Membrane replacement
Reverse osmosis membranes have an average lifetime of about 7 years If correctly maintained. It is anyway
recommended to check the efficiency of the membranes after 5 years of functioning and verify the needed of
a replacement. Please, refer to a certified Schenker service center for this operation.
6.8 Adjustments
Pump high pressure switch
The main pump is equipped with a high pressure switch set
at around 9,5 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.
Accumulator
It is a cylindrical reservoir of air that has the function of
damping the pressure oscillations during the commutations
of the watermaker. The accumulator is factory loaded at a
pressure of about 4 bar. The charge level must be
periodically checked in order to guarantee a correct
functioning to the watermaker.
