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 1000. 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. Alternate motor drive range: 760 to 1090 rpm. All other rpms require
field-supplied drive.
