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, 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.

1.2

INSULATION RESISTANCE TEST

1. Unplug the power cord and connect a jumper
between 2 pins (black and white).

2. The grounding conductor (green) 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) of the ROTARY SWITCH.

4. The value should be over 1MΩ.

1.5.1 COOLING ONLY MODEL

• VENTILATION

The ventilation lever must be in the CLOSE position
in order to maintain the best cooling conditions.
When a fresh air is necessary in the room, set the
ventilation lever OPEN position.
The damper is opened and room air is exhausted.

• THERMOSTAT

Thermostat will automatically control the temperature
of the room. Select a higher number for a cooler
temperature in the room. The temperature is selected
by positioning the knob to the desired position.
The 5 or 6 position is a normal setting for average
conditions.

• Built-in adjustable THERMOSTAT

• Washable one-touch filter

• Compact size

• Reliable and efficient rotary compressor is equipped.

• OPERATION

Off - Turns air conditioner off.

Med Fan - Med speed fan operation without cooling.

Low Fan - Low speed fan operation without cooling.

High Cool - Cooling with high speed fan operation.

Med Cool - Cooling with med speed fan operation.

Low Cool - Cooling with low speed fan operation.
