Switching off
Disconnect the power supply to switch off the appli-
ance.
If the appliance is out of use for long periods:
Remove the appliance content.
Defrost (model dependent) and clean the device
thoroughly (see ”Cleaning and Maintenance”).
Leave open the appliance door to avoid formation
of mold and unpleased odor.
Tips for Energy saving
Disconnect the appliance from the power supply,
if it isn’t in use.
Do not install the appliance near stoves, heaters
or other heat sources. In case of higher ambient
temperatures, the compressor will run more fre-
quently and longer.
Ensure enough ventilation at the bottom and rear
side. Never block ventilation openings.
Place all shelves, racks or drawers (depending on
the model) in their original position.
Adjust the temperature not colder than necessary.
Allow warm food to cool before placing it in the
appliance.
Open the unit door only as necessary.
Defrost the unit regularly (model dependent).
The seal of the appliance door must be complete-
ly intact, so that the door closes properly.
Cleaning and Maintenance
WARNING:
Always disconnect the appliance from the power
supply before cleaning and user maintenance.
Do not use steam cleaners for cleaning the appli-
ance; moisture could enter electrical components.
Risk of electric shock! Hot steam could damage
the plastic parts.
The unit must be dry before restarting operation.
CAUTION:
Do not use a wire brush or other sharp, abrasive
items.
Do not use any acidic or abrasive detergents.
Do not damage the refrigerant circuit.
Cleaning the appliance including interior
Clean the appliance interior, the exterior surfaces,
the accessories and the door seal regularly with
warm water and mild detergent; or with a clean,
damp microfiber cloth without cleaning agent.
Remove the appliance content and storage it at a
cool location.
After everything was thoroughly dried, you can
restart the operation.
Defrosting
The appliance keeps free from ice inside because of
the NoFrost System. A defrosting procedure isn´t
necessary.
