NOTES:
1.
Boldface
indicates field-supplied drive required. (See Note 5.)
2. indicates field-supplied motor and drive are required.
3. Values include losses for filters, unit casing, and wet coils.
4. Use of a field-supplied motor may affect wire sizing. Contact
your Carrier representative to verify.
5. Standard drive range is 9.5 to 13.0 r/s. All other speeds require
a field-supplied drive.
6. Maximum continuous BkW is 1.79. Extensive motor and electri-
cal testing on these units ensures that the full range of the
motor can be utilized with confidence. Using the fan motors up
to the ratings shown will not result in nuisance tripping or pre-
mature motor failure. Unit warranty will not be affected.
7. Interpolation is permissible. Do not extrapolate.
