	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.
		3.	Maximum continuous bhp is 3.7 and the maximum continuous watts are 3313.
*Motor drive range: 860 to 1080 rpm. All other rpms require field-supplied drive.		4.		See page 60 for general fan performance notes.
