ter. Then the pump(S) will start after 5 seconds.
The display will show the increasing production time.
-Push STOP to stop the unit.
If the washing has been selected, the system will start the washing procedure, and then will stop
automatically after 1 minute.

The system will stop after the selected hours, performing before, if selected, the automatic washing.
Anyway the system can be stopped at any time pushing STOP.

-Push washing for more than 3 seconds.
The display will indicate the remaining time. It is possible anyway to stop the operation at anytime
pushing STOP.
Periodic washing
-Select the days (6-10) in the washing menu
- Exit from the menu pushing STOP
- Push WASHING for 3 seconds.
The display will indicate the remaining day before the first rinsing.
The function is anyway disabled pushing STOP, or after a normal production cycle
.
ATTENTION
If the watermaker get air, (or if some other problem occurs) the automatic hydraulic valve may stop
in a central position. This means that pressure on both sides of the valve are the same and the unit is
effectively stalled and has to be manually restarted.
In this case the working pressure goes up suddenly (up to 8-9 Bar) and the pumps are switched off
from the pumps pressure switch. The pumps then have the tendency to try to restart when the pressure
decreases, and then to jam again, resulting in a typical start-stop noise. After approx. 20 sec. the com-
puter recognize the problem , and turn off the pumps, and the message “WARNING SYSTEM
BLOCKED” is displayed.
This event, besides being very unusual, does not damage the system, but it is necessary to reset the
valve with the following simple procedure:
RESET PROCEDURE
1.
Turn the system off.
2.
Open the reset valve (lever in horizontal position).
3.
Screw the positioner knob clockwise until it can be moved no further.
10 turns at least are necessary.
4.
Unscrew the positioner knob up to the original position, until when it is blocked
back.
5.
Close the reset valve (lever in vertical position).
6.
Restart the system
