I. GENERAL INFORMATION
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 fi re.
5. Check for proper part installations, wiring conditions and soldered or
solderless terminal connections to avoid smoke, fi re or electric shocks.
6. Be sure to replace damaged or deteriorated power cords and lead wires to
prevent electric shocks, fl ames 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 fi re.
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.
