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

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 115V with a frequency of 60Hz.
10. A big fluctuation of voltage 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.
11. Take care not to damage the supply line. Don’t yank at the line; pull the plug out gently from the

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.
