTW recommendation), and
through the DVGW mark of approval is also accordingly reviewed and
recognized.
The brass alloy used for the Uponor
MLC fittings corresponds to DIN
50930-6 and fulfils the requirements of the German tap water
directive (TrinkwV).

Protection of tap water
Measures for inhibiting the
growth of legionella
Conditions must be established that
inhibit an unhealthy concentration
of legionella in hot water tank
systems and their attached warm
water distribution systems.
Legionella is rod-shaped bacteria,
which naturally occur at low concentrations in fresh water e.g.
lakes, rivers and occasionally also in
tap water. Approximately 40 forms
of the legionella bacteria are
known. Some legionella forms can
cause infections through the inhalation of contaminated aerosols
(fine water droplets) e.g. while
showering or through moisturizers
in air-conditioners. For people with
health problems e.g. weakened
immune system, chronic bronchitis
etc. this can lead to pneumonia
(legionella pneumonia or legionnaire‘s disease) or to Pontiac fever.
According to DVGW worksheet
W 551 the infection risk is a direct
function of the temperature of the
water from the tap water installation.
The temperature range in which
increased the legionella growth
appears is appropriate between 30 °C
and 45 °C.
Based on the present level of knowledge, the workpaper describes the
necessary technical measures for the
reduction of legionella growth in tap
water installations. Additional measures
are described for the rehabilitation of
contaminated tap water systems.
Circulation systems
Warm water distribution systems in
which warm tap water is constantly
available at the taps must maintained permanent hot water circulation. For the operation of circulation systems, the conditions as stipulated in DVGW worksheets W 551
and W 553 must be maintained in
order to avoided the above mentioned health risks.
the other hand a sufficient warm
water volume flow must be present
in all circulation lines. The DVGW
worksheet recommends the operation of a circulation system with a
water temperature of at least 57 °C
at the end of each return line. The
required flow rates are calculated in
accordance with DVGW worksheet
W 553.
Requirements
This worksheet contains three calculation procedures:
The complete warm water distribution system is to be operated in
such a way that on the one hand
the warm water leaves the tap water
heater with at least 60 °C and
returns to the heater with a temperature loss of no more than 5 K. On
26
A short procedure for small
systems (e.g. one and two family
houses), with which no calculations must be made.
A simplified procedure for all
system sizes with the goal of
supplying a calculation method
which supplies sufficiently accurate results for the draft and
the implementation without
excessive effort.
A differentiated procedure for
all system sizes with the goal
of achieving a better approximation of the real operational
conditions, particularly for large
systems.
The mentioned calculation methods
should be taken from the DVGW
worksheet W 553. The Uponor HSE
calculation software is available for
these calculations.
Uponor „Aquastrom T plus“
Thermostat preset for circulation conduit
Uponor “Aquastrom T plus” is a preset thermostat for circulation conduit that conforms to DVGW worksheets W551 and W553. It regulates
the circulation water temperature in
the recommended range of 55 °C to
60 °C (max. control range 40 °C to
65 °C; accuracy +/- 1 °C). The
valve automatically supports thermal disinfection. The volume flow
rises approximately 6K above the
set temperature and reduces itself,
independent of the temperature
set, starting from approximately
73 °C on the remaining volume
flow. The valve thereby optimally
supports the thermal disinfection of
the circulation system. The maximum volume flow can be preset and
locked, independent of the temperature set. The valve is made from
red brass and is equipped with a
drain valve with a hose mounting
that allows the circulation branch
line to be emptied for maintenance
purposes. Temperature monitoring is
possible with thermometers or
temperature sensors. The temperature setting is protected against
change by a seal cover. The temperature value set can still be read.
Max. operating temperature: 90 °C
Nominal pressure: 16 bar
Factory settings:
Temperature: 57 °C
Volume flow setting: DN 15: 2.0
DVGW certified
Benefits
Automatic thermal regulation of the volume flow
Supports thermal disinfection
Volume flow rises approx. 6 K above the temperature set, thus quickly reaching the
disinfection temperature in the branch line
Restricted above 73 °C, the volume flow is again normalized in order to ensure disinfection of additional components
High corrosion resistance
Temperature setting can also be read with a seal cover installed
Later sealing is possible
Temperature monitoring with thermometer or temperature sensor (accessories) is
possible for the incorporation in building control technology
The maximum volume flow can be preset and locked independent of the set temperature and can be shut off for maintenance.
Integrated drain valve with hose connection
Use of trace heating
The Uponor Unipipe MLC pipe is
suitable for use with trace heating.
The inner aluminium pipe ensures
uniform heat distribution around
the pipe, the customary temperature limitation of 60 °C by the manufacturer is to be respected. The
fixing of the heating band is to be
done according to the manufacturer’s instructions, whereby the
Uponor Unipipe MLC pipe is to be
classified as a plastic pipe.
You must make sure that the water
can expand correspondingly if
Uponor Unipipe MLC pipes with a
self-regulating heating band are
permitted. If this is not the case,
e.g. as with tank outlets to the
warm water distributor, short lines
to the usage points or with house
connection lines that only bypass
one story, damage of the Uponor of
pipe due to the high increase in
pressure cannot be ruled out.
For these cases suitable safeguards
are to be taken, e.g. the installation
of a suitable safety valve or expansion vessel.
Note:
The pressure increase of the components due
to the use of heating tape is to be closely
watched. Suitable safety precautions are to be
planned that ensure pressure equalization.
The manufacturer’s assembly guidelines and
installation notes for the self-regulating heating band must be observed.
27
Connection to instantaneous water heaters, hot water tanks
and mixer
Connection to a instantaneous
water heater
using electronically controlled
equipment to heat tap water.
Due to their construction, hydraulically controlled, electrical and gas
fired flow heaters can build up high
temperatures and pressures, both in
normal operation and as a result of
a failure, which can cause damage
to the pipe system. The Uponor
MLCP system may only be directly
connected to electronically controlled equipment. The manufacturer’s
instructions must be observed when
Connection to a hot water tank
Generally it must be ensured when
connecting hot water tanks (particularly with direct fired hot water
tanks, solar storage tanks and special constructions) that in normal
operation as well as in the case of a
failure, the operation limits of the
Uponor Unipipe MLC pipe are not
exceeded. This applies in particular
to the maximum warm water outlet
temperature, which is to be checked
at start-up or be obtained from the
manufacturer. In the case of doubt,
suitable safety precautions are to be
taken (e.g. installation of an industrial water mixing valve).
Mixer connections
Fitting connection installation must
be torsion-proof (e.g. by fixing the
press tap elbow on mounting brackets or mounting plates).
Humidity protection
The humidity protection required in
sanitary facilities is regulated by
DIN 18195-5 “Water-proofing
against non-pressing water”. The
following implementations are limited to humidity protection within
the area of sanitary fittings and wall
bushings, e.g. within the area of dry
lining panelling.
1 Dry area
2 Wet area
Wall bushing
seal with flexible
silicone
2
Each sanitary facility can be divided
in two “humidity classes”:
1
Wall bushing seal
with stationary
seal ring and
integration into
the surface seal
2
Humidity protection in the area
of sanitary fittings and wall
penetration
With concealed fittings, a seal must
be made to the brick-work or the
opposite dry lining panelling with
a suitable humidity seal. The tiler
integrates these in accordance with
the generally accepted rules of
technology into a surface seal. The
same applies to wall bushings for
28
equipment connections with surface
mounted fittings, e.g. showers and
bath tubs.
Due to moisture build-up (condensation), particular at the cut-out
sites in dry lining panelling, e.g. for
urinal controls, a seal against mois-
ture penetration must be applied
to building material surfaces. All
other wall penetrations within the
dry area (e.g. against the ceramic
facings/tiles) can be sealed with
neutrally hardening sanitary silicone.

