(T ext continued from page 13) Unstable operation may occur when the gas valve and manifold assembly are forced out of position while connecting improperly-routed rigid gas piping to the gas valve. Use a backup wrench when making con- nection to avoid strain on, or distortion of, the gas control piping.

Alternate Power Entry 1. Remove knockouts in fixed compressor panel located on duct panel side of unit. 2. Route high-voltage leads into high-voltage terminal box. 3. Connect ground wire to green-yellow wire using field- supplied splice. 4. Connect power wires to unit high-voltage leads.
HEA T ANTICIP A TOR SETTING — The room thermostat heat anticipator must be properly adjusted to ensure proper heating performance. Set the heat anticipator , using an am- meter between the W and R terminals to determine the exact required setting. NOTE: For thermostat selection purposes, use 0.
a. Before lighting the unit for the first time, perform the following: If the gas supply pipe was not purged be- fore connecting the unit, it will be full of air . It is rec- ommended that the ground joint union be loosened, and the supply line be allowed to purge until the odor of gas is detected.

Measure Manifold Pressure (Propane Units) — The main burner orifices on a propane gas unit are sized for the unit rated input when the manifold pressure reading matches the level specified in T able 5. Proceed as follows to adjust gas input on a propane gas unit: 1.
HEA TING SEQUENCE OF OPERA TION — See Fig. 26-33 and unit wiring label. On a call for heating, terminal ‘ ‘W’ ’ of the thermostat is energized, starting the induced-draft motor . When the hall- ef fect sensor on the induced-draft motor senses that it has reached the required speed, the burner sequence begins.

Air Filter Never operate the unit without a suitable air filter in the return-air duct system. Always replace the filter with the same dimensional size and type as originally installed.
Combustion-Air Blower — Clean periodically to as- sure proper airflow and heating ef f iciency . Inspect blower wheel every fall and periodically during heating season. For the first heating season, inspect blower wheel bimonthly to determine proper cleaning frequency .
Condenser Coil, Evaporator Coil, and Conden- sate Drain Pan — Inspect the condenser coil, evapo- rator coil, and condensate drain pan at least once each year . Proper inspection and cleaning requires the removal of the unit top. See Unit T op Removal section on page 45.
TROUBLESHOOTING Cooling SYMPTOM 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 . Defective thermostat, contactor , transformer, or control relay Replace component.
Cooling (cont) SYMPTOM CAUSE REMEDY Integrated control motor (units 48SX048,060 208/230 v) IFM does not run. Blower wheel not secured to shaft Properly tighten blower wheel to shaft. Insuff icient voltage at motor Determine cause and correct. Power connectors not properly seated Connectors should snap easily; do not force.
LED T roubleshooting — Error Code SYMPTOM CAUSE REMEDY Hardware failure. (LED OFF) Loss of power to control module (IGC). Check 5 amp fuse on IGC, power to unit, 24-v circuit breaker , and transformer. Units without a 24-v circuit breaker have an internal overload in the 24-v trans- former .
