INSTALL THE AIR CONDITIONER IN THE WINDOW a. Carefully lift the air conditioner and slide it into the open window. Make sure the bottom guide of the air conditioner drops into the notches of the L bracket. See Figure. 27. IMPORTANT : When the air conditioner drops into the L bracket, the air conditioner will be centered in window opening as shown in Figure. 28. b. While steadying the air conditioner, carefully bring the window sash down behind the upper guide of the air conditioner, as shown in Figure. 29. 4. SECURE THE GUIDE PANELS Extend the guide panels (TYPE F) to fill the window opening using 4 screws (TYPE B) to secure them, as shown in Figure. 30. 5. INSTALL THE SASH SEAL AND SASH LOCK a. Cut the sash seal (TYPE E) to the window width. Stuff the sash seal between the glass and the window to prevent air and insects from getting into the room, as shown in Figure. 30. b. Fasten the L bracket using a (TYPE A) screw, as shown in Figure. 30. 6. Window installation of room air conditioner is now completed. See ELECTRICAL DATA for attaching power cord to electrical outlet. 3.2.4 How to Secure the Drain pipe In humid weather, excess water may cause the BASE PAN to overflow. To drain the water, remove the DRAIN CAP and secure the DRAIN PIPE to the rear hole of the BASE PAN.

Close the guide panels. Keeping a firm grip on the air conditioner, raise the sash, and carefully tilt the air conditioner backward, draining any condensate water. Lift the air conditioner from the window and remove the sash seal from between the windows. 3.3 ELECTRICAL DATA Line Cord Plug Use Wall Receptacle Power Supply Do not under any circumstances cut or remove the grounding prong from the plug. Power supply cord with 3-prong grounding plug Standard 125V, 3-wire grounding receptacle rated 15A, 125V AC Use 15 AMP, time delay fuse, or circuit breaker. USE OF EXTENSION CORDS Because of potential safety hazards, we strongly discourage the use of an extension cord. However, if you wish to use an extension cord, use a CSA certified/UL-listed 3-wire (grounding) extension cord, rated 15A, 125V. 4.

The one is called Starting Failure which is caused by an electrical defect. 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 cold air circulation for smooth flow. Dirty indoor coil (heat exchanger) Check heat load increase. Clean condenser. Not on separate circuit Check inside gas pressure. Malfunction of fan. Clogging of air filter. Obstruction at air outlet. Replacement of unit if the unit is beyond repair. Check outdoor coil (heat exchanger) and fan operation. Check gas leakage. Repair gas leak. Remove obstruction. Adjust refrigerant charge. Replacement of compressor. Check clogging in refrigeration circuit. Repair clogging in refrigeration circuit. Satisfactory operation with temperature difference of inlet & outlet air; 55~59°F (13~15°C) Malfunction of compressor. —18— Fails to Start Improper thermistor setting Loose terminal connection Improper wiring Check of power source. Drop of power voltage. Capacitor check. Replacement. Check of control panel setting. Compressor fails only to start. Defect of compressor capacitor. Irregular motor insulation (.) Irregular motor resistance ...
