Clean Filter Pressure Example
Pool fi lters work by trapping dirt. At startup, when a pool fi lter is still clean, it registers an internal
pressure known as “starting pressure.” As dirt builds up in the fi lter, internal pressure increases.
Eventually, the fi lter will need a) to be cleaned, or “backwashed”, to remove the dirt if it is a sand or
D.E. fi lter, or b) to have its cartridges cleaned or replaced if it is a cartridge fi lter. This cleaning should
be done when the fi lter’s internal pressure has reached between 0,6 and 0,7 bar above starting pressure.
NOTE:
“Clean Filter Pressure” is the increase in internal fi lter pressure (above starting pressure)
necessary to reach the target pressure at which you would like IntelliFlo to alert you that it is time
to backwash the fi lter, or clean/replace the fi lter cartridges.
In the example below, the internal pressure of the fi lter is 0,7 bar at startup when the fi lter is clean (starting
pressure). The “Clean Filter Pressure” is set to 0,6 bar.
Alert Status
Once the “Alert” is triggered, the yellow warning LED is lit and “Alert” is displayed on the screen. At this
point, IntelliFlo will stop managing fl ow, and will adjust speed to maintain 0,6 bar of head pressure. Note
the following:
The % clean fi lter pressure has reached 100% • (See “Filter Mode” on p. 14, and “To
set the Clean Filter Pressure” on p. 22).
If parameter is set to 0,6 bar, each increment of 10% on the display equals 0,1 bar •
on the fi lter.
The fi lter must be cleaned or backwashed to reduce the pressure. Even if the •
system has a cartridge fi lter, the IntelliFlo must be started in Backwash Mode with
a clean fi lter to reset the fault and “zero” the IntelliFlo’s fi lter status reading.
Note:
For a complete list of IntelliFlo alert warnings, refer to “Alert and Warning” on
page 59.
