Prefilter Replacement
The prefilter incorporated in your DIamond RO is designed
to remove particles from your incoming water source. It is
impossible to predict expected life. It is recommended that
the prefilter be replaced when the pressure differential
across the prefilter reaches 5 psig or if there are visible par-
ticles in the second position MPS cartridge. The pressure is
displayed on the pressure gauges located on the inside of
the DIamond RO right front door. The differential represents
the difference between the prefilter inlet and the prefilter out-
let. To replace the prefilter, ensure that all power and water
are disconnected from the unit.
1.
Remove the prefilter by first pressing the upper and
lower thumb buttons on the quick disconnects.
2.
Remove the prefilter by pulling the cartridge straight
out.
3.
Replace the prefilter by following the instructions
located in the “Prefilter Installation” section of this
manual.
