*Standard low-medium static motor drive range is 1066 to 1283 rpm. Al- ternate high static motor drive range is 1332 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.Fan performance is based on wet coils, clean ®lters, and casing losses.

4.Maximum continuous bhp is 10.2 for 208/230-v units and 11.8 for 460-v units. The maximum continuous watts are 9510 for the 208/ 230-v units and 11,000 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 prema- ture motor failure. Unit warranty will not be affected.

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