Page 10: Operation
5. OPERATION 5.1 NORMAL When the thermostat knob is on (OFF) position it means that: the compressor is off; all Leds are off; the electronic board is powered ( 220-240V 50Hz ! ! ! ). Warning: the electronic board is powered with a 220-240V 50Hz voltage even if the thermostat knob is on (OFF) position. -
Page 11: Normal With First Switching On Or Power Failure
5.2 NORMAL WITH FIRST SWITCHING ON OR POWER FAILURE In case of fault when the appliance is switched on for the first time or in case of a power failure, one of the two conditions described below occurs: 1. If the internal temperature is higher or the same as the cut-in temperature of the thermostat (CUT-IN), when the power is restored, the electronic board activates the compressor and the fan till the set temperature is reached and after 5 hours the electronic board activates the defrosting procedure. -
Page 12: Defrosting
5.3 DEFROSTING All the humidity in the compartment accumulates on the evaporator, which is the coldest part of the compartment; periodically, every about 14 hours minimum with normal door openings (till 71 hours if the door is never opened!), it is necessary to defrost the ice which forms on the battery, therefore, the electronic board disconnect the circuit which powers the compressor (3) and the fan (24) and, after checking for the defrosting heater, it powers the defrosting heater (9 e 9a) for about 20 minutes minimum. -
