1. SAFETY INSTRUCTIONS

The following instructions contain important safety precautions and should be strictly observed.

WARNING

1.When there is no need to energize the unit during disassembly or cleaning, be sure to unplug the unit or disconnect the main power supply before servicing the unit to prevent electric shocks.

2.If the unit must be energized for inspection of the electric circuit, use rubber gloves to avoid contact with any live parts, which may result in electric shocks.

3.Check for proper ground connections, and repair if necessary to prevent electric shocks.

4.Always use service parts intended for the applicable model for replacement of defective parts. Use proper tools to secure the wiring. Otherwise abnormal operation or trouble may occur and cause electric leaks or fire.

5.Check for proper part installations, wiring conditions and soldered or solderless terminal connections to avoid smoke, fire or electric shocks.

6.Be sure to replace damaged or deteriorated power cords and lead wires to prevent electric shocks, flames or smoke.

7.Lead wires using solderless terminals or the like must be bound with their closed ends up to avoid entrance of moisture that could lead to electric leaks or fire.

8.After servicing, always use a megohmmeter (500VDC) to check for the insulation resistance of minimum 1 megohm between the live part (attachment plug) and the dead metal part (ground terminal). Negligence in checking may cause electric leaks or shocks.

9.Do not service the electrical parts with wet hands to prevent electric leaks or shocks.

10.Always ask the user to keep children away from the work area. They may be injured by tools or disassembled products.
