Flow Control and Filter Mode
The Filter Mode feature enables IntelliFlo to overcome head pressure loss to maintain the required fl ow.
The fl ow that the unit can provide is limited by the installed plumbing. If more fl ow is demanded than the
IntelliFlo can provide, it will ramp to full speed and create pressure.
