Bhp — Brake Horsepower Input to Fan

Watts — Input Watts to Motor

NOTES:

1.Boldface indicates field-supplied or alternate (as appropriate) drive is required. (See Note 7.)

2. indicates alternate motor and drive are required.

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

4.Maximum usable watts input is 2120 with standard motor and 2615 with alternate motor. Maximum continuous bhp is 2.40 with

standard motor and 2.90 with alternate motor. 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: 685 to 935 rpm. Alternate motor drive

range: 835 to 1085 rpm. All other rpms require field-supplied drive.

8.Interpolation is permissible. Do not extrapolate.
