NOTES:
1. Values include losses for filters, unit casing, and wet coils. See
Table 7 for accessory/FIOP static pressure information.
2. 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 wattage ratings shown will not result in
nuisance tripping or premature motor failure. Unit warranty will not
be affected. For additional information on motor performance, refer
to Indoor-Fan Motor Performance, Table 6.
3. Use of a field-supplied motor may affect wire sizing. Contact your
Bryant representative for details.

*Motor drive range: 760 to 1000 rpm. All other rpms require field-
supplied drive.
NOTES:
1. Boldface indicates field-supplied drive is required.
2. indicates field-supplied motor and drive are required.
3. Maximum usable watts input is 1000 and maximum continuous
bhp is 1.00. Extensive motor and electrical testing on these units
ensures that the full range of the motor can be utilized with confi-
dence. Using your fan motors up to the wattage ratings shown will
not result in nuisance tripping or premature motor failure. Unit war-
ranty will not be affected. For additional information on motor per-
formance, refer to Indoor-Fan Motor Performance, Table 6.
4. Values include losses for filters, unit casing, and wet coils. See
Table 7 for accessory/FIOP static pressure information.
5. Use of a field-supplied motor may affect wire sizing. Contact your
Bryant representative for details.
6. Interpolation is permissible. Do not extrapolate.
