6. The top section of the valve should be blown out with a canister of compressed air. Air
should flow freely from the bottom through both sides at the top. A few short bursts of
canned air in both holes should displace any debris. Alcohol can also be used to remove
any build-up of sediment. (Do not use an air compressor to blow out the valve; water in
the airlines may be forced into the manifold.)
7. The bottom section contains a plunger and spring. Make sure the three grooves on the
sides of the plunger are clean. This part should be cleaned with a cotton swab and
alcohol to remove the debris.
IMPORTANT: If a valve is found to have only one groove, please contact KEGEL for an
immediate replacement. All machines should have the "high flow" valves which are
machined with three grooves. Please call (863) 734-0200 if a replacement is needed.
8. Replace the valve body on the head of the valve using the same shim washer(s). Do not
over tighten!
9. Replace the valve on the back plate.
10. Plug the line or elbow back into its proper fitting and clean around all the connections.
11. Return the oil assembly to the machine and plug in the connections.
12. Run the OIL VOLUME test once to clear the lines out. Then check the volume of
conditioner output for a typical program and adjust the pump if necessary.
