MAINTENANCE
IMPORTANT NOTE:
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.
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
To reduce the risk associated with property damage due to water leakage:
• Do not use a torch or other high temperature sources near fi lter system, cartridges, plastic fi ttings or plastic plumbing.
• On plastic fi ttings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic.
• Take care when using pliers or pipe wrenches to tighten plastic fi ttings, as damage may occur if over tightening occurs.
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.
