Reassemble motor into housing. Be sure setscrews are tightened on motor shaft flats and not on round part of shaft. g. Reinstall unit access panel. 4. Restore electrical power to unit. Start unit and check for proper blower rotation and motor speeds during heating and cooling cycles. D. OUTDOOR COIL, INDOOR COIL, AND CONDENSATE DRAIN PAN Inspect the outdoor coil, indoor coil, and condensate drain pan at least once each year. See Unit Top Removal section. The coils are easily cleaned when dry; therefore, inspect and clean the coils either before or after each cooling season. Remove all obstructions, including weeds and shrubs, that interfere with the airflow through the outdoor coil. Straighten bent fins with a fin comb. If coated with dirt or lint, clean the coils with a vacuum cleaner, using the soft brush attachment. Be careful not to bend the fins. If coated with oil or grease, clean the coils with a mild detergent-and-water solution. Rinse coils with clear water, using a garden hose. Be careful not to splash water on motors, insulation, wiring, or air filter(s). For best results, spray outdoor coil fins from inside to outside the unit. On units with an outer and inner (2 row) outdoor coil, be sure to clean between the coils. Be sure to flush all dirt and debris from the unit base. Inspect the drain pan and condensate drain line when inspecting the coils. Clean the drain pan and condensate drain by removing all foreign matter from the pan. Flush the pan and drain tube with clear water. Do not splash water on the insulation, motor, wiring, or air filter(s). If the drain tube is restricted, clear it with a “plumbers snake” or similar probe device. Ensure that the auxiliary drain port above the drain tube is also clear —27— TABLE 13H—SUPERHEAT CHARGING TABLE, UNIT 060 TEMP (F) AIR ENT COND EVAP AIR – CFM 1800 EVAP AIR – Ewb (F) 56 58 60 62 64 66 68 70 72 74 76 65 SPH 21.0 21.0 21.0 22.8 24.7 26.5 27.8 29.1 30.4 29.5 28.6 70 16.5 16.5 16.5 18.8 21.1 23.5 25.2 27.0 28.8 28.2 27.6 75 12.0 12.0 12.0 14.8 17.6 20.4 22.7 24.9 27.2 26.9 26.6 80 10.5 10.5 10.5 12.7 14.9 17.1 19.8 22.5 25.2 25.4 25.5 85 9.0 9.0 9.0 10.6 12.3 13.9 17.0 20.0 23.1 23.8 24.5 90 4.5 4.5 4.5 6.5 8.5 10.5 14.3 18.1 21.9 22.7 23.5 95 — — — — 4.8 7.2 11.7 16.2 20.7 21.6 22.5 100 — — — — — 3.6 8.6 13.6 18.6 20.0 21.4 105 — — — — — — 5.5 11.1 16.6 18.5 20.4 110 — — — — — — — 10.0 15.5 17.5 19.4 115 — — — — — — — 9.2 14.7 16.5 18.5 Ewb-Entering Wet Bulb SPH-Superheat at Compressor (F) – -Do not attempt to charge system under these conditions as refrigerant slugging may occur.

OUTDOOR FAN CAUTION: Keep the outdoor fan free from all obstructions to ensure proper cooling operation. Never place articles on top of the unit. Damage to unit may result. 1. Remove 2 screws at bottom of outdoor air intake grille and remove plastic grille. 2. Inspect the fan blades for cracks or bends. 3. If fan needs to be removed, loosen the setscrew and slide the fan off the motor shaft. 4. When replacing fan blade, position blade so that the leading edge is 2-in. back from outdoor inlet grille or 1/2-in. maximum fro fan deck (See Fig. 25). 5. Ensure that setscrew engages the flat area on the mot...
