NOTES:
1.
Boldface
indicates a field-supplied drive is required. (See Note 6.)
2. indicates field-supplied motor and drive are required.
3. Maximum continuous bhp is 1.80 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. For additional information on motor perfor-
mance, refer to Evaporator-Fan Motor Data tables on pages 42 and 43.
4. Values include losses for filters, unit casing, and wet coils. See page 43 for
accessory/FIOP static pressure information.
5. Use of a field-supplied motor may affect wire sizing. Contact Bryant repre-
sentative to verify.
6. Motor drive range: 1020 to 1460 rpm for single-phase standard motors;
1120 to 1585 for 3-phase standard motors; and 1300 to 1685 rpm for high-
static motors. All other rpms require field-supplied drive.
7. Interpolation is permissible. Do not extrapolate.
