1.Refer to General Data Section for standard fan motor size on units.

2.FLA = FulL Load Amps

WSA = Wire Sizing Amps (Minimum supply circuit ampacity) MFCB = Maximum Fuse or Circuit Breaker Size

3.Amperage requirements are based on the rated max FLA current of each component in the unit. The rated max FLA current of the unit is not the sum total of all components, but is the total of the components which operate during maximum electrical load conditions.

4.The values in the chart are for power of the unit only.

5.Units are 3 phase, 60 cycle.

6.For units with other variations not listed above, consult factory engineering department for electrical requirements.
