WARNING
Electrostatic discharge and spark for-

On a damaged / leaking refrigerant circuit,
sparks may ignite escaping refrigerant. Fire
hazard.
▪ Use a damp cloth or sponge to remove
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 recommended by the manufacturer.
Appliances with explosion protection mark-
ings (see →Explanation of symbols) are
permitted.

12.1 Defrosting
Responsibility
–
Operating companies
–
Operating personnel
The appliance does not have an automatic defrosting
NOTE
Material and property damage from ice for-
mation on the cooling surfaces.
▪ The operating company must defrost the appliance
completely at regular intervals (complete defrost-
ing).
For hygienic reasons, complete defrosting must be
carried out (see →Complete defrosting).
12.1.1 Complete defrosting
We recommend combining the complete defrosting
with the basic cleaning.
Defrosting interval
–
For hygienic reasons, at least every six months
–
If ice forms on the cooling surfaces
Carrying out a complete defrosting
Carrying out a complete defrosting is equivalent to the
cleaning steps with the cooling function switched off.
(see page 16, chapter 12.2.1).
12.2 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.
WARNING
Damage to the electrical system and
refrigerant circuit due to the use of
steam and high-pressure cleaners.
Contact with live parts may result in electric
shock.
Flammable refrigerant can escape and cause
an explosive gas/air mixture. Fire hazard due
to sparking or overload.
▪ Do not use any steam or high-pressure
cleaners.
CAUTION
Material breakage.
Falling hazard. Cuts.
▪ Do not climb onto or into the appliance.
▪ Do not apply any load to the lid.
For safety when handling glass, see →Mechanical
hazards
Use protective gloves when cleaning.
