This 

SERVICE MANUAL

provides various service 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. When servicing the unit, set the ROTARY SWITCH

or POWER SWITCH to OFF and unplug the power
cord.

2. Observe the original lead dress.

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. Unplug the power cord and connect a jumper

between 2 pins (black and white).

2. The grounding conductor (green or green & yellow)

is to be open.

3. Measure the resistance value with an ohm meter

between the jumpered lead and each exposed
metallic part on the equipment at all the positions
(except OFF or O) of the ROTARY SWITCH.

4. The value should be over 1M

Ω
