indicates field-supplied motor and drive required.
3. Factory-shipped drive range is 15.50 to 20.08 r/s. Other r/s's may
require a field-supplied drive.
4. Values include losses for filters, unit casing, and wet coils.
5. Extensive motor and electrical testing on these units ensures that
the full range of the motor can be utilized with confidence. Using