Pressure testing the tap water installation
As for all tap water installations, a
pressure test in accordance with DIN
1988-2 is also to be run for the
Uponor MLCP system. Before the
pressure test, all components of the
installation must be freely accessible
and visible in order to be able to
locate unpressed or incorrectly pressed
fittings. All open pipes are to be closed
with Uponor pressure test plug MLC
or metal screw plugs, caps, blanking
plates or blind flanges. Equipment,
pressurized tanks or tap water heaters
are to be separated from the pipes.
It is recommended to perform the pressure test with compressed air or an
inert gas if the pipe system is to remain
unfilled after the test. At the final
inspection the pressure test and flushing must be done with water in accordance with DIN 1988-2.
Pressure test with compressed air or inert gas
The pressure test with compressed
air or inert gas is to be run in accordance with the generally accepted
rules of technology in two steps, the
leak test and the strength test. With
both tests, before starting the test
period, you must wait for temperature equalisation and steady-state
condition after pressure build-up.
Leak test
A visual inspection of all pipe connections is to be made before the
leak test. The pressure gauge used
for the test must have an accuracy
of 0.1 bar in the display range for
the pressure being measured. The
system is pressurised with a test
pressure of 110 mbar. For a system
volume of up to 100 litres the test
period must be at least 30 minutes. The required time is extended by a further 10 minutes for
every additional 100 litres. During
the test no leakage may appear at
the connectors.
Strength test
The strength test is to be run following the leak test. Here the pressure is raised to a maximum of 3
bar (pipe dimension ≤ 63 x 6 mm)
or a maximum of 1 bar (pipe
dimensions ≥ 63 x 6 mm). For a
system volume of up to 100 litres
the test period must be at least 30
minutes. The required time is
extended by a further 10 minutes
for every additional 100 litres.
elapse to allow for the temperature
equalisation between the ambient
temperature and the temperature of
the fill water. If necessary, the test
pressure must be re-established
after the waiting period.
After completion of the pressure
test all fittings are to be checked for
possible leakage. The results of the
pressure test must be recorded in a
report as a record for the plumber
and customer. The forms at the end
of this chapter can be used for this
report.
Pressure testing with water
A visual inspection of all pipe connections is to be made before pressure testing with water. The pressure gauge must be connected at
the lowest point of the installation
being tested. Only measuring
instruments may be used where a
pressure difference of 0.1 bar can
be read. The installation must be
filled with filtered tap water (protect against frost!) and vented.
Shut-off valves before and after
boilers and tanks are to be closed
so that the test pressure is kept
away from the rest of the system.
The system is to be pressurized with
the maximum permissible operating
pressure (10 bar) plus 5 bar (in relation to the lowest point of the system). Check the maximum operating pressure with pressure boosting
systems! A suitable time must
30
Preliminary test
Re-establish the test pressure two
times within 30 minutes at intervals
of 10 minutes. After a further 30
minutes the test pressure must not
have dropped by more than 0.6 bar.
Main test
The main test is to be run directly
following the preliminary test. The
pressure test is considered to have
been passed successfully if the test
pressure has not dropped by more
than 0.2 bar after a further two
hours.

