Pump high pressure switch
The main pump is equipped with a high pressure switch set
at around 15 Bar.
The pressure switch can be calibrated with a screwdriver. To
calibrate the pressure switch pull out the plug, remove the
security nut, and engage the small internal screw with a small
screw driver.
Turning clockwise the calibration of the pressure switch
increases, while turning anticlockwise the calibration
decreases.

pressure oscillations during the commutations of the
watermaker. The accumulator is factory loaded at a pressure
of about 9 bar. The charge level must be periodically checked
in order to guarantee a correct functioning to the watermaker.
