5. Maximum continuous bhp is 2.9 for standard 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 premature motor failure. Unit warranty will not be
affected. See Evaporator-Fan Motor Data tables on pages 41 and 42 for addi-
tional information.
6. Use of a field-supplied motor may affect wire sizing. Contact your Bryant
representative to verify.
7. Interpolation is permissible. Do not extrapolate.
