10. Flush RO permeate or deionised water into
the “full flow cleaning” adapter (7) on the
feed side of the membrane. Flush out the
cleaning solution.
It is essential that the water used for the final
pre-flush is pre-filtered to a level described in
the datasheet.
11. When flushing is finalised – Close the high
pressure “full flow cleaning” valve (7) and
close valve (28).
12. Connect the high pressure pipe to joint (9)
again.
