NOTES:
1. Boldface indicates a field-supplied drive is required. (See Note 6.)
2.
indicates field-supplied motor and drive are required.
3. Maximum usable watts input is 2120. Extensive motor and electrical
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 rat-
ings shown will not result in nuisance tripping or premature motor
failure. Unit warranty will not be affected. For additional information
on motor performance, refer to Table 4.

4. Values include losses for filters, unit casing, and wet coils.
5. Use of a field-supplied motor may affect wire sizing. Contact your
representative to verify.
6. Standard motor drive range: 1070 to 1460 rpm. All other rpms
require field-supplied drive.
7. To convert watts to bhp:
watts input x motor efficiency
bhp =
Motor efficiency = .84
