Precautions for Use
Reduce the time of keeping door open when storing or taking articles each time, to prevent great
fluctuation to the temperature and humidity inside the refrigerator.
The refrigerator will see a sharp temperature increase in a short time when the door is opened,
which is normal, and the temperature will resume 1h after the door is closed.
The refrigerator shall operate with ambient temperature as 10~32℃and humidity less than 85%;
condensation will occur on the glass door in high temperature and high humidity condition, which
is normal and will not affect the storage temperature inside the refrigerator; in the event of
condensation, please improve ventilation conditions as soon as possible and reduce ambient
temperature simultaneously.
The temperature display value of refrigerator refers to the temperature value at the temperature
sensing probe inside the refrigerator. Though the temperature displayed is different from the actual
one at the center of refrigerator, it will approach to the real temperature gradually.
The refrigerator battery may be low when the refrigerator is restarted after it has been out-of-service
for a long time; make sure the battery switch is set at “ON” and charge the storage battery, which
will be full after continuous running of refrigerator for one week.
Make sure the temperature inside the refrigerator has reached the set value and put articles in the
refrigerator by batch. Volumes accounted by articles shall not be greater than 1/3 of refrigerator to
prevent rise of temperature.
Clean the refrigerator with neutral detergent diluted. Brushes, acids, gasoline, soap powders,
polishing powders or hot water are prohibited to clean refrigerator as these materials may damage
the painting surface and plastic & rubber components and parts. Never wipe the plastic & rubber
components and parts with volatile solvent such as gasoline.
Shut off the power as well as the battery switch if the refrigerator will be out-of-service for a long
time.
Do not dispose of electrical appliances as unsorted municipal waste, use separate collection
facilities.Contact you local government for information regarding the collection systems available.
If electrical appliances are disposed of in landfills or dumps, hazardous substances can leak into
the groundwater and get into the food chain, damaging your health and well-being.When replacing
old appliances with new ones, the retailer is legally obligated to take back your old appliance for
disposals at least free of charge.

Do not damage refrigerating circuit.
Do not use electrical apparatus without production permit in the refrigerator.
The refrigerator is capable of memorizing set value. When power restores after outage, the
refrigerator will continue operating according to set parameter before last outage.
The refrigerator shall be reconnected after more than 5 minutes once it is shut
off, to prevent damage to compressor or system.
If the refrigerator is left unused in areas where supervision is unavailable for a
long time, make sure children will not get close to the refrigerator and the door
can not be completely closed.
