*Standard low-medium static motor drive range is 1002 to 1225 rpm. Al- ternate high static motor drive range is 1193 to 1458 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 8.7 for 208/230-v units and 9.5 for 460-v units. The maximum continuous watts are 7915 for the 208/230-v units and 8640 for the 460-v units. Extensive motor and drive testing on these units ensures 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 warranty will not be affected.

4.Deduct 0.2 in. wg static pressure for high heat units at or above 9000 cfm. Deduct 0.3 in. wg static pressure for high heat units at or above 10,000 cfm.
