		LEGEND							NOTES:
Bhp	— Brake Horsepower Input to Fan								1. Boldface indicates field-supplied drive is required.
Watts	— Input Watts to Motor								2.			indicates alternate motor and drive are required.
*Standard motor drive range: 860 to 1080 rpm. Alternate motor drive range: 900 to 1260 rpm.									3. Maximum usable watts input is 3313 with standard motor and 4400 with alternate motor.
All other rpms require field-supplied drive.										Maximum continuous bhp is 3.70 with standard motor and 5.25 with alternate motor.
									4. See below for general fan performance notes.

GENERAL FAN PERFORMANCE NOTES

NOTES:

1.Values include losses for filters, unit casing, and wet coils. See page 61 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 table on page 63 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.
