Backwash Mode

When the pool filter's internal pressure reaches "Clean Filter Pressure," IntelliFlo displays a "Service
System Soon" alert on the control panel display (See "To set the Clean Filter Pressure" on page 26
and "Clean Fiter Pressure Example" on page 30.), indicating that the filter needs to be cleaned, or
"backwashed."
• Backwashing is essential for cleaning and maintaining the "% Clean Filter" menu (See "Filter
Mode" on
• Upon completing the backwashing cycle, IntelliFlo recalculates the clean filter pressure and starts
a new cycle
• The Backwash button operates both backwash and rinse portions of the backwashing cycle
• For cartridge filters, a backwashing cycle must be performed when cleaning or replacing filters.
IntelliFlo then resets the "Clean Filter Pressure" level
• If you are charging a DE system, first charge the system during a normal running cycle. Once 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.
A complete backwashing cycle includes a "backwash" phase and a "rinse" phase, and is accomplished
in Backwash Mode. At a press of the Backwash button, IntelliFlo will run in this mode at the flow rate
and for the length of time you programmed in the Backwash menu. At the end of this specified duration,
IntelliFlo will stop to give you the opportunity to reposition the filter valve to "Rinse" before beginning a
rinse cycle to complete the filter cleaning process. The backwash flow rate, backwash duration, and rinse
duration are programmed in the Backwash settings men. See
infomation on Backwash Mode setup. To operate Backwash Mode:
1. Ensure that the green power LED is on.
2. Press the Backwash button (LED is on). Press the Start/Stop button. IntelliFlo is now in
Backwash Mode and will operate at the flow rate and for the duration of time specified in the
Backwash settings menu.
3. The control panel screen in Backwash Mode will display a countdown of the time remaining in
the programmed duration of that function. By using the Up and Down arrow buttons, you can
switch between screens displaying the power usage in Watts (W), pump speed in RPM, and flow
rate.
