6.6 Periodic maintenance
6.6.1 Membrane replacement
The reverse osmosis membranes last for an average period of time of 6-7 years. When the membranes are
old, the quality of water usually decreases whereas the working pressure increases. If chemical washings do
not produce significant improvements, it is recommended to replace the membranes.
6.7 Adjustments
Accumulator
It is a polypropylene 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 6 bar. The charge level must be
periodically checked in order to guarantee a correct
functioning to the watermaker.
