Safety
The ZENOTEC Fire Cube sintering furnace was designed and manufactured after
careful selection of the harmonized standards to be observed as well as other
technical specifications. It therefore corresponds to the state of the art, ensuring
the highest possible degree of safety.
Only materials with known characteristics and melting temperatures may be used.
Check the material safety data sheets if necessary.
Use of the furnace for any other purpose whatsoever such as processing
products other than those intended or handling hazardous substances or
substances posing a health hazard constitutes improper use and must be
agreed upon with Wieland in writing.
Whether or not the materials used in the furnace can potentially corrode or destroy
the insulation or heating elements must be ascertained.
Modifications to system equipment must be agreed upon with
Wieland in writing. It is not permitted to remove, bypass, or shut down safety
devices.
The installation instructions and safety guidelines must be observed. Otherwise,
the furnace will not be considered as being used as designated, and all claims
against Wieland Dental + Technik GmbH & Co. KG will be void.
Opening the furnace when hot (temperature greater than 200/392 °C/°F) can lead
to accelerated wear of the following components: insulation, heating elements, and
furnace housing.
Operating with power sources, products, operating equipment, additives,
etc. that are subject to the Ordinance on Hazardous Substances or cause
risks to the health of operating personnel in any way is not permitted.
- This furnace is designed for commercial use. The furnace must not be used
for heating food, animals, wood, grain, etc.
- The furnace must not be used as a workplace heater.
- Do not use the furnace to melt ice or similar materials.
- Do not use the furnace as a clothes dryer.
Note
See safety instructions in the individual sections.

Caution
Operating the furnace with explosive gases or mixtures, including explosive gases
or mixtures created as a result of heating/drying, is prohibited.
This furnace features no safety technology for processes which produce
combustible mixtures, for example debinding.
13
If the furnace is still used for such processes despite this fact, the concentration of
organic gas mixtures in the furnace must never exceed 3% of the lower explosion
limit (LEL). This pre-requisite applies not only to normal operation but, in particular,
to exceptional situations such as process disruptions (caused, for example, by the
failure of a power unit). You must ensure that the furnace is adequately ventilated
and vented.

Requirements for the Oven Operator
Pos: 48 /TD/OEM-Module/ZENOTEC Fire Cube - Firma Wieland/Anforderungen an den Betreiber der Anlage - ZENOTEC Fire Cube @ 24\mod_1338969649140_51.doc @ 163330 @ @ 1
The set-up instructions and safety regulations must be followed, otherwise the
oven will be deemed to have been used improperly, effectively cancelling any
claims against Wieland Dental + Technik GmbH & Co. KG.
This level of safety when operating the oven can be achieved only if all the
necessary measures have been taken. It depends on the oven operator's diligence
in planning these measures and controlling how they are carried out.
The operator must ensure that
 all harmful gases are removed from the workplace, for example by an
extraction system,
 the extraction system is switched on,
 the workplace is properly ventilated,
 the oven is operated only in a perfect operating condition and, in particular,
that the functions of the safety components are checked regularly.
 the required personal protective equipment is available for and used by the
operating, maintenance, and repair personnel.
 these operating instructions, including the supplier documentation, are kept
near the oven. These instructions must be available at all times for anyone
working with or on the oven;
 all the safety and operating instruction signs on the oven can be read
properly. Damaged or unreadable signs must be replaced immediately,
 oven personnel are informed regularly about all issues involving
occupational safety and environmental protection and are familiar with all
the operating instructions, especially those involving safety,
 a risk assessment is carried out (in Germany, covered by Section 5 of the
Occupational Safety Act) to determine any other hazards that may result
from the working conditions particular to the oven's location,
 all other instructions and safety guidelines that have been determined in a
risk assessment for the workplace are compiled in an operation manual (in
Germany, covered by Section 6 of the Ordinance Regulating the Use of
Operating Equipment).
 operating personnel still in training initially perform their work at the oven
under the supervision of an experienced person. Successful completion of
the training period must be confirmed in writing.
Note
In Germany, the VBG and BGZ accident prevention regulations must be followed.

