Bhp — Brake Horsepower Input to Fan
NOTES:
1. Boldface indicates alternate drive is required. (See Note 6.)
2. indicates alternate motor and drive cannot be used.
3. Maximum continuous bhp is 5.25 with standard motor and 4.20
with alternate 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 war-
ranty 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. Standard motor drive range: 900 to 1260 rpm. Alternate motor drive
range: 860 to 1080 rpm. All other rpms require field-supplied drive.
7. Interpolation is permissible. Do not extrapolate.
