GENERAL FAN PERFORMANCE NOTES
1. Values include losses for filters, unit casing, and wet coils. See Fig. 38 and
Table 9 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 7 and 8 for additional information.
3. Use of a field-supplied motor may affect wire sizing. Contact your Bryant repre-
sentative to verify.
4. Interpolation is permissible. Do not extrapolate.
