3. INSTALLATION Awning 3.1 HOW TO INSTALL THE UNIT 1. To avoid vibration and noise, make sure the unit is installed securely and firmly. 2. Install the unit where the sunlight does not shine directly on the unit. If the unit receives direct sunlight, build an awning to shade the cabinet. 3. There should be no obstacle, like a fence, within 20" which might restrict heat radiation from the condenser. 4. To prevent reducing performance, install the unit so that louvers of the cabinet are not blocked. 5.
3.4 WINDOW REQUIREMENTS 1. These instructions are for a horizontal sliding or a casement window. 2. The electrical outlet must be within reach of the power cord. For installation in a casement window, the window frame assembly and the side of the building must be adequate to support the weight of the air conditioner. 21 1/2" min. 21"1 min. 40 /2" max. 15 1/2" min. 16 1/2" max. 15 1/2" min. Horizontal sliding window Casement window 3.
3.6 HORIZONTAL SLIDING WINDOW INSTALLATION Bolt 1. Loosely attach the support bracket to the bottom of bracket using bolts, washers, and nuts. Attach the leveling bolt and nut. (See Figure 22) Bracket Washer Nut Leveling Bolt & Nut Support Bracket Figure 22 2. Remove protective backing from window track seal and apply seal to window track. (See Figure 23) Window jamb Window Type ype C screw scre 11 8 /16" 3. Measure and lightly mark a line 8-1/4" from window jamb.
8. Slide curtain into curtain frame. Slide curtain frame assembly into side guides of the air conditioner cabinet. Make sure curtain is firmly enclosed on all sides by the frame. (See Figure 27) Curtain Frame Figure 27 Curtain 9. Cut side guide seal into 2 equal lengths. Remove protective backing and apply it to the rear side of cabinet side guides, starting just below curtain frame assembly. Pinch off excess length so seal is even with the bottom of side guide. (See Figure 28) 10.

TROUBLESHOOTING GUIDE 4.1 OUTSIDE DIMENSIONS Unit: mm(inchs) 368(14 1/2) 521(20 1/2) 607(23 3/5) 4.2 PIPING SYSTEM CONDENSER COIL FAN CAPILLARY TUBE MOTOR COMPRESSOR TURBO FAN EVAPORATOR COIL Following is a brief description of the important components and their functions in the refrigeration system. Refer to Fig. 31 to follow the refrigeration cycle and the flow of the refrigerant in the cooling cycle.
4.3 TROUBLESHOOTING GUIDE In general, possible trouble is classified in two kinds. 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/or improper application. Unit runs but poor cooling. Ineffective Cooling Check cold air circulation for smooth flow. Dirty indoor coil (Heat exchanger) Check outdoor coil (heat exchanger) & the fan operation. Check heat load increase.
Fails to Start Check power source. Check circuit breaker and fuse. Check control switch setting. Gas leakage of feeler bulb of thermostat Check control switch. Compressor only fails to start. Fan only fails to start. Improper wiring. Drop of power voltage. Improper thermostat setting. Defective of fan motor capacitor. Defective of compressor capacitor. Loose terminal connection. Capacitor check. Irregular motor resistance ( ). Irregular motor insulation ( ). Improper wiring.
ROOM AIR CONDITIONER VOLTAGE LIMITS NAME PLATE RATING MINIMUM MAXIMUM 115V ±10% 103.5V 126.5V COMPLAINT Fan motor will not run CAUSE REMEDY No power Check voltage at outlet. Correct if none. Power supply cord Check voltage to rotary switch. If none, check power supply cord. Replace cord if circuit is open. Rotary switch Check switch continuity. Refer to wiring diagram for terminal identification. Replace switch if defective. Wire disconnected or connection loose Connect wire.
COMPLAINT Compressor will not run, but fan motor runs. Compressor cycles on overload. Compressor cycles on overload. Compressor cycles on overload. Insufficient cooling or heating Excessive noise CAUSE REMEDY Thermostat Check the position of knob If not at the coldest setting, advance the knob to this setting and restart unit. Check continuity of the thermostat. Replace thermostat if circuit is open. Capacitor (Discharge capacitor before servicing.) Check the capacitor.
