4. Defrosting.
● Periodically, the system will automatically pass the stages of defrosting. This is necessary
to prevent ice formation on the evaporator which reduces the cooling efficiency. When
defrosting, the compressor stops working and the temperature slightly rises inside the
cabinet. The defrosting process takes 25 minutes, then the compressor switches to normal
operation.
● In some rare cases, defrosting can be performed because of high climate humidity, frequent
opening of doors, placing of wet products in the cabinet or too low operating temperature.
A significant increase in the formation of ice reduces the efficiency of the cabinet and
requires third-party intervention in the defrosting process. To do this, press the buttons
and
at the same time, and hold them for 6 seconds till the defrosting indicator
lights up.
5. Cleaning.
a) disconnect the equipment from the power source;
b) wipe the internal surfaces with wet cloth using neutral cleaning agents.
NEVER wipe the control panel, power cables and connectors, they must always be dry!
NEVER use steel or sharp tools!
c) wipe all surfaces completely dry;
d) to ensure long-term and reliable operation of the equipment, the evaporator must be
cleaned every three months preferably by a vacuum hose. The evaporator is located behind
the lower grid. In case of increased dust content, the evaporator should be cleaned at
shorter intervals.
e) all the sealing elements should be washed with slightly soapy water.
6. Lamp replacement.
a) switch off the power
b) undo the screws on both sides of the bowl shade, take it off, disconnect the wires and
remove the lamp.
c) screw a new lamp, connect the wires, install and screw the bowl shade.
