3. INSTALLATION 3.1 INSTALLATION REQUIREMENTS INSTALLATION HARDWARE If you use an existing wall sleeve, you should measure its dimensions. Install the new air conditioner according to these installation instructions to achieve the best performance. All wall sleeves used to mount the new air conditioner must be in good structural condition and have a compatible rear grille in order to securely attach the new air conditioner. (FIG.
3.2 INSTALLATION NOTE: All wall sleeves used to mount the new Air Conditioner must be in sound structural condition and have a compatible rear grille that securely attaches to sleeve, or rear flange that serves as a stop for the Air Conditioner. CAUTION We strongly recommend the removal of the old wall sleeve and the installation of a new FRIEDRICH USC Wall Sleeve. If you decide to keep the existing wall sleeve, you have to redirect the louvers at the back of the wall sleeve illustration.
3.3 PROCEDURE A 1 If you are using a new USC sleeve in conjunction with your unit, skip to step 3. Otherwise, install the plastic grille from the kit. Cut the plastic grille to fit the rear opening of the existing sleeve. Place the plastic grille to the inside of the wall sleeve at the rear flange. 4 Install the new unit into the wall sleeve. 5 To assemble trim, snap the tab of each piece into the slot of the other piece as shown below.
3.4 PROCEDURE B 1 4 Redirect the louvers at the back of the wall sleeve to 60° angle as shown in the FIG 25. The use of pliers is recommended. Remove the backing from the Horizontal Insulation strip 13/8 x 5/8 x 273/16 and attach that to the inside bottom of the sleeve as shown below. Remove the backing from the Around Insulation strip 13/8 x 3/4 x 611/2 and attach that to the inside front of the sleeve as shown below.
PROCEDURE B 8 To assemble trim, snap the tab of each piece into the slot of the other piece as shown below. Slide trim over the front of the air conditioner until trim is flush with sleeve as shown below. Trim (2 ea) Wall FIG. 31 CAUTION • Air conditioners covered in this manual pose an excessive weight hazard. Two or more people are needed to move and install the unit. To prevent injury or strain, use proper lifting and carrying techniques when moving unit.
3.5 PROCEDURE C 1 4 Redirect the louvers at the back of the wall sleeve to 60° angle as shown in the FIG 32. The use of pliers is recommended. Remove the backing from the Horizontal Insulation strip 13/8 x 13/8 x 273/16 and attach that to the inside bottom of the sleeve as shown below. Remove the backing from the Around Insulation strip 13/8 x 13/8 x 611/2 and attach that to the inside front of the sleeve as shown below.
PROCEDURE C 7 9 Remove the backing from the 13" shim strips and attach them as shown below in Fig. 39. The higher portion of shim is to be placed in front of the rib on the base of wall sleeve. 1" high To assemble trim, snap the tab of each piece into the slot of the other piece as shown below. Slide trim over the front of the air conditioner until trim is flush with sleeve as shown below. 3 /4" High FIG. 38 Trim (2 ea) Shim (2EA) Wall 6" 6" FIG.
3.4 ELECTRICAL REQUIREMENTS 3.4.1 ELECTRICAL DATA (FOR 115V MODEL) Line Cord Plug Do not under any circumstances cut or remove the grounding prong from the plug. Power supply cord with 3-prong grounding plug Use Wall Receptacle Parallel type Power Supply Use 15 AMP time delay fuse or 15 AMP circuit breaker. Standard 125V, 3-wire grounding receptacle rated 15A, 125V AC USE OF EXTENSION CORDS Because of potential safety hazards, we strongly discourage the use of an extension cord.

TROUBLESHOOTING GUIDE 4.1 OUTSIDE DIMENSIONS 24-21/32" (626mm) 14-13/32" (366mm) 19-21/32" (499mm) 4.2 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. 41 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 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 cold air circulation for smooth flow. Check outdoor coil (heat exchanger) & the fan operation. Dirty indoor coil (Heat exchanger) Check gas leakage.
Fails to Start Check power source. Check circuit breaker and fuse. Check control switch setting. Gas leakage at feeler bulb of thermostat Check control switch. Only compressor fails to start. Only fan fails to start. Improper wiring. Drop in power voltage. Improper thermostat setting Defect of fan motor capacitor. Defective compressor capacitor. Loose terminal connection. Check capacitor. Irregular motor resistance ( ). Irregular motor insulation ( ). Improper wiring Replacement.
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. Refer to wiring diagram for terminal identification. Repair or replace loose terminal.
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. Rotary Check for continuity, refer to the wiring diagram for terminal identification.
COMPLAINT Compressor cycles on overload. Insufficient cooling or heating Excessive noise. REMEDY CAUSE 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.