Pipe line flushing
to be flushed using the water method and local supply pressure. The
procedure for the pipe line flushing
is described in the ZVSHK brochure
“Notes on flushing methods for tap
water installations in accordance
with TRWI 1988”. This brochure can
be obtained from the German Central Association of Plumbing, Heating and Climate-Control System
Engineers (ZVSHK), Rathausstrasse
6, 53757 St. Augustin. Details and
general information on flushing
with water can be taken from the
brochure. Under point 4.1 the brochure states:
“The pipes must be flushed as soon
as possible after installation. The
tap water used for the flushing
must be filtered (filter in accordance
with DIN EN 13443-1).”
The total system is to be flushed
thoroughly as soon as possible after
installation of the pipes and following the pressure test. Filtered tap
water (filter in accordance with
DIN EN 13443-1) is to be used as
flushing liquid. In order to ensure
an unlimited operational reliability,
flushing must remove all contamination and installation residue from
the interior surfaces of the pipes
and system components, established the quality of the tap water
as well as inhibit corrosion damage
and malfunctions of the fittings and
components. In general two flushing methods can be used:
Flushing with an air water
mixture in accordance with
DIN 1988-2
In order to protect sensitive fittings
(e.g. solenoid valves, flushing
valve, thermostats etc.) and equipment (e.g. tap water heater)
against damage from flushed foreign matter adaptors should be initially installed in place of such
components. Such components
should only be installed after the
system has been flushed. Built in
fine-meshed sieves installed in
front of fittings that cannot be
removed or bypassed are to be
cleaned after flushing. Aerators,
nozzles, flow limiters, shower heads
or shower handsets must be
removed from the remaining
installed fittings during flushing.
This procedure be based on a pulsating flow of water and air and is
described in detail in the “Tap water
supply systems; materials, components, appliances, design and
installation (DVGW code of practice)” DIN 1988-2 section 11.2.
Suitable flushing equipment is to be
used. This flushing procedure
should be used if flushing with
water is not expected to produce a
sufficient flushing effect.
Flushing with water
If no other flushing method is contractually agreed upon or emanded,
the Uponor tap water pipelines are
The manufacturers’ installation
instructions are to be followed for
concealed thermostats and other
sensitive fittings that cannot be
removed during flushing. All maintenance fittings, floor shut-off
valves and pre-shut-off valves (e.g.
angle valves) must be fully opened.
Possibly built-in pressure reducers
must be fully opened and only be
adjusted after flushing.
Depending on the size of the system and the pipe routing, the
installation can be flushed in sections. In this case the flushing
direction and sequence should be
from the main isolation valve in sections and branches (actual flush
section) from the nearest to the
furthest branch. One floor after the
other is to be flush beginning at the
ascending pipe end.
Within the story and single supply
lines at least as many usage points
specified as a guideline in the
following table for a section being
flushed are to be fully opened
one after the other for at least
5 minutes. This is to be repeated
for each story. Within the story the
usage points, beginning with the
usage point furthest away from the
ascending pipe are to be fully
opened. After a flushing period of
5 minutes at the flushing point last
opened the usage points are closed
one after the other in reverse
order.
For the Uponor Unipipe MLC pipe the following guidelines for the minimum number of usage points which are to be
opened in relation to the largest inside diameter of the distribution conduit must be observed:

is a complete system containing
many components. This opens up
various connection possibilities.
They are suitable for single or
double pipe connections and can
be quickly and securely connected
to all common radiators, whether
directly out of the floor or wall.
The plus of flexibility: You can use
any pipe installation method.
Convince yourself of the variety
of the Uponor MLCP system with its

