important SAFETY INFORMATION Please read all instructions before servicing this equipment. Pay attention to all safety warnings and any other special notes highlighted in the manual. Safety markings are used frequently throughout this manual to designate a degree or level of seriousness and should not be ignored. WARNING indicates a potentially hazardous situation that if not avoided, could result in personal injury or death.
This packaged air conditioner is designed only for outdoor ground level installations and can be readily connected to the high static duct system of a home. This unit has been tested for capacity and efficiency in accordance with AHRI Standards and will provide many years of safe and dependable comfort, providing it is properly installed and maintained. Abuse, improper use, and/or improper maintenance can shorten the life of the appliance and create unsafe hazards.
SINGLE DUCT APPLICATION MULTIPLE DUCT APPLICATION Figure 2. Single & Multiple Duct Applications • Duct work should be attached directly to the unit flanges for horizontal applications. • For highly resistive duct systems it may be necessary to add an additional return air duct and or supply to achieve maximum performance and prevent coil icing and refrigerant flood back. • The air conditioning output of the system will not cool the home if air is lost to the outside through leaks in the duct system.
Return Duct 1. Assemble the collar by overlapping the two ends. NOTE: One end of the collar is slotted and the opposite end has two small holes. Position the end with small screw holes underneath the slotted end. 2. Fasten the collar ends with two self drilling sheet metal screws. 3. Position the collar over the unit opening. Align the four holes in the collar with the four dimples or holes (depending on unit model) in the panel. 4. Secure the collar to the rear panel using self drilling screws (10-16x.5).
Electrical Connections WARNING: Figure 5. Supply Damper Condensate Drainage A 3/4” condensate fitting extends out of the side of the unit (Figure 6). The drain trap, shipped in the electrical compartment, must be installed to prevent water from collecting inside the unit. 1. Thread the elbow provided with the unit into the drain connection until hand tight. 2. Connect the condensate tubing onto the fitting, forming a trap near the drain connection. 3.
• The unit requires both power and control circuit electrical connections. Refer to the wiring diagrams (Figure 10 (page 13) & Figure 11 (page 14)) for identification and location of unit field wiring interfaces. Make all electrical connections in accordance with all applicable codes and ordinances. • Overcurrent protection must be provided at the branch circuit distribution panel and sized as shown on the unit rating label and according to applicable local codes.

Heat / Cool Thermostat For the highest efficiency, the use of a 2-stage Heating/ Cooling thermostat is recommended. The heat/cool thermostat prevents simultaneous operation of the heating and cooling units and is equipped with an ON-AUTO fan mode that allows the home owner to operate the indoor blower when only air circulation is desired. Connect the red, yellow, green and brown/orange low voltage wires to the R or RC, Y, G, W or W2 (if applicable) terminals on the thermostat base.
1. With the system operating at steady-state, measure the liquid refrigerant pressure in psig at the service valve. 2. Measure the liquid refrigerant temperature (° F) at the service valve. 3. For the temperature measured, determine the required liquid refrigerant pressure from Table 5, (page 15), Table 6, (page 15), Table 7, (page 16) & Table 8, (page 16), Table 9, (page 17) & Table 10, (page 17) for 1.5, 2, 2.5, 3, 3.5, & 4 ton units. For 5 ton units see Figure 12 (page 18).
