Please read this user manual carefully before using the device
and keep it for future reference.
Following the manual's recommendations guarantees long-lasting and
failure-free exploitation of the device.
IT IS FORBIDDEN
1. Make repairs on your own and fail to comply with the rules contained in
this manual regarding the connection and operation of the device;
2. Store substances that may explode in the device, such as aerosols
filled with combustible propellants;
3. Place the device in the sun;
4. Covering the inlet and outlet of air from the aggregate;
5. Switching the device on to the mains without a properly
functioning protective circuit system;
6. Use of extension cords and dividers to connect power.
7. Use devices/objects that could cause an electric spark inside
the device and in the aggregate chamber.
WARNING!
1. Incorrect connecting of the device to the mains may result in an
electric shock.
2. In the event of sparks or breakdowns, immediately disconnect the
device from the power supply by pulling the plug from the socket and
calling an authorized service technician.
3. It is necessary to protect the wiring system and control system
against water and mechanical damage.
4. When servicing and replacing parts, the device must be
disconnected from the power supply
CAUTION!
1. Before cleaning the condenser – switch the device off!
2. When cleaning the condenser, do not use tools/objects that could
cause an electric spark.
3. Water condensation on glass panes and sheets at high relative
humidity (over 60%) is a natural phenomenon. Long-term and frequent
occurrence of dewing indicates inadequate ambient conditions and is
not a basis for calling the service!
4. Take care when removing the glass panes.
Breaking the glass panes can cause injury!
iThe device is not intended for household use.
The device is not intended for outdoor use.

4. WIRING SYSTEM
1. The device is equipped with the protective PE cable.
2. Before connecting the device to the power supply, check the compatibility of the mains
voltage with the device supplying voltage (data on the plate).
3. Connecting the device to the mains socket should be made so that the plug of the
connecting cable is visible and easily accessible for the service.
4. The device should be connected to a separate, properly made electrical circuit protected
by a fuse no greater than 10 A with a B-characteristic, ended with a socket with a protective
pin.
5. The device may be started only after confirming the effectiveness of the shock protection
with the results of measurements carried out in accordance with the applicable regulations.
6. Before carrying out any maintenance or cleaning, turn off the device with the switch and
then remove the plug from the mains socket.
7. The device is started after connecting the plug to the mains socket, and then by turning
on the switch. The backlight of the switch indicates that the device has been turned on.
8. Any repair of electrical installation and replacement of the connection cable (only into
original one available from the manufacturer) may be carried out by an authorized
electrician only.

7. POSITIONING, START-UP AND OPERATION
To ensure proper operation, the device should be placed in an area with a good air circulation,
away from heat sources and sunlight, free from dust (the device is not dustproof), at ambient
temperature from +16°C to +25°C – 3rd climatic class. The manufacturer is not responsible
for interferences of the device operation in temperature beyond given range for 3rd climatic class.
Place the device horizontally and connect it to the power supply according to the guidelines
included in the chapter No. 4 - “Wiring system”.
WARNING:
The device cannot be placed below the floor level (in a hollow).
The room in which the device is located must have a minimum cubature of 4 m3.
Start-up and exploitation:
The aggregate is switched on and off by means of the switch shown on picture in the chapter No. 6.
The temperature inside the device is adjusted by means of the electronic temperature controller,
according to the instructions included in the chapter No. 10.
After switching the device on, leave it empty until its switching off for the first time. After that it is
ready to be filled with products.
Maximum load that might be put in the exposition – 110 kg (the load has to be distributed evenly on
the whole surface of the top).
8. MAINTENANCE
After disconnecting the device from power supply, the general maintenance should be done
by the user, as follows:
1. washing with water of the temperature not more than +40°C with addition of natural cleaning
agents. To wash and clean the device it is forbidden to use agents containing of chlorine
and sodium of various varieties, which destroy the protective layer and components
of the device! Any residual glue or silicone on the metal parts of the device should be removed
only with gasoline (not applicable to plastic components!).
Do not use other organic solvents.
2. removing impurities from the condenser by means of vacuum cleaner (from up to down -
along the fins) at least once a month so that the flow of the cooling air through the condenser
fins is not hampered.
Not following the above instructions causes increased energy consumption, decreased
refrigeration efficiency of the device and eventually result in aggregate overheating,
which consequently may lead to failure.
While cleaning the condenser be careful not to deform the fins. Do not wash the device
with a water jet. It is not advisable to clean the condenser with a brush as it causes
impurities penetration deep into the condenser fins and finally block the air flow
completely.
For units with an automatic condensation evaporation system, clean the container (fig. 1) every 2
weeks to prevent the formation of unpleasant odours.

9. TRANSPORT AND EQUIPMENT
While transporting secure the device to prevent its overturning, damage of the
paint coat and breaking of the glass elements. When handling the device do not
press the glass elements, do not grab the door or aggregate protective crate to
lift the device. It is best to use belts and place them under the frame, between
the feet (so that the belts do not slide). Do not lift the device directly with a
forklift or a pallet truck without a palette, as it may damage the aggregate.
10. TEMPERATURE CONTROLLER MANUAL
DISPLAY DESCRIPTION
The display is three digits with decimal point and 6 symbols (compressor, fan,
defrost, AUX, alarm and clock).
1. COMPRESSOR
The symbol is visible when the compressor operates. It flashes when the
compressor’s start up is delayed because of protective procedure. It flashes in the
cycle: two flashes – break when there is continuous operation mode activated.
2. FAN
The symbol is visible when there are evaporator fans switched on. It flashes when
the fans start-up is delayed by means of external switching off or when there
is other procedure in progress.
3. DEFROST
The symbol is visible when there is defrost function switched on. It flashes when
the defrost start-up is delayed by means of external switching off or when there is
other procedure in progress.
4. AUX
The symbol is visible when there is additional AUX output activated.
5. CLOCK
The symbol is visible when there is clock switched on – switching on by means of
„tEn” switch or when there is time limit set. When switching on the symbols
appears for few seconds as clock function availability.
6. ALARM
The symbol is visible when there is alarm activated.
