Clean Filter Pressure Example
The following example shows the “Clean Filter Pressure” set to 14 PSI.
Pump newly installed and
system run for the first
time
Alert Status
Once the “Alert” is triggered the yellow warning LED is lit and “Alert” is displayed on
the screen. The pump will reduce speed to maintain 14 PSI of head pressure and stop
managing flow. Note the following:
• The % clean filter pressure has reached 100%.
• If parameter is set to 14 PSI every 10% on the display is 1.4 psi on the filter.
• If the parameter is set to 10 PSI every 10% on the display is 1 psi on the filter.
• The filter must be cleaned or backwashed to reduce the pressure. Even if the
system has a cartridge filter the IntelliFlo must be started in Backwash Mode
with a clean filter to reset the fault and "zero" the IntelliFlo's filter status reading.
Note: For a complete list of IntelliFlo alert warnings, refer to “Alert and
Warning” on page 49.
