WATER METER MAINTENANCE

Demand Systems

The valve metering devices are used with the demand controls, and 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 controller) with a screw-

driver.

3) Loosen and remove the pipe/tube adapters or 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.

5) Carefully remove the turbine wheel from the housing. Use a toothbrush to lightly scrub debris or iron off the

magnet. Iron build-up on the surfaces can be reduced by soaking the wheel in mild sodium hydrosulﬁ te (such

as Iron-X) solution for a few minutes. Flush thoroughly with water.

6) Carefully reinstall the turbine wheel into the turbine cage housing. Make sure that the shaft 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 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.

10) The system will require the statup procedure to be performed in order to operate appropriately.

CHECK TURBINE OPERATION

After the turbine has been cleaned, verify that the turbine is accurately working. Repressurize the conditioner

system, and verify that the controller is plugged in. Completely turn on a faucet that is plumbed after the condi-

tioning system. After a few seconds, the display should be ﬂ ashing a small faucet icon with water drops. If this

is ﬂ ashing, the turbine is operating properly.

If the faucet icon does not ﬂ ash, then the system may have a faulty turbine probe cable wire harness. Replace

that harnesss and repeat the steps above for checking for turbine operation.

REFILL FLOW CONTROL

If the brine tank is not reﬁ lling correctly (too much or too little water) the reﬁ ll ﬂ ow control should be cleaned and

inspected.
