– 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 haz-
ard due to sparking or overload.
§ Do not use steam or high-pressure clean-
ers for basic cleaning.
§ Follow the instructions for main cleaning.
Electrostatic discharge and spark
formation with flammable refrigerant.
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 manufac-
turer. Appliances with explosion protection
markings [see } Chapter 2.1] are permit-
ted.
