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 bo om of the brine tank.
Clean injector screen and injector once a year:
1. Unplug the wall-mount transformer.
2. Shut off water supply or put bypass valve(s) into
bypass position.
3. Relieve system pressure by opening valve No. 7
(at rear) with a screwdriver (Figure 11).
4. Using a screwdriver, remove injector screen and
injector cap (Figure 14).
5. Clean screen using a fi ne brush. Flush 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.
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.
IMPORTANT: 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.
Water Meter Maintenance
Note: A water meter is used only with the 460i control.
If you are using the 440i control, this section does not
pertain to your conditioner.
The metering device used with the 460i demand control
may require simple maintenance. In rare instances,
the turbine wheel of the water meter can collect small
particles of oxidized iron, eventually preventing the wheel
from turning.
1. Shut off the water supply or put the bypass valve(s)
into the bypass position.
2. Relieve pressure by opening the Backwash Drain
Valve (the seventh back from the control) with a
screwdriver (Figure 11).
3. Loosen and remove the pipe/tube adapters or 1265
bypass from the inlet and outlet of the valve body.
4. Using a needle-nose pliers, remove the turbine from
the outlet housing. Grasp one of the four vanes of the
outer gland and pull straight out to remove turbine
assembly from the outlet of the valve (Figure 14).
5. Carefully remove the turbine wheel from the housing.
Use a toothbrush to lightly scrub the iron off the
magnet. Iron buildup on the surfaces can be removed
by soaking the wheel in a mild sodium hydrosulfi te
(such as RoVer*) solution for a few minutes. Flush
thoroughly with water.
6. Carefully reinstall the turbine wheel into the turbine
cage housing. Make sure that the sha of the wheel
seats into the bearing of the cage. Reassemble the
turbine cage and check that the wheel rotates freely.
7. Reinstall the turbine cage into the outlet of the valve.
8. Reinstall the pipe/tube adapters or 1265 bypass to the
inlet and outlet of the valve.
9. Turn on the water supply or put the bypass valve(s)
into the service position and purge the air out of the
system.
To check for proper meter operation, open a downstream
faucet and observe the water fl ow indication on the
control display.
