SECTION 4: SERVICE INSTRUCTIONS & MAINTENANCE

VALVE SERVICE

COVER

The cover provides protection for the controller, wiring, and other components.  This cover will be removed for most service and maintenance.

When installed, the cover provides NEMA 3 water protection.  This protects from falling water up to 30 degrees from vertical.

To remove cover:

1) Grasp side edges toward rear of the valve.

2) Pull outwards until the slots in the cover clears the projections on the top plate.

3) Lift up on the rear and pull forward to clear the control module.

To install cover:

1) Position cover to be low in front and under the bottom edge of the control module.

2) The cover will hook on the bottom of the controller and drop down over the camshaft.

3) To fi nish, grasp the side edges and pull outward to clear the projections on the top plate.

4) Drop down until the cover snaps in place.

ELECTRONIC CONTROL MODULE

The purpose of the electronic control module is to control the regeneration cycle.  The control module has several variations.  When replacing the controller, use the 
same model or some functions may not work.  This is an electronic controller that is programmable and uses input/output signals.

To remove control module:

1) Disconnect power to the unit.

2) Remove valve cover.

3) Press trip lever to release module from top plate.

4) Pivot the top forward and up.

5) Remove any wire connections.  Wire connections have a locking tab that must be squeezed before removing.

NOTE: There is no need to label the wires.  The keyed connectors will only plug back into one site.

To install control module:

1) Be sure the power is disconnected.

2) Check model.

3) Check routing of wires and plug them into the controller.  Connectors will snap in place.  Be sure that wires are properly managed through the clips on top plate.  
This will prevent the wires from being caught in the camshaft.

4) Place bottom of module in position.  The bottom will fi t into a clip.

5) Pivot the top into position and snap in place.  The controller should be secure.

If you are ready to program the controller, then power can be applied by plugging in transformer.
