4) Remove connections by squeezing the latch on the connector and pulling out.

5) Pull the harness out of the clips on the top plate.

To install a wiring harness:

NOTE: Start at the back of the valve and work toward the controller. This will place any slack behind the

controller. Slack or loose wires can become tangled in the camshaft.

1) Depending on which harness is being installed, plug the connector into the motor or turbine.

2) Route the harness through the opeing at the back of the top plate.

3) Place the harness into the clips on the top plate. Do not leave any slack. Put the motor wire in ﬁ rst, then the

turbine sensor cable second.

4) Feed the wire through the opeing on the front of the top plate.

5) If installing the motor harness the connector to the optical sensor can be clipped in place.

6) Connect the harness to the back of the controller.

NOTE: If using both a motor and turbine cable harness, install the smaller motor cable ﬁ rst. Install the

larger turbine cable second. This will lock the motor cable beneath in the wire management clips.

SPRING (VALVE DISCS)

This spring is a one-piece metal spring that applies pressure to the valve discs holding them closed. The rotat-

ing camshaft overcomes this pressure to open the valve discs as needed. The shape of the spring is critical for

proper operation.

CAUTION: Do not attempt to straighten or repair this spring. If this spring is damaged, valve discs may

not operate correctly.

To remove spring:

1) Disconnect power to the unit.

2) Remove cover.

3) Remove motor.

4) Remove camshaft.

5) Place unit in bypass.

6) Release water pressure by pushing the last valve discs open with a screwdriver.

7) Locate valve discs 3, 4 and 5.
