GENERAL INSTRUCTIONS IMPORTANT The equipment covered in this manual is to be installed by trained, experienced service and installation technicians. All duct work, supply and return ducts, must be properly sized for the design air flow requirement of the equipment. ACCA is an excellent guide to proper sizing. All duct work or portions thereof not in the conditioned space should be properly insulated in order to both conserve energy and prevent condensation or moisture damage.

INSTALLATION TABLE 4 LOCATION GENERAL The unit must be located outside, or in a well ventilated area. It must not be in the space being heated or cooled. A sound absorbing material should be considered if the unit is to be installed in such a position or location that might cause transmission of sound or vibration to the living area or adjacent buildings.

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 is such a position that it may be easily reached for servicing and maintenance. D.
WIRING – MAIN POWER FIGURE 8 – LOW VOLTAGE WIRING 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.
START UP AND OPERATION THREE PHASE SCROLL COMPRESSOR START UP INFORMATION SEQUENCE OF OPERATION 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. compressor contactor starting the compressor and outdoor motor.
SERVICE AND TROUBLESHOOTING SERVICE HINTS FIGURE 9 FAN BLADE SETTING DIMENSIONS 1. Caution homeowner to maintain clean air filters at all times. Also, not to needlessly close off supply and return air registers. This reduces air flow through the system which shortens equipment service life as well as increasing operating costs. 2. Check all power fuses or circuit breakers to be sure that they are the correct rating. 3.
