4. FUNCTION OF MAIN COMPONENTS

1. ROTARY SWITCH (SELECT OR)

Please refer to the part of selector in the chapter 9 (Wiring Diagram).
The rotary switch (selector) controls the fan motor’s rotation speed, and has five positions.
The function of the five position is as follow.

• OFF: This position stops all operations of the air conditioner.

• HIGH COOL: This position provides the maximum air flow for rapid
cooling, dehumidifying and dust removing operations.
(Use this position on sultry summer days.)

• LOW COOL: This position provides the minimum air flow for quiet
cooling, dehumidifying operations.
(Use this position on suitable for night-time.)

• HIGH FAN: This position provides the maximum air fiow alone fan

operation without cooling operation.

• LOW FAN: This position provides the minimum air flow air flow alone

fan operation without cooling operation.

2. THERMOSTA T (TEMPERATURE CONTROL)

• The Thermostat automatically starts and stops operation in order to keep

the room temperature at a proper level, and this results in efficient use of
power and economical cooling.

• Turn clockwise for a cooler room temperature.

• Turn counter-clockwise for a warmer room temperature.

3. MOT OR

The motor is used to rotate the indoor and outdoor fan so that the room air can be recirculated.

4. F AN

• BLOWER FAN: The Blower draws hot air from the room through the Evaporator and then discharges it back into the
cool air. It circulates the room air.

• PROPELLER FAN: The propeller draws outdoor air through louvering and cools Condenser, and then blows the hot

air out.

5. CAPACIT OR

The Capacitor enlarges the difference of phase between main coil and sub coil so that the Compressor and Fan Motor
starts well.

6. ACCUMULATOR

The Accumulator blocks the unflow of liquid refrigerant and impurities into the Compressor.

5. GENERAL INFORMATIONS

1. CHANGING AIR FLOW DIRECTION

Air flow deflectors divert air from center flow to left or right.
Adjust deflectors for desired air flow pattern.

2. AIR FLOW AR OUND UNIT

Check in door grill and outdoor louvers for air flow obstructions. Do not block air flow to and from unit. The outdoor coil
should be checked and periodically cleaned for debris that may collect and block unit air flow. If air flow is obstructed
or deflected back into unit, the compressor may cycle on and off rapidly, causing early compressor failure.

3. Electrical Grounding Instructions.

This appliance is equipped with a three-prong(grounding) plug for protection against possible shock hazards. If a two­prong wall receptacle is encountered, the customer is required to contact a qualified electrician and have the two­prong wall receptacle replaced with a properly grounded three-prong wall receptacle in accordance with the National
Electrical Code.

4. USE OF EXTENSION CORDS

Because of potential safety hazards under certain conditions we strongly recommend against the use of an extension
cord. However, if you still elect to use an extension cord, it is absolutely necessary that it is earthed and the marked
rating of the extension cord should be 250V 10A or more.

5. DRAIN HOLE AND W ATER DRIPPING OUTSIDE

Locate drain hole at the rear of unit. Water in base pan is picked up by the fan blade and thrown onto the warm
outdoor coil where it evaporates. The air conditioner must be installed level or tited or slightly to the outside for proper
water disposal. On exceptionally hot and humid days the air conditioner may permit excess water to pass thru rear
drain hole or overflow. This should be considered normal.

7

6. CARE AND MAINTENANCE

1. AIR FILTER

Clean the air filter, which removes dust inside the room.
It should be washed at least once every week during operation.

1. Remove the Air Filter from the front grill by pulling up.

2. Clean Air Filter with a vacuum cleaner or lukewarm, soapy water.

3. Shake it when clean to remove moisture completely. Replace it.

2. CLEANING THE AIR CONDITIONER

1. At least once a year, remove cabinet and thoroughly clean air conditioner. Have the unit inspected by an authorized

servicer to ensure unit is functioning properly.

2. Wash air conditioner with lukewarm, soapy water as needed. Rinse and dry thoroughly.

3. If using concentrated liquid detergent, dilute in warm water first.

4. Front grill may be wiped off with a cloth dampened in a mild detergent solution.

5. Cabinet may be washed with mild soap or detergent and lukewarm water, then polished with liquid wax for

appliances.

6. Condenser and Evaporator coils should be cleaned at the beginning of each cooling season. Use a soft brush or

vacuum cleaner to clean them, making sure that the Condenser and Evaporator coils are not damaged.

7. Do not use abrasive cleaners. These items scratch, crack and discolor surfaces.
