Insert the End Plug with new attached O-Rings into
the High Pressure Vessel while aligning the High
Pressure Port and Product Water Port to the
respective holes in the High Pressure Vessel.
Continue pushing inward on the End Plug until it’s
exposed end travels just past the Segment Ring
Groove in the Pressure Vessel. Ensure that the Ports
of the End Plug are aligned with the Port Holes of
the High Pressure Vessel.
Insert the High Pressure Port Fitting with attached
O-Rings into the High Pressure Port.
Replace the Port Retainer.
Clean the threads of the Product Water Port Nipple
and apply three wraps of new Teflon sealing tape to
the threads. Screw the Product Port Nipple into the
Product Port clockwise until only 2 or 3 threads are
exposed from the End Plug. Do not over tighten or
use a wrench.
Insert the three-piece Segment Ring Set into the
Segment Ring Groove of the High Pressure Vessel.
Align the Segment Ring Set with the tapped holes in
the End Plug for insertion of the three Socket Head
Cap Screws. Attach the three Socket Head Cap
Screws and tighten.
Reconnect the Plastic Product Water Tube. Screw
the hex nut clockwise finger tight.
Connect the High Pressure Hose to both the leading
end and discharge end of the High Pressure Vessel
Assembly. Do not over tighten the female swivel
nut.
15. High Pressure Switch [32]: The High Pressure
switch remains closed and keeps the system in
operation when high pressure is below 950 PSI (
±
50
psi). When the high pressure reaches 950 PSI (
±
50
psi) the High Pressure Switch shuts the System off.
The internal switching mechanism is very sensitive
and improper adjustment may damage the switch. In
field, adjustment of the High Pressure Switch is not
recommended.
If adjustment is absolutely necessary: Open fully the
Back Pressure Regulator [33]. Start the Horizon
Seafari system. Remove the sealing cap located on
the top of the pressure switch to expose the
calibration screw. Using a 3/16” hex wrench, gently
adjust the calibration screw, maximum 1/8th turn
(45 degrees) at a time. Turn the screw clockwise to
increase and counter clockwise to decrease as
appropriate.
Slowly increase operating pressure while observing
the High Pressure Gauge. The High Pressure
Switch should stop the system at 950 PSI (
±
50
PSI). If the system shuts off below 900 PSI or
above 1000 PSI, then repeat the adjustment
procedure and retest the set point. Once the High
Pressure Switch is properly set replace the
adjustment screw cover.
16.
High Pressure Gauge [31]: If the pressure gauge
fails to register, the orifice may be corroded with
debris. Use a thin wire to dislodge debris trapped
in the orifice.
17.
Back Pressure Regulator [33]: The Back Pressure
Regulator Stem does not require maintenance.
Should the O-Rings need replacement, remove the
control manifold from the end of the Membrane
Vessel Assembly. Carefully unscrew the High
Pressure Gauge [31] and remove the cover.
Remove the Flow Meter to access the Back
Pressure Regulator shaft. Use customary care when
replacing the O-Rings on the Back Pressure
Regulator shaft.
18.
Flow Meter [34 & 42]: Since the flow meter body
is clear, light penetrates it and supports biological
growth. To clean the flow meter body, remove the
top access fitting, the guide rod, float and O-Ring
bumpers and tube stops. Clean the interior of the
tube using a bottlebrush, soft rag, cotton swab or
other soft item. Reassemble the unit.
19.
Salinity Probe [41]: The salinity probe requires
cleaning once a year. To clean the probe, unscrew
the probe from its tee housing. Using a soft bristle
brush, scrub the probes to remove any built up
debris. Remove all old Teflon tape from the male
pipe threads of the Salinity Probe and clean the
threads before reinstalling hand tight only.
20.
Charcoal Filter [44]: A sulfurous (rotten egg)
smell from the product water requires the
replacement of the Charcoal Element. Otherwise,
the Charcoal Element should be replaced every 3 to
4 months. It is not cleanable.
