4. FUNCTION OF MAIN COMPONENTS
1. ROT ARY SWITCH (SELECTOR)
Please refer to the part of selector in the chapter 9 (Wiring Diagram). The rotary switch (selector) controls the fan motor’s rotation speed, and has six positions. The function of the six position is as follow.
• OFF: This position stops all operations of the air conditioner.
• HIGH COOL: This position provides the maximum air flow for rapid
cooling, dehumidifying and dust removing operations. (Use this position on sultry summer days.)
• MED COOL: This position provide the medium air flow for cooling dehumidifying and dust removing operations
• LOW COOL: This position provides the minimum air flow for quiet
cooling, dehumidifying operations. (Use this position on suitable for night-time.)
• HIGH FAN: This position provides the maximum air fiow alone fan
operation without cooling operation.
• LOW FAN: This position provides the minimum air flow air flow alone
fan operation without cooling operation.
2. THERMOST AT (TEMPERATURE CONTROL)
• 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.
3. MOTOR
The motor is used to rotate the indoor and outdoor fan so that the room air can be recirculated.
4. FAN
• BLOEWR 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. CAP ACIT OR
The Capacitor enlarges the difference of phase between main coil and sub coil so that the Compressor and Fan Motor starts well.
6. ACCUMULA T OR
The Accumulator blocks the unflow of liquid refrigerant and impurities into the Compressor.

5. GENERAL INFORMATIONS
1. 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.
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 two­prong wall receptacle is encountered, the customer is required to contact a qualified electrician and have the two­prong wall receptacle replaced with a properly grounded three-prong wall receptacle in accordance with the National Electrical Code.
4. USE OF EXTENSION CORDS
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 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 appliance.
5. DRAIN HOLE AND WATER DRIPPING OUTSIDE
Locate drain hole at the rear 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 tited or 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.
