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 1MΩ.

1.4 FEATURES

• Designed for cooling only.

• Powerful and quiet.

• Slide out chassis for the simple installation and service.

1.5 CONTROL LOCATIONS

1.5.1 COOLING ONLY MODEL

• OPERATION

• Built in adjustable THERMOSTAT.

• Washable one-touch filter.

• Compact size.

• VENTILATION

Push the lever to the "CLOSE" position to cool, heat or recirculate room air only. Pull the lever to the "OPEN" position to exhaust smoke or stale air from the room. This feature is best used in conjunction with the FAN ONLY position.

PULL OPEN / PUSH CLOSE

When the air conditioner has been operating in the cooling and is turned off or set to the fan only position, wait at least 3 minutes before resetting to the cooling operation again.