Symbols:
The international standard symbols for handling packaging are defined in ISO
R/780 (International Organization for Standardization) and in DIN 55 402 (German
Institute for Standardization).
Description
Symbol
Explanation
Fragile
This symbol is to be attached to fragile goods. Goods
marked like this are to be handled carefully and must
not be thrown or tied up.
This side up
The freight must be transported, transshipped, and
stored in such a way that the arrows point upward. The
freight must not be rolled, folded, or stored on edge.
However, the package does not have to be packed on
top of other freight.
Keep dry
Products with this symbol must be protected against
high air moisture, hence, they must be stored under
cover. If particularly heavy or bulky packages cannot
be stored in halls or sheds, they must be covered
carefully with a tarpaulin or similar.
Sling here
The symbol shows only where the sling should be
attached, not the method of slinging. If the symbols are
at an equal distance from the middle or center of
gravity of the package, the package hangs straight if
the slings are the same length. If this is not the case,
the sling on one side has to be shortened.

When setting up the furnace, the following safety instructions must be followed:
31

The furnace must be installed in a dry room in accordance with the safety
instructions.

The table/supporting surface must be flat to enable the furnace to be installed
straight. The furnace must be placed on a noncombustible base (stone,
metal, etc.).

The carrying capacity of the table must be designed to bear the weight of the
furnace incl. accessories.

The floor covering must be made of nonflammable material so that hot
material falling out of the furnace will not cause the floor covering to ignite.
Despite good insulation, the furnace radiates heat from its external surfaces. If
necessary, this heat must be conducted away (a ventilation engineer must be
consulted if required). In addition, the furnace must be positioned a minimum
safety distance (S) of 0.5 m on each side and 1 m at the top away from
combustible materials. In individual cases, more space must be chosen in order to
match the local conditions. The minimum distance away from noncombustible
materials may be reduced to 0.2 m at the sides.
Should gases or vapors escape from the charge, then sufficient air supply and
ventilation at the installation location or an appropriate exhaust gas line must be
provided.
A suitable exhaust for the burner exhaust must be provided by the customer.

We recommend that an exhaust air pipe be connected to the furnace and that the
exhaust gases be conducted away accordingly.
A commercially available metal exhaust gas pipe with NW80 to NW120 may be
used as a flue. It must be routed in constantly ascending form and must be
secured to the wall or ceiling.
Position the pipe centrally above the furnace's flue outlet. The exhaust gas pipe's
connection to the exhaust air pipe must not be airtight, as no bypass effect is
otherwise achieved. This is necessary to prevent an excessive amount of fresh air
from being sucked through the furnace.
Fig. 13: Assembly of a flue (example)
Note
The exhaust gases can only be conducted away if the room is ventilated via a
corresponding air inlet.
Note
The exhaust gas pipe necessitates roofing and bricklaying work on the part of the
customer. The size and variant of the exhaust gas pipe should be determined by a
ventilation engineer. The national regulations of the relevant country apply.

The oven may be put into operation only by qualified persons and in compliance
with the safety instructions.
Read the section on "Safety". When the oven is put into operation, the following
safety information must also be observed to prevent serious injury, damage to the
oven, and damage to other property.
Make sure that the instructions and information in the controller instructions are
observed and followed.
37
The oven may be used only for its intended purpose.
Ensure that only authorized persons remain in the working area of the oven and
that no other persons are put at risk when the oven is put into operation.
Before starting the oven for the first time, make sure that all tools, foreign parts,
and transportation securing equipment have been removed.
Activate all safety equipment (power switch, emergency stop button if applicable)
before putting the oven into operation.
Incorrectly wired connections may destroy electric/electronic components.
Observe the special protective measures (e.g. grounding, …) for components that
are at risk.
Faulty connections can cause the oven to start unexpectedly.
Before you switch on the oven, make sure that you know what to do in case of
faults or emergencies.
Before starting the oven for the first time, check the electrical connections and

A special initial heating phase is not necessary for these heating elements
installed in the furnace. You can begin immediately with the desired heating
program.
During the heating, there may be a disturbing odor, due to the binding agent
given off by the insulating material. We recommend ventilating the furnace
location well during the first heating phase.