Fields of application
All heating system components
can be connected using the highquality Uponor Unipipe MLC pipes
with an outside diameter of
14-32 mm in coils and 16-110 mm
in straight lenghts together with
suitable system components such
as press and compression fittings.
The possibility of supplying pipe
dimensions of up to OD = 110 mm
permits their use as cellar distribution and house connection lines in
larger heating systems. The Uponor
MLCP system can be used from the
heat generator over the distribution
conduits and house connection
lines up to the connection to the
heat consumer.
With the following methods you
can realize trouble-free heating
water distribution using the
Uponor MLCP system:
Single-pipe heating system
Double-pipe heating system
Tichelmann system
Installation possibilities – Double-pipe heating system
The double-pipe heating system
with its variations for the single
and multi-family dwelling sectors is
particularly suitable for low-tem-
perature heaters. With this installation variation the radiators are
connected to the supply and
return. All radiators have approxi-
mately the same supply temperature. A benefit is the fast and easy
adjustment of the double-pipe
heating system.
Double pipe heating system
with manifold
With this installation variation the
heating water distribution is connected to the radiators by means
of single inlets from a central manifold. The Uponor manifold is in turn
connected to the house connection
line of the heat generator.
Two-pipe system with radiator
connection tee and elbow
Using the two-pipe system with
radiator connection tee, ring loops
with one or more radiators are connected individually to a central distributing manifold. A heat meter
can be fitted to the heating distributor, measuring the heat supplied
to the whole apartment.
41
Two-pipe system as a loop
VL RL
When the two-pipe system is used
as a loop, the pipes to connect the
radiator begin and end at the riser.
Double-pipe heating system with
tee connection and cross fitting
VL RL
Beginning from the house connection
line, the heating water distribution is
made by a common ring loop. If the
ring loop runs directly by the radiator,
the radiator connection can be made
with a press connection tee. The last
radiator of the ring loop is connected
by an Uponor press angle bracket. If
the radiator is connected over a single
inlet to the ring loop, the use of a
cross fitting is recommended.
Installation possibilities –
Single-pipe heating system
VL RL
With a single-pipe heating system all
radiators of a heating circuit are connected to a closed ring loop. In this
case ring loops are connected directly
by a T-piece to the house connection
lines of the heat generator. If there
are several ring loops, these can be
connected to the Uponor heater distributor. The distributor is in turn connected to the house connection line
of the heat generator.
As a rule, the adjustment of singlepipe heating systems is usually complex. With a single-pipe heating sys-
tem the temperature gradient
between the radiators, i.e. the
decreasing supply temperature from
radiator to radiator, must be consid-
ered when dimensioning the heating element in the form of an area
surcharge. Benefits are a result of
lower material and assembly costs.
return for each radiator is approximate equal. That means that the
radiator with the longest supply
has the shortest return. Thus a
more uniform pressure drop in the
individual stages is achieved.

are arranged in such a way that the

with the Uponor pressure test plug.
Water heaters are to be checked
with a pressure of 1.3 x the total
pressure (static pressure) of the system; however, at least 1 bar excess
pressure must be reached throughout the system. Only pressure
meters may be used that permit the
accurate reading of a 0.1 bar pressure change. The pressure meter is
to be connected, if possible, to the
lowest point of the system.
The heating system is to be filled
slowly and completely vented (protect against frost!). This can be
done quickly and with little effort

water. If necessary, the test pressure
must be re-established after the
waiting period.
The test pressure must be maintained
for 2 hours and may not drop by
more than 0.2 bar. No leakages may
appear during this time. As soon as
possible after the cold water pressure
test the system is heated to the highest calculated heating water temperature to check whether the system
also remains leak-free at high temperature. After the system cools
down the heating pipes and connections are to be checked for leaks.

All tanks, equipment and fittings, e.g. safety valve and expansion tanks, which are not suitable for the pressure test, must be removed
from the system during the test period. The system is filled with filtered water and completely vented. During the test a visual inspection
of the pipe connections must be made.

