GENERAL FAN PERFORMANCE NOTES

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 nui- sance tripping or premature motor failure. Unit warranty will not be affected. For additional information on motor performance, refer to Indoor Fan Motor Performance table on page 54.

2.Values include losses for filters, unit casing, and wet coils. See Accessory/FIOP Static Pressure tables on page 50 for accessory 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.
