PROCEDURE FOR CLEANING/REPLACING THE FLOW SWITCH

A) Remove the external protections and the electronic boards. Unscrew the 8 screws securing the dissipation plate. Remove the
dissipation plate and put it aside so that it is not scratched. If the dissipation plate is oxidized, restore it using 1000 grit grade sandpaper.
B) Remove the sliding support of the valve by pulling it upwards. Let the valve and the spring rotate along the longitudinal axis to
enable removal.
C) Clean the valve with compressed air. If the seal shows any sign of cuts, replace the whole valve. Refit the valve and the spring with
the guide support. Make sure that each part is positioned correctly, as the support only has a centring ring for the spring on one side and
the valve has a reference for correct positioning.
