Chapter 1 General Information
1-1. General Guidelines
When servicing, observe the original lead dress. If a short circuit is found, replace all parts which
have been overheated or damaged by the short circuit. After servicing, see to it that all the protective
devices such as insulation barriers, insulation papers shields are properly installed. After servicing,
make the following leakage current checks to prevent the customer from being exposed to shock
hazards.
1) Leakage Current Cold Check
2) Leakage Current Hot Check
3) Prevention of Electro Static Discharge (ESD) to Electrostatic Sensitive
1-2. Insurance Test
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 60Hz.
10. A big fluctuation of voltage (exceed the range 187～242V) may cause a start failure of the
refrigerator, a burn-out of the control panel and compressor, or an abnormal sound 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. 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.
13. 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.
14. 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.
