    Electronic control (electronic board ERF2050) LCD display (liquid crystal digit) They are appliances (KBIN 260 IT SD) with the following PNCs: MODEL BRAND 92569770000 ERF2620 Electrolux 92569770100 ERF2620 Electrolux 92569770200 ZI918/9FFA Zanussi The controls of the appliance are inserted in the higher part of the cooler compartment.
  • Page 6 The appliance consists of the following compartments: freezer; cooler; The evaporating system consists of: battery cold module (freezer compartment); Key: A = control panel B = cooler compartment C = cold module D = freezer compartment TOTAL NO FROST FIFTY SLIDING DOOR 6/39...
  • Page 7 The temperature detection of the cooler compartment is carried out by 1 sensor: cooler temperature sensor (located inside the air vent grid) The temperature detection of the freezer compartment is carried out by 1 sensor: freezer temperature sensor (located inside the freezer cell) The defrosting of the battery evaporator is controlled by the electronic board through the temperature detection of the sensors and the detection of the door opening.

    2. AIR CIRCULATION Unlike in the PARTIAL NO FROST refrigerator, in the TOTAL type the cooler and the freezer communicate each other, therefore the battery evaporator cools both compartments. The cold produced by the battery evaporator in the freezer compartment is distributed by the F fan placed behind the cold module.

    5.1.e. Air flow regulator (damper) The temperature regulation of the cooler compartment occurs by means of the passage or not of cold air from the damper, which can have only 2 fixed positions, opened or closed. The air flow regulator (damper) 1 is located inside the lamp holder diffuser 2. The damper consists of a door and a stepping motor and it is connected to the electric wiring by means of a 4- pole connector.

  • Page 25: Operation

    6. OPERATION 6.1. Normal Warning: unplug the appliance before operating. In case of first switching on with a freezer compartment temperature higher then 10 °C, the appliance operates with a test cycle (for the factory) for a maximum time of about 1,5 hours. In this period do not check the correct functioning of the appliance, since the loads are activated only for internal check (compressor, fan, defrosting heater, damper).
  • Page 26: Defrosting

    6.2. Defrosting All the humidity in the compartment accumulates on the evaporator, which is the coldest part of the compart- ment; periodically, about every 14 hours with normal door opening (up to 72 hours if the doors never open!), it is then necessary to defrost the ice on the battery.
  • Page 27: Super Function (Rapid Freezing)

    6.5. Cooler compartment switching off The refrigerator compartment can be switched off by turning the temperature regulation knob to 0. The display shows OF. The air flow regulator (damper) is closed and the lamp remains off also if the door is open.
