Notes:

 1.

For standard evaporator fan speed (rpm), reference the standard motor and sheave/fan speed applicable table in the fan performance section. 

 2.

Data includes pressure drop due to standard filters and wet coils. No accessories or options are included in pressure drop data.

 3.

1-hp Fan Motor Heat (MBh) = 2.829 x Fan bhp+.4024. 3-hp Fan Motor Heat (MBh) = 2.900 x Fan bhp+.4750

 4.

Factory supplied motors, in commercial equipment, are definite purpose motors, specifically designed and tested to operate reliably and continuously 

at all cataloged conditions. Using the full horsepower range of our fan motors as shown in our tabular data will not result in nuisance tripping or 

premature motor failure. Our product's warranty will not be affected.
