• SAFETY INSTRUCTIONS (CONTINUED)
The receptacle should be an individual branch circuit used only for this air conditioner. Be sure the electrical
service is adequate for the model air conditioner you have chosen. The complete electrical rating of your air
conditioner is stated on the name plate located at the unit’s side. Be sure the plug receptacle is close enough
for the power cord to reach it.
WARNING :
An extension cord should not be used with your air conditioner!
To minimize shock and fire hazards, proper grounding is important. For your safety and
protection,this air conditioner is equipped with a special three-prong grounding plug on the service cord.
WARNING :
Do not, under any circumstances, cut or remove the grounding prong on the plug. To do so will create a shock
hazard.
Your air conditioner must be plugged into a properly grounded and polarzied three prong receptacle. Do not
use an adapter plug. If the wall receptacle you intend to use will not accept a three-prong plug, or if you are not
sure the outlet is adequately grounded or protected by a fuse or circuit breaker, have a qualified electrician
install the proper oulet according to the National Electric Code and applicable local code.

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

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.
