5.3 Refrigerator compartment
The natural circulation of air in the refrigerator compartment
results in zones differing in temperature. It is coldest directly
above the vegetable drawers and at the rear wall. It is warmest
at the top front of the compartment and in the door.
5.3.1 Food refrigeration
Note
The energy consumption increases and the cooling perform-
ance decreases if the ventilation is inadequate.
u Always keep the air slits of the fan free.
u Store perishable food such as ready-to-serve dishes, meat
products and sausages in the coldest zone. Place butter
and preserves in the upper area and in the door (see Appli-
ance at a glance).
u Use recyclable plastic, metal, aluminium and glass
containers and cling film for wrapping.
u Always store liquids and food which is subject to odour or
taste transfer in closed containers or cover them.
u Foods which give off a large amount of ethylene gas and
delicate foods, such as fruit, vegetables, salad, should
always be stored separately or wrapped so as not to reduce
the storage life; e.g. do not store tomatoes together with
kiwis or cabbage.
u Use the front area of the refrigerator compartment floor only
for briefly putting down cooled products, e.g. when rear-
ranging and sorting. However do not leave cooled products
there otherwise they may be pushed back or tipped over
when the door is closed.
u Do not store food too close together to enable good air
circulation.
5.3.2 Setting the temperature
The temperature depends on the following factors:
- the frequency of opening the door
- the room temperature of the installation location
- the type, temperature and quantity of the food
The temperature can be set from 9 °C to 1 °C, the recom-
mended temperature is 5 °C.
An average temperature of about –18 °C is reached in the
freezer compartment.*
u For a higher temperature setting: press Up button Fig. 2 (3) .
u For a lower temperature setting: press Down button
Fig. 2 (4) .
w When the button is pressed the first time, the previously set
value is indicated, flashing, in the temperature display.
u To change the temperature in 1 °C steps: briefly press the
button.
u To change the temperature continuously: hold down the
button.
w The value is displayed flashing during the setting operation.
w The actual temperature is displayed about 5 s after the last
press of a button. The temperature slowly adjusts to the new
value.
5.3.3 SuperCool
With SuperCool you switch to the highest cooling
performance to reach lower cooling temperatures.
Use SuperCool, to rapidly cool large amounts of
food.
When SuperCool is activated, the fan* may run. The appliance

that the noise of the refrigeration unit may be temporarily
louder.
The SuperCool function uses slightly more energy.
