5 – FUNCTIONING AND USE
Note: in order to avoide false and continuos starts/stops, as conseguence of the pitching of the boat, the
computer recognizes the command of of the level switch only after 60 seconds of stable state.
5.5 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:
1. Turn off the system
2. Open the reset valve (lever in horizontal
position).
3. Open the depressurization valve at 45°.
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 counterclockwise up
to the original position, until when it is blocked
back.
6. Close the reset valve (lever in vertical position).
