The VFD parameters come with factory default set-
tings. The following parameter settings must be
changed. Settings can only be altered when the
pump motor is stopped.
To override the VFD parameters, turn the square rod
of the rotary disconnect switch inside the Controller
enclosure with a wrench clockwise to the ON posi-
tion. In order to be able to close the cover of the dis-
connect, the rod needs to be turned back to the OFF
position.