Calculation example
The selection of the respective pipe
dimension depends on the required
mass flow rate (volume flow) of the
particular stage. Depending upon
the dimension of the pipe’s OD x s,
the flow rate v and the pipe friction
resistance R change.
If the pipe selected is too small, the
flow rate v and the pipe friction
resistance R rise. This leads to higher
flow noises and to higher current
usage of the circulation pump.
During the design of the pipeline
we recommend that you not to
exceed the following approximate
velocity values:
Radiator connection pipe:
≤ 0.3 m/s
Radiator distribution pipe:
≤ 0.5 m/s
Heating system house connection
and cellar pipes:
≤ 1.0 m/s
The pipe network has to be planned
in such a way that the flow rate
decreases uniformly from the boiler
to the furthest radiator. The guidelines for the flow rate are to be
observed.
The maximum transferable thermal
output QN is to be entered in the
following tables under consideration
of the maximum flow rate, in relationship to the type of pipe, spread
ΔT and the pipe dimension OD x s.

Technical notes on the Uponor MLCP system
Fire protection
The main goal of fire protection is
to hinder fires. If a fire occurs, then
the second goal of fire protection is
to minimize damage.
In the context of building legislation the State establishes the preconditions in order to ensure public
safety and prevent danger from
destructive fires.
The model building code (MBO) is
the basis for all building regulations,
including fire protection measures.
The building codes of
the individual German States are
oriented on this model building
code.
According to MOB 2002 section 14
“Fire protection” (wording and contents also apply in the individual
German States) pipes that pass
through firewalls and stairwells, as
well as walls and ceilings that must
meet fire resistance grading, may
only be installed if spreading of fire
56
or smoke is not a risk or if provisions have been taken against such
possibilities.
For example, when installing
Uponor Unipipe MLC pipes (building material class B2 in accordance
with DIN 4102) with an outside
diameter OD ≤ 32 mm spreading of
fire and smoke is not a risk if the
area between pipe and the remaining cross-section of the opening is
completely filled in with non-combustible, shape-retaining building
material (closing the cut-outs with
mortar and concrete).
If mineral fibres are used, they must
have a melting point of more than
1000 °C. In residential buildings the
following basic fire protection principles apply:
Along with the fire protection
requirements, sound and thermal
protection requirements as well
as the thermal expansion/con-
traction of pipe systems must be
considered when installing pipes
through openings in walls or
ceilings.
Fires and smoke may not
spread into other ventilation
zones within the required fire
resistance grading
(e.g. F 90 = 90 minutes).
All building materials must fulfil
the building material class
B2 = normal inflammable.
The high requirements of a fire prevention concept that guarantees
health and life can only be realized
with the cooperation of all parties
taking part in the building project
and with a tender and a construction supervision that is matched to
the project.
Uponor offers comprehensive fire
prevention solutions for the composite pipe system.
Sound protection
DIN 4109 with the supplementation table A1 determines the minimum sound insulation required in buildings for
different needs as well as with reference to the noise source. The following maximum sound pressure levels in dB (A)
are permissible:
Excerpt from DIN 4109 with supplementation table A1:
Source of noise
Water installations
(Water supply and waste water
systems together)
other equipment and appliances

≤ 30 3)
≤ 35 3)
Single, brief peaks, which occur during actuating the fittings and equipment in accordance with table 6 (opening, closing, rearranging,
interrupting etc.), are not to be considered at present.
Contractual conditions for the fulfilment of permissible sound pressure levels of the installation::
- The final planning documents must consider the sound insulation requirements, which means, among other things, that the components must
have the required sound insulation certifications.
- Furthermore the responsible chief engineer must be designated and consulted for a partial acceptance before closing or covering the installation
The ZVSHK instruction leaflet “Sound insulation” provides more information and can be obtained from the “German Central Association of
Plumbing, Heating and Climate-Control System Engineers (ZVSHK), Rathausallee 6, 53757 Sankt Augustin”.
Higher values of around 5 dB (A) are permissible with ventilation equipment, as long as it relates to continuous noise levels without any
noticeable single tones.
Under “other equipment and appliances” is understood to mean, for example, heating systems including heat distribution.
Note:
At present the maximum installation noise level LIN ≤ 30 dB (A) in house construction corresponds
to the generally accepted rules of technology and actual case law. The purpose of all sound proofing measures is it to protect people in common rooms against unreasonable harassment by sound
transmission. The following are to be understood as areas that need protection in accordance with
to DIN 4109 with supplementation table A1:
Living space, including halls
Sleeping areas, including overnight accommodations in pensions and bed areas in hospitals and
sanatoriums
Classrooms in schools, universities and similar facilities
Office space (excluded open-plan offices), consulting rooms, meeting areas and similar work areas

Example:
The area in need of protection in
dwelling A is to be protected against
the noise of the “sound from area B”
and the other way around.
Wall and ceiling weights are given
pursuant to DIN 4109
Deviations are only possible with a
sound related proof of suitability
Dwelling ceiling partition

