foam pads and tapes inside of the refrigerator;
tear off the protective film on the doors and the refrigerator body.
• Keep away from heat and avoid direct sunlight. Do not
place the freezer in moist or watery places to prevent rust
or reduction of insulating effect.
• Do not spray or wash the refrigerator; do not put the refrigerator in
moist places easy to be splashed with water so as not to affect the
electrical insulation properties of the refrigerator.

the ground shall be fiat, and sturdy (rotate left or right to
adjust the wheel for levelling if unstable).
• The top space of the refrigerator shall be greater than 30cm, and
The refrigerator should be placed against a wall with a free distance
more than 10cm to facilitate heat dissipation.

Changing the Light
Any replacement or maintenance of the LED lamps is intended to be made by
the manufacturer, its service agent or similar qualified person.
2.5
Starting to use
JlJ
• Before initial start, keep the refrigerator still for half an hour
before connecting it to power supply.
• Before putting any fresh or frozen foods,the refrigerator shall have run
for 2-3 hours, or for above 4 hours in summer when the ambient
temperature is high.
595
• Spare enough space for convenient opening of the doors and drawers or
statement by the distributor.
2.6 Energy saving tips
• The appliance should be located in the coolest area of the room, away from heat
producing appliances or heating ducts, and out of the direct sunlight.
• Let hot foods cool to room temperature before placing in the appliance. Overloading
the appliance forces the compressor to run longer. Foods that freeze too slowly may
lose quality, or spoil.
• Be sure to wrap foods properly,and wipe containers dry before placing them inthe
• appliance. This cuts down on frost build-up inside the appliance.
Appliance storage bin should not belined with aluminum foil, wax paper,or paper
• toweling. Liners interfere with cold air circulation, making the appliance less efficient.
Organize and label food to reduce door openings and extended searches. Remove as many
items as needed at one time, and close the door as soon as possible.

4. Maintenance and care of the appliance
4.1 Overall cleaning
• Dusts behind the refrigerator andon the ground shall be timely cleaned to improve the cooling effect and
energy saving.
• Check the door gasket regularly to make sure there are no debris. Clean the door gasket with a soft cloth
dampened with soapy water or diluted detergent.
• The interior of the refrigerator should be cleaned regularly to avoid odor.
• Please turn off the power before cleaning interior, remove all foods, drinks ,shelves, drawers, etc.
• Use a soft cloth or sponge to clean the inside of the refrigerator, with two tablespoons of baking soda and
a quart of warm water. Then rinse with water and wipe clean. After cleaning, open the door and let it dry
naturally before turning on the power.
• For areas that are difficult to clean in the refrigerator (such as narrow sandwiches, gaps or corners), it is
recommended to wipe them regularly with a soft rag, soft brush, etc. and when necessary, combined with
some auxiliary tools (such as thin sticks) to ensure no contaminants or bacterials accumulation in these
areas.
• Donot use soap, detergent,scrub powder, spray cleaner,etc., as these may cause odorsin the interior of
the refrigerator or contaminated food.
• Clean the bottle frame, shelves and drawers with a soft cloth dampened with soapy water or diluted
detergent. Dry with a soft cloth or dry naturally.
• Wipe the outer surface of the refrigerator with a soft cloth dampened with soapy water, detergent, etc., and
then wipe dry.
• Donot use hard brushes, clean steel balls, wire brushes,abrasives
(such as toothpastes),organic solvents (such as alcohol, acetone,
banana oil, etc.), boiling water, acid or alkaline items, which may
damage the fridge surface and interior. Boiling water and organic
solvents such as benzene may deform or damage plastic parts.
• Do not rinse directly with water or other liquids during cleaning to
avoid short circuits or affect electrical insulation after immersion.
A Please unplug the refrigerator for defrost and cleaning.
4. 2 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.
EN-13

4.3 Out of operation
• Power failure: In case ofpower failure, even if it is in summer, foods inside the appliance can be kept for
several hours; during the power failure, the times of door opening shall be reduced, and no more fresh
food shall be put into the appliance.
• Long-time nonuse:The appliance shall be unplugged and then cleaned; then the doors are leftopen
to prevent odor.
• Moving: Before the refrigerator ismoved, take all objects inside out, fix the glass partitions, vegetable holder,
freezing chamber drawers and etc. with tape,and tighten the levelling feet; close the doors and seal them
with tape. During moving, the appliance shall not be laid upside down or horizontally,or be vibrated;
the inclination during movement shall be no more than 45°.
A The appliance shall run continuously once it is started. Generally, the operation of the appliance
shall not be interrupted; otherwise the service life may be impaired

5 Trouble shooting
5.1 You may try to solve the following simple problems by yourself.
If them cannot be solved, please contact the after-sales department.
Failed operation
Odor
Long-time operation
of the compressor
Light fails to get lit
Doors cannot be
properly closed
Loudnoise
Door seal fails to
betight
Water pan overflows
Hot housing
Check whether the appliance isconnected to power or
whether the plug is in well contact
Check whether the voltage is toolow
Check whether there is a power failure or partial circuits have tripped
Odorous foods shall be tightly wrapped
Check whether there is any rotten food
Clean the inside of the refrigerator
Long operation of the refrigerator is normal insummer
when the ambient temperature is high
It isnot 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
Check whether the refrigerator is connected to power supply and
whether the illuminating light is damaged
Have the light replaced by a specialist
The door isstuck by food packages
The refrigerator is tilted
Check whether the floor is level and whether the refrigerator isplaced stably
Check whether accessories are placed at proper locations
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)
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 dueto entry
of air and increased water due to defrosting.
Heatdissipationof the built-incondenser viathe housing, whichis normal
When housing becomes hot due to high ambient temperature,
storage of too much food,
provide sound ventilation to facilitate heat dissipation.
Condensation on the exterior surface and door seals of the refrigerator
Surface condensation isnormal when the ambient humidity is too high. Just wipe the condensate
with a clean towel.
Buzz: The compressor may produce buzzes during operation,
and the buzzes are loud particularly upon start or stop. This is normal.
Abnormal noise
Creak: Refrigerant flowing inside of the appliance may produce creak,
which is normal.
