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 & 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.

3.1.2 PRESSURIZATION SUBSYSTEM
Proper pressure and proper flow across the
HRO Systems Membrane Element are two basic
requirements of Reverse Osmosis. Refer to
Section 2 for correct flow specifications and to
the Temperature Effect Chart in Section 12 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.
3.1.3 BRINE DISCHARGE SUBSYSTEM
This section of the System carries the Brine
Discharge expelled from the R.O. Membrane
Element back to the feed source.
34. Flow Meter, Brine Discharge Water measures
Brine Flow of the System and is located on the
left side of the dual port Brine/Product Water
Flow Meter. This is one of the most important
visual checkpoints of the HRO system and
should be monitored on a regular basis.
35. Clean/Rinse Outlet Valve (optional) is used in
conjunction with the Clean/Rinse Inlet Valve
to set the System Brine Discharge Line into a
normal, storage or cleaning mode.
36. Thru Hull Discharge Fitting ** should be
installed above water level for discharge of the
Brine Discharge Water from the System.
