1. Disconnect power to the control by unplugging the walltransformer or unplugging the power cord from the bottomof the control.2. Press down on the top of the drive gear to disengage thecam gear.3. With the cam gear disengaged, rotate the cam gearcounterclockwise to the REFILL position until the air checkfills with water, and water flows through the brine line intothe brine tank. Do not run for more than three minutes.4. Press down on the drive gear, and rotate the cam gearcounterclockwise to the DRAW/RINSE position. Check thatwater is being drawn from the brine tank. The water levelin the brine tank will recede very slowly. Observe the waterlevel for at least one minute. If the water level does notrecede, if it goes up or if air enters the transparent aircheck chamber and the ball falls and seats, refer tothe Troubleshooting section in this manual.5. When water is being drawn from the brine tank,press down on the drive gear and rotate the cam gearcounterclockwise to just before the SERVICE position.Connect power to the control and allow the motor to drivethe cam gear to the SERVICE position. The motor will stop.Run cold water from a nearby faucet until the water isclear and soft.Checking the brine draw and refill function.In rare instances, the turbine wheel of the water meter cancollect small particles of oxidized iron, eventually preventingthe wheel from turning.If the flow indicator light does not blink when conditionedwater is flowing from the unit, it is an indication that theturbine wheel is not turning.1. Disconnect electrical power to the unit.2. Shut off the water supply or put the bypass valve(s) into theBYPASS position.3. Relieve resin tank pressure:A. Remove control valve cover.B.

Generally,it will not be necessary to remove the inner gland.6. Clean all iron deposits and/or debris off the turbine wheel.Excessive accumulation of iron may be removed from thecomponents with a solution of sodium hydrosulfite (orsodium disulfite). Rinse the components thoroughly inclean water after using the iron removal solution.7. Flush accumulated iron deposits and/or debris from theinside of the valve outlet.8. Reinstall the turbine wheel into the outlet side of the valve,being certain that the turbine wheel shaft is carefullyseated into the bearing of the inner gland.9. Carefully reinstall the outer gland into the outlet side ofthe valve. Check turbine rotation.10. Reconnect the water conditioner to the plumbing andfollow Initial Start-Up section.11.
