keep fruit and vegetables fresh, and avoid any
unpleasant odors.
Do not overfill your refrigerator.
Leave enough space between foods stored in
the refrigerator to keep good air-circulation for
better refrigeration.
Sorting before storage
Sort the foods by category. Place foods to be
used up soon at the front of the shelf so as to
avoid food deterioration as a result of frequent
and
p
rolonged door openings.
Greasy foods may gradually cause corrosion of lining materials. Keep them away from
the walls of the inner compartment. Keep the inner compartment clean and free of oil
stains.
Useful Tips
Thaw frozen food in the refrigerator
compartment; this will help the cooling
performance of the refrigerator compartment and
save energy.
Remove leaves of carrots and radishes before
adding them to the refrigerator, to prevent loss
of nutrients.
Fruits such as rice melon, Chinese quince, sweet
melon, banana and pineapple ripen faster at
lower temperatures, as as a result are not
suitable for refrigerated storage unless you need
them to ri
p
en sooner.
Foods which preserve their freshness at room
temperature, such as onions, garlic and other
roots, need not be stored in the refrigerator.
Freezer Storage Compartment
The Freezer is intended for long-term food storage.
The temperature in the freezer is very low, making it ideal for the storage
of frozen food. Freeze food that you expect to keep stored in the freezer
for a longer period of time; however, but the expiry date indicated on the
packing should be observed.

Freezer Storage Precautions
Allow warm foods to cool down before putting
them into the freezer.
Store food in small packages. This will make it
easier to freeze the food fully and provide better
quality when the food is thawed. Each package
should not exceed 2.5k
g
.
Wrap food before storing. Make sure the
wrappings are dry to prevent them from sticking to
each other. The wrapping materials used should
be odorless, airtight, leak-proof, nontoxic and
environmentally-friendly, to prevent unpleasant
odors or food deterioration.
The food packages should indicate information
such as the food type contained, the date of
storage and the expiry date.
Once thawed, food cannot be returned to the
freezer unless it has been cooked. Thaw out
frozen food according to actual needs.
Do not put too much fresh food in your freezer.
The freezing capacity indicated in the Technical
Data sheet must be observed.
Defrosting • Cleaning
Defrosting the Freezer Compartment
The defrost cycle of the freezer compartment is automatic and no

Power failure
Food can be stored for several hours in the event of
power failure, even in summer.
Do not add foods in the appliance and keep the
doors closed as far as possible when there is a
power failure.
If a power failure is announced beforehand, make
some extra ice cubes and hold them in a le ak-pr oof
container. Place the container on the top shelf in the
refrigerator compartment.
A temperature rise in the freezer due to power interruption or other faults may shorten the
shelf fife of products stored within and have an adverse effect on food quality.
NOTE

tapes.
Keep the door closed during transportation
with adhesive tapes.
When moving the refrigerator, do not tilt it by
more than 45 degrees to prevent the
malfunction of the refrigeration system.
Never place the refrigerator horizontally.
Troubleshooting Tips
When the refrigerator is first plugged in, the
compressor operates for long periods or
switches on and off frequently. In this case, it
will take a longer time for the inner temperature
to reach the desired value.
The refrigerator makes a humming noise when
first plugged in or started up . This sound will
fade away when the refr igerator is in stable
operation.
The external surface of the refrigerator will be
warm, especially when first plugged in, as a
result of its anti-sweat design.
The compressor may produce a humming
sound during operation and a c licking sound
upon starting and stoppin g.
The flow of the refrigerant through the
refrigeration coils may make a babb ling noise.
This noise is usually produced by the
evaporator and compressor. When the
compressor comes to a stop, the refrigerant
backflow of will make a noise like running
water, either from time to time or continuously.
Water dropping onto the defrost h eater can
cause a sizzling or buzzing sound during a
defrost cycle. At the end of a defrost cycle, a
slight popping sound may be heard, and the
evaporator may make a gurgling noise like that
of boiling water.
