3.0 Description of the appliance
ICN 3056/3066 from -20
The ICN 3056/3066 appliances are combined fridge-freezers for integrated use with a foamed-in refrigerator compartment rear wall evaporator and a NoFrost freezer compartment. The appliances are prepared for installation with a door-on-door system and are equipped with a soft stop function.
The temperature in the refrigerator compartment is controlled by an air sensor and an evaporator sensor.
The temperature in the freezer compartment is controlled by an air sensor and an evaporator sensor.
The refrigerator and freezer compartment evaporators are activated via a bi-stable solenoid valve. The two evaporators are connected in series (see schematic diagram 4.2.4). Therefore the refrigerator compartment can be operated only in conjunction with the freezer compartment. However, it is possible to operate the freezer compartment on its own.

Audible:
During start-up: During start-up the temperature display flashes until switch-off value has been reached, the audible alarm is
deactivated.
(e.g. With a set value of -18°C, a temperature of –14°C must be present for at least 20 minutes, then a temperature alarm is raised).
When the defrosting phase begins, the temperature alarm is suppressed for
1.5
hrs.
The defrosting phase is started:
- During start-up after 10 hours cumulative compressor running time.
- After a cumulative compressor running time of 10 to 60 hours maximum,
depending on the number/duration of the door openings.
When the defrosting phase begins, the compressor and the fan are switched off and the defrost heater is switched on.
The defrost heater remains switched on until
- the freezer compartment evaporator sensor has reached +7°C or
- a max. defrosting time of 40 minutes has been reached.
After the end of the heating phase, the compressor is switched on with a 5 minute delay.
If the SuperFrost function is activated during the defrosting phase, this will not interrupt defrosting.
When: After the door has been open for 60 seconds.
SuperFrost:
SuperFrost activated:
Cooling of freezer compartment to -39°C (quantity-controlled, 30 - 65 hours).
The appliance sets itself for at least 30 hours to -39°C. In the following
35 hours, after -39°C has been reached or a total time of 65 hours has elapsed,
SuperFrost ends automatically.
SuperFrost deactivated:
The freezer compartment sets itself to the set value.
