Tips for energy saving
• Do not place the appliance near cookers, radiators or other heat sources. If the
ambient temperature is high, the compressor will run more frequently and for longer,
resulting in increased energy consumption.
• Ensure that there is sucient ventilation at the base of the appliance, on the sides of
the appliance and at the back of the appliance. Never cover ventilation openings.
• Please also observe the spacing dimensions in the chapter “Installation”.
• The arrangement of drawers, shelves and racks as shown in the illustration oers the
most ecient use of energy and should therefore be retained as far as possible. All
drawers and shelves should remain in the appliance to keep the temperature stable
and save energy.
• To obtain a larger storage space (e.g. for large refrigerated/frozen goods), the
middle drawers can be removed. The top and bottom drawers and shelves should be
removed last if necessary.
• An evenly filled refrigerator/freezer compartment contributes to optimal energy use.
Therefore, avoid empty or half-empty compartments.
• Allow warm food to cool before placing it in the refrigerator/freezer. Food that has
already cooled down increases energy eciency.
• Allow frozen food to defrost in the refrigerator. The coldness of the frozen food
reduces the energy consumption in the refrigerator compartment and thus increases
the energy eciency.
• Open the door only as briefly as necessary to minimise cold loss. Opening the door
briefly and closing it properly reduces energy consumption.
• The door seals of your appliance must be perfectly intact so that the doors close
properly and energy consumption is not increased unnecessarily.

Tips on storing food
Freezer compartment
• The freezer is designated for the storage of food frozen at very low temperature,
long-term storage of frozen food, and for the production of ice.
• Only use the shelves in the door of the freezer to store frozen food, not for storing
hot food designated for freezing.
• Do not put fresh and frozen food next to each other. The frozen food may thaw.
• When freezing fresh food (such as meat, fish or chopped meat), cut them into parts
that can be used at the same time.
• Storing frozen food: instructions are usually stated on the packages, which must be
followed. If there is no information on the packaging, food should not be stored for
longer than three months from the date of purchase.
• When purchasing frozen food, make sure that it was frozen at a suitable temperature
and that the packaging is not damaged.
• Frozen food should be kept in suitable packages to retain the quality and should be
returned to the freezer compartment as soon as possible.
• If a package of frozen food shows moisture or abnormal bulging, it is probable that
it was stored at the wrong temperature and the content is spoiled.
• The storage period for frozen food depends on the room temperature, the
thermostat setting, the frequency of opening the door of the freezer, the type of
food and the time of transporting the product from the shop to the household. Always
follow the instructions printed on the packaging and never exceed the maximum
storage time stated on the package.
Cooling compartment
• To reduce moisture and subsequent ice build-up, never put liquid into the
refrigerator in unsealed containers. Frost tends to concentrate in the coolest parts
of the evaporator. Storing uncovered liquids results in a more frequent need for
defrosting.
• Never put warm foods in the refrigerator. These should first cool down at room
temperature and then be placed so as to ensure adequate air circulation in the
refrigerator.
• Foods or food containers should not touch the back wall of the refrigerator because
they could freeze to the wall. Do not keep regularly opening the door of the
refrigerator.
• Meat and clean fish (packed in a package or plastic foil) can be placed in the
refrigerator, which can be used in 1–2 days.
• Fruit and vegetables without packaging can be placed in the part designated for
fresh fruit and vegetables.
ATTENTION
The optimal temperature setting of each compartment depends on the ambient temperature.
Above optimal temperature is based on the ambient temperature of 25 °C.

17
TROUBLESHOOTING
The following simple issues can be handled by the user. Please call the after-sale
service department if the issues are not solved.
Problem Possible reason
Failed operation
• Check whether the appliance is connected to power or
whether the plug is in well contact.
• Check whether the voltage is too low.
• Check whether there is a power failure or partial circuits have
tripped.
Odor
• Odorous foods shall be tightly wrapped.
• Check whether there is any rotten food.
• Clean the inside of the refrigerator.
Long-time operation
of the compressor
• Long operation of the refrigerator is normal in summer.
• when the ambient temperature is high it is not suggestible
having too much food in the appliance at the same time.
• Food shall get cool before being put into the appliance.
• The doors are opened too frequently.
Light fails to get lit
• Check whether the refrigerator is connected to power supply
and whether the illuminating light is damaged.
• Have the light replaced by a specialist.
Door can not be
properly closed
• The door is stuck by food packages too much food is placed.
• The refrigerator is tiltedr.
Loud noises
• Check whether the floor is level and whether the refrigerator
is placed stably.
• Check whether accessories are placed at proper locations.
18
Problem Possible reason
Door seal fails to be
tight
• Remove foreign matters on the door seal.
• Heat the door seal and then cool it for restoration (or blow it
with an electrical drier or use a hot towel for heating).
Water pan overflows
• There is too much food in the chamber or food stored
contains too much water,resulting in heavy defrosting.
• The doors are not closed properly, resulting in frosting due to
entry of air and increased water due to defrosting.
Hot housing
• Heat dissipation of the built-in condenser via the housing,
which is normal. When housing becomes hot due to high
ambient temperature, storage of too much food or shutdown
of the compressor is shut down, provide sound ventilation to
facilitate heat dissipation.
Surface
condensation
• Condensation on the exterior surface and door seals of the
refrigerator is normal when the ambient humidity is too high.
Just wipe the condensate with a clean towel.
Abnormal noise
• Buzz: The compressor may produce buzzes during operation,
and the buzzes are loud particularly upon start or stop. This is
normal.
• Creak: Refrigerant flowing inside of the appliance may
produce creak, which is normal.
