Figure# Part# Item Qty. Description
1 54510 3/4”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-assem-
bled with the sensor housing and turbine axle.
These are not fi eld serviceable and if damaged, must be replaced
with a new assembly.

4 93858 Turbine Sensor
Assembly
1 Picks up the magnetic fi eld 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” fl ap 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 Sen-
sor mounting tab is then placed down over the mounting screw boss.
The cap is then put in place and the mounting 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 90522 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 fl ush
the Turbine and I/O assembly.
