Ambient temperature and ventilation
Ambient temperature
The appliance is designed for a specific climate class. Depending on the climate class, the appliance can be operated at the following temperatures.
The climate class can be found on the rating plate. Fig. 13
| Climate class Permitted ambient temperature |
| SN +10 °C to 32 °C |
| N +16 °C to 32 °C |
| ST +16 °C to 38 °C |
| T +16 °C to 43 °C |
Note
The appliance is fully functional within the room temperature limits of the indicated climatic class. If an appliance of climatic class SN is operated at colder room temperatures, the appliance will not be damaged up to a temperature of +5 °C.
Ventilation
The air on the rear panel of the appliance heats up. Conduction of the heated air must not be obstructed. Otherwise, the refrigeration unit must work harder. This increases power consumption.
Therefore: Never cover or block the ventilation openings!
Installation location
Install the appliance in a dry, well ventilated room. The installation location should neither be exposed to direct sunlight nor near a heat source, e.g. a cooker, radiator, etc. If installation next to a heat source is unavoidable, use a suitable insulating plate or observe the following minimum distances to a heat source:
■ 3 cm to electric or gas cookers.
■ 30 cm to an oil or coal-fired cooker.
Connecting the appliance
After installing the appliance, wait at least 1 hour until the appliance is switched on. During transportation the oil in the compressor may have flowed into the refrigeration system.
Before switching on the appliance for the first time, clean the interior of the appliance (see chapter “Cleaning the appliance”).
Electrical connection
The socket must be near the appliance and also freely accessible following installation of the appliance.
The appliance complies with the protection class I. Connect the appliance to 220-240 V/50 Hz alternating current via a correctly installed socket with protective conductor. The socket must be fused with a 10 to 16 A fuse.
For appliances operated in non-European countries, check whether the stated voltage and current type match the values of your mains supply match the values of the mains supply. This information can be found on the rating plate. Fig. 13

Warning
Never connect the appliance to electronic energy saver plugs.
Our appliances can be used with mains and sine-controlled inverters. Mains-controlled inverters are used for photovoltaic systems which are connected directly to the national grid.

Usable capacity
Information on the usable capacity can be found inside your appliance on the rating plate. Fig. 13
Refrigerator compartment
The refrigerator compartment is the ideal storage location for ready meals, cakes and pastries, preserved food, condensed milk, hard cheese, fruit and vegetables sensitive to cold as well as tropical fruit.
Note when loading products
Wrap or cover food before placing in the appliance. This will retain the aroma, colour and freshness of the food. In addition, flavours will not be transferred between foods and the plastic parts will not become discoloured.
Note
Avoid contact between food and rear panel. Otherwise the air circulation will be impaired.
Food or packaging could freeze to the rear panel.
Note the chill zones in the refrigerator compartment
The air circulation in the refrigerator compartment creates different chill zones:
- Coldest zone is between the arrow stamped on the side and the glass shelf situated below. Fig. 3
Note
Store perishable food (e.g. fish, sausage, meat) in the coldest zones.
■ Warmest zone is at the very top of the door.
Note
Store e.g. cheese and butter in the warmest zone. When served, the cheese will not have lost its flavour and the butter will be easy to spread.
Super cooling
Super cooling sets the refrigerator temperature to the coldest temperature setting for approx. 6 hours. Then the appliance automatically switches to the temperature set prior to super cooling mode.
Switch on super cooling mode, e.g.
■ before placing large quantities of food in the refrigerator compartment.
■ for the fast cooling of drinks.
