When replacing the coil, ensure that when removing the coil wire cover that care is taken not to damage the wires inside. Using the medium flathead screwdriver, gently use it to open the cover enough to where it could be pulled off. Loosening the conduit nut 7. Using a pair of channel locks, gently loosen the conduit retaining ring for the conduit nut. Once it is loosened, use your fingers to unscrew and remove it. 8. Pull the conduit away and discard the bad coil. Take the new coil and attach the conduit, reinstall & tighten the conduit Straightening the wires 5. Once the coil wire cover has been removed and set to the side, take the internal wires and pull them out straight. Removing the wire nuts 6. Remove the wire nuts from the wires and separate them. nut, and pull the wires through so that you will be able to wire the valve back up. 9. Reconnect the wires from the conduit to the wires from the solenoid as they had been connected previously. Ensure that the wire nuts are on tight. 10. Slide the coil wire cover back on, taking care not to damage the wires. 11. If you are done performing maintenance on the valve, continue on to step 23. Otherwise, please go on to step 12.L Loosening the valve bonnet 12. To remove the valve bonnet, grasp it with the jaws of the pipe wrench and turn to the left. Note: on some models you may have to remove the valve in order to perform this and any further steps. Be careful not to damage the plumbing assembly. Only use the pipe wrench enough to where you can spin the valve bonnet off with your hand. 200 Series Technical Manual 7610-100-45-00 Rev.

Note: The spring for the plunger is located directly under the bonnet and may come free if you are not careful. Remove the plunger, spring and valve bonnet and place to the side. Removing the O-ring 14. Remove the O-ring and inspect it. If it has any tears or cuts or excessive flat spaces, it should be replaced. 15. Examine the threads for the valve bonnet. Check them for scoring or signs of damage. Take a cloth and clean them out to remove any foreign particles that might get lodged in the threads and cause a leak. Severely damage threads should not be repaired; instead it is recommended that the entire valve should be replaced. These instructions do not provide information on replacing the solenoid valve. 16. Note: Even though an O-ring may not appear damaged, it is a good idea to go ahead and replace it if you have a new one. This will help ensure that your valve remains leak-free in the future! 17. Remove the diaphragm retainer and then the diaphragm itself. Many problems associated with a solenoid valve can be traced to a clogged pilot port in the diaphragm. Pointing out the extension hole 18. As indicated in the photo above, the extension hole can become clogged. If it is difficult to clean out, you can use a heated straight pin to push through the hole. The center hole, the pilot port, must also be clear. If the diaphragm is torn or bent in any way, it must be replaced. 1 2 Diaphragm showing (1) pilot port and (2) extension hole 200 Series Technical Manual 7610-100-45-00 Rev.

Verify that the holes in it are free of clogs and debris. 21. With the mesh screen removed, look down into the valve and verify it is not clogged. Remove any foreign objects from the valve body that would obstruct flow. 22. Reassemble the valve, reversing the steps needed to take it apart. Replace defective replacement parts with new parts from ordered kits. Ensure that components are sufficiently tightened to prevent leakage. AFTER MAINTENANCE ACTIONS Reconnect the incoming water (if disconnected) and turn on. Then restore power to the unit. Run the unit for at least 10 minutes to ensure there are no leaks. If any problems arise please contact your Jackson representative. Removing the mesh strainer screen 20. Again using the small flathead screwdriver, carefully remove the mesh screen from inside the valve body. The screen should be taken and rinsed out to remove any debris fouling it.
