Specific hazards

2.5.1 Electrical voltage

Only qualified staff may carry out work on the electrical
system.
In case of fault messages or damage to the device,
contact maintenance service (see →Maintenance ser-
vices).
WARNING
Contact with live parts may result in
electric shock.
Fire hazard due to sparking or overload.
▪ Do not connect a damaged device or dam-
aged parts (such as connecting cables) to
the power supply.
▪ Check to ensure safety devices are com-
plete and working.
▪ Do not remove protective devices and cov-
ers attached to the appliance.
▪ Before connecting to the power supply, ob-
serve the following:
- Applicable local electrical safety regula-
tions.
- Applicable standards and safety instruc-
tions.

- Information on the rating plate (see →
Rating plate and serial number).
- Mains voltage and mains frequency must
match the information on the rating plate.
▪ Only previously trained staff may cut power
of the device.
▪ Observe the following safety rules if the ap-
pliance is damaged during operation or
prior to maintenance:
1. Disconnect the appliance (switch off all
sources of electrical power).
2. Secure the appliance against reconnec-
tion.
▪ Only qualified staff may replace damaged
parts, e.g. connecting cables.
▪ Do not squeeze or bend the mains power
cable.
▪ Do not use extension cords or multiple
socket strips.
▪ Do not use steam or high-pressure clean-
ers for basic cleaning.
▪ Do not damage concealed electrical parts.
The operator must not drill into the appli-
ance or carry out any other work on it.

2.5.2 Refrigerant circuit

Only qualified personnel may carry out work on the re-
frigerant circuit.
In case of fault messages or damage to the device,
contact maintenance service (see →Maintenance ser-
vices).
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.
