3 Before starting up
The information in these operating instructions must be read and observed without fail. This is the only way to ensure the
fault-free functioning of the freezer appliance. Safety instructions are identified by the following warning symbols.
Read and observe the op-
erating instructions Caution!
Flammable refrigerant
(hydrocarbons) Warning indicating cold
surfaces
Warning of dangerous
electrical voltage General safety warning Warning indicating crush-
ing of hands
The appliance must be completely disconnected
(all poles) from the power supply before com-
mencing maintenance and repair work
(pull out the mains plug).
The warranty does not cover the free repair of malfunctions resulting from improper installation and handling.
Only trained and qualified personnel are permitted to perform service and repair work on refrigeration
equipment. In the event of repair work, the refrigerant quantity must not exceed the initial fill quantity.
See the type plate for quantity information and material specifications.
Before soldering work is carried out on the refrigeration system, the refrigerant must be drained com-
pletely and the system blown through with dry nitrogen. Only trained and qualified personnel are per-
mitted to dispose of refrigerant and removed components.
Caution: flammable refrigerant (hydrocarbons)
Due to the nature and quantity of the refrigerants used, naked flames are prohibited within a radius of
1 m of the appliance.
Removed components bearing this marking must be disposed of separately.
4 Location of the chest freezer
Always install the appliance on a solid, flat, horizontal indoor surface. The installation room must be at least 24 m
3
in size.
Alternatively, the installation room must be ventilated. Freezer appliances must be positioned at a minimum of 150 mm
away from other appliances or walls so that the aspirated cooling air can circulate freely. The condenser at the back of the
appliance must not be obstructed or blocked.
The ambient temperature must not 28 °C as this would reduce the cooling capacity of the appliance and increase
the temperature in the refrigeration compartment. Effective ventilation in the installation room is usually sufficient to
lower the temperature.
The appliance is not intended for use in areas with an explosion hazard, such as during anesthesia using flammable gases or
vapors. Please refer to the technical data for information on the appliance protection level.
