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.
