3.0 Description of the appliance
The CN(es) ..03 is a combined refrigerator-freezer with a NoFrost freezer compartment. The appliance has a
compressor. The refrigerator and freezer compartment evaporator is activated via a bi-stable solenoid valve.
Both evaporators are connected in series (see 3.3 Schematic diagram: Refrigerating circuit).
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.
3.1 Refrigerator compartment:
The refrigerator compartment is equipped with a foamed-in evaporator and an evaporator sensor. The sensor is
separately replaceable.
The evaporator sensor is responsible for switching off the refrigeration, sees to the defrosting of the refrigerator
compartment evaporator and switches the refrigeration on.
A fan is optionally activatable for even temperature distribution.
3.2 NoFrost freezer compartment
The freezer compartment is equipped with a NoFrost rear wall evaporator module, fan module, air sensor and
evaporator sensor. Both sensors are separately replaceable. The defrosting phases are initiated by way of the
electronic control system, taking compressor running time and door openings into account.

When: After the refrigerator compartment door has been open for 60 secs.
Audible: 3 beeps.
Position: Inside left.
Function: - Is switched on as soon as refrigerator compartment door is opened.
- Is switched off after door has been open for 15 minutes.
Position: In front panel.
Function:- Switches the interior light on when the door is opened.
- Switching contact for door alarm.

- Switches the fan (if activated) off when the door is opened.
Position: Behind cover, on rear wall, level with light housing.
Function:- Refrigerator compartment evaporator sensor or freezer compartment
air sensor switches the compressor ON.
- Refrigerator compartment evaporator sensor and freezer
compartment air sensor switch the compressor OFF.
- Switches solenoid valve to position A (refrigerator + freezer
compartment)
- Switches solenoid valve to position B when the switch-off valve is
reached (freezer compartment only)

Defrosting:
Compressor:
Position: At the centre back of t he ceiling of the compartment liner.
Function:ON: - Fan switch ON and
- compressor ON and
- refrigerator compartment door closed and
- solenoid valve at position A (refrigerator + freezer
compartment)
OFF: - Fan switch OFF or
- compressor OFF or
- refrigerator compartment door open or
- solenoid valve at position B (freezer compartment)
During start-up the fan is activated only from an evaporator sensor temperature of +12°C and colder.
Automatic during standstill phase of the compressor. Automatic when solenoid valve is set to position B (freezer compartment).
Function: ON: - Refrigerator compartment evaporator sensor switch-
on value or
- freezer compartment air sensor switch-on value.
Note: On-delay time (8 mins.) must have elapsed.
OFF: - Refrigerator compartment evaporator sensor switch off value and
- freezer compartment air sensor switch-off value
