III. STEP 3 — FIELD F ABRICA TE DUCTWORK Secure all ducts to building structure. Use flexible duct con- nectors between unit and ducts as required. Insulate and weath- erproof all external ductwork, joints, and roof openings with counter flashing and mastic in accordance with applicable codes.
VI. STEP 5 — MAKE ELECTRICAL CONNECTIONS A. Field Power Supply Unit is factory wired for voltage shown on nameplate. When installing units, provide a disconnect, per NEC (Na- tional Electrical Code) requirements, of adequate size (T able 2). All field wiring must comply with NEC and local requirements.

VII. STEP 7 — MAKE OUTDOOR-AIR INLET ADJUSTMENTS A. Manual Outdoor-Air Damper All units (except those equipped with a factory-installed econo- mizer) have a manual outdoor-air damper to provide venti- lation air . Damper can be preset to admit up to 25% outdoor air into return-air compartment.
VIII. STEP 8 — INST ALL OUTDOOR-AIR HOOD The same type of factory-installed hood is used on units with 25% air ventilation and units with an economizer . NOTE: The hood top panel, upper and lower filter retainers, hood drain pan, baf f le (size 300), and filter support bracket are secured opposite the condenser end of the unit.
NOTE: For maximum benefit of outdoor air , set the enthalpy control to the ‘‘A ’’ setting. At this setting, when the relative humidity is 50% and the outdoor air is below 74 F , the relay contacts on the sensor will be closed. 9. Reinstall economizer hoods if removed.
T ransformer (460-v Units Only) — On 460-v units, a trans- former is required. The transformer is provided with the ac- cessory and must be field-installed.

XIII. BASE UNIT OPERA TION A. Cooling, Units Without Economizer When thermostat calls for cooling, terminals G and Y1 are energized. The indoor (evaporator) fan contactor (IFC), and compressor contactor no. 1 (C1) are energized and evaporator- fan motor , compressor no.
III. EV APORA TOR F AN PERFORMANCE ADJUSTMENT (Fig. 25-27) Fan motor pulleys are factory set for speed shown in T able 1. T o change fan speeds: 1. Shut of f unit power supply . 2. a. Size 180 Only: Loosen belt by loosening fan motor mounting plate nuts.
4. Using jacking bolt under motor base, raise motor to top of slide and remove belt. Secure motor in this position by tightening the nuts on the carriage bolts. 5. Remove the belt drive. 6. Remove jacking bolt and tapped jacking bolt plate. 7. Remove the 2 screws that secure the motor mounting plate to the motor support channel.
T able 1 1 — Economizer Checkout Procedures TEST PROCEDURE RESUL TS A. Disconnect power at TR and TR1. Disconnect jumper between P and P1. See Fig. 15. B. Jumper TR to 1. C. Jumper T1 to T . D. Disconnect outdoor-air thermostat connections from S O and +.
Crankcase Heater Only the 559F300 unit is equipped with a 70-watt crankcase heater to prevent absorption of liquid refrigerant by oil in the crankcase when the compressor is idle. The crankcase heater is energized whenever there is a main power to the unit and the compressor is not energized.
TROUBLESHOOTING Refer to T able 13 for troubleshooting details. T able 13 — Cooling Service Analysis PROBLEM CAUSE REMEDY Compressor and condenser fan will not start. Power failure. Call power company . Fuse blown or circuit breaker tripped. Replace fuse or reset circuit breaker .
