GENERAL FAN PERFORMANCE NOTES
1. Values include losses for filters, unit casing, and wet coils. See Table 31 and Fig. 44 for accessory/FIOP static pressure information.
2. Extensive motor and electrical 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 premature motor failure. Unit warranty will not be affected.
See Tables 9 and 10 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.
