INSTALLATION LOCATION TYPICAL INSTALLATIONS GENERAL 1. ROOF MOUNTED – The unit is mounted on a sturdy base on the roof of the building. Return air to the unit is brought through a single return grille (grilles with built-in filters are best since they enable easy access for filter changing). Return air ducts are attached to the lower section of the front panel. Supply air is brought from the unit to attic duct work or to a furred down hall. Supply air duct is attached to the top of the front panel.

5. OTHER INSTALLATIONS – Many other installations are possible with the packaged air conditioner. No matter what the installation, always consider the following facts: A. Insure that the discharge air is not obstructed in any way so as to cause operation difficulties. B. The indoor coil drain pan is equipped with a coupling that must be piped through a condensate drain trap to a suitable drain. C. Always mount the unit in such a position that it may be easily reached for servicing and maintenance. D.
WIRING – MAIN POWER Refer to the unit rating plate for wire sizing information and maximum fuse size. Each outdoor unit is marked with a “Minimum Circuit Ampacity”. This means that the field wiring used must be sized to carry that amount of current. If field installed heaters are added to the basic unit, a second separate power supply circuit will be required. The heater rating plate located adjacent to the basic unit rating plate will show the appropriate circuit ampacity fuse size, etc.

START UP AND OPERATION THREE PHASE SCROLL COMPRESSOR START UP INFORMATION Scroll compressors, like several other types of compressors, will only compress in one rotational direction. Direction of rotation is not an issue with single phase compressors since they will always start and run in the proper direction. However, three phase compressors will rotate in either direction depending upon phasing of the power.
LOW PRESSURE SWITCH, BYPASS, AND LOCKOUT SEQUENCE ADJUSTMENTS NOTE: The low pressure switch is an optional control and the bypass and lockout sequence are part of the standard compressor control module. ADJUSTABLE DELAY-ON-MAKE AND DELAY-ON-BREAK TIMER If the low pressure switch opens for more that 120 seconds, the compressor contactor will de-energize and go into a soft lockout.
SERVICE AND TROUBLESHOOTING SERVICE HINTS FAN BLADE SETTINGS 1. Caution homeowner to maintain clean air filters at all times. Also, not to needlessly close off supply and return air registers. This reduces airflow through the system, which shortens equipment service life as well as increasing operating costs. Shown in Figure 10 are the correct fan blade setting dimensions for proper air delivery across the outdoor coil. 2.
• To connect: SUCTION AND DISCHARGE TUBE BRAZING Compliant Scroll compressors have copper plated steel suction and discharge tubes. These tubes are far more rugged and less prone to leaks than copper tubes used on other compressors. Due to different thermal properties of steel and copper, brazing procedures may have to be changed from those commonly used. • To disconnect: heat joint Areas 2 and 3 slowly and uniformly until braze material softens and the tube can be pulled out of suction fitting.

TROUBLESHOOTING GE ECM BLOWER MOTORS CAUTION: Disconnect power from unit before removing or replacing connectors, or servicing motor. To avoid electric shock from the motor’s capacitors, disconnect power and wait at least 5 minutes before opening motor. Symptom Cause/Procedure • Noisy blower or cabinet • Check for loose blower housing, panels, etc.
TROUBLESHOOTING GE ECM™ MOTORS CONT’D. Replacing ECM Control Module To replace the control module for the GE variable-speed indoor blower motor you need to take the following steps: 1. You MUST have the correct replacement module. The controls are factory programmed for specific operating modes. Even though they look alike, different modules may have completely different functionality. USING THE WRONG CONTROL MODULE VOIDS ALL PRODUCT WARRANTIES AND MAY PRODUCE UNEXPECTED RESULTS. 2.
