CAUTION This symbol indicates the possibility of injury or damage to property only. ■ Meanings of symbols used in this manual are as shown below.
Safety Precautions ■ Operation Do not place heavy object on the power cord and take care so that the cord should not be pressed. • There is danger of fire or electric shock. Do not share the outlet with other appliances. Take the power plug out if necessary, holding the head of the plug and do not touch it with wet hands. • It will cause electric shock or fire due to heat generation. • Otherwise, it may cause a fire or electrical shock.
Safety Precautions Do not operate or stop the unit by inserting or pulling out the power plug. • It will cause electric shock or fire due to heat generation. Do not damage or use an unspecified power cord. • It will cause electric shock or fire. Do not operate with wet hands or in damp environment. • It will cause electric shock.
Safety Precautions ■ Operation Do not put a pet or house plant where it will be exposed to direct air flow. • It may cause injury. Do not block the inlet or outlet of air flow. • It may cause product failure. Use a soft cloth to clean. Do not use wax, thinner, or a strong detergent. • The appearance of the air conditioner may deteriorate, change color, or develop surface flaws.

Disassembly Instructions Refrigerating Cycle CAUTION Discharge the refrigerant system using FreonTM Recovery System. If there is no valve to attach the recovery system, install one (such as a WATCO A-1) before venting the FreonTM. Leave the valve in place after servicing the system. 12. CONDENSER 1. Remove the cabinet. (Refer to section 2) 2. Remove the brace and the shroud cover. (Refer to section 4) 3. Remove the 5 screws which fasten the condenser. 4.
Disassembly Instructions NOTICE — Replacement of the refrigeration cycle. 1. When replacing the refrigeration cycle, be sure to discharge the refrigerant system using a FreonTM recovery System. If there is no valve to attach the recovery system, install one (such as a WATCO A-1) before venting the FreonTM. Leave the valve in place after servicing the system. 2. After discharging the unit completely, remove the desired component, and unbrace the pinch-off tubes. 3.
Disassembly Instructions Equipment needed: Vacuum pump, Charging cylinder, Manifold gauge, Brazing equipment. Pinch-off tool capable of making a vapor-proof seal, Leak detector, Tubing cutter, Hand Tools to remove components, Service valve.

Troubleshooting Guide Troubleshooting Guide Piping System CONDENSER COILS FAN CAPILLARY TUBE MOTOR COMPRESSOR TURBO FAN EVAPORATOR COILS : REFRIGERANT FLOW Following is a brief description of the important components and their functions in the refrigeration system. Refer to Fig. 18 to follow the refrigeration cycle and the flow of the refrigerant in the cooling cycle.
Troubleshooting Guide Troubleshooting Guide In general, possible trouble is classified in two causes. The one is called Starting Failure which is caused from an electrical defect, and the other is Ineffective Air Conditioning caused by a defect in the refrigeration circuit and improper application. Unit is running but cooling is ineffective Ineffective Cooling Check of cold air circulation for smooth flow. Check of outdoor coil (heat exchanger) & the fan operation.
Troubleshooting Guide Fails to Start Check of power source. Check of circuit breaker and fuse. Check of control switch setting. Gas leakage of feeler bulb of thermostat Check of control switch. Only compressor fails to start. Only fan fails to start. Improper wiring. Drop of power voltage. Improper thermostat setting Defect of fan motor capacitor. Defect of compressor capacitor. Loose terminal connection. Check capacitor. Irregular motor resistance ( ). Irregular motor insulation ( ).
Troubleshooting Guide COMPLAINT Fan motor will not run. CAUSE REMEDY No power Check voltage at outlet. Correct if none. Wire disconnected or connection loose Connect wire. Refer to wiring diagram for terminal identification. Repair or replace loose terminal. Capacitor (Discharge capacitor before testing.) Test capacitor. Replace if not within ±10% of manufacturer's rating. Replace if shorted, open, or damaged. Will not rotate Fan blade hitting shroud or blower wheel hitting scroll.
Troubleshooting Guide COMPLAINT Compressor will not run, but fan motor runs. CAUSE REMEDY Voltage Check voltage. See the limits on the preceding. page. If not within limits, call an electrician. Wiring Check the wire connections, if loose, repair or replace the terminal. If wires are off, refer to wiring diagram for identification, and replace. Check wire locations. If not per wiring diagram, correct. Capacitor (Discharge capacitor before servicing.) Check the capacitor.
Troubleshooting Guide COMPLAINT Compressor cycles on overload. Insufficient cooling or heating Excessive noise. CAUSE REMEDY Voltage Check the voltage. See the limits on the preceding page. If not within limits, call an electrician. Overload Check overload, if externally mounted. Replace if open. (If the compressor temperature is high, remove the overload, cool, and retest.) Fan motor If not running, determine the cause. Replace if required. Condenser air flow restriction Remove the cabinet.
