NOTES:
1. Boldface indicates field-supplied drive required. (See Note 3.)
2. indicates field-supplied motor and drive required.
3. Motor drive range is 1020 to 1460 rpm for single-phase standard motors,
1120 to 1585 for 3-phase standard motors, and 1300 to 1685 for high-static
motors. All other rpms require a field-supplied drive.
4. Values include losses for filters, unit casing, and wet coils. See page 40 for
accessory/FIOP static pressure information.
5. Maximum continuous bhp is 1.30 for single-phase standard motors, 2.40 for
3-phase standard motors, and 2.90 for high-static motors. 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 ratings
shown will not result in nuisance tripping or premature motor failure. Unit
warranty will not be affected. See Evaporator-Fan Motor Data tables on
pages 41 and 42 for additional information.
6. Use of a field-supplied motor may affect wire sizing. Contact your Bryant
representative to verify.
7. Interpolation is permissible. Do not extrapolate.
