*Motor drive range is 1075 to 1455 rpm. All other rpms require a field-
supplied drive.
NOTES:
1. Boldface indicates field-supplied drive is required.
2. Values include losses for filters, unit casing, and wet coils. See

3. Maximum continuous bhp is 2.4 and maximum continuous watts
are 2120. Extensive motor and electrical testing on these units
ensures that the full range of the motor can be utilized with confi-
dence. Using your fan motors up to the wattage ratings shown will
not result in nuisance tripping or premature motor failure. Unit war-
ranty will not be affected. See Table 6 — Motor Data for additional
information.
4. Use of a field-supplied motor may affect wire sizing. Contact your
Carrier representative for details.
5. Interpolation is permissible. Do not extrapolate.
