1.These capacities are gross ratings. For net capacity, deduct 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. No Sensible Cooling Capacity
