3.0 Description of the appliance
The HC(S)/CS 2062 is a combined fridge-freezer with a freely suspended rear wall evaporator in the refrigerator compartment and a NoFrost freezer compartment with IceMaker.
The temperature in the refrigerator compartment is controlled by an air sensor and an evaporator sensor.
The temperature in the freezer compartment is likewise controlled by an air sensor.
The appliance has 2 compressors. Therefore the refrigerator compartment and freezer compartment have a separate refrigeration circuit and can be controlled separately.
The freezer compartment is equipped with a NoFrost rear wall evaporator module, fan module, air sensor and evaporator sensor. The defrosting phases are initiated by way of the electronic control system. taking compressor running time and door openings into account. There is an automatic IceMaker in the freezer compartment.

•
Compressor with 4 different speeds (1600 / 1900 / 3000 / 3600 rpm).
•
The inverter electronic control is fitted directly on the compressor. The inverter electronic control controls the compressor with a pulse-width modulated square-wave voltage.
•
For speed value input, the inverter electronic module receives a square wave frequency signal from the power PCB.
This frequency signal is output with 56, 71, 87,100 or 117 Hz, depending on the speed at which the compressor is to run.

During start-up: is reached,
4 beeps.
The temperature display flashes until the switch-off value the audible alarm is switched OFF.
(E.g. given a set value of 0°F (-18°C), a temperature of 7°F (-14°C) has to be present for at least 20 minutes, then a temperature alarm is activated.)
When the defrosting phase begins, the temperature alarm is suppressed for
1.5 hrs.
The defrosting phase is initiated:
- During start-up after 6 hours cumulative compressor running time.
- After a cumulative compressor running time of 12 to 40 hours maximum, depending on the number/duration of the door openings.
As the defrosting phase begins, the compressor and fan are switched OFF and the defrost heater is switched ON.
The defrost heater remains switched ON until such time as
- the freezer compartment evaporator sensor has reached 41°F (+5°C) or
- a max. defrosting time of 50 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:
Audible:
If door is open, after 60 seconds.
3 beeps.
SuperFrost ON:
The appliance sets itself to -29°F (-34°C) for at least 30 hours. In the following 35 hours SuperFrost ends automatically once the temperature falls 8K below the set value (at 0°F (-18°C) -> -15°F (-26°C)) or after the total time of 65 hours has elapsed.
SuperFrost OFF:
The freezer compartment sets itself to the set value.
Attention:
If SuperFrost is actuated during a defrosting phase, the SuperFrost function is not performed before the defrosting phase has run.

5.3.9 Fitting the cover
Cover:
- The air guide channels have to be free from cables.
- Therefore put away the cables for the air sensor and reed PCB in the storage space above the evaporator.
- The cover has to butt fully against the compartment liner in order that proper air guidance is ensured.
- Pay attention that the cover also comes up against the ceiling of the compartment liner in order that the lower drawer can slide all the way in when it is closed.

Activation of the customer menu:
Push „
SuperFrost“ for 5 seconds.
All features and functions (e.g. child lock, brightness of the display,…) which can be activated and changed by the customer are described in the user’s manual.
Only the permanently activation of the FrenchDoor heater is not described in the user’s manual any more.
In case of heavy condensation on the FrenchDoor seal it is necessary to activae the heater permanently. Therefore for the state HI a new heater activation duration (HH) has to be programmed:
Push SuperFrost-symbol for 5 seconds -> customer menu gets activated
Push Down-symbol of the freezer compartment several times until H is shown in display
Push SuperFrost-symbol -> H0 is shown in display
Push Up-symbol for 4 seconds -> HH is shown in display