Cracks in the insulation
The insulation of the furnace consists of a very high-quality refractory material.
Heat expansion may cause cracks in the insulation even after a few heating cycles.
However, these have no effect on the functioning or quality of the furnace.

Note
During manufacturing residues of Silicium remain existant. At higher temperatures
these result in fine glass bubbles at the surface of the heating element. The
formation of these bubbles begins at tempera-tures above 1550 °C (2822 °F).
Remove any existing bubbles carefully (with a brush or similar) before heating up
the next time. This appearance is no background for a complaint.

Program Entry with/without Gradient
As of controller version 3.xx you can enter ramps either as gradients (e.g. 120°C/h)
or using the "time and target temperature" combination.
Turn the controller off and on again briefly to be able to read the version number.
The input mode can be changed on a user-specific basis in the configuration in
support of the process specification. To change the input mode, see
"Configuration"
The mode configured can be seen during program input in a segment, e.g. "time
1", as follows:
For "time and set temperature" input, only °C/°F or the time h is displayed as the
input unit. For gradient input, °C/°F and h appear together in the display as the
unit. The maximum gradient is 6000°C (fast heating)

Setting and Displaying the Date/Time
The P 330 has a real time clock that is set at the factory. The time of day can be
key. If the time of day is displayed incorrectly, the
displayed by pressing the
clock can be set as follows: The clock is set using a numerical combination of the
day of the week and the time. The setting of the day of the week corresponds to
the first digit of the numerical combination. Each day of the week has its own
number.
1=Mon, 2=Tue, 3=Wed, 4=Thu, 5=Fri, 6=Sat, 7=Sun.
Entry of the time of day must then be carried out with the last four digits of the
combination using a 24-hour clock:
E.g. 0735 for 7:35 AM, 1700 for 5:00 PM, etc.
Example: Setting the time "Wednesday (day 3), 7:35 AM"
Fig. 23: Example of setting the clock
The day and time are saved by pressing the

time with the symbol key
This clock is a real-time clock, that is, even when the controller is turned off, the
time is retained using a built-in battery. The lifetime of the battery is about 3 years.
When the battery is replaced, the saved data (set time) is lost. For the battery type,
see the chapter "Technical data".
The time can only be entered and displayed in 24-hour mode, that is, a display of
12:00 AM/PM is not possible. After the time is set, the controller is fully ready for
operation.

7.10 Brief Program Interruption
To interrupt program execution only temporarily, for instance to open the furnace
door for removal or addition of material, press the "pause"
key. Unlike the
"start/stop" key
the heating is still turned off, but the program is not reset
(regulation data is retained). The program is continued with the "start/stop" key
in the last active segment, taking the elapsed time in that segment into
account.
If the furnace door is opened without the pause function, the controller immediately
reacts to the temperature drop and starts to heat immediately after the door is shut
– the result can be an overcompensation in the furnace chamber temperature (see
also "Safety" in the furnace operating instructions).

If the program is in a ramp, the
key sets the corresponding ramp time (e.g.
"time 1" or "time 3") to zero, so that the controller attempts to reach segment
temperature "T" as quickly as possible using maximum power and maximum
gradients. After the segment temperature is reached, the segment advances.
Segment skip in the holding time
If the "Segment skip" key is pressed during a holding time (e.g. "time 2" or "time
4"), then the holding time is ended immediately and the controller jumps directly
into the next segment.

