Bhp — Brake Horsepower Input to Fan
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.
