3. Slide the new RO element (figure 3, item 10) into the high pressure vessel (figure 3, item 2) until the brine
seal (figure 3, item 12) is approximately 4 inches (102 mm) past the inside lip.
4. Lightly lubricate four new O-rings (figure 3, item 9) and two new O-rings on each end plug (figure 3, item 4).
5. Push each end plug (figure 3, item 4) into the high pressure vessel (figure 3, item 2), ensuring that the high
pressure ports and the product water port on the RO membrane (figure 3, item 10) are aligned with their
respective holes in the high pressure vessel.
6. Continue to push each end plug (figure 3, item 4) into the high pressure vessel (figure 3, item 2) until the
segmented ring groves are exposed at each end of the high pressure vessel.
7. Verify that the high pressure ports and the product water port are still aligned with their respective holes in the
high pressure vessel (figure 3, item 2).
8. Lightly lubricate two new O-rings (figure 3, item 8) with silicone lubricant, and install an O-ring on each high
pressure fitting (figure 3, item 7).
9. Install a high pressure fitting (figure 3, item 7) with new O-rings (figure 3, item 8) in the high pressure ports at
each end of the high pressure vessel (figure 3, item 2), and secure each in place with a high pressure fitting
retainer (figure 3, item 6)
10 Wrap the male threads of the product water fitting (figure 3, item 1) with three layers of anti-seizing tape.
11. Install the product water fitting (figure 3, item 1) on the high pressure vessel (figure 3, item 2). Tighten until
two or three threads are exposed from the end plug (figure 3, item 4). Use no tools, and do not over tighten.
12. Install a three piece segment ring (figure 3, item 5) in each end of the high pressure vessel (figure 3, item 2)
and secure each of the six segments in place with three allen head screws (figure 3, item 3) at each end.
13. Perform the High Pressure Vessel Subassembly Replacement Installation procedure in this work package.
