1. These capacities are gross ratings. For net capacity, deduct the air blower motor, MBh = 3.415 x kW. Refer to the appropriate blower
performance table for the kW of the supply air blower motor.
2. These ratings include the condenser fan motors (total 1 kW) and the compressor motors but not the supply air blower motor.
