LEGEND
NOTES:
1.
Boldface
indicates a field-supplied drive is required. (See Note 6.)
2. indicates a high-static motor and drive are required.
3. Maximum continuous bhp is 2.90 for standard motors; 4.20 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 prema-
ture motor failure. Unit warranty will not be affected. For additional informa-
tion on motor performance, 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. Standard motor drive range: 840 to 1085 rpm. High-static motor drive range:
860 to 1060 rpm. All other rpms require field-supplied drive.
7. Interpolation is permissible. Do not extrapolate.
