1. PREFACE
This SERVICE MANUAL provides various servicing information, including the mechanical and electrical parts,
etc. This room air conditioner was manufactured and assembled under a strict quality control system.
The refrigerant is charged at the factory. Be sure to read the safety precautions prior to servicing the unit.
1.1 SAFETY PRECAUTIONS
1. When servicing the unit, set the POWER SWITCH to OFF and unplug the power cord.
2. Inspect the service cord for damage or wear.
If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit.
3. After servicing the unit, make an insulation resistance test to protect the customer from being exposed to
shock hazards.
1.2 INSULATION RESISTANCE TEST
1. Unplug the power cord and connect a jumper lead between the two (2) live pins.
2. The grounding conductor (yellow/green) is to be open.
3. Measure the resistance value with an ohm meter between the jumped lead and each exposed metallic part
on the equipment at all the positions (except OFF) of the ROTARY SWITCH or POWER SWITCH.
4. The value should be over 1M
