Bhp — Brake Horsepower Input to Fan

Watts — Input Watts to Motor

NOTES:

1.Boldface indicates field-supplied drive is required. (See Note 7.)

2. indicates alternate drive is required.

3. indicates field-supplied motor and drive are required.

4.Maximum usable watts input is 2120 and maximum continuous bhp is 2.40. Extensive motor and electrical testing on these units

ensures that the full range of the motor can be utilized with confidence. Using your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected.

5.Values include losses for filters, unit casing, and wet coils.

6.Use of a field-supplied motor may affect wire sizing. Contact your representative to verify.

7.Standard motor drive range: 590 to 840 rpm. Alternate motor drive

range: 685 to 935 rpm. All other rpms require field-supplied drive.

8.Interpolation is permissible. Do not extrapolate.
