Bhp Ð Brake Horsepower Input to Fan

NOTES:

1.Boldface indicates ®eld-supplied drive required. (See Note 2.)

2.Motor drive range is 760 to 1090 rpm. All other rpms require ®eld-supplied drive.

3.Values include losses for ®lters, unit casing, and wet coils.

4.Maximum continuous bhp is 1.2. Extensive motor and electrical testing on these units ensures that the full range of the motor can be utilized with con®dence.

Using your fan motors up to the ratings shown will not result in nuisance trip- ping or premature motor failure. Unit warranty will not be affected.

5.Use of a ®eld-supplied motor may affect wire sizing. Contact your local repre- sentative to verify.

6.Interpolation is permissible. Do not extrapolate.

7.Minimum allowable cfm is 300 cfm/ton.
