	LEGEND	NOTES:
Bhp	— Brake Horsepower Input to Fan	1.		Boldface indicates field-supplied motor drive is required.
Watts	— Input Watts to Motor	2.			indicates field-supplied motor and drive are required.
*Motor drive range: 835 to 1185 rpm. All other rpms require field-supplied drive.		3.	Maximum usable watts input is 1000 and maximum continuous bhp is 1.00.
