ELLIPTIC VALVE REPLACE.
This task consists of:
General Mechanics Tool Kit (Appendix B, Section III, Item 4)
Tape, Anti-seize (Appendix C, Section II, Item 19)
Power shut down (Power Source Manual).
ROWPU Piping drained (TM 5-4610-241-10).
Chemical Cans removed (TM 5-4610-241-10).
There are four elliptic valves on the product water manifold. All are removed and
installed the same. One is shown, the others are similar.
Loosen clamp (1) and remove flexible tubing (2) from adapter (6).
Loosen clamp (3) and remove flexible tubing (4) from adapter (5).
Remove two adapters (5 and 6) from elliptic valve (7).
Remove elliptic valve (7) from nipple (8).
(5) As required, remove nipple (8) and hose clamps (1 and 3).
Be sure tape is wrapped in same direction as pipe threads.
Apply anti-seize tape to male pipe threads.
If removed, install nipple (8).
Install elliptic valve (7) on nipple (8).
Do not overtighten adapters as this may break the valves.
Install two adapters (6 and 5) on elliptic valve (7).
If removed, position clamps (1 and 3) on hoses (2 and 4).
