GENERAL FAN PERFORMANCE NOTES

NOTES:

1.Values include losses for filters, unit casing, and wet coils. See page 94 for accessory/factory-installed option 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 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. See Evaporator-Fan Motor Performance tables on pages 93 and 94 for additional 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.
