" I/O Assembly

1

Makes the connection between the plumbing and Main Valve Body. Also, contains the “Hard Water” Blending Valve. The

seal areas of the O-rings at the Main Valve Body inlet and outlet must be smooth and free of defects and debris, and

be lubricated with silicon grease before assembly. When attaching to the Main Valve Body, put the O-rings on the male

bosses on the Main Valve Body and push the Adapter into place. A “snap” can be heard when the ADAPTER slides into

place; if not, the O-rings may be “pinched.” If O-rings are pinched, replace with new ones. The I/O Adapter comes pre-

assembled with the sensor housing and turbine axle.

These are not field serviceable and if damaged, must be replaced with a new assembly.

Turbine Sensor

Assembly

1

Picks up the magnetic field from the Turbine and relays it to the Controller. The three wire assembly connecting the

“black-wafer” Hall-Effect Sensor or the Controller board must not be severely bent (folded over), cut, or broken. Care

should be taken when putting the Sensor into the Sensor Housing. The “spring” flap below the Sensor must be gently

bent over (on top of) the Sensor, and then the Sensor slide all the way into the Sensor Housing. The round hole of the

Sensor mounting tab is then placed down over the mounting screw boss. The cap is then put in place and the mount-

ing screw is installed. A slot is provided in the cap for the wire way to exit. The three-wire socket connector must be

properly installed in the controller. Stops on the connector prevent improper (upside down) assembly. Do not force the

connector past the stops.

Turbine Assembly

1

The Turbine must have a

" diameter Rare Earth magnet pressed into place adjacent to the axle opening. When

assembled to the axle, the Turbine should spin freely. Do not use any lubricants. If the Turbine should become

“jammed,” clean and flush the Turbine and I/O assembly.
