Pre-filtration unit
The pre-filtration unit is positioned between the pre pump (pump 1) and the watermaker, and it is composed
by one big blue 20 microns and one big blue 5 microns, a low pressure switch, a 0-6 bar manometer and a
plastic non return valve. A white push-button, positioned on the top of the filter housings, allows to purge out
the air during the start-up operations.
The
Low pressure switch
stops the watermaker if the water flow rate is too low avoiding cavitation of the
main pump. The pressure switch calibration is approximately 0,6 bar
