*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 the 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
confidence. Using your fan motors up to the wattage ratings shown
will not result in nuisance tripping or premature motor failure. Unit
warranty will not be affected. See Table 6 — Motor Data for addi-
tional 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.
