Introduction to the system
Cartridge Pre-Filters
Each system uses two 4x20” 5 micron filters as the final
stage of filtration before going to the Pearson Pump and
the seawater membranes.
There is a button on top of each housing to bleed air out
of the housing after changing filters. There are pressure
gauges on both the inlet and outlet to monitor pressure
drop across the filters. When the pressure drop across
the filters is 5 to 10psi (maximum) the filters should be
replaced.
Test Ports
There are product water test ports for each system so
the operator can confirm the produce quality. Note
that measuring the chlorine concentration should be
measured from the product tank as the chlorine injec-
tion point is too close to the sampling valve for ade-
quate mixing.
The black ABS
Drain Manifold is the drain for the
brine discharge and the back-wash from media filters.
This manifold is open (vented) at the top and it should
be noted that if the drain line outside the watermaker
is too small or is not graded properly that this vent pipe
may need to be extended through the top of the con-
tainer.
Carbon Block Filters
Product water from the storage tank needs to be pres-
surized and connects to the “Flush Water” port on the
outside of the container. The flush water goes through
Carbon block filters for removing chlorine from the
flush water to protect the membranes.
