	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: 760 to 1000 rpm. All other rpms require field-supplied drive.										3. Maximum usable watts input is 1000 and maximum continuous bhp is 1.00.
