1. These capacities are gross ratings. For net capacity, determine the kW of the supply air blower from the SUPPLY AIR BLOWER PERFORMANCE
Tables, 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 0.36kW. Refer to SUPPLY AIR BLOWER PERFORMANCE Tables for the kW of the supply air blower motor.
