1. Precautions

1. Warning: Prior to repair, disconnect the

power cord from the circuit breaker.

2. Use proper parts: Use only exact

replacement parts. (Also, we recommend

replacing parts rather than repairing them.)

3. Use the proper tools: Use the proper tools

and test equipment, and know how to use

equipment may cause problems later-

intermittent contact, for example.

4. Power Cord: Prior to repair, check the

power cord and replace it if necessary.

5. Avoid using an extension cord, and avoid

tapping into a power cord. This practice

may result in malfunction or fire.

6. After completing repairs and reassembly,

check the insulation resistance, Procedure:

Prior to applying power, measure the

resistance between the power cord and the

ground terminal. The resistance must be

greater than 30 megohms.

7. Make sure that the grounds are adequate.

8. Make sure that the installation conditions

are satisfactory. Relocate the unit if

necessary.

9. Keep children away from the unit while it is

being repaired.

10. Be sure to clean the unit and its surrounding

area.

3. Installation and Operating Instructions

3-1 Installation

3-1-1 Selecting Area for Installation

1. Make sure that you install the unit in an area

providing good ventilation. The air conditioner

must not be blocked by any obstacles affecting the

airflow near the air inlet and the air outlet.

2. Make sure that you install the unit in an area that

allows good air handling. The installation area

must be able to endure vibration from the unit.

3. Make sure that you install the unit away from heat

or vapor.

4. Make sure that you install the unit in an area

which is cool and has adequate space.

5. Make sure that you install the unit in an area away

from TVs, audio units, cordless phones,

fluorescent lighting fixtures and other electrical

appliances (at least 1 meter clearance).

6. Make sure that you install the unit in an area which

provides easy drainage for condensed water.

7. Make sure that you install the unit in area not

exposed to the rain or direct sunlight.

(Install a separate sunblind if exposed to direct

sunlight).

8. Make sure that you install the unit in an area

allowing good air movement. Do not install it in

a space that would cause noise amplification

of noise.

9. Fix the unit firmly if mounted in a high place.

Caution:

Do not use the air conditioner in the following environments : greasy areas (including areas near machines),

or marine areas. Contact your local dealer for advice.

3-2 Controls and Components

3-2-1 Thermostat

OFF :

When room temperature is lowered by the air

conditioner, the gas within the thermostat will

contract and cause a break in the electrical

contact. The compressor will then stop.

After the compressor stops, the room

temperature will rise.

ON :

As the room temperature increases to a

selected level, the gas within the thermostat

expands causing electrical contact, which

provides the source of electric power to the

compressor. The room temperature will fall

and the cycle will repeat.

Control Operation :

By turning the control knob clockwise (toward

higher numbers), the temperature will be cooler.

By turning the control knob counterclockwise

(toward lower numbers), the temperature will be

warmer.

Level 1 : Cool air will be supplied above 30~35¡C

Cool air will cease below 28~32.5¡C

Level 12 : Cool air will be supplied above 17.4~20.4¡C

Cool air will cease below 14.4~17.4¡C

3-2-2 Operation

3-2-4 Air Swing Switch(AW07A1SE/AW09A1SE)

The fan selector switch offers high and low fan cooling control levels to assure maximum comfort.

The two fan speeds allow you to economically circulate room air flow on days when intense cooling is not required. When

combined with the thermostat(set to call for conditioned air), these controls cool, dehumidify, filter, and circulate room air,

with the fan continuing to circulate air even when the compressor is turned off.

3-2-3 Ventilation Control

Use the ventilation switch to exhaust unfresh air.

Open position : The air inside the room circulates, while exhausted is sent outside.

Closed position : The air inside the room circulates without exhaust.

¥ ON ( ) : Automatic oscillation distributes the air flow throughout the room

(controls left and right wave fins)

¥ OFF( ) : Maintains a fixed direction of air flow, Set the Air Swing switch to OFF at the instant the wave

fins come to the desired position.

Put approximately 10cc oil into a transparent container and test it.

4-2-1 Oil quality

4-2-2 Changing and adding refrigerant oil

1. Change the compressor - DO NOT recharge the oil as the compressor itself is

already charged.

2. Change the condenser .... add 50cc

3. Change the evaporator .... add 50cc

4. When the refrigerant is replaced .... add 30cc oil.

5. After vacuum is completed, the oil is filled through the high pressure side.

6. In the event of a refrigerant leak, generally it is not necessary to add oil.

(unless the oil has leaked significantly).
