WARNING
Electrostatic discharge and spark for-
mation with flammable refrigerant.
On a damaged / leaking refrigerant circuit,
sparks may ignite escaping refrigerant. Fire
hazard.
Use a damp cloth or sponge to re-
move condensation water.
Do not use dry cloths or sponges to
dry the appliance.
Do not operate any electrical devices
(e.g. wet vacuum cleaners) inside
the cooling compartment that do not
correspond to the design recom-
mended by the manufacturer. Appli-
ances with explosion protection
markings (see → Explanation of
symbols) are permitted.
11.1 Defrosting
Responsibility
Operating companies
Operating personnel
The appliance features automatic defrosting.
If there is an increased formation of ice in the inner
container, a semi-automatic defrosting must be
started (see → page 11, chapter 5).
For hygienic reasons, complete defrosting must be
carried out (see page 19, chapter 11.1.1).

11.1.1 Complete defrosting

We recommend combining the complete defrosting
with the basic cleaning.
Defrosting interval
For hygienic reasons, at least every six
months
Carrying out a complete defrosting
Carrying out a complete defrosting is equivalent to the
cleaning steps with the cooling function switched off.
(see page 20, chapter 11.2.1).

11.2 Cleaning

Reasons for regular and thorough cleaning (basic
cleaning):
Ensuring the necessary hygiene. Always keep
the goods area in a clean condition.
Lowest possible energy consumption.
Maintaining trouble-free operation.
Extension of the service life of the appliance.
