The evaporator batteries for the R134a version feature only one defrosting heater, while the evaporator batteries for the R600a version feature two defrosting heaters connected in parallel for safety reasons of the product. The thermal protections are connected in series to the defrosting heaters and are cabled together, therefore, they are not interchangeable singularly.
- Page 7 The NOFROST refrigerators consist of a refrigerator compartment A and a freezer compartment B. The cold produced by the battery-driven evaporator in the freezer compartment is then distributed through the refrigerator and freezer compartment by the fan located above the battery.
- Page 8 The thermostat bulb is located inside the flap and reacts both to the air temperature of the air coming out of nozzle 2, and to the air temperature inside the refrigerator compartment. The air returns to the air compartment through the foam duct at the bottom of the compartment, entering from nozzle 3 and leaving from nozzle 4.

5. OPERATION 5.1 NORMAL In NOFROST refrigerators, the humidity inside the compartments (freezer or refrigerator) accumulates on evaporator battery thanks to the air circulation, avoiding the formation of frost on food. During normal operation the cam of the timer closes contacts 3-4 thus powering the compressor and fan circuits. -
Page 15: Defrosting
5.2 DEFROSTING The ice on the battery must be removed regularly, therefore after about 14 hours of operating, the timer (25) switches from contact 3-4 to contact 3-2, disconnecting the compressor and the fan and switching on the stylus defrosting heater (9) and armoured (9a). For safety reasons and rules in the evaporator battery there are two defrosting heaters that are simultaneously powered, since they are connected in parallel. -
