4 DOOR REFRIGERATOR WITH R600a 5/22
1. Presentation
The four-door refrigerator consists of three sections which are specially designed to conserve the various types
of food in the best possible way.
Refrigerator compartment ("A"): air circulation by natural convection makes it possible to maintain the
compartment at the ideal temperature and humidity for conservation of fresh foods.
The temperature is controlled by an adjustable thermostat positioned on the control panel.
Zero degrees compartment ("B"): the temperature in this compartment is maintained constant at between 0°C
and +3°C. The compartment is cooled by the circulation of forced air from the freezer compartment below.
The temperature is controlled by a flap-operated thermostat which opens and closes the air duct between the
refrigerator and the freezer.
Freezer compartment ("C"): The cold is produced by a battery evaporator; forced circulation of the air is provided
by a fan. In this way, the humid air inside the compartment is deposited in the form of ice on the battery, and not
on the packets of food.
Periodically (at intervals of 12 hours), the timer switches on the defrosting heating element in order to melt any
ice that has accumulated on the battery. The duration of the defrosting cycle is approximately 11 minutes.
When the temperature of the battery r10°C, the end-of-defrosting thermal cut-out switches off the
heating element. If this switch should malfunction, a second thermal cut-out intervenes as soon as the
temperature r40°C.
An electronic thermometer with a LED display shows the temperature inside the compartment.
The temperature is controlled by an adjustable thermostat positioned on the control panel.
The appliance is fitted with two separate cooling circuits:
1. refrigerator circuit;
2. zero degrees - freezer compartment circuit.
