Bhp Ð Brake Horsepower Input to Fan

NOTES:

1.Boldface indicates ®eld-supplied drive is required. (See Note 4.)

2. indicates ®eld-supplied motor and drive required.

3.indicates maximum usable bhp.

4.Motor drive range is 1020 to 1460 rpm. All other rpms require a ®eld- supplied drive.

5.Values include losses for ®lters, units casing, and wet coils.

6.Maximum continuous bhp is 1.8. Extensive motor and electrical test- ing 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 tripping or premature motor failure. Unit warranty will not be affected.

7.Use of a ®eld-supplied motor may affect wire sizing. Contact your lo- cal representative to verify.

8.Interpolation is permissible. Do not extrapolate.

9.Minimum allowable cfm is 300 cfm/ton.
