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 sufcient 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 offers the
most efcient 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 lled 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 efciency.
• 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 efciency.
• Open the door only as briey as necessary to minimise cold loss. Opening the door
briey 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
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 rst 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 sh (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.
15
CLEANING AND MAINTENANCE
Defrosting
• The refrigerator is made based on the air-cooling principle and thus has
automatic defrosting function. Frost formed due to change of season or
temperature may also be manually removed by disconnection of the appliance
from power supply or by wiping with a dry towel.
Cleaning of door tray
• According to the direction arrow in the gure
below, use both hands to squeeze the tray, and
push it upward, then you can take it out.
• After washing the tray having been taken
out, you can adjust its installing height in
accordance with your requirement.
Cleaning of glass shelf
• As the innermost part of the refrigerator liner
where contacting the shelves has a backstop,
you shall raise the shelves upward, then you
can be able to take it out.
• Adjust or clean the shelves according to your
requirement.
Cleaning the vegetable drawer
• Remove the contents of the drawer. Hold the
handle of the vegetable drawer and pull it out
completely until it stops.
• Lift the vegetable drawer up and remove it by
pulling it out.
ATTENTION
Soft towels or sponge dipped in water and non-corrosive neutral detergents are suggested
for cleaning. The freezer of shall be nally cleaned with clean water and dry cloth. Open the
door for natural drying before the power is turned on. Do not use hard brushes, clean steel
balls, wire brushes, abrasives, such as toothpastes, organic solvents (such as alcohol, acetone,
Isoamyl acetate, etc.), boiling water, acid or alkaline items clean refrigerator considering that
this may damage the fridge surface and interior.

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.

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 overows
• 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 owing inside of the appliance may
produce creak, which is normal.
