Tips for saving energy

■

Install the appliance in a dry, well 

ventilated room! The appliance should 

not be installed in direct sunlight 

or near a heat source (e.g. radiator, 

cooker).
If required, use an insulating plate.

■

Allow warm food and drinks to cool 

down before placing in the appliance!

■

When thawing frozen products, place 

them in the refrigerator. Use 

the coldness of the frozen food 

to cool food.

■

Open the appliance as briefly 

as possible.

■

Regularly defrost the freezer 

compartment to remove the layer of 

frost!
A layer of hoarfrost will impair 

refrigeration of the frozen food 

and increase power consumption.

■

Ensure that the freezer compartment 

door is always closed properly.

■

Occasionally clean 

the rear of the appliance 

with a vacuum cleaner or paint brush 

to prevent an increased power 

consumption.

Operating noises

switching on/off.

Preventing noises

The appliance is not level

Please align the appliance with a spirit 

level. If required, place something 

underneath.

The appliance is not free-standing

Please move the appliance away 

from adjacent units or appliances.

Containers or storage areas wobble 

or stick

Please check the removable parts 

and re-insert them correctly if required.

Bottles or receptacles are touching 

each other

Move the bottles or receptacles slightly 

away from each other.
