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.
