Page 5: Introduction
The temperature inside the refrigerator compartment is controlled by a flap-operated mechanical thermostat. The Eurocombi range consists of eight models, with ALFA or DELTA stylings. All models are arched doors. The differences between the various models consist in the size of the refrigerator and freezer compartments and therefore in the number of shelves and drawers. - Page 6 Markets: UK, Spain, France, Germany, Italy, Sweden, Norway, Finland, Est Europe.

1.2. Eurocombi: total no-frost The Eurocombi is a total no-frost appliance, and as such its operation is based exclusively on the battery evaporator in the freezer compartment, which cools the air; the air is circulated by the fan. A duct embedded in foam channels the cold air into the refrigerator compartment, where the flap-operated mechanical thermostat regulates the flow of cold air and thus the temperature inside the refrigerator compartment. -

NTC switches the compressor on again when the temperature falls to below 65°C, thus keeping the fans in operation. 3.2.3. Connection box The connection box is located inside the freezer compartment. The NTC sensors, heaters, evaporator fan and freezer door switch are connected to the connection box. Eurocombi 14/32... -
Page 15: Fans
As the refrigerator compartment is cooled only by the cold air ducted in by the evaporator fan, the fans switch on again after 30 minutes even if the compressor remains off. compressor fans Eurocombi 15/32... -
Page 16: Door Aperture With Compressor
If one of the doors is opened while the compressor is not in operation, during the period of 30 minutes in which the fans are switched off, the fans will switch on again for two minutes from the moment the door is closed. Thereafter, the fans switch off automatically. compressor fans doors Eurocombi 16/32... -

(in air) bulb reaches the cut-in temperature, the flap opens, thus allowing cold air to enter from the freezer compartment. When the temperature in the refrigerator compartment reaches the cut-out value, the flap re-closes and prevents further air from being ducted into the refrigerator compartment. Eurocombi 18/32... -

4 hours and an upper limit of 25 hours. In this way, the appliance adapts the duration of the normal operating cycle to the duration of the previous defrosting cycle: this is the concept of adaptivity which distinguishes the Eurocombi range of fridge-freezers. compressor... -
Page 20: Control Panel
In order to ensure that the circuit does not remain pressurized, the electronic system introduces a 5-minute delay in compressor start-up each time the appliance is switched on. If it is desired to override this delay, press the alarm buttons (b and c) simultaneously within 15 seconds after switching on the appliance. Eurocombi 20/32... -
