“Section D” System Schematic with Component Identification & Descriptions
14. Commercial Pre-Filter ***provides extended
periods between filter element changes. The
Commercial Pre-filter contains a filter element
with 50 square feet of filtering area. This filter
removes suspended solids 5 Microns and larger.
15.
Air Bleed allows the operator to purge the
Commercial Pre-Filter Housing of any air
introduced from the feed line.
16.
Low Pressure Gauge, Commercial Pre-Filter
Inlet provides visual indication of the pressure into
the Commercial Pre-filter Housing from the
Booster Pump.
17.
Oil/Water Separator Filter The separator
element separates oil and suspended solids from
the System Feed Water. Oil permanently destroys
the R.O. Membrane Element, therefore, it is
recommended that the user avoid operating the
Horizon Seafari in oily, polluted waters.
18.
Air Bleed Valve allows the operator to purge the
Oil Water Separator Filter Housing of any air and
collated oil introduced from the feed line.
19.
Low Pressure Gauge displays the Inlet Pressure to
the High Pressure Pump. The gauge assists the
operator in diagnosing the Sea Strainer, Booster
Pump, Plankton Filter Element, Commercial
Prefilter Element, and Oil/Water Separator
Element condition.
20.
Low Pressure Switch shuts the System off
automatically when a plugged filter element or
other condition causes a low flow situation. This
protects the High Pressure Pump, the R.O.
Membrane Element and the Booster Pump from
damage.

B. PRESSURIZATION SUBSYSTEM:
Proper pressure and proper flow across the HROSystems
Membrane Element are two basic requirements of
Reverse Osmosis. Refer to Chapter B for correct flow
specifications and to the Temperature Effect Chart in
Section M of this Manual for temperature corrections.

25.
Electric Motor is directly coupled to the High
Pressure Pump. Single Phase Systems utilize
specially designed electric motors, which include a
thermal overload protection switch which shuts the
System off due to low voltage or over loading.
26.
High Pressure Pump is a marine quality, positive
displacement, ceramic plunger pump. The High
Pressure Pump lasts for years with proper use and
maintenance.
27.
High Pressure Hose, HP Pump Outlet MVA Inlet
transfers pressurized Sea Water from the High
Pressure Pump to the inlet of the R.O. Membrane
Element.
28 & 29.
R.O. Membrane Element & Vessel The
Membrane Element allows potable water molecules
to pass through while rejecting the salt ions. Only
about 10% of the System Feed Water becomes fresh
Product Water (per membrane element). The
remainder carries the rejected salt ions out of the
R.O. Membrane Element in a concentrated brine
stream.
31.
High Pressure Gauge displays the R.O. Membrane
Vessel outlet pressure.
32.
High Pressure Switch is used to automatically turn
the System off in case of over-pressurization during
operation.
33.
Back Pressure Regulator By turning the valve
adjustment handle clockwise and counterclockwise
pressure is increased and decreased accordingly.
This increases and decreases the production
capability of the R.O. Membrane Element.
