unscrew the feet of the device. Accurate horizontal positioning of the rack
prevents noisy operation and ensures proper water drainage during defrosting.
After setting up the device, you must provide access to the power cord plug.
It is not allowed to place the refrigeration device in the immediate vicinity
of the elements that emit large amounts of heat (radiators, air heaters, etc.)
Inside the chamber for storing food products, you must not use electrical
appliances of a different type than those recommended by the manufacturer.
Protect the refrigeration circuit against damage.
After unpacking and setting the device and before it is put into operation,
the first washing should be carried out. The water used for washing should not
exceed 40ºC with the addition of neutral cleaning agents. It is forbidden to
use agents containing chlorine and sodium of different varieties, these agents
can destroy the protective layer and components of the device!
When cleaning the device, you can not use a water jet. The device should be
washed using a damp cloth.
The device should be left at rest for at least 2 hours after the completed
installation before it is turned on (applies to devices with an internal
unit), then the oil level is leveled and it prevents problems with the start-
up of the refrigeration unit!
In devices with an internal unit special attention should be paid not to block
the inlet holes in the aggregate chamber (perforation in the lower part of the
rack), used for cooling the air of the unit. Accurate horizontal positioning
of the rack prevents noisy operation and ensures proper water drainage during
defrosting.
2.2 CONNECTION OF THE SEWING MACHINE.
During the cyclical defrosting process, the ice accumulated on the evaporator
of the device melts.
The water created as a result of the process must be removed from the device.
The place of removing water is the siphon located under the device.
Attention! Before carrying out any maintenance, turn off the cooling rack from the mains (disconnect the plug from the socket by holding the socket with the other hand).
In order to connect the device to the sewage system, appropriate sanitary elements should be fitted to the siphon installed in the device, which enables attaching it to the drain. After connecting the device to the sewerage network, check the connections for leaks.
2.3 STORAGE OF PRODUCTS IN THE DEVICE
Before brewing, run the empty device and leave it working until the desired
temperature is reached. Once it has been reached, you can start to load the
goods. When stacking goods on shelves, leave space between them to allow air
to circulate inside the device. Do not place non-refrigerated products in the
device. In the event of a power failure of the device, all products should be
emptied. If the device will not be used for a longer period of time,
disconnect it from the mains, empty, wash and leave the door ajar.
2.4 STARTING THE DEVICE.
After correct installation and leveling (see points 1.5 and 2.1 of the
manual), you can start the device.
Electric switches and a digital thermostat at the top of the front of the rack
are used to start and operate the device.

alternately with the temperature value, start the device with the UP / ON OFF
key – hold it for 3 seconds.
2.5 TEMPERATURE ADJUSTMENT
Attention! The temperature range of the device’s chamber and the operating
cycles of the condensing unit can fluctuate – this is related to many factors,
such as: ambient temperature, relative humidity, temperature of the products
put in and their number, etc.
To adjust the set temperature in the device, use a digital thermostat. The
operating parameters of the temperature controller necessary for the proper
functioning of the device are introduced at the production stage by the
manufacturer. The user should check the set temperature before the first
start-up of the device and change its value if necessary.

3.2 CONDENSER CLEANING (Version with internal unit)
Keeping the condenser clean is essential for the proper operation of the
refrigeration unit.
Contamination of the condenser causes a change in the heat exchange
characteristics, which increases the consumption of electricity, and the
compressor may also fail.
The condenser should be cleaned at least once every 2 months. If the condenser
gets faster, the processing process should be more often.
Contamination of the compressor on the condenser is dirty and as a result, an
emergency device, which is not a guarantee!
Attention! Before carrying out any maintenance, switch off the device from
the mains (disconnect the plug from the socket by holding it with the other
hand).
The device condenser is located at the bottom of the device. When cleaning the condensers, be especially careful !! .
Attention! Do not touch the condenser part directly. Failure to follow the
instructions may cause injury.
To remove impurities from the condenser, use a soft brush or brush. In the
case of heavy soiling it is advisable to use a vacuum cleaner / compressed air
to suck / bleed dirt located between the fins. It is not recommended to use
hard brushes for cleaning the condenser – this causes dirt to get in between
the blades and may result in a completely clogged condenser.
