If an economizer is installed, check the unit operating 

balance with the economizer at full outside air and at 

minimum outside air.

High stage airflow setting to be between 300 and 500 CFM 

per ton. For models with electric heat the total airflow must 

not be less than that required for operation of the electric 

heaters. See Appendix D for minimum airflow for specific 

electric heaters. 

NOTE: Never run CFM below 300 CFM per ton, 

evaporator freezing or poor unit performance is 

possible.

Standard Static Drive Motor

Adjust the CFM for the unit by changing the position of 

the low voltage leads on the terminal block TB1. Refer to 

Appendix A for blower performance at each speed tap 

 

NOTE: If more than one lead is energized 

simultaneously, the motor will run at the higher 

speed tap.

Standard Static Drive Motors are set up to use motor 

speed taps T1-T5  Refer to Appendix A for blower 

performance at each speed tap.

Fan speed for G (Fan) is fixed at TB-1-T1 and cannot be 

moved.

Low Cool Y1, Yellow (YL) is movable and set to TB1-T1.  

Low Heat W1, White (WH) is movable and set to TB1-T2.

These wires can be moved together or separately and 

placed on any unoccupied terminal.

NOTE: On units with DDC controls installed, 

refer to the DDC User Manual for details on 

making airflow adjustments. Individual settings 

are available for Fan Only, Low Stage Cooling, 

High Stage Cooling, Low Stage Heating, and High 

Stage heating which can be adjusted as needed to 

meet airflow requirements.

Refrigeration System Checks

This unit is equipped with  thermal expansion valves. 

Ensure the hold-down bolts on the compressor are secure 

and have not vibrated loose during shipment. Check that 

the vibration grommets have been installed and visually 

check all piping for damage and leaks and repair if 

necessary. The entire system has been factory charged 

and tested, making it unnecessary to field charge. Factory 

refrigerant charge is shown on the unit’s nameplate.

To confirm charge levels or, if a leak occurs and charge 

needs to be added to the system, it is recommended to 

evacuate the system and recharge refrigerant to the units 

nameplate specifications. This unit has been rated in the 

cooling mode at the AHRI rated conditions of indoor (80°F 

db / 67°F wb) and outdoor (95°F db). While operating at 

this condition the superheat and subcool should range 

as shown in the superheat and subcool table. Superheat 

should be measured at the suction service port located 

near the compressor. Subcool should be measured at the 

liquid line service port.
