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, 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 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. 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.
