Retrofitting drawers
When retrofitting drawer systems in Liebherr refrigera‐
tors/freezers that are used to store temperature-sensitive
materials such as medicines requiring refrigeration and
refrigerated goods that are subject to special standard
requirements, a temperature qualification is required.
Retrofitting drawers in Liebherr refrigerators/freezers can
lead to spoilage of the stored goods or damage to
the stored goods. Therefore, retrofitting must only be
carried out by authorised service providers of the refriger‐
ator/freezer manufacturer.

3.1 Installation requirements
The installation conditions are crucial to ensure that you
can operate your appliance safely, efficiently and without
problems.
-
Observe all safety instructions.
-
Consider the location and position in the room.
WARNING
Danger of fire due to incorrect positioning!
If the mains cable or plug touches the back of the appli‐
ance, the vibration can damage the mains cable or the plug
resulting in a short circuit.
► Make sure the mains cable is not trapped under the appli‐
ance when you position the appliance.
► Stand the appliance so that it is not touched by connec‐
tors or main cables.
► Do not connect any appliances to sockets in the area of
the back of the appliance.
► Do not place and operate multi-sockets/power distribu‐
tors and other electronic devices (such as halogen trans‐
formers) at the back of the appliances.
WARNING
Fire hazard due to dampness!
If live parts or the mains lead become damp this may cause
short circuits.
► The appliance is designed for use in enclosed areas. Do
not operate the appliance outdoors or in areas where it is
exposed to splash water or damp conditions.
WARNING
Leaking coolant and oil!
Fire. The coolant contained in the appliance is eco-friendly,
but also flammable. The oil contained in the appliance
is flammable. Escaping coolant and oil can ignite if the
concentration is high enough and in contact with an
external heat source.
► Do not damage the pipelines of the coolant circuit and
the compressor.

at the installation site.
-
The more refrigerant there is in the appliance, the larger
than room must be in which it is located. In rooms that
are too small, a leak can product a flammable gas/air
mixture. For every 8g of refrigerant, the installation room
must be at least 1 m
3
in size. Information on the refrig‐
erant contained is given on the type plate inside the
appliance.

9.2 Defrosting appliance
WARNING
Improper defrosting of the appliance!
Injuries and damage.
► Do not use mechanical equipment or other methods to
speed up the defrosting process other than those recom‐
mended by the manufacturer.
► Do not use electrical heating or steam-cleaning appli‐
ances, naked flames or defroster sprays to defrost.
► Do not use sharp objects to remove ice.
To maintain the functionality of the appliance, we recom‐
mend defrosting it when there is a high buildup of ice.
Icing in the interior is determined by the location (e.g.
high humidity), settings on the appliance and incorrect user
behaviour.
If automatic defrosting is insufficient, defrost the appliance
manually:
► Switch off appliance. (see 7.2.2 Switching appliance on
and off )
► Pull out mains plug.
► Store refrigerated items elsewhere.
► Leave appliance door open during defrosting process.
► Absorb any remaining defrost water with a cloth and
clean the appliance.

12 Disposal
12.1 Preparing appliance for disposal
Liebherr uses batteries in some of its appli‐
ances. In the EU, for environmental reasons,
legislation obliges the end user to remove
these batteries before disposing of old appli‐
ances. If your appliance contains batteries, a
corresponding notice is attached.
Lamps If you can remove the lamps yourself without
destroying them, also remove these before
disposal.
► Take the appliance out of operation.
► If possible: remove lamps without destroying them.
12.2 Disposing of the appliance in an
environmentally friendly manner
The appliance still contains
valuable materials and must
be disposed of separately from
unsorted municipal waste.
Dispose of batteries separately
from the old appliance. To do
this, you can return the batteries
free of charge to retailers as
well as recycling centres and
collection centres for recyclable
materials.
Lamps Dispose of removed lamps
via the respective collection
systems.
For Germany: You can dispose of the appli‐
ance free of charge via the
class 1 collection containers
at the local recycling and
recyclable material collection
centres. When purchasing a new
fridge/freezer, if the sales area
> 400 m
2
, retailers will also take
back the old appliance free of
charge.
WARNING
Leaking coolant and oil!
Fire. The coolant contained in the appliance is eco-friendly,
but also flammable. The oil contained in the appliance
is flammable. Escaping coolant and oil can ignite if the
concentration is high enough and in contact with an
external heat source.
► Do not damage the pipelines of the coolant circuit and
the compressor.
► Observe the notes on transporting the appliance.
(see 3.3 Transporting the appliance)
► Transport the appliance without damaging it.
► Dispose of batteries, lamps and the appliance according
to the above specifications.
