2.1.
Refrigerating system
The device is equipped with a single-stage compressor refrigeration circuit controlled by an electronic
temperature controller with an automatic defrosting system - defrosting takes place every 4–6 hours.
The cooling installation is filled with natural refrigerant R290.
The system does not require any maintenance operations except for periodical cleaning of the
condenser.
Compressor
The compressor is equipped with an internal redundant (thermal) switch that protects the motor aga-
inst accidental overloads.
In the case of unnatural, noisy work or difficult start of the compressor, turn the device off, check the
condition of the condenser (in case it is dirty, clean it). If the compressor is hot – wait for it to cool and
re-start.
2.2.
Electrical installation and power supply
The power supply should be made from a low voltage circuit (230V / 50Hz) terminated with a socket
equipped with a protective (grounding) pin.
It is unacceptable to use a device connected to a socket not equipped with a protective conductor.
The installation should be made in accordance with current standards, it should be protected by
a residual current circuit breaker and an overcurrent switch adapted to the electric power of the device
Do not connect the device to mains using extension cords.
The electrical installation should be made by a qualified electrician.
If the power cord is damaged, it should be replaced by the manufacturer or by a specialist repair facility
or by a qualified person in order to avoid a hazard.
An improperly made electrical installation may lead to electric shock or fire.
