5. Maximum continuous bhp is 1.2 for standard motor, 2.4 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 47 and 48 for additional information.
6. Use of a field-supplied motor may affect wire sizing. Contact your Carrier
representative to verify.
7. Interpolation is permissible. Do not extrapolate.
