GENERAL NOTES FOR FAN PERFORMANCE DATA TABLES

1.Static pressure losses (i.e., EconoMi$er IV) must be added to external static pressure before entering Fan Performance table.

2.Interpolation is permissible. Do not extrapolate.

3.Fan performance is based on wet coils, clean filters, and casing losses. See Accessory/FIOP Static Pressure table on page 164.

4.Extensive motor and drive testing on these units ensures that the full horse- power and watts range of the motor can be utilized with confidence. Using fan motors up to the watts or bhp rating shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected.

5.Use of a field-supplied motor may affect wire sizing. Contact your Bryant representative for details.
