5.1 Reset procedure
If the watermaker has sucked in air (or if other problems occur), the automatic hydraulic valve may stop in a
central position.
In this case, when the unit has been started, it gets suddenly high pressure (close to 10 bar) without cycling.
In this case the system has to be manually resetted.
Although this circumstance might be very unusual, it does not damage the system, but it is necessary to reset
the valve with the following simple procedure:
1. Open the reset valve (lever in horizontal
position).
2. Open slightly the depressurization valve.
3. Screw the positioner knob until it can be
moved no further. Normally 18 complete
turns at least are needed.
