1.7 Saving energy
-Pay attention to good ventilation. Do not cover ventilation
holes or grids.
-Do not install the appliance in direct sunlight, next to an
oven, radiator or similar.
-Energy consumption depends on the installation condi‐
tions, e.g. the ambient temperature (see 1.2 Appliance
range of use) . A warmer ambient temperature can
increase the energy consumption.
-Open the appliance for as short a time as possible.
-The lower the temperature is set the higher the energy
consumption.
-Sort your food: home.liebherr.com/food.
-Keep all food properly packed and covered. This prevents
frost from forming.
-Only take food out for as long as necessary so that it
doesn’t warm up too much.
-Inserting warm food: allow to cool down to room temper‐
ature first.
-Thaw frozen food in the refrigerator.
-If there is a thick layer of frost in the appliance: defrost
the appliance.
Dust deposits increase energy consump‐
tion:
-For refrigerators with heat exchangers
dust the metal grid on the back of the
appliance once a year.

tors and other electronic devices (such as halogen trans‐
formers) at the back of the appliances.
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.
uDo not damage the pipelines of the coolant circuit and
the compressor.
WARNING
Fire hazard and danger of damage!
uDo not place appliances emitting heat e.g. microwaves,
toasters etc. on the appliance!
NOTICE
Covered vents!
Damage. Appliance can overheat, which can reduce the
service life of various parts of the appliance and lead to
operational impairments.
uAlways make sure there is good ventilation.
