Bhp — Brake Horsepower

Watts — Input Watts to Motor

*Standard low-medium static drive range is 1066 to 1283 rpm. Alternate high- static drive range is 1332 to 1550. Other rpms require a field-supplied drive.

NOTE: Maximum continuous bhp is 10.20 (208/230 and 575 v) or 11.80 (460 v) and the maximum continuous watts are 9510 (208/230 and 575 v) or 11,000 (460 v). Do not adjust motor rpm such that motor maximum bhp and/or watts is exceeded at the maximum operating cfm. See Evaporator Fan Motor Performance table for more information.

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 191.

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 size. Contact your Bryant rep- resentative for details.
