The capacities are gross ratings. For net capacity, deduct indoor blower motor, MBH=3.415 x kW. Refer to the appropriate Blower Perfor-
mance table for the kW of the supply air blower motor.
†
These ratings include the condenser fan motors (total 1 kW) and the compressor motors but not the supply air blower motor.
