4.6 Connecting the appliance
NOTICE
Risk of damage to the electronic control system!
u Do not use stand-alone inverters (conversion of d.c. to a.c./
three-phase) or energy saving plugs.
WARNING
Fire and overheating hazard!
u Do not use extension cables or multiple socket outlets.
The type of current (alternating current) and voltage at the
installation site have to conform with the data on the type plate
(see Appliance at a glance).
The socket must be properly earthed and fused. The tripping
current for the fuse must be between 10 A and 16 A.
The socket must be easily accessible so that the appliance can
be quickly disconnected from the supply in an emergency. It
must be outside the area of the rear of the appliance.
u Check the electrical connection.
u Plug in the power plug.
4.7 Switching on the appliance
u Press On/Off button Fig. 3 (1) .

5.1 Door alarm
If the door is open for longer than 60 seconds, the
audible warning will sound.
The audible alarm is automatically silenced when
the door is closed.
5.1.1 Muting the door alarm
The audible alarm can be muted when the door is open. The
sound switch-off function is active as long as the door is left
open.
u Press alarm button Fig. 3 (6) .
w The door alarm is silenced.
5.2 Temperature alarm
The audible alarm sounds if the freezer temperature
is not cold enough.
The alarm button flashes at the same time.
The cause of the temperature being too high may be:
- warm fresh food was placed inside
- too much warm ambient air flowed in when rearranging and
removing food
- power failure for some time
- the appliance is faulty
The audible alarm is automatically silenced, the alarm button
Fig. 3 (6) goes out and the temperature display stops flashing
when the temperature is sufficiently cold again.
If the alarm status persists: (see Malfunction).
Note
Food may be spoilt if the temperature is not cold enough.
u Check the quality of the food. Do not consume spoiled food.
5.2.1 Muting the temperature alarm
The audible alarm can be muted. When the temperature is
sufficiently cold again, the alarm function is active again.
u Press alarm button Fig. 3 (6) .
w The audible alarm is silenced.
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
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 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.
u To safeguard bottles from tipping over: move the bottle
holder.
5.3.2 Setting the temperature
The temperature depends on the following factors:
- the door opening frequency
- the room temperature at the site where the appliance is
installed
- the type, temperature and quantity of frozen food
Temperature setting to be recommended: 5 °C
The temperature can be changed continuously. Once the 1 °C
setting is reached, it starts again with 9 °C.
u To access temperature adjustment: press the setting button
Fig. 3 (2) once.
w The LED of the current temperature flashes in the tempera-
ture display.
u Press the setting button Fig. 3 (2) the number of times
needed until the required temperature shines in the LED
display.
Note
u Long pressing of the setting button sets a slightly colder
value within a small temperature range (e.g.: between 5 °C
and 7 °C). The LED of the next lower temperature range
then shines in the temperature display.
