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
ratings shown will not result in nuisance tripping or premature mo-
tor failure. Unit warranty will not be affected. For additional infor-
mation on motor performance, refer to Table on page 19.
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: 840 to 1085 rpm. All other rpms re-
quire field-supplied drive.
7. Interpolation is permissible. Do not extrapolate.
