13.4 Reset procedure
If the watermaker get air (or if some other problem occurs), the automatic hydraulic valve may stop in a central
position. This means that pressures on both sides of the valve are the same and the unit is effectively stalled.
In this case the system has to be manually restarted.
An evidence of this effect is confirmed by a working pressure going up suddenly. After approx. 20 sec. the
computer recognizes the problem, turn off the pumps, and the red led start flashing.
This event, besides being very unusual, does not damage the system, but it is necessary to reset the valve
with the following simple procedure:
5. Unscrew the positioner knob up to the original
position, until when it is blocked back.
