4. Maximum continuous bhp is 1.20 for standard motor, 2.40 for high-static
motor. 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 additional information.
5. Use of a field-supplied motor may affect wire sizing. Contact your Bryant
representative to verify.
6. Interpolation is permissible. Do not extrapolate.
