Notes:
1. For Direct Drive Evaporator Fan Speed (rpm), reference Table 8, p. 9 .
2. Data includes pressure drop due to standard filters and wet coils.
3. Refer to Table 11, p. 9 to determine additional static pressure drop due to other options/accessories.
4. Direct Drive Fan Motor Heat (MBH) = 2.8623xFan BHP -0.1504
5. 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.
