*Extensive motor and electrical testing on these units ensures that
the full horsepower and watts range of the motors can be used with
confidence. Using the fan motors up to the ratings shown in this table
will not result in nuisance tripping or premature motor failure. Unit
warranty will not be affected.

NOTES:
1. Boldface indicates a field-supplied drive is required. (See Note 6.)
2. indicates field-supplied motor and drive are required.
3. Maximum continuous bhp is 2.90. 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 rat-
ings shown will not result in nuisance tripping or premature motor
failure. Unit warranty will not be affected.
4. Values include losses for filters, unit casing, and wet coils.
5. Use of a field-supplied motor may affect wire sizing. Contact
Carrier representative to verify.
6. Motor drive range: 840 to 1085 rpm. All other rpms require field-
supplied drive.
7. Interpolation is permissible. Do not extrapolate.
