1. PREFACE

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.

1.1 SAFETY PRECAUTIONS

1. When servicing the unit, turn off the air conditioner

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.

1.2

INSULATION RESISTANCE TEST

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.

4. The value should be over 1M .
