Fancoil QZSC
QZSC " Satellite " Fan Coil Unit - Description
Basic unit
Filter
Consists of self-supporting panels in hot dip galvanized
steel, which are insulated with class 1 anticondensating
lining.
The filter is made of washable synthetic polypropylene
with galvanized steel frame and mesh. Easy access to the
filter for cleaning operation
Fandeck
Consists of extremely noiseless centrifugal fans in
galvanized steel with two impellers and a directly
coupled single phase, five speed motor, three of them
are connected, 230V 50Hz with permanently installed
condensor, insulation class B.
Heat exchanger
Constructed in 3/8” dia expanded copper tubes with
aluminium fins. The steel headers have 1/2” female
connections and extra 1/8” tapping for drain and air vent.

Acoustic Data
Often sound levels are the key influencing factor in the selection of equipment. The notion sound power is often
confused with the notion sound pressure. The two notions can be defined as follows :
Sound power (Lw)
Sound power is the output required producing
sound pressure waves. It is not, as such, directly
measurable.
Sound power is established by measuring the
sound pressure on the inner surface of a sphere
placed around the source. It is measured and
stated in Watts.
Sound power is therefore a measurement, which
is not dependent on area or distance, and it is
used as a basis for all acoustic data.
Sound preassure (Lp)
This is the alternating pressure produced by
waves from a sound source. It is a measure of the
noise level or noise intensity.
Sound pressure is dependent on the average
absorption factor of the room, distance from
the sound source, the position of the unit in the
room, the occupation and is therefore not suitable
for calculations of sound propagation or spread.
An explanatory example:
The sound power level can be compared with the heating capacity of a boiler. This capacity will remain the same
regardless of the thermal characteristics of the installation.
The sound pressure level can be compared with the temperature obtained in a room supplied from the boiler. Obviously,
the temperature will vary depending upon the room characteristics and so it is with sound pressure.
Therefore, accurate comparisons between competing equipment should always be made, in the case of the boiler, by
comparing boiler capacity and in case of fan coil units by comparing the sound power levels.

Example of a typical application:
Office 5,25 m x 4,15 m x 2,75 m
=> Room volume : 60m3
Room absorption : 6 dB
QZSC-23 :
Outlet configuration : 2 x dia 200 mm inlet and outlet, Flexible acoustic ducting dia 200 mm, L = 2,5 m, Room outlet type
'linear slot diffusers' (4 slot), L = 1,2 m, gives an attenuation factor = -10dB
Estimated sound power level in the room : 53 dB(A) - 16dB = 37 dB(A)
Sound level achieved in the room NR 32

A sensible figure higher than a total heat figure shows
that the cooling is obtained without dehumidification,
therefore the capacity to refer is the sensible one.
Other selections are available from our computer
program. Ask your local sales representative. The cooling
selection tables are valid for both systems (2- and 4-pipe).
EWT = Entering water temperature, EAT = Entering air

Practical guidelines
Precautions to be taken before and during
installation
•
•
•
•
•
•
•
•
•
•
•
•
•
Control system
Units are carefully inspected and tested prior to
delivery.
The water system must be carefully designed
and balanced if the fan coil system is to perform
correctly.
The units should be installed in such a way
to allow easy access for maintenance and
adjustments.
It is important that the unit is placed level or
slopes slightly towards the condensate drain side
Sufficient slope of the drain system shall be
assured for a quick condensate removal = 2 %
(min. 2 cm/m).
The inlet water connections for cooling and
heating are always the lower of the coil
connection.
Although units equipped with water control
valves have been carefully checked at the factory,
it is advisable to check the tightness of all pipe
connections on site using a spanner.
Make sure that the condensate will drain off
freely.
Do not connect the drain system directly to
the drainpipe of the main driptray but use
the drainpipe of the auxiliary driptray for the
evacuation of the condensate.
It is recommended to seal the joint between the
unit and the auxiliary driptray with a sealer.
The distance between the air intake side and the
floor or wall should be minimum 100 mm.
Make sure that no shelving or furniture obstructs
free air circulation.
Dispose of packaging material in accordance
with local requirements.
Electrical connections
•
•
•
•
•
•
•
•
•
The voltage of the motor is stated on the
identification label of each unit.
The electrical wiring of the units should be done
by an authorised electrician in accordance with
the local regulations.
The electrical heating elements must only be
factory installed.
The electrical installation should be of permanent
type and the unit protected by means of fuses in
the power supply from the mains.
Incorrect field wiring will cause motor damage.
Always use the same power supply circuit for
the fan coil system (fan coil units, thermostats,
etc. ..)"
Do not connect more than one fan coil unit to one
common speed selector switch.
In master/slave applications, check carefully the
equipotentiality of the electrical connections.
5011GB 2007.01
•
21
When the fans are not running, it is strongly
advisable to ensure that the chilled water supply
to the coils is automatically shut off, to prevent
condensation in and on the unit.
Units equipped with electrical heating elements
must be connected to a regulation with
permanent ventilation.
Starting-up
•
•
•
•
•
•
•
•
•
Check that the coils have been cleaned after the
installation work.
Check the water system and open the valves for
the water supply.
Check that the water connections do not leak.
Open the venting screws and check that there is
no air in the coils.
Equalisation of the pressure drop across the
whole water system is recommended.
Check that the fan impeller rotates freely and in
the correct direction.
Run the fan at high, medium and low speed and
check that no mechanical noise can be heard.
Check that the unit is well secured and does not
vibrate.
Check the performance of the supervisory
system.
Maintenance
•
•
•
•
All motors are tested prior to delivery.
Fläkt Woods
•
•
•
•
•
•
•
Before performing any service or maintenance
operations, turn OFF the main power supply.
Inspect the unit at regular intervals.
The frequency of cleaning the coil and the
driptray depend on local conditions.
The coil should be cleaned on both sides. Use a
vacuum cleaner with a rubber nozzle.
Work carefully to avoid damaging the coil
surfaces.
Check that the drainpipe is clean and not
clogged.
The motor bearings are permanently lubricated
and do not require lubrication.
The standard filters are of the washable type and
should be cleaned when clogged.
Check min. once a month the filter – final
pressure drop is recommended up to 25 Pa.
The frequency of filter cleaning or replacement
is dependent on the dust content in the return
air. (our recommendation : Max. 1 month after
starting-up period and further min. every 3
months)
Fancoil QZSC
Practical guidelines
WARNING!
•
•
•
•
•
The cooling and heating output of the unit will
be reduced if the unit is running with clogged
filters.
Unit mounted electrical heating elements can
influence the sound level of the units.
Dirty/clogged filters will increase the sound level
and are harmful to the operation and workingexpenses of the units.
Prolonged operation with a dirty/clogged filter
may lead to deterioration of the motor.
To avoid breaks caused by ice, please empty the
watercircuit when the roomtemperature goes
down to 0 °C.
