Page 6: Euroflec: Total Nofrost
1.2. EUROFLEC: total nofrost The EUROFLEC 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 fan circulates the air. 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. -

Page 16: Foamed Connectors Seat
Inside the freezer compartment, behind the panel of the evaporator battery, there are the foamed connectors where the NTC sensors (A), the defrosting heaters (B), the evaporator fan (C) and the freezer door switch (D) must be connected. EUROFLEC 16/36... -
Page 17: Fans
As the freezer compartment is cooled only by the cold air ducted in by the evaporator fan, after 30 minutes the fan switches on, even if the compressor is still switched off, while the condenser fan is off till the compressor starts again. Compressor Condenser fan Evaporator fan EUROFLEC 17/36... -
Page 18: Operation With Door Opened And Compressor Switched On
If one of the two doors is opened while the compressor is switched off, in the span of 30 minutes during which also the fans are switched off, the evaporator fan is activated for 2 minutes after the door closes. After 2 minutes, the evaporator fan switches off automatically. Compressor Condenser fan Evaporator fan Doors EUROFLEC 18/36... -

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 EUROFLEC range of fridge- freezers. -
Page 22: Control Panel
In order to ensure that the circuit does not remain pressurised, 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. EUROFLEC 22/36... -
