NOTES:
1. Boldface indicates a field-supplied drive is required. (See
Note 4.)
2. Maximum usable watts input is 1000. Extensive motor and elec-
trical testing on these units ensures that the full range of the motor
can be utilized with confidence. Using your fan motors up to the
wattage ratings shown will not result in nuisance tripping or pre-
mature motor failure. Unit warranty will not be affected. For ad-
ditional information on motor performance, refer to Table 4.
3. Values include losses for filters, unit casing, and wet coils.
4. Alternate motor drive range: 760 to 1090. All other rpms require
field-supplied drive.
5. To convert watts to bhp:
watts input x motor efficiency
bhp =
746
Motor efficiency = .75
