IntelliFlo Installation and User’s Guide
Backwash Mode
When the Filter mode has detected that the differential pressure is at the “Clean Filter Pressure” the filter
must be cleaned. You need to stop IntelliFlo either by pressing the Backwash button or “Start/Stop” button.
IntelliFlo must now be run for a preset cycle time with a preset flow. The flow is adjustable to accommodate
the specific filter backwash flow requirement. After the backwash cycle, a rinse cycle, with preset duration
time will be executed. When the two cycles have been completed or if the Start/Stop button is pressed to
stop the process, the filter status will be recalculated and the zero-pressure measured when Filter mode is
operated again.
• Backwash is a essential mode for cleaning as well as maintaining the % Clean Filter menu
• Backwash mode tells the computer to recalculate the clean filter pressure and start a new cycle
• Backwash button doubles for Rinse in operation
• When using cartridge filters the backwash cycle must be performed when cleaning or replacing
filters. This helps the computer reset its 0 head pressure level
• If you are charging a DE system, charge the system first during a normal running cycle. After the
filter is charged, run the pump in backwash mode with the filter valve in the filter position to reset the
% clean filter status. Then run the pump in filter mode.
Note: IntelliFlo will ramp up to full speed if necessary to achieve the commanded flow. Be sure that
the system can withstand the resultant pressures.
