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

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

DEFLECCIÓN
AUTOMÁTICA
automatically move right and left.
Thus, you can obtain comfortable cooling.
The vertical louvers may be stopped at any position when the auto louver switch is turned off.
ENCEN./APAG.
ON/OFF
• AUTO SWING
The switch of auto swing operating is linked with the power source.
ON: Air swing is operated while SELECTOR knob is set the COOL/HEAT or FAN position.
OFF: Stop the operation of air swing.
• 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

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”
Inside of Grille Front
Remove the Cabinet Drain
• 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.

6. CARE AND MAINTENANCE
• DWA-181CH/DWA-240CH-R/DWB-180CH-R/DWB-240CH-R
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.
• 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 up.
2. Clean Air Filter with a vacuum cleaner or lukewarm, soapy water.
3. Shake it when clean to remove moisture completely. Replace it.
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 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.
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.
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 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 AWG #12
The socket-outlet shall be installed near the equipment and shall be easily accessible.
WARNING :
To avoid death, personal injury or properly damage due to electrical shock, do not use an
extension cord or pinch the power cord.
Do not remove the warning tag from the power cord.
• 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.

8. DESCRITION OF FUNCTIONS
• COOLING OPERATION
If the rotary switch is turned to “COOL”, the unit starts to cooling operation.
The power is not supplied to the de-ice controller P.C.B(Deicer PCB) in this mode.
The fan motor is “ON” when rotary switch is turned to “COOL” because RL1(on the P.C.B) is normally close.
• HEATING OPERATION
If the rotary switch is turned to “HEAT”, the unit starts to heating operation.
The power is supplied to the de-ice controller P.C.B in this mode.
Fan motor, Reversing valve, Lamp, (Heater sump), these parts go on just turnning the rotary switch to “HEAT” because
RL1 is normally close.
The de-ice mode of heating operation is follows below.
• DE-ICE OPERATION
When the power is supplied by the turnning rotary switch to “HEAT”, the micro-computer chip(on the P.C.B) starts to
check the time and temperature.
Entering de-ice operation(to turn cooling cycle).
1. The micro-computer chip is check the temperature of condensor, After 50 minutes since the units starts on heating
mode.
2. If the Temperature is below -4˚C, RL1 goes on.
3. Then, all parts of concerning with RL1 go off also, such as Fan motor, Lamp, Reversing valve.
4. Now, the unit turned to cooling operation but fan motor is off.
Back to heat mode.
1. On the de-ice operation if the temperature is going over 15˚C, RL1 goes off.
2. Or 10minutes passed on the de-ice operation, RL1 goes off also.
3. Now the unit turned to heating mode because RL1 off means all parts turned on also.
such as Fan motor, Reversing valve, Lamp.
Remark : This de-ice operation is always repeat in heating mode when satisfying of the condition to enter the de-ice
operation.
