*The static pressure must be addedto external static pressure. The sum and the indoor entering-air cfm should be used in conjunction with the Fan Performance
tables to determine indoor blower rpm and watts.

GENERAL FAN PERFORMANCE NOTES
1. Values include losses for filters, unit casing, and wet coils. See Table 13 and 14 and Fig. 46 for accessory/FIOP static pressure
information.
2. Extensive motor an d electrical testing on these units en sures 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 premature motor failure. Unit warranty will not be affected.
See Table 11 and 12 on this page for additional information.
3. Use of a field-supplied motor may affect wire sizing. Contact your Carrier representative to verify.
4. Interpolation is permissible. Do not extrapolate.
5. Performance includes clean filter and wet coil.
