THREE-WAY BALL VALVE (CHEMICAL FEED) 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 Source shutdown (TM 10-4610-241-10).
Chemical Can and Frame removed (TM 10-4610-241-10) .
There are four three-way ball valves mounted on the chemical feed pump
mounting plate. All are removed and installed the same. One is shown, the
others are similar.
Remove setscrew (1) and handle (2) from three-way ball valve (15).
To ensure correct installation and to prevent contamination of product water, be

Tag flexible tubes (3,4 and 5) and loosen three clamps (6,7, and 8). Remove flexible tubes.
Remove locknut (9) and valves from mounting plate (16).
Remove three adapters (10,11, and 12) and elbows (13 and 14) from three-way ball valve (15). As
required remove clamps (6,7 and 8) from flexible tubes (3,4 and 5).
Be sure tape is wrapped in same direction as pipe threads.
(1) Apply anti-seize tape to male pipe fittings.
(2) Install elbows (13 and 14) and three adapters (10, 11, and 12) on three-way ball valve (15).
(3) Position three-way ball valve (15) on mounting plate (16) and install locknut (9), handle (2), and setscrew (1).
(4) Position three clamps (6,7 and 8) on flexible tubing ( 3, 4 and 5).
