9.5.5 Pressure Filter Assembly with Electric Filter Clogging Indicator
The Electric Filter Clogging Indicator does not require regular general maintenance. The panel light will illuminate when the
clogging indicator senses a 98 psi differential pressure across the filter element. Installing a new filter element will eliminate
the clogged condition. Pushing the illuminated button will reset the indicator light.
NOTE: Higher flow rates will result in higher differential pressures. (Example: The clogging indicator may sense a 98
psi differential pressure at a flow rate of 34 gpm but not show a clogged condition when the flow rate is reduced to 10
gpm.
