Usage Precautions
• 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.
• The temperature display value of refrigerator refers to the temperature value at the temperature
sensing probe inside the refrigerator. Though the temperature displayed is diff erent from the actual
one at the center of refrigerator, it will approach to the real temperature gradually.
• Clean the refrigerator with mild detergent water. 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 if the refrigerator will be out-of-service for a long time.
• Reduce the time of keeping door open when storing or taking articles each time, to prevent great
fl uctuation 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 16~32℃ ; if the humidity is higher than
70%,condensation will occur on the glass door(HYC-68A) in high temperature and high humidity
condition, which is normal and will not aff ect the storage temperature inside the refrigerator; in the
event of condensation, please improve ventilation conditions as soon as possible and reduce ambient
temperature simultaneously.
• Please keep the article inside at least 20mm away from the cabinet back wall!
• The maintenance should be supplied by professional after-sales service people once the equipment
is faulty.
Meaning of crossed –out wheeled dustbin:
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 landfi lls or dumps, hazardous substances can leak into the groundwater
and get into the food chain, damaging your health and well-being.
