4. FUNCTION OF MAIN COMPONENTS

• FAN & COOLING CONTROL

The Fan Control Selector Switch has six positions.

Choose one of the speed settings by rotating the fan control Selector Switch to the appropriate position

OFF Select this setting for stop all operation of air conditioner

FAN Select this setting for low speed air circulation without cooling and

heating.

LOW COOL Select this setting for cooling operation with LOW FAN.

HIGH COOL Select this setting for cooling operation with HIGH FAN.

LOW HEAT Select this setting for Heating operation with LOW FAN.

HIGH HEAT Select this setting for Heating operation with HIGH FAN.

• TEMPERATURE CONTROL

Choose a temperature settings by rotating the knob of thermostat to the appropriate position

• 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.

• HEATER LAMP

When the unit sets heating operation condition, the red lamp is lighted.

When the frost settles on the heat exchanger of the outside, defrosting is made automatically and the red lamp is turned

off.

The unit may give a hiss and the fan motor stops for 1 to 10 minutes.

This should not be regarded as a problem.

After defrosting, the heating operation begins again.

NOTE

• ECONOMICAL AND COMFORTABLE USE

1. Properly control the room temperature.

2. Avoid being exposed to direct sunlight.

3. Prevent the wind from entering the room.

CAUTION

When the air conditioner has been performing its cooling operation and is turned “OFF”or set to the ‘FAN”

position, wait at least 3 minutes before resetting to the cooling operation.

•MOTOR

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

•FAN MOTOR

–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.

* Heating condition is in opposition.

•CAPACITOR

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

•ACCUMULATOR

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

CAUTION

In order to After Service convenience that the motor is common parts with Cooling only model, (This part is not

use of medium speed function so that the lead wire’s receptacle is taping)

Because of the motor supplies of having a lead wire’s receptacle when Heat Pump model’s After Service that it

is necessary to taping of lead-wire.

5. GENERAL INFORMATIONS

•CHANGING AIR FLOW DIRECTION

Air flow deflectors divert air from center flow to left or right and up or down.

Adjust deflectors for desired air flow pattern.

•AIR FLOW AROUND UNIT

Check indoor grille 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.

•DRAIN HOLE AND WATER DRIPPING OUTSIDE

Locate drain hole at the rear or on the bottom 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 tilted 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.

•HOW TO INSTALL THE DRAIN CAP

This drain cap is not attached the rear the unit at the factory.

If you want to install the drain cap, please install the drain

cap like Fig. of the drain cap.

There are two kinds of method to install the drain cap.

The first method is that the shape of hole like

It is good for the household.

The second method is that the shape of hole is like

It is good for the shop.

•DOOR VENT

The door vent for the room air ventilation is lever type.

If the door vent lever moves to the left, then close the

vent and moves to the rght, then open the vent.

M4x8 SCREW: Use Screw(M4x8) only.

•HOW TO ATTACH CABINET DRAIN

The air conditioner employs a proper drain method whereby the condensed water (moisture removed from the air) is

drained to the outside.

In very humid weather, excessive condensate water removed from the air may cause some water to collect. To remove

this excess water you can install the cabinet drain as detailed below.

1. Take the cabinet drain which is located in the upper styrofoam pad.

2. Remove the hole rubber from the base pan bottom hole.

3. Install the cabinet drain to the left corner of the cabinet with 3 screws.

4. Connect the drain hose to the outlet located at the bottom of the cabinet drain.

You can purchase the drain hose or tubing locally to satisfy your particular needs.

(Drain hose is not supplied)

CAUTION

1. Remove “the Grille Front”from the unit.

2. Find “the Cabinet Drain”which is attached on rear side of “the Grille Front”.

- If you don’t remove it. the unit cannot be operated normally.

3. Assemble “the Cabinet Drain”according to the instruction of page 5

- “How to attach cabinet drain”

6. CARE AND MAINTENANCE

•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 grille by pulling to right.

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

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

•CLEANING THE AIR CONDITIONER

1. At least once a year, remove cabinet and thoroughly clean air conditioner.

Have the unit inspected by an authorized service man to ensure unit is

functioning properly.

2. Wash air conditioner with lukewarm, soapy water as needed.

Rinse and dry thoroghly.

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

4. Front grille 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 scrach, crack and discolor surfaces.

CAUTION

To avoid death of personal injury due to electrical shock, turn fan control OFF and unplug

power cord before cleaning or performing maintenance. After cleaning or performing

maintenance, reconnect power.

NOTE

A dirty Air Filter reduces air flow and the cooling capacity.

Do not operate unit without Air Filter.

NOTE

To assure continued peak efficiency, condenser coils (weather side of unit) should be checked periodically and

cleaned if clogged with soot or dirt from the atmosphere.

7. ELECTRICAL REQUIREMENTS

•ELECTRICAL GROUNDING INSTRUCTIONS

This appliance is equipped with a three-prong(grounding) plug for protection against possible shock hazards. If a two-prong

wall receptacle is encountered, the customer is required to contact a qualified electrician and have the two-prong wall

receptacle replaced with a properly grounded three-prong wall receptacle in accordance with the National Electrical Code.

•USE OF EXTENSION CORD

Because of potential safety hazards under a certain condition 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 (MIN.)

The socket-outlet shall be installed near the equipment and shall be easily accessible.

•REPLACEMENT OF SUPPLY FLEXIBLE CORD.

It the supply flexible cord is damaged, it must be replaced by the manufacturer or its service agent or similarly qualified

person in order to avoid a hazard.
