4.)
Now the cleaning solution (see. chapter 10.2.) can be added using
the clear water hose (Respect decline from clear water tank down
to the tank with the membrane station). At small tank systems
with good accessibility (for instance, AL-System 6) the cleaning
liquid can be filled directly into the back flushing tank.
Note:
The cleaning solution must be refilled during the cleaning process
in case of more than three membranes installed as the back
flushing tank has only approx. 6 l holding capacity.
5.)
If the cleaning solution is filled, then the cleaning cycle starts with
ENTER. An internal routine now runs. The routine takes about one
hour.
6.)
After the completion of the cleaning routine a clear water
flushing must be started. At least two litres of clear water are filled
into the back flushing tank for each membrane.
7.)
With ENTER the clear water flushing is confirmed. The routine
takes about max. 4 minutes.
After the completion of the clear water flushing, the operation
mode appears in the display and the normal program continues
to operate further, corresponding to the set parameters.
For a further cleaning step the cleaning menu must be started again.
ATTENTION!
If chlorine cleaning is performed after acid cleaning, then the pipes must be
sufficiently rinsed (see description Step 6.)
