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!

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). It is
forbidden to cover inlet and outlet of air from aggregate.
Place the device horizontally and connect it to the power supply according to the
guidelines included in the chapter No. 4 - “Wiring system”.
The manufacturer is not responsible for interferences of the device operation in
temperature below +16°C (too long defrosting cycle) and above +25°C (3rd climatic
class).
The order of operations before starting
Set the device in the desired place and screw all the feet to a slight resistance, then
using a spirit level by unscrewing the feet set the device horizontally.
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.
The sockets mounted on the device cannot be loaded with a current greater than
1.0 A (230 W) in total - regardless of the number of sockets installed and the
number of connected receivers.
Power cord is connected directly with sockets mounted on the device.
The aggregate and lighting switches do not disconnect current voltage into
the socket.
Start-up and exploitation:
The aggregate and lighting is switched on and off by means of the switch shown on
picture 1b.
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.
The goods on the shelves should be placed evenly so that they do not stick out
beyond the contours of the shelves - to maintain proper air circulation inside the
device.
Maximum shelf load: 15 kg / m².
In case of crackling coming from the condensate evaporation container, disconnect the
device from the power supply, wait for the heater to cool (approx. 10 min) and clean the
heater and container with a cloth.
Short-term condensation of water on glass panes and metal parts is a natural
phenomenon. Longlasting and frequent occurrence of condensation indicates
inappropriate environmental conditions (ambient humidity and temperature too
high).

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 condensate evaporation system, clean the container every
2 weeks to prevent the formation of unpleasant odours.
