SAFETY
• To prevent possible injury due to an electrical
shock, be sure to disconnect the power cord or
turn off the circuit breaker before replacing the
interior light or cleaning the appliance.
Electrical Safety
Connect this appliance to a 110-120 VAC, 15 amp
circuit that is controlled by a circuit breaker or
fuse. This appliance should have its own separate
grounded circuit. Do not use an extension cord.
• To prevent possible injury due to broken glass,
use hand protection when replacing the interior
light.
The power cord is equipped with a three-prong
(grounding) plug for your protection against pos-
sible shock hazards. To maintain this protection:
• To avoid injury or damage to the appliance, do
not use steam cleaning equipment to clean the
appliance.
• Do not modify the plug by removing the round
grounding prong.
• Do not operate the wine cooler in the presence
of explosive fumes.
• Do not use a two-prong adapter. Where a two-
prong wall receptacle is encountered, contact
a qualified electrician and have it replaced with
a three-prong receptacle in accordance with all
local codes and ordinances.
• In the event of a power outage, minimize open-
ing the door.
• To protect the wine cooler from possible dam-
age, allow the appliance to stand 1/2 to 1 hour
in place before turning the electricity on. This
allows the refrigerant and system lubrication to
reach equilibrium.
• Do not use a power cord that is frayed or dam-
aged.

WINE COOLER COMPARTMENT
Interior Lighting - Figures 14 - 15
Additional Features
Pull-out Racks - Figure 16
The pull-out racks allows bottles of wine to be
viewed and removed more easily. The control ele-
ment panel shelf cannot be removed.
The interior light emits class 1M laser
radiation. DO NOT look directly at light or
through any optical instruments when the
light defuser is removed. Severe eye injury
can occur.
Labels
The appliance is supplied with a label holder
with labels for each rack. Use these to label
the type of wine stored on each shelf. Use a
soft pencil on the labels so that you can erase
it again when necessary. Additional labels
can be obtained from your Liebherr Dealer or
Distributor.
A lightbar is integrated into the upper and lower
compartments.

WINE COOLER COMPARTMENT
Storage Diagram - Figure 18
It is possible to store up to 46 Bordeaux bottles of
750 ml each in your wine cooler.
Air Exchange with Activated
Charcoal Filter - Figure 17
The way in which wines continue to mature depends
on the ambient conditions. The quality of the air
is therefore decisive for preserving the wine.Your
Liebherr wine cooler is equipped with an activated
charcoal filter in the interior rear wall of both the
upper and lower compartments.
We recommend you replace the filter at least once
a year. Filters can be obtained from your Liebherr
Dealer or Distributor.
Removing the filter: Hold the filter by the handle.
Turn it 90° to the left or right and remove.
Reinstalling the filter: Insert with the handle in a
vertical position. Turn it 90° to the left or right until it
clicks into place.

DEFROSTING/CLEANING
Defrosting
The wine cooler compartment defrosts automatical-
ly. The water that forms on the rear wall drains into
a reservoir at the back of the appliance and evapo-
rates automatically through the compressor heat.
Keep your stainless steel looking new by cleaning
with a good quality stainless steel cleaner or polish
monthly. High quality stainless steel cleaners and
conditioners are commercially available.
DO NOT CLEAN WITH STEEL WOOL PADS or
ABRASIVE PADS. DO NOT use cleaners that
are not for use on stainless steel, such as glass
cleaners, tile cleaners or cleaners used to clean
counter tops.These types of cleaners can dam-
age the surface permanently.
Cleaning
• To prevent possible injury due to an
electrical shock, be sure to disconnect
the power cord or turn OFF the circuit
breaker before replacing the interior
light tube or cleaning the appliance.
• To avoid injury or damage, DO NOT use
steam cleaning equipment to clean
the appliance.
Stainless steel that is exposed to chlorine gas and
moisture may have some discoloration. This discol-
oration is normal. If your unit is used in this environ-
ment, clean and polish your stainless steel more
often.
If the surface discolors or rusting appears, clean
it quickly with a non-abrasive cloth and protect it.
Always clean and polish in the direction of the grain
and finish.
Clean the appliance by hand with lukewarm water
and a little detergent.
DO NOT use abrasive or scouring sponges. DO
NOT use concentrated cleaning agents. NEVER
use abrasive or acid cleaners or chemical solvents
or steam cleaners.
• Ensure no cleaning water penetrates into the
electrical components or ventilation grille.
IMPORTANT
Mold can form on the bottles and labels
depending on the type of adhesive used on
the labels. This can be prevented by care-
fully cleaning any adhesive residues off the
bottles.
• Dry all parts well with a cloth.
• DO NOT damage or remove the model plate on
the inside of the appliance. It is very important
for servicing your appliance.
Remove any dust from the outside of the ventilation
grille (Figure 19) with a vacuum cleaner.
