Bhp — Brake Horsepower Input to Fan Watts — Input Watts to Motor

*Motor drive ranges: Low Range: 941-1176 High Range: 1014-1297

All other rpms require field-supplied drive.

Refer to this page for general Fan Performance Data notes.

NOTE: Maximum continuous bhp is:

Low Range: 8.63

High Range: 11.50

GENERAL NOTES FOR TABLES 5-22

1.Static pressure losses (i.e., EconoMi$er IV) from Table 26 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 Table 26 on page 30.

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

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