		LEGEND																NOTES:
Bhp	— Brake Horsepower Input to Fan																	1. Boldface indicates field-supplied drive is required.
																	2.						indicates field-supplied motor and drive are required.
Watts	— Input Watts to Motor
*Standard motor drive range: 590 to 840 rpm. Alternate motor drive																	3.			Maximum usable watts input is 2120 and maximum continuous
																				bhp is 2.40.
range: 685 to 935 rpm. All other rpms require field-supplied drive.
