cases. When using a VFD to operate the blower at this frequency, refer to the
nameplate for limits on vacuum and pressure, current draw and motor
performance.
If your specific model number is not listed above, please consult the nameplate
on the unit for electrical data. If the model you are installing is listed above,
please confirm the data on the nameplate. Data in Tables 1 through 4 is subject
to change and is approximate. Be sure to confirm necessary operating data what
that on the nameplate before commissioning the unit.
CAUTION! Do not operate any 3BA blower above 87 Hz without
consultation with the factory. Failure of the blower motor is possible when
operating out of range. Consult with the factory for assistance.
