MAINTENANCE
Attention
Any valve maintenance and/or installation operation must be carried out in the
absence of hydraulic pressure. For this reason, disconnect the water delivery
line to the valve.

Cause Corrective action
Leak from pilot 1 - Turn off the water inlet.
2 - Turn off the water outlet.
3 - Disconnect the connection tube between the pilot and the drain connection.
4 - Remove the 3 screws securing the manifold. Remove both o-rings and replace
them with two soft rubber discs of the same outer diameter, each measuring
2mm in thickness.
5 - Refit manifold by tightening the three screws and taking care not to
force them.
6 - Reopen the water inlet and outlet. Once the procedure is complete, if the outlet
leak has disappeared, the fault was due to the pilot. Replace the pilot.
Leak at inside of pilot Replace pilot group reference 2250/05.

7 - If the water leaking from the outlet is hard, the assembled inlet piston needs
to be replaced, reference 1918/05.
8 - If the water leaking from the outlet is soft, the assembled outlet piston needs
to be replaced, reference 1918-C/05.

Problems in salt/brine 15 - Thoroughly check the connection assembly to the brine tank:
tank g) - Check that there are no obstructions in the connection system.
h) - Check that there is a flow when the float is in lower position.
i) - Check that there is no formation of a salt bridge in the brine tank.
j) - Check that all components of the brine valve operate efficiently without any
leaks from any fittings.
