Fresh water production cycle with automatic washing.
(
For use when the watermaker is not used on a daily basis or when automatic washing is
required after every water making session.)
1.
Preset the pumps by turning the PUMP1 switch clockwise.
2.
Preset the automatic washing by turning the AUT. WASHING switch clockwise.
3.
Push the START button to start the plant (the START push-button pilot light come on and
the production will begin).
4.
Push the STOP button at the end of the production cycle. The plant will not turn off
immediately, but a washing cycle will be automatically activated lasting approx 50sec.
During the cycle the MAN WASHING push-button pilot yellow light will also light up. The
watermaker will automatically shutdown after the washing cycle has finished.
The fresh water consumption during an automatic washing operation is approx. 5 litres
Manual washing cycle.
(suggested if it is intended to reactivate the plant not before 2-3 months)
This operation is not intended for fresh water production, but serves to perform a deeper rinsing
of the watermaker, prior to long periods of inactivity.
Before starting the manual washing, ensure that there is a sufficient quantity of fresh water inside
the vessel's water tank. Fresh water consumption during this washing cycle is approx. 5
litre/min
1.
Turn on the pressure water system.
2.
Prearrange the pump turning the PUMP1 selector clockwise.
3.
Do not prearrange the automatic washing, assuring that the AUT. WASHING selector is in
vertical position.
4.
Push the MAN WASHING button to start the washing cycle (the START and MAN
WASHING push-buttons pilot lights will turn on).
5.
Push the STOP button whenever it is desired to stop the washing cycle.
It is suggested to not performing washing operations longer than 10 min. as far as this time range
is sufficient to guarantee a total elimination of the salt contained in the plant.
ATTENTION
If the watermaker has been stopped by using the pump switches and not the Stop button, or if
some air is in the system, 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.
The symptoms of this are when the pumps are turned on, the manometer reaches an elevated
pressure (approx. 8-9 Bar) and the pumps shutdown automatically by the pressure switches
intervention. 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 computer
senses the anomaly, and turns the pumps off by activating STOP push-button. (The light flashes).
