Operating instructions

6) The fourth screw goes into the hole diagonally opposite. Turn it in.
7) Put the remaining screws in following the same crisscross pattern working from the ends toward the center.
When all the screws are in place they can be tightened down.
8) Start at the corner of the screw pattern and tighten that screw. Work the same pattern from the ends toward
the center and crisscrossing as each screw is tightened. Check that each valve disc moves smoothly before
replacing the spring and camshaft.
9) Replace spring.
10) Replace camshaft and motor.
11) Replace controller and wiring harnesses.
MAINTENANCE
IMPORTANT: Many of the maintenance procedures involve o-rings. When reassembling two parts with
an o-ring seal, care must be taken with the placement of the o-ring. To properly install o-rings, they
should be lightly lubricated with silicone. Place the o-ring over the part feature that will be inserted into
the hole. Do not start the assembly with the o-ring in the hole.
PREVENTIVE MAINTENANCE
Injector Screen and Injector
Inspect and clean brine tank and screen fi lter on end of brine pickup tube once a year or when sediment appears
in the bottom of the brine tank.
Clean injector screen and injector once a year.
1) Unplug the wall-mount transformer.
2) Remove cover. Shut off water supply or put bypass valve(s) into bypass position.
3) Relieve system and valve pressure by using a screwdriver to press valve disc #7 slightly open. The pressure
will escape quickly.
4) Using a T-50 torx driver (recommended), or large fl at blade screwdriver, remove injector screen and injector cap.
5) Clean injector screen using a fi ne brush. Flush under running water until clean.
6) Using a needle-nose pliers, pull injector straight out.
7) Flush water into the injector screen recess of the valve body to fl ush debris out through the injector recess.
8) Clean and fl ush the injector with water. Inspect for any debris in the venturi.
9) Lubricate the o-rings on the injector, injector cap and injector screen with silicone lubricant only!
10) Reinstall the injector, injector cap and injector screen. Be careful not to crimp or bend the o-rings.
CAUTION: Do not overtighten the plastic cap. Seat the cap lightly into position. Overtightening may
cause breakage of the plastic cap that may not be immediately evident.
11) Plug the wall-mount transformer into outlet; reset clock if necessary.
12) Slowly open water supply valve or return bypass valve(s) to the “service” position.
