6.7 Periodic maintenance
6.7.1
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.
6.8 Adjustments
Accumulator
This is a cylindrical plastic receptacle 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 charging pressure
of the dampener must be periodically checked.
