*Motor drive range: 760 to 1000 rpm. All other rpms require field-
supplied drive.
NOTES:
1. Boldface indicates field-supplied drive is required.
2. Maximum usable watts input is 1000 and maximum continuous bhp
is 1.00. Extensive motor and electrical testing on these units

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.
