NOTES:
1. Boldface indicates standard operating range.
2. All other numbers indicates field-supplied drive required.
3. Factory shipped motor drive range is 1323 to 1579 rpm. Other rpms
require a field-supplied drive.
4. Static pressure losses (i.e., economizer) must be added to exter-
nal static pressure before entering Fan Performance table. See
Table 7 for accessory/FIOP static pressure information.
5. Interpolation is permissible. Do not extrapolate.
6. Maximum continuous bhp is 10.2 for 208/230 and 575-v units and
11.8 for 460-v units. The maximum continuous watts are 9510 for
the 208/230 and 575-v units and 11,000 for the 460-v units. Ex-
tensive motor and drive testing on these units ensures that the full
horsepower range of the motor can be utilized with confidence.
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.
