4. FUNCTION OF MAIN COMPONENTS
1. POWER & FAN CONTROL
Please refer to the part of switch in the chapter 9(Wiring Diagram).
2. THERMOSTAT (TEMPERATURE CONTROL)
3. MOTOR
The motor is used to rotate the indoor and outdoor fan so that the room air can be recirculated.
4. FAN
• 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. CAPACITOR
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.
ON Select this setting to turn on the unit.
OFF Select this setting to turn off the unit.
HIGH Select this setting for maximum air circulation.
LOW Select this setting for quite air circulation.
• 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.

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 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.
3. 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.
4. USE OF EXTENSION CORDS (ONLY DWB-056C)
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 for Model DWB-056C.
5. USE OF LCDI OR AFCI POWER CORDS(ONLY DWC-056CL)
Testing:
CASE 1 : Lamp exists
1. Plug into power receptacle.
2. If light is not on, press “RESET” button, light should turn on.
3. Press “TEST” button, light must turn off.
4. Press “RESET” button again for use. Light should turn on.
Do not use of above test fails.
CASE 2 : Lamp not exist
1. Plug into power receptacle. Turn on Unit.
2a. If unit operates normally, press “TEST” button. Unit should trip.
Press “RESET” button again for use.
2b. If unit not operate, press “RESET” button for use. Unit should operate.
Do not use if above test fails.

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.
