Backwash Mode

When the pool fi lter'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 fi lter needs to be cleaned, or
"backwashed."
• Backwashing is essential for cleaning and maintaining the "% Clean Filter" menu (See "Filter
Mode" on page 19 for more information on fi
• Upon completing the backwashing cycle, IntelliFlo recalculates the clean fi lter pressure and starts
a new cycle
• The Backwash button operates both backwash and rinse portions of the backwashing cycle
• For cartridge fi lters, a backwashing cycle must be performed when cleaning or replacing fi lters.
IntelliFlo then resets the "Clean Filter Pressure" level
• If you are charging a DE system, fi rst charge the system during a normal running cycle. Once the
fi lter is charged, run the pump in backwash mode with the fi lter valve in the fi lter position to reset
the % clean fi lter status. Then run the pump in fi lter mode.
Note: IntelliFlo will ramp up to full speed if necessary to achieve the commanded fl ow. Be sure that the
