1These capacities are gross ratings. For net capacity, deduct supply air blower motor, MBh. Example: Refer to the appropriate Blower Performance Table for the BHP of the supply air blower motor, MBh = 3.415 x kW and kW = BHP x 0.746 nameplate rated motor efficiency.

2These ratings include the condenser fan motors and the compressor motors but not the supply air blower motor.
