*Standard low-medium static drive range is 891 to 1179 rpm. Alternate high static drive range is 1227 to 1550 rpm. Other rpms require a ®eld- supplied drive.

NOTES:

1.Static pressure losses (i.e., economizer) must be added to exter- nal static pressure before entering Fan Performance table. See Accessory/FIOP Static Pressure table on page 52 for more information.

2.Interpolation is permissible. Do not extrapolate.

3.Maximum continuous bhp is 4.25 and the maximum continuous watts are 3775. Extensive motor and drive testing on these units en- sures that the full horsepower range of the motor can be utilized with con®dence. Using your fan motors up to the watts rating shown will not result in nuisance tripping or premature motor failure. Unit war- ranty will not be affected.
