6.7 Periodic maintenance
6.7.1 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 13 Bar.
The pressure switch can be calibrated with a 2 mm
hexagonal key. To have access to the calibration screw it is
necessary to operate on the screw that blocks the electrical
connector of the pressure switch, and then introduce the
hexagonal key (even without removing the electrical
connector itself). Turning the key clockwise increases the
calibration of the pressure switch, while turning the key
anticlockwise decreases the calibration.
Pulsation dampener
It is a cylindrical PVC receptacle of air that has the function
of damping the pressure oscillations during the
commutations of the watermaker. The dampener is factory
loaded at a pressure of about 6 bar. The charge level of the
dampener must be periodically checked in order to
guarantee a correct functioning to the watermaker.
