Bhp	— Brake Horsepower Input to Fan												1. Boldface indicates field-supplied drive is required.
													2. Maximum usable watts input is 1000 and maximum continuous bhp is 1.00.

Watts — Input Watts to Motor 3. See page 60 for general fan performance notes.

*Motor drive range: 760 to 1000 rpm. All other rpms require field-supplied drive.
