		LEGEND								NOTES:
Bhp	— Brake Horsepower Input to Fan									1. Boldface indicates field-supplied drive is required.
Watts	— Input Watts to Motor									2.		indicates field-supplied motor and drive are required.

*Motor drive range: 1070 to 1460 rpm. All other rpms require field-supplied drive.	3.	Maximum usable watts input is 2120 and maximum continuous bhp is 2.40.
	4.	See page 60 for general fan performance notes.