8.5
Auto Tune
The regulation parameters of the controller are already set at the factory for the
optimum regulation of the furnace. If the regulation behavior is still not sufficient for
your process, the regulation behavior can be improved using auto tune.
The controller has four different parameter sets which are already configured for
different furnace models. The configured parameter set can be seen in parameter
"PA" (see also Configuration). When performing auto tune, the regulation
parameters of the selected parameter set are determined and stored using a
special measurement procedure.
Start the auto tune process only with a cooled furnace (T < 60°C), since otherwise
incorrect parameters will be determined for the regulation segment. On the
program input level first enter a value for "T1" at which the temperature is to be
optimized. Set all times "time" to "00:00"n.
In configuration level 2, select parameter "tu", set it to "1", and confirm with the
key. This will start the auto tune and "tune" will alternate with the furnace
temperature in the display. Once the optimization is complete, the status field "end"
will show in the display. The parameters determined are stored by the controller
into the parameter set for the corresponding temperature range.
Auto tune is always performed at about 70% of the value set in "T1" in any case, to
avoid destruction of the furnace, for instance when optimizing the maximum
temperature. Auto tune may take more than 3 hours for some models, depending
on the furnace type and temperature range. The regulation behavior may be
degraded in other temperature ranges after an auto tune! Wieland assumes no
liability for damage caused by manual or automatic changes to the regulation
parameters (see also Temperature-dependent parameter sets).
Note
Perform an auto tune, if necessary, for all temperature ranges.

Furnace loading
Swivel the furnace door carefully away upwards.
Only materials with known characteristics and melting temperatures may be used.
Observe the material safety data sheets if necessary.
When loading the furnace, ensure that the door collar and the heating elements are
not damaged. Under all circumstances, avoid coming into contact with the heating
elements when loading the furnace; this may lead to the immediate destruction of
the heating elements.
If possible, the load must be positioned centrally in the working chamber on the
ceramic insert plate. This guarantees even heating.
If a large quantity of material is placed into the furnace chamber, the heating time
may increase significantly.
If a crucible is used, make sure that the material to be melted is inserted carefully
into the crucible. Crucibles are sensitive to shocks and impact. Metals expand
more quickly and strongly than the crucible when heated. Be sure that the
recommendations of the crucible manufacturer for maintenance and handling are
carefully observed.
After loading, the furnace door must be closed carefully. The furnace door should
be closed gently in order not to damage the insulation. Make sure that the door is
closed correctly.
If possible, the furnace must not be opened when hot. If it has to be opened at a
high temperature, this should take place as briefly as possible. Attention must be
paid to adequate protective clothing and room ventilation, see chapter "Safety".
The stainless steel sheet may become discolored (particularly on opening when
hot), but this does not impair the function of the furnace.
Additional care measures
Ensure that objects like teapots, bottles, and similar items are kept away from the
furnace.
Warning - danger due to electrical current!
To protect the operator and the furnace, the heating program must always be
stopped when the furnace is being loaded. There is a risk of electric shock on
noncompliance.

Cleaning, lubrication, and maintenance tasks may only be performed by authorized
experts following the maintenance instructions and accident protection guidelines.
We recommend that maintenance and repair be performed by Wieland GmbH
Service. Failure to comply runs the risk of bodily injury, death, or significant
property damage!
Warning - danger due to electrical current!
Work on the electrical equipment may only be performed by qualified, authorized
electricians!
During maintenance work, the voltage supply to the furnace and/or switching
system must be switched off to prevent unintentional commissioning. Disconnect
the mains power connector due to reasons of safety.
Operators may only correct malfunctions which are obviously due to operational
error!
Wait until the furnace chamber and attaching parts have cooled to room
temperature.
The furnace must be visually inspected at regular intervals for damage. The interior
of the furnace must also be cleaned as required (e.g. vacuuming out) Attention:
Do not bang against the heating elements to avoid breaking them.
While work is being performed on the furnace, the furnace and work room must
additionally be ventilated with fresh air.
Safety systems removed during maintenance tasks must be replaced after the
work.
Warning of swinging loads in the workshop (e.g. crane systems). Work under a
lifted load (e.g. a lifted furnace or switching system) is not permitted.
Safety switches and any limit switches present must be checked for function
periodically (BGV A3) or according to the national guidelines of the country of
operation.
To ensure proper temperature regulation of the furnace, the thermocouple must be
checked for damage before every process.
If necessary, retighten the element holders (see chapter "Replacing the Heating
Element"). Before carrying out this work, the voltage supply to the furnace and/or
switching system must be switched off (disconnect mains power connector). The
regulations (BGV A3) or corresponding national regulations in the relevant country
of operation must be observed.
There are one or more contactors in the control system. The contacts of these
circuit breakers are wearing parts and must therefore be serviced and/or replaced
regularly (BGV A3) or according to the national guidelines of the country of
operation.
The switching system cabinet (if available) contains vent grilles with integrated filter
mats. These must be cleaned and/or replaced at regular intervals in order to
ensure sufficient intake and outflow of air from the switching system. During
melting operation, the switching cabinet door must always be firmly closed.

