8. Turn of the pump and allow the elements to
soak.
9. Feed the cleaning solution at high flow into
the “full flow cleaning” adapter (7) on the
feed side of the membrane. The high flow
rate flushes out the foulants removed from
the membrane surface by the cleaning.
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-fil-
tered to a level described in the Data sheet.
11. Remove plug (9). Water will flow out of the
iSave and the iSave may start to rotate
backward – this is OK.
12. Continue to flush the iSave until no chemi-
cals are coming out of the iSave.
13. When flushing is finalised – Close the
high- pressure “full flow cleaning” valve (7)
and close valve (16).
14. Connect the high pressure pipe to joint (9)
again.
