SAFETY RECAUTIONS
1. Check if there is any leak of current.
2. Cut out the power supply before the repair to avoid an electrical shock hazard.
3. In the case of a live-line test, insulating gloves should be worn to avoid potential electrical shock.
4. Confirm the rated current, voltage and capacity before testing with any kinds of instruments.
5. Watch if the upper door is open when you check something at a lower position.
6. Take out every part in the cabinet before moving the machine, especially things like panels (e.g. glass
shelf).
7. Please wear intact cotton gloves when repair any parts of the evaporator, so that scratches by the
sharp fins can be avoided.
8. If there is a breakdown with the refrigeration system, please surrender the machine to the service
center, else the leaked refrigerant may pollute the atmosphere.
9. The refrigerator use AC of 220V with a frequency of 50Hz.
10. A big fluctuation of voltage (exceed the range 220～240V) may cause a start failure of the refrigerator,
a burn-out of the control panel and compressor, or an abnormal sound from the compressor in
operation. In this condition an automatic voltage regulator over 750W should be added.
11. Take care not to damage the supply line. Don’t yank at the line; pull the plug out gently from the
receptacle. Don’t press the line under the cabinet or step on it. Take care not to roll on or damage the
supply line when moves the machine from the wall.
12. Don’t use the supply line any more when there is damage to the line or an abrasion to the plug. Go to
the authorized service center for a replacement.
13. In the case of leakage of inflammable gases like carbon monoxide, open the door and windows. Don’t
pull out or insert the plugs of the appliance.
14. This product is designed only for household use. Any put of medicine, dangerous flammable,
explosive articles and highly corrosive acid or base is forbidden.
15. It is recommended not to put any receptacles, stabilized power supply or appliances like microwave
oven on the board of the refrigerator. Don’t use appliance within the refrigerator (except recommended
type), else there may be electromagnetic interference or other accidents.
16. Don’t store or use gasoline and other flammable articles near the refrigerator which may lead to a fire

accident.
17. Don’t hook on the door, else the door may be slanted or the machine may be tipped over and injure
people.
18. Don’t place unstable articles on the refrigerator (e.g. weights and containers with water), else the
weights may hit people and the leaked water may cause leak of current.
19. Don’t touch the refrigeration surface of the freezing compartment when the refrigerator is in operation,
especially when your hand is wet, else you may be glued to the surface.
20. Don’t spray at the refrigerator, or locate it at a damp place, else the insulation of the refrigerator may
be impaired.
21. Any disassembly or alternation to the refrigerator is strictly forbidden. Damage to the refrigeration
pipeline is prohibited. Service to the refrigerator must be carried out by professionals.
22. Don’t put bottles of bear and other drinks into the refrigerator; else the bottles may be cracked with
cold.
23. Pull out the plug of power supply during clearance or power outage. Wait at least five minutes to
resume the power supply in order to prevent damage to the compressor caused by continuous restart.
24. Remove the door and the door seal when the refrigerator is out of use, in case that accident may
happen to children coming in to play.
