For Oversized Evaporator Fan Speed (RPM), reference
Fan motor heat (MBH) = 3.15 x Fan BHP.

Notes:
Data includes pressure drop due to standard filters and wet coils.
No accessories or options are included in pressure drop data.
5.03
Refer to Table 54 to determine additional static pressure
5.65
drop due to other options/accessories.
Factory supplied motors, in commercial equipment, are definite
6.34
purpose motors, specifically designed and tested to operate
7.08
reliably and continuously at all cataloged conditions. Using the
full horsepower range of our fan motors as shown in our tabular
7.89
data will not result in nuisance tripping or premature motor
—
failure. Our product's warranty will not be affected.
*For 380V/60 Hz units, the oversized motor is used as the
—
standard motor. Refer to "Motor & Sheave/Fan Speed" tables to
—
determine operating range.
