2.5.3 | Flammable refrigerants
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 away from sources of ignition (heat,
sparks, open flames, hot surfaces).
▪ Use a damp cloth or sponge to remove
condensation and for cleaning. Do not use
dry cloths or sponges to rub dry. (Risk of
electrostatic charge and sparking).
▪ Do not close the ventilation openings in the
unit housing. Only use original accessories.
▪ Do not use any mechanical devices or
other means (e.g. ice scraper) 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.
Devices with explosion protection markings
(see → Explanation of symbols) are permit-
ted.
▪ Do not use steam or high-pressure clean-
ers for basic cleaning.
▪ 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 temperat-
ures higher than 70°C (158°F) during trans-
port and storage.
▪ Avoid transmitting pulsations and vibrations
to the device.
▪ Avoid external force on the device such as
careless action with a lift truck or floor
cleaning machine.
▪ The operator must not drill into the appli-
ance or carry out any other work on it.
▪ Do not squeeze or bend pipes.
▪ Only qualified staff may carry out work on
the refrigerant circuit.
▪ Only open the refrigerant circuit and suck
off the refrigerant in well-ventilated rooms
outside store business hours (when cus-
tomers are not present) or outdoors.
▪ Before any maintenance, service or repair
work, disconnect the device (see →Shut-
down). Secure the device against being
switched on again.
