" 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.
2 Sensor Cap 1 The Sensor Cap should be snapped in place.

4 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.
5 Turbine Assembly 1 The Turbine must have a 1 ⁄
8
" 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.
