*Standard low-medium static drive range is 1002 to 1151 rpm. Alternate
high-static drive range is 1193 to 1369. Other rpms require a field-
supplied drive.
Refer to page 189 for general Fan Performance Data notes.
NOTE: Maximum continuous bhp for the standard motor is 8.70 (for
208/230 and 575-v units) and 9.50 (for 460-v units). The maximum con-
tinuous watts is 7915 (for 208/230 and 575-v units) and 8640 (for 460-v
units). Do not adjust motor rpm such that motor maximum bhp and/or
watts is exceeded at the maximum operating cfm. See Evaporator Fan
Motor Performance table for more information.
