NOTES:
1.
Boldface
indicates field-supplied drive required. (See Note 3.)
2. indicates field-supplied motor and drive required.
3. Motor drive range is 840 to 1085 rpm for standard 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 2.9 for standard 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 addi-
tional 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.

2. indicates field-supplied motor and drive required.
3. Motor drive range is 860 to 1080 rpm 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 4.2 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