This furnace contains ceramic fiber material in the insulation.
Active handling of these fibers (e.g., exchange of the insulation) in the Federal
Republic of Germany is subject to the conditions of the Ordinance on Hazardous
Substances, Annex V, No. 7 ("Artificial mineral fibers") of June 12, 1998. In the rest
of the European Union, ceramic fibers are categorized as follows by Directive
97/69/EC of the Commission of December 5, 1997 CARC. Cat. 2; R 49; Xi R 38.
Work with the fiber insulation must therefore be done in such a way that as little
fiber dust as possible is released.
The following points must be noted when handling ceramic fiber:
- Dust development during processing should be minimized.
- Contact with skin and eyes should be avoided. The effects caused by
fibers on the skin or in the eyes may cause mechanical irritation, as a result of
which reddening and itching may occur.
- When processing large quantities of ceramic fibers, loose work clothing with
long sleeves, gloves and safety glasses should be worn.
- When working with ceramic fiber insulation inside furnaces, a half/quarter mask
with P2 filter should additionally be worn.
The furnace and its operating equipment must be regularly checked in accordance
with the regulations of the employer's liability insurance association (BGV A3) or
the corresponding national regulations in the relevant country of use!

prevent serious injury, damage to property, and damage to the environment.
The oven may only be shut down by authorized, trained personnel.
The following operating materials/parts are to be disposed of by:
_________________________________________________________________
_________________________________________________________________
_________________________________________________________________
_________________________________________________________________
Oils and other substances that are hazardous to water must be completely
removed before the oven is dismantled for reuse or scrap.
Ensure that operating materials, lubricants, and consumables are disposed of in an
environmentally compliant manner. Regulations relating to proper waste recycling
and disposal must be observed.
The oven may be lifted only at the intended points.

15.1 Transportation/Return Transportation
If you still have the original packaging, this is the safest way to send an oven.
Otherwise:
Choose suitable, adequately sturdy packaging. During transportation, packages
are often stacked, bumped, or dropped; the packaging acts as external protection
for your oven.
+45
-5°C
- Drain all piping and containers before transportation/return transportation
(e.g. cooling water). Pump off operating materials and dispose of properly.
- Do not subject the oven to extreme cold or hot temperatures (direct
sunlight).
Storage temperature -5°C to 45 ° (-23°F to 113°F)
Humidity 5% to 80%, non condensing
- Place the oven on a level floor to prevent distortion.
- Packaging and transportation may be carried out only by qualified and
authorized persons
If your oven has transportation securing equipment (see "Transportation Securing
Equipment"), use this.
Otherwise, in general:
"Fix" and "secure" (adhesive tape) all moving parts and cushion and protect any
projecting parts against breakage.
Protect your electronic equipment against moisture and make sure that no loose
packaging material can get inside it.
Fill gaps in your packaging with soft but adequately firm material (e.g. foam mats)
and make sure that the equipment cannot slide around in the packaging.
If the goods are damaged during return transportation due to inadequate
packaging or some other breach of duty, the costs will be borne by the
customer.
As a rule:
The oven is sent without accessories, unless the technician expressly requests
them.
Enclose a detailed description of the fault along with the oven – this saves the
technician time and costs.
Don't forget to enclose the name and phone number of a contact in case there are
any questions.
Note
Return transportation may only be carried out according to the information given on
the packaging or in the transportation documents.
Note
Transportation and return transportation not covered by a warranty claim are paid
for by the customer.
