GENERAL NOTES FOR FAN PERFORMANCE TABLES
1. 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. For additional information on motor performance, refer
to Indoor-Fan Motor Data table on page 89.
2. Values include losses for filters, unit casing, and wet coils. See
page 88 for accessory/FIOP static pressure information.
3. Use of a field-supplied motor may affect wire sizing. Contact your
Bryant representative for details.
4. Interpolation is permissible. Do not extrapolate.
