			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: 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.
