3.0 Description of the appliance

The IKP ..50 are refrigerators for integrated use with a freely suspended rear wall evaporator.
The IKP ..54 are refrigerators for integrated use with a foamed-in rear wall evaporator and a 4-star freezer
compartment. The appliances are prepared for installation with a door-on-door system and are equipped with a
soft stop function. Due to its size, the IKP 2850 as the only IKP appliance has a fan for uniform temperature
distribution.
The temperature is controlled by an air sensor and an evaporator sensor.

4.0 Control and functional components

4.1 Refrigerator compartment

Electr. control system:

Series 6 electronic control system: integral PCB.

Setting range:

+2°C to +9°C

Display range:

2°C to 50°C

Door alarm:

No

Interior light:

Position: Inside right.
Function: - Is switched on as soon as refrigerator compartment door is

opened.

- Is switched off after door has been open for 15 minutes.

Attention: 230V applied to the LEDs.

Reed PCB:

Position: In front panel.
Function: Switches the interior light on when the door is opened.

Only IKP 2850:
Turns off the fan (if activated) when the door is opened.

Air sensor:

Position: In light housing.
Function: - Switches the compressor off.

Evaporator sensor: Position: In IKP ..50: In the sensor pocket on the rear of the evaporator.

In IKP ..54: In sensor holder on compartment liner rear wall.
Function: Switches compressor on.

SuperCool:

With SuperCool the appliance switches to the coldest control setting for 6 hours.

In IKP ..54: The freezer compartment becomes correspondingly colder.

Defrosting:

Automatic during standstill phase of the compressor.

Fan:

(Only IKP 2850)

Position: At the centre back of the ceiling of the compartment liner.
Function: ON: - Fan switch ON and

- Compressor ON and

- Refrigerator compartment door closed
OFF: - Fan switch OFF or

- Compressor OFF or

- Refrigerator compartment door open

During start-up the fan is activated only from an evaporator sensor
temperature of +8°C and colder.

Compressor: Function: ON: - Refrigerator compartment evaporator sensor switch-on

value
Note: On-delay time (8 mins.) must have elapsed.

OFF: - Refrigerator compartment air sensor switch-off value
