OPERATION
FILTERING
Filtration starts as soon as flow is steady through the filter. As the filter removes dirt from the pool water, the
accumulated dirt causes a resistance to flow. As a result, the gauge pressure will rise and the flow will decrease. When
the pressure rises 7-10 psi (.49-.69 bar) above the starting pressure, or when the flow decreased below the desired
rate, clean or replace the filter cartridges. Once your filter is running and there is a pressure reading, line up the green
arrow with the current reading. When the pressure rises to or above the red or second arrow, it is time to clean your
filter.
REMOVING THE MANUAL AIR RELIEF VALVE
Your Filter comes with a Manual Air Relief Valve (MAR) pre-installed from the factory. Only qualified pool professionals
should service your filter’s Manual Air Relief Valve. For Qualified pool professionals only: If MAR valve needs to be
re-installed, follow this instruction carefully.