Single-shell installation wall

m’ > 220 kg/m2
57
Sound insulation in accordance with VDI 4100
In addition to the requirements of
DIN 4109 an increased sound insulation can be contractually agreed
upon in accordance with VDI 4100.
This contains similar sound insulation levels as in DIN 4109 – however with other sub-sections. In
this VDI guideline are also useful
tips for practical sound insulation
planning. Apart from their function
as limits for construction acoustics,
the sound insulation levels specified above are also of importance
as acoustic quality characteristics
for sanitary products. A product
that meets the sound insulation
levels of SSt II or SSt III ensures a
high measure of noise reduction
and an additional safety margin for
use in the construction of living
and sleeping areas as well as for
instruction and work areas.
The VDI 4100 specifications are as
follows:
Sound insulation level I is no
longer state of the art and is
therefore irrelevant
Sound insulation level II
corresponds to the minimum
DIN 4109 requirement of
LIn < 30 dB (A)
With LIn < 25 dB (A) sound
insulation level III ensures an
increased acoustic comfort
58
However, if VDI 4100 should be
agreed upon in the construction
of double and terraced houses,
then the basic values must all be
reduced by 5 dB (A). If VDI 4100
is contractually specified, sound
insulation requirements of maximum 30 dB (A) within personal
living areas must be maintained!
If waste water noises are regarded
separately, then the basic values
must be reduced by 5 dB (A). This
means that all installations within
personal living areas must be
accurately coordinated with one
another and that all doors must
also accommodate these conditions. The specifications represented here refer to common
rooms in the sense of state building codes, which makes the specifications more comprehensive
than the areas needing protection
pursuant to DIN 4109.

Thermal protection
Building insulation helps to minimize the energy consumption and
lower the accompanying waste gas
quantity as well as the fuel and
power costs. In particular, high
potentials savings can be realized in
building equipment for energy production and distribution.
The German Energy Saving Directive (EnEV) demands the limitation
of the heat emission of heat distribution and warm water pipes.

or a wall between two heated areas.
With the use of insulating materials with a heat
conductivity other than λ = 0.035 w (m x K) the
insulating layer thicknesses are to be recalculated. The conversion is to be done using computing methods and nominal values provided
by the generally accepted rules of technology.

Insulating solutions with pre-insulated Uponor Unipipe MLC pipes
Pre-insulated pipes are available
for the Uponor MLCP system in
order to be able to meet the
requirements of the German Energy Saving Directive (EnEV) during
60
installation. These pipes enable a
time saving installation as the time
intensive insulation and the gluing
together of joints on the building
site is not necessary. Due to its PE
film covering, the pre-insulated
Uponor Unipipe MLC pipe is able
to withstand the mechanical loads
they are subject to on the building
site.

Pre-insulated Uponor Unipipe MLC pipes cold tab water (DIN 1988-2)
Cold tap water systems are to be
protected against an inadmissible
temperature rise and, if necessary,
against condensation. Cold tap
water pipes are to be placed at a
sufficient distance from heat sources. If this is not possible, then the
pipes are to be insulated in such a
way that the quality of the tap
water is not impaired by a temperature rise.
With insufficiently insulated cold
water pipes condensation can form
on the insulating layer and unsuited
materials can become saturated.
Therefore closed-cell or comparable
materials with a high water vapour
diffusion resistance should be used.
All joints, cuts, seams, and end
points are to be vapour sealed.
The following table shows the minimum insulating layer thicknesses
pursuant to DIN 1988-2, using an

Installation method by Z-dimension
As a basis for efficient planning,

offers the plumber considerable
advantages as far as ease of work
and cost savings are concerned.
between fittings. Through exact
clarification of the pipe routing and
coordination with the architect,
planner and chief engineer in
advance of the actual installation,
large sections of the system can be
preassembled for cost-effective
installation.
The basis for the Z-dimension
method is a uniform measuring
method. All the lines to be installed
are measured over the axial line by
measuring from centre to centre
(intersection of the axial lines).
(Example: LR = LG - Z1 - Z2)
With the help of the Z-dimensions
of the Uponor press fittings, the
plumber can quickly and easily
calculate the exact length of pipe

Note:
In this context make certain
that the bending radius (e.g.
in the area between floor and
wall) does not fall below the
minimum radius. If the minimum bending radius is not
reached, a suitable fitting (e.
g. a 90° press elbow) must be
used.

