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 al-

lowed 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 wa-

shing 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 compo-

nents 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.

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.

Device siphon.

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).

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.

2.2 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 re-

moving water is the siphon located under the device.

2. Power aggregate on / off switch.

3. Rack lighting switch on / off.

In order to start the device, turn on the power supply (button 2).

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 tem-

perature, 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.

ATTENTION! In the case of displaying the flashing message „OFF” alternately with the tempera-

ture value, start the device with the UP / ON OFF key - hold it for 3 seconds.
