Select the Best Location
1. To prevent vibration and noise, make sure the unit is installed securely and firmly. 2. Install the unit where the sun does not shine directly on the INSIDE unit. 3. The outside of the cabinet must extend outward for at least 12" and there should be no obstacles, such as a fence or wall, within 20" from the back of the cabinet because it will COOLED AIR prevent heat radiation of the condenser. Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner.

OUTSIDE AWNING

FENCE

HEAT RADIATION

CAUTION: All side louvers of the cabinet must
remain exposed on the outdside of the structure. 4. Install the unit slanted slightly so the back is slightly lower than the front (about 1/4"). This will force condensed water to the outside. 5. Install the unit with the bottom about 30"~60" above the floor level.

Window Requirements
NOTICE

INNER SILL

All supporting parts should be secured to firm wood, masonry, or metal.

1. This unit is designed for installation in standard double hung windows with actual opening widths of 22" to 36". The upper and lower sash must open sufficiently to allow a clear vertical opening of 13" from the bottom of the sash to the window stool. 2. If storm window presents interference, fasten a 2" wide wood strip to the inner window sill across the full width of the sill. The wood strip should be thick enough to raise the height of the window sill so that the unit can be installed without interference by the storm window frame. See Figure. 4. Top of wood strip should be approximately 3/4" higher than the storm window frame (STORM WINDOW FRAME) or wood strip (OUTDOORS) to help condensation to drain properly to the outside. 3. Install a second wood strip (approximately 6" long by 11/2" wide and same thickness as first strip) in the center of the outer sill flush against the back off the inner sill. This will raise the L bracket as shown Figure. 4. 4. If the distance between STORM WINDOW FRAME and WOOD STRIP MOUNTED ON TOP OF INNER SILL is more than 1", two of wood strip are not necessary.

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 unbraze the pinch-off tubes. 3. Solder service valves into the pinch-off tube ports, leaving the valves open. 4. Solder the pinch-off tubes with Service valves. 5. Evacuate as follows. 1) Connect the vacuum pump, as illustrated figure 25A. 2) Start the vacuum pump, slowly open manifold valves A and B with two full turns counterclockwise and leave the valves open. The vacuum pump is now pulling through valves A and B up to valve C by means of the manifold and entire system.

CAUTION: If high vacuum equipment is used, just crack valves A and B for a few minutes, then open slowly with the two full turns counterclockwise. This will keep oil from foaming and being drawn into the vacuum pump.
3) Operate the vacuum pump vaccum for 20 to 30 minutes, until 600 microns of vaccum is obtained. Close valves A and B, and observe vacuum gauge for a few minutes. A rise in pressure would indicate a possible leak or moisture remaining in the system. With valves A and B closed, stop the vacuum pump. 4) Remove the hose from the vacuum pump and place it on the charging cylinder. See figure 25B. Open valve C. Discharge the line at the manifold connection. 5) The system is now ready for final charging.

6. Recharge as follows : 1) Refrigeration cycle systems are charged from the High-side. If the total charge cannot be put in the High-side, the balance will be put in the suction line through the access valve which you installed as the system was opened. 2) Connect the charging cylinder as shown in figure 25B. With valve C open, discharge the hose at the manifold connection. 3) Open valve A and allow the proper charge to enter the system. Valve B is still closed. 4) If more charge is required, the high-side will not take it. Close valve A. 5) With the unit running, open valve B and add the balance of the charge. a. Do not add the liquid refrigerant to the Lowside. b. Watch the Low-side gauge; allow pressure to rise to 30 lbs. c. Turn off valve B and allow pressure to drop. d. Repeat steps b. and c. until the balance of the charge is in the system. 6) When satisfied the unit is operating correctly, use the pinch-off tool with the unit still running and clamp on to the pinch-off tube. Using a tube cutter, cut the pinch-off tube about 2 inches from the pinch-off tool. Use sil-fos braze and braze pinch-off tube closed. Turn off the unit, allow it to set for a while, and then test the leakage of the pinch-off connection.

COMPLAINT Fan motor will not run. No power Power supply cord Wire disconnected or connection loose Capacitor (Discharge capacitor before testing.) Will not rotate CAUSE REMEDY Check voltage at outlet. Correct if none. Check voltage to Control Box. If none, check power supply cord. Replace cord if circuit is open. Connect wire. Refer to wiring diagram for terminal identification. Repair or replace loose terminal. Test capacitor. Replace if not within ±10% of manufacturer's rating. Replace if shorted, open, or damaged. Fan blade hitting shroud or blower wheel hitting scroll. Realign assembly. Units using slinger ring for condenser fan must have 1 /4 to 5/16 inch clearance to the base. If it hits the base, shim up the bottom of the fan motor with mounting screw(s). Check fan motor bearings; if motor shaft will not rotate, replace the motor. Fan motor runs intermittently Revolves on overload. Check voltage. If not within limits, call an electrician. Test capacitor. Check bearings. Does the fan blade rotate freely? If not, replace fan motor. Pay attention to any change from high speed to low speed. If the speed does not change, replace the motor. Fan motor noise. Fan Turbo Loose clamper Worn bearings If cracked, out of balance, or partially missing, replace it. If cracked, out of balance, or partially missing, replace it. Tighten it. If knocking sounds continue when running or loose, replace the motor. If the motor hums or noise appears to be internal while running, replace motor. Check voltage. If not within limits, call an electrician. 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.

COMPLAINT Compressor will not run, but fan motor runs. CAUSE Thermistor REMEDY Check the TEMP control. If not at the lowest number, set TEMP control to this setting and restart the unit. Check the continuity of the thermistor. Replace the thermistor if the circuit is open. Check the capacitor. Replace if not within ±10% of manufacturers rating. Replace if shorted, open, or damaged. Check the compressor for open circuit or ground. If open or grounded, replace the compressor. Check the compressor overload, if externally mounted. Replace if open. (If the compressor temperature is high, remove the overload, cool it, and retest.) Check the voltage. If not within limits, call an electrician. Check overload, if externally mounted. Replace if open. (If the compressor temperature is high, remove the overload, cool, and retest.) If not running, determine the cause. Replace if required. Remove the cabinet. inspect the interior surface of the condenser; if restricted, clean carefully with a vacuum cleaner (do not damage fins) or brush. Clean the interior base before reassembling. If condenser fins are closed over a large area on the coil surface, head pressures will increase, causing the compressor to overload. Straighten the fins or replace the coil. Test capacitor. Check the terminals. If loose, repair or replace. Check the system for a restriction. If restricted, clean of replace. Close if open. Determine if the unit is properly sized for the area to be cooled. Check the set screw or clamp. If loose or missing, correct. If the turbo or fan is hitting air guide, rearrange the air handling parts. Remove the cabinet carefully and rearrange tubing not to contact cabinet, compressor, shroud, and barrier.