Consideration of the thermal length variation
The thermal length variations, that
result due to changing temperatures, must be considered when
designing pipe routes. Temperature
difference ΔT and the pipe length L
play a decisive role in the length
variation.
For all installation variations the
heat expansion of Uponor Unipipe
MLC pipes must be considered in
order to avoid excessive stress in
the pipe material and damage to
the connections, in particular by
free laid pipes such as radiator
connecting pipes out of the floor
or from the baseboard as well as
with cellar distribution and house
connection lines. For pipes that
are laid in the wall under plaster or
in the screed, the heat expansion
is compensated for by the insulation in the area of direction
change.
The following equation is used to
calculate the length variation:
Δl = a × L × ΔT

Type and distance between the pipe
fastenings is dependent on pressure, temperature and medium. The
dimensioning of the pipe supports
is to be determined from the total
mass (pipe weight + medium weight
+ insulation weight) in accordance
with the generally accepted rules of
technology. It is recommended to
set the pipe supports, if possible, in
the proximity of the fittings and
connectors.
Pipe installation onto the
raw floor
When installing pipes on a concrete
floor the generally accepted rules of
technology are to be observed. The
sound insulation is to be installed in
accordance with DIN 4109 “Sound
protection in above ground construction”. The insulation regulations pursuant to the German Energy Saving Directive EnEV and in
accordance with the Codes of practice for tap water installations
(TRWI) DIN 1988-2 are to be
observed. Furthermore, the mobility
of pipes during thermal expansion is

to be taken into consideration (see
section “Thermal length variation”).
If screeds are applied on insulating
layers (floating screed), DIN 185602 “Floor screeds in building construction” is to be particularly followed. In DIN 18560-2: 2004-04
the following additional declarations are made (point 4.1 loadbearing substrate):
“In order to accept the floating
screed the load-bearing substrate must be sufficiently dry
and have an even surface. The
smoothness and tolerance must
correspond to DIN 18202. It may
not contain any peaks, pipes or
anything similar that can lead to
sound bridges or fluctuations in
the screed thickness.
Furthermore, for prefabricated
heating floor screeds the special
requirements of the manufacturer as to the smoothness of
the load-bearing substrate are to
be observed.
If pipes are installed onto the
load-bearing substrate they

must be fixed. A smooth surface is to be created for the installation of the insulating layer
– at least the sound insulation.
The required construction
height must be planned for.
When installed, the levelling
layer must exhibit a closed
form. Fill may be used, if its
serviceability is proven. Insulating materials may be used as a
levelling layer.
Sealing against ground
moisture and non-accumulating seepage water are to be
determined by the building
planner and be prepared before
installation of the screed
(see DIN 18195-4 and DIN
18195-5)”.
The routing of the Uponor Unipipe
MLC pipes and other plumbing on
concrete floors is to be done nonintersecting, straight and as axially
parallel and parallel to the walls as
possible. The preparation of a plan
before the installation of the pipe
tracks and other plumbing makes
the installation easier.
75
Mounting distances during pipe
installation on a concrete floor
When installing Uponor Unipipe
MLC pipes on concrete floors a fixing distance of 80 cm is recommended. The pipe is to be fixed
within a distance of 30 cm in front
and behind each bend. Pipe crossings are to be fixed. The fixing can
be done using a synthetic plugged
hook for single or double pipe fixing.
When using a perforated tape for
fastening, you must make sure that
the Uponor Unipipe MLCP with/
without protective tube or insulation can freely move. Noise can be
caused by the thermal expansion of
the pipe if it is firmly fixed.
If the Uponor MLC P system is
installed directly in the screed, the
pipe fittings must have suitable
protected against corrosion.
In order to prevent damage to the
screed and floor covering, joints
(expansion joints) are to be placed
in the insulating layer and in the
screed over construction joints.
Uponor Unipipe MLC pipes, which
cross construction joints, must be
sheathed in the joint area at least
with a longitudinally slit Uponor
joint protection tube (20 cm each
side of the expansion joint).

Pipe routing
Pipes and other plumbing in the
floor construction are to be planned

the pipes on concrete floors is to be
done as non-intersecting, straight

the walls as possible. The following
route dimensions for pipes and other plumbing should be maintained:

