1.These capacities are gross ratings. For net capacity, determine the kW of the supply air blower motor from the SUPPLY AIR BLOWER PERFORMANCE Table, multiply this value by 3.415 MBH/kW to determine the motor heat, and deduct this heat from the gross capacity of the unit.

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

is 0.35kW. Refer to the SUPPLY AIR BLOWER PERFORMANCE Table for the kW of the supply air blower motor.
