Maintenance
16. High Pressure Hose: The High Pressure Hose
has been assembled with crimp fittings
by Sea Recovery. The High Pressure Hose is
NOT repairable. Should a leak, damage, or
failure develop order a replacement hose
from Sea Recovery.
17. Reverse Osmosis Membrane and Pressure
Vessel Assembly:
NOTE : The System Membrane Element
is accessible with the Vessel still attached
to the frame, provided there is sufficient
room to the left and right of the System to
remove the R.O. membrane element.
Replace all Brine and Product Water O-Rings
attached to the End Plugs within the High Pressure
Vessel Assembly each time the Reverse Osmosis
Membrane Element is removed or replaced.
Ensure these O-Rings are on hand prior to repair.
R.O. Membrane Elements are only installed
and removed from the INLET end of the High
Pressure Vessel.
Disassembly of the Reverse Osmosis
Membrane and Vessel Assembly:
In this section the number in brackets [#] refer
to the reference number in the illustration on the
opposite page (fig. 8b).
a) Disconnect the High Pressure Hose from each
end of the High Pressure Vessel Assembly.
b) Using a 5/16” Allen wrench remove the 3
each Socket Head Cap Screws #16 from the
three-piece Segment Rings [14] located at
each end of the Pressure Vessel.
c) Push inward on the End Plug [3 & 4] and
Remove the three-piece segment ring [14]
from one end, repeat for the other end.
d) Remove the Port Retainer [15] from each end.
e) Remove the High Pressure Port [5 & 9] from
each end.
f) Remove the product water tube [13] from the
product water tube fitting [12].
g) Remove the product water tube fitting [12]
and nipple [11] from the end plug.
h) Insert all three of the Socket Head Cap
Screws [16] finger tight back into the End
Plug [3 & 4]. These screws are used as a grip
to remove the End Plug.
i) Grasp one or more of the Socket Head Cap
Screws with a pair of pliers and pull slowly
outward to remove the End Plug. There is
some resistance due to the two Brine O-Rings
exerting friction against the Vessel wall. With
the End Plug removed from the High Pressure
Vessel, the Reverse Osmosis Membrane
Element is visible.
j) Remove and discard the brine O-ring [6] from
each of the End Plugs.
k) Remove and discard the Product Water O-ring
[7] from each of the End Plugs.
l) Clean the end plugs with a cloth and inspect
each for any sign of wear, cracks, or damage.
m) Sparingly, lightly, lubricate NEW Brine O-Ring
and new Product Water O-Ring.
n) Place the NEW Product Water O-Ring into the
product port inner O-Ring groove in each of
the End Plugs.
o) Place the NEW Brine O-Ring onto the outer
Brine O-Ring grooves of each of the End Plugs.
p)
CAUTION
: At each end of the Reverse
Osmosis Membrane Element is a Product
Water Tube approximately ¾ in. (1.9 cm)
diameter by 1 in. (2.5 cm) long. The outside
diameter surface of this product water tube is
a sealing surface, which isolates the Product
Water from the Feed Water. The surface of
the Product Water Tube must be scratch free.
Never use pliers or other grabbing tools on
the Product Water Tube. Do not drop the R.O.
membrane onto a hard surface as the Product
Water Tube may be damaged.
With your fingers grasp the Product Water
Tube attached to the R.O. membrane
element from the INLET end of the Pressure
Vessel and pull outward. If resistance is met
then cup the INLET end of the High Pressure
Vessel with one hand and shake downward
to dislodge the R.O. membrane element.
The R.O. membrane element may also be
pushed from the Outlet end of the vessel
towards the Inlet end.