room at a temperature of up to
260 °C. Therefore the Uponor Unipipe MLC pipe and all other temperature sensitive plastic components must be protected. The
Uponor system edging strips can
not be used with mastic asphalt. For
this application there are special
bitumen suited mineral fibre edging
strips, which are to be procured by
the customer.
The Uponor MLCP system can be
used without problems with mastic
asphalt by observing following precautions.
The un-insulated Uponor Unipipe
MLC pipe must at least be placed in
a protective tube. The use of preinsulated Uponor Unipipe MLC pipe
is recommended in order to fulfil
the requirements of DIN 1988 and
the German Energy Saving Directive
(EnEV).
The Uponor MLCP system is to be
filled with cold water and pressurized in order to be able to locate
any possible damage caused by the
laying of the mastic asphalt.
Caution:
Cold water must constantly
circulate through the pipe in
order to be able to find a
any damage caused by the
pouring of the mastic
asphalt.
The installation of mastic asphalt
screed over Uponor Unipipe MLC
pipes can be carried out by observing the following floor construction
(from bottom to top):
mastic asphalt-resistant edging strip
mastic asphalt
overlapped rib pasteboard or
wool felt pasteboard
mastic asphalt-resistant mineral plates
levelling layer
bounded fill
concrete floor
pre-insulated Uponor Unipipe MLC pipe
Install the Uponor Unipipe MLC
pipe in a protective tube or preinsulated Uponor Unipipe MLC
pipe on top of the concrete floor
Perlite fill as levelling layer to
the upper edge of the protective
tube or pipe insulation
Mineral fibre mat at least 20
mm thick (mastic asphalt suited)
WLG 040
Mastic asphalt, pouring temperature approx. 260 °C
System components (pipes and fittings) that can come into contact
with mastic asphalt (e.g. when
installed under a radiator), are to
be sheathed with 50% insulation
(at least 20 mm thick) that is rated
as fire protection classification A1
(non-combustible) pursuant to DIN
4102 (e.g. with mineral fibre insulation sheath RS 835/Conlit 150
P/U). The non-combustible insulation must fully enclose the Uponor
Unipipe MLC pipe and the Uponor
MLC fittings. The joints of the
insulation sheaths and the transition points of the heat resistant
thermal or sound insulation (mastic
asphalt suited) to the non-combustible pipe insulation are to be
taped with a temperature-resistant
adhesive tape (e.g. Aluminium
adhesive tape). The insulation
sheaths around the pipe can also
be alternatively fixed with binding
wire.
These measures protect the Uponor
MLC pipe system against radiant
heat and against direct contact with
the mastic asphalt. Pipe parts
extending from the floor must be
protected against direct contact
with the mastic asphalt and/or the
radiant heat.
After hardening and cooling of the
mastic asphalt the visible mineral
fibres in the area of the Uponor
Unipipe MLC pipe or the radiator
connection are to be removed. The
use of a floor rosette is recommended for a clean finish.
Caution:
The Uponor MLCP system
must not come into contact
with the mastic asphalt. The
precautionary measures
described are to ensure that
the maximum temperature
on the pipe surface does not
exceed 95 °C! DIN 18560
“Floor screeds in building
construction”, the specifications of the mastic asphalt
manufacturer, the diligence
and care of the mastic
asphalt supplier, DIN 4109
“Sound protection in above
ground construction” as
well as the generally accepted rules of technology
apply.

Transport, storage and installation conditions
78
General
Operating temperatures
The Uponor MLCP system is conceived in such a way that when
installed as directed a maximum of
system security is achieved. All system components are to be transported, stored and installed in such
a way that a perfect functioning of
the installation is ensured. The system components should be stored
together grouped as to their functions in order to avoid confusing
similar components with each other.
In addition to the following notes,
the directions in the respective fitting instructions of the individual
system components and tools are to
be observed.
The permissible installing temperature for the Uponor MLCP system
(pipes and fitting) is between
-10 °C and +40 °C. The permissible
temperature ranges for the pressing
tools are to be taken from the
respective operating instructions.
The Uponor Unipipe MLC pipes are
to be protected against mechanical
damage, contamination and direct
sunlight (UV radiation) during
transport, while stored and when
being installed. Therefore, if possible, the pipes should be kept in the
original packaging until installed.
This also applies to unused components that are intended for later
use. The pipe ends are to be
plugged until used in order to prevent dirt entering the pipes. Damaged, buckled or distorted pipes
may not be used. Pipe cartons
with coils can be stacked up to a
maximum height of 2 m. The pipe
in straight length is to be transported and stored in such a way
that it cannot bend. The relevant
Uponor storage regulations are to
be observed.
Uponor Fittings
Uponor MLC fittings may not be
thrown or otherwise inappropriately handled. In order to avoid
damage and contamination, the
fittings should be kept in the
original packaging until installed.
Damaged fittings or fittings with
damaged O-rings must not be
installed.
Mounting instructions
The installer must read and
understand the instructions prior
to mounting, and must observe
them.
When you receive the Uponor composite pipe system, you get proven
quality. Please, nevertheless, check
all the components for any possible
transport damage before fitting.
Observe the rules of good technical practice
The applicable technical rules,
DVGW worksheets, and German
building regulations must all be
observed in order to properly install
the Uponor composite pipe system.
The pipes must be laid in accordance
with generally recognised codes of
pratice. In addition, local rules, installation regulations, accident prevention regulations and safety specifications must all be observed. Please
also observe the assembly instructions that are included with the product and which are also available for
download from www.uponor.com.
