3. Technical Features
The refrigerator is a ventilated system, the evaporator is in a separate insulated box on the top.
All the materials used in the manufacturing of this unit are guaranteed to be suitable for use
with perishable foods. The gases used in the refrigerators are R-134a; in the refrigerator for
frozen food maintenance is R-404a.
The refrigerating circuit is in compliance with the current normative.
4. Operation
The gas in the refrigerating circuit is first compressed, liquefied and then evaporated in the
ventilated evaporator, situated on the top of the container.
This cycle involves the absorption of heat from the air in the refrigerator compartment and is
then cooled. The heat produced is then dissipated to the outside environment by a condenser
unit located on the top of the refrigerator.
5. Control Unit
The refrigerator responds to commands from a "digital control unit" and a "main switch pilot
light" in the top panel of the refrigerator.
The "main switch pilot light" is for turning on the power supply.
The red pilot light comes on to indicate that the unit is connected to the main electricity and to
start work.
The red pilot light comes off to indicate that the unit is disconnected and doesn't work. The
"digital control unit" is for the regulation of all parameters to provide the correct working of the
refrigerator. Please consult all parameters in the attachment manual of the "digital control
unit".
This manual is part of the instruction manual and is very important in case of service.
Applied refrigerant belongs to non-flammable refrigerant.
