8.3.2 Replacing the compression ring
In order to guarantee proper functioning of the "anti-retraction valve in
the spray water duct", we recommend replacing the compression ring
(C) every six months.
1. Purge the spray water duct at the maximum water flow.
2.
Slide the tool, with the new compression ring attached, to just in
front of the corresponding groove (C).
3. Insert the compression ring. Do not use any sharp objects.
4. Check that the ring fits snugly all the way around and is not
twisted.
