5. Standard drive range is 571 to 779 rpm. All other rpms require
a field-supplied drive.
6. Maximum continuous bhp is 2.4. Extensive motor and electrical
testing on these units ensures that the full range of the motor
can be utilized with confidence. Using the fan motors up to the
ratings shown will not result in nuisance tripping or premature
motor failure. Unit warranty will not be affected.
7. Interpolation is permissible. Do not extrapolate.
