2.5.2 Refrigerant circuit

Only qualified staff may carry out work on the refriger-
ant circuit.
In the event of fault messages or damage to the appli-
ance, contact the maintenance service (see →Mainte-

Flammable refrigerants
WARNING
The refrigerant is highly flammable. If
leaks occur, refrigerant can escape
and cause an explosive gas/air mix-
ture.
This can result in fire and explosion with a
subsequent fire risk.
▪ Refrigerant R-290 (propane) is classified in
safety group A3 according to EN 378-1.
The refrigerant used and the filling quantity
can be seen on the rating plate (see →Rat-
ing plate and serial number).
▪ Keep ignition sources away (heat, sparks,
open flames, hot surfaces).
▪ Use a damp cloth or sponge to remove
condensation water and for cleaning. Do
not use dry cloths or sponges to dry the
appliance. (Risk of electrostatic charge and
sparking)
▪ Do not obstruct the ventilation openings in
the appliance housing. Use only original
accessory parts.
▪ Do not use any mechanical devices or
other means (e.g. ice scrapers) to acceler-
ate the defrosting process.
▪ 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.
▪ Do not use any steam or high-pressure
cleaners.
▪ Only install the appliance in well-ventilated
rooms.
▪ Do not install the appliance in cellars or
lowered rooms.
▪ Ducts and wall bushings must be sealed
under and behind the unit to protect
against fire.
▪ Do not damage the refrigerant circuit.
▪ Do not expose the appliance to tempera-
tures higher than 70°C (158°F) during
transport and storage.
▪ Avoid transmitting pulsations and vibra-
tions to the appliance.
