*Motor drive range: 760 to 1000 rpm. All other rpms require a field-
supplied drive.
1. Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
your fan motors up to the wattage ratings shown will not result in nui-
sance tripping or premature motor failure. Unit warranty will not be
affected. For additional information on motor performance, refer to
Indoor Fan Motor Performance table on page 61.
