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).

a burn -out o f the control p anel and compressor, or an abn ormal sound from the co mpressor 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

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 insula tion of the re frigerator may
