5.5 Reset procedure
If the watermaker gets air (or if some other problems occur), the automatic hydraulic valve may stop in a central
position. This means that the working pressure goes up suddenly. After approx. 20 sec. the computer
recognizes the problem, turn off the pumps, and the “SYSTEM BLOCKED” message starts flashing.
In this case is necessary to reset the valve with the following simple procedure:
1. Turn off the system
2. Open the reset valve (lever in horizontal
position).
3. Open the depressurization valve.
4. Screw the positioner know clockwise until it can
be moved no further. Normally 10 turns at least
are needed.
5.
Unscrew the positioner knob up to the original
position, until when it is blocked back.
