***CLICK ON THE ICON NEXT TO THE INSTRUCTIONS AND PRINT OUT FOR EASIER USE***

1. Turn off water supply to valve. Next, cycle valve to backwash position, then to service. Now remove electrical plug from outlet.

2. Remove control box cover.

3. Disconnect the brine line from the injector housing to the brine valve (if your unit has timed brine tank fill).

4. Remove the two capscrews that hold the back plate to the valve.

5. Grasp the back plate on both sides and slowly pull end plug and piston assembly out of the valve body, (see Fig. 1)and lay aside.

6. Remove the seal first using the wire hook with the finger loop (see Fig.2).

7. The spacer tool (use only for removing the spacers) has three retractable pins, retained by a rubber ring, at one end; they are retracted or pushed out by pulling or pushing the center button the opposite end.

8. Insert the pin end of the spacer tool into the valve body with the pins retracted (button pulled back). Push the tool tight against the spacer and push the button in, (see Fig. 3). When the button is pushed in, the pins are pushed out to engage the 1/4 dia. holes in the spacer. Remove the tool from the valve body. The spacer will be on the end. Pull the center button back, the pins will be retracted and the spacer can be removed from the spacer tool.



9. Alternately remove the remaining seals and spacers in accordance with steps No. 6 and 8.

10. The last or end spacer odes not have any holes for the pins of the spacer tool to engage, therefore if the end spacer does not come out on the first try, try again using the wire hook with the finger loop.

11. To replace seals, spacers and end ring, use special tool with the brass sleeve on one end. This is a double-purpose tool., (See Fig. 4). The male end acts as a pilot to hold the spacers as they are pushed into the valve body and the brass female end is used to insert the seals into the valve body.

12. To restuff a valve body, first take the end ring (the plastic or brass ring without holes), then with your thumb press the button on the brass sleeve end, the large dia. inner portion is now exposed (See Fig. 4). Place the end ring on this pilot with the lip on the end ring facing the tool, and push the tool into the valve body bore until it bottoms. While the tool is in the valve body, take a seal and press it into the inside diameter of the exposed brass female end (See Fig. 5).

13. Remove the tool, turn it end for end and insert it into the valve body bore. While holding the large dia. of the tool, slide it all the way into the valve body bore until it bottoms, then push the center button to push the seal of the tool and leave it in place in the valve body (See Fig. 6).

14. Remove the tool from the valve body and push the center on the brass female end to expose the pilot on the opposite end. Place a spacer on this end and insert the spacer and tool into the valve.

15. While the tool is still in the valve, press another seal into the inside diameter of the exposed brass sleeve end.

16. Remove the stuffer, turn it end for end, and insert it into the valve body bore.

17. Alternately repeat steps No. 13 and 14 until all seals and spacers have been pushed into the valve (See valve cross section of your valve).

18. Place recommended silicone lubricant on the piston and inside the valve.

19. Hold the back plate with one hand and guide the piston into the valve body with the other hand, then grasp the back plate on both sides and slowly push the piston assembly and end plug assembly into the valve (See Fig. 1).

20. Replace the two PH screws to hold the back plate to the valve and tighten securely.

21. Connect the brine line form the injector housing to the brine valve (if your unit has timed brine tank fill).

22. Set the time of day dial to the correct time.

23. Replace the electrical plug in the outlet.

24. Turn on water supply.

25. Cycle control and check for proper function.

26. Check by-pass valve.

**IT IS PROBABLY ADVISEABLE TO CHANGE THE PISTON AT THE SAME TIME***
