Warning: the electronic computer is equipped with a minimum voltage block calibrated at about
10,8 volt (12 VDC systems) and at 21,8 volt (24 VDC systems).
This protection is necessary to avoid potential batteries damage (that could prejudice the
functioning of others accessories) if the system works for a long with low charged batteries.
At start (when you push the START button) the watermaker electric absorption has a little peak.
Therefore, if the batteries are low charged, it could happen that the system switches into the
protection position, thus not enabling to start up the unit under electronic control.
This event can be noticed looking at led on computer, inside the electric box. In normal
conditions this led is green. If the block due to the minimum voltage is activated, the led
becomes red for a few seconds. In this case check the batteries state, eventually performing a
recharge cycle.
Otherwise the watermaker could be switched on, in manual mode, inserting the by-pass.
3. Operation
3.3. Normal operation procedure
1.
Check that the seacock and waste water drain valve are opened.
2.
Check that the depressurization and reset valves are closed and that the by-pass is not
connected.
3.
Check that the Pressure Water system is turned on.
Fresh water production cycle without automatic washing.
The automatic washing procedure uses about 5 litres of water. If the unit is in use daily it is not
necessary to carry out this procedure every time water is produced. As long as the watermaker
membrane is cleaned once a week whilst in daily use, no long term damage will be done to the
watermaker.
1.Preset the pumps by turning the PUMP1switch clockwise.
2.Do not turn on the automatic washing switch. Check that the AUT WASHING switch is in
vertical position.
3.Push the START button (the START push-button pilot light come on and water production
will begin).
1.
Push the STOP button at the end of the production cycle. Do not turn the pumps off with the
pump switches as the shutdown operation will not be done electronically. There is a chance
that if turned off with the mechanism in a central position, the machine will become blocked
and need resetting manually. After pressing the Stop button the unit will not turn off
immediately, but after few seconds. This is quite normal as the computer repositions the
mechanism in the correct position before deactivating the pumps).
If during production the computer detects an anomaly (cycling missing, low
pressure, etc.) the watermaker will automatically shutdown 20 sec. after having
noted the anomaly and the STOP push-button pilot light will blink. It is
necessary to push the STOP button to restart the unit to confirm to the computer
that the failure has been recognized). Before restarting the watermaker, it is
necessary to check the reason for the failure and remove its causes.
