10. Replacing the Non-Retraction Valve
A water Non-Retraction Valve is integrated in the Coupling Joint, which
shuts off the water retraction directly at the handpiece head to prevent
fluids infiltrating the water line. If water is beginning to leak from the
handpiece, replace the non-retraction valve.
1) Remove the Coupling Joint from the hose.
2) Remove the back-end Gasket.
3) Pull and remove the water tube, and replace the Non-Retraction
Valve. (Fig.18)
4) Insert the new Non-Retraction Valve securely and remount the
back-end Gasket.
