OPERATING INSTRUCTIONS

NOTE

• FOR MOST ECONOMICAL USE

1. Properly control the room temperature.

2. Avoid the unit being exposed to direct sunlight. Keep direct sunlight from the room.

3. Do not leave doors and windows open.

• 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.

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.

OFF

Select this setting for stop all operation of air conditioner

Select this setting for high air circulation without cooling.

Select this setting for quiet air circulation without cooling.

Select this setting for cooling operation with LOW FAN.

Select this setting for cooling operation with MEDIUM FAN.

Select this setting for cooling operation with HIGH FAN.

HIGH FAN

LOW FAN

LOW COOL

MED COOL

HIGH COOL

• TEMPERATURE CONTROL

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

NOTE

Setting the control at the coldest extreme of the temperature range will not cool the room any

faster. Usually the midpoint is a good starting position. If the room temperature is not satisfactory

after a reasonable period of time, adjust the temperature control to a lower or higher setting.

• The Thermostat automatically starts and stops cooling 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.

GENERAL INFORMATION

• 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.

AUTO SWING (DWC-100CS, DWC-121CS, DWA-122CS, DWA-150CS, DWA-151CS)

When the auto louver switch is turned to “ON” position, the vertical louvers

automatically move right and left.

AUTO SWING

Thus, you can obtain comfortable cooling.

The vertical louvers may be stopped at any position when the auto louver

switch is turned off.

ON / OFF

• AIR FLOW AROUND 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.

• 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

Install the drain cap like Fig. of the right side.

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

The rear side of the unit

The first method is that the shape of hole like

SEAL DRAIN

It is good for the household.

CARE AND MAINTENANCE

CAUTION

To avoid death or 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.

• 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 to right.

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

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

NOTE

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

Do not operate unit without Air Filter.

• 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 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 scrach, crack and discolor surfaces.

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.

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.

WARNING :

To avoid death, personal injury or properly damage due to electrical shock, this unit must be grounded.

Do not under any circumstances cut or remove the round grounding prong from the plug.

Do not use a two prong adapter.

• USE OF EXTENSION CORD

Because of potential safety hazards under 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 will be a UL

listed 3-wire grounding type appliance extension cord rated has a 3-blade grounding plug and a 3-slot receptacle

that will plug into the appliance. The marked rating of the extension cord should be 125V/13A minimum for

DWC-100C, DWC-100CS, DWC-121C, DWC-121CS and 250V/10A minimum for DWA-122C, DWA-122CS,

DWA-150C, DWA-150CS, DWA-151C, DWA-151CS.
