5.4 Reset procedure
If the watermaker sucks air (or if other problems occur), the automatic hydraulic valve may stop in a central
position.
In this case, when the unit is started, it gets suddenly high pressure without cycling. After few seconds the
computer recognizes the problem and turns off the pump.
In this case the system has to be manually reset.
This event, besides being very unusual, 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 know clockwise until it
can be moved no further. Normally 18
complete turns at least are needed.
