WARNING
Dangerous chemicals.
Improper use of chemicals can cause damage to your
health.
Heed the following rules:
 Read the labels of the ChemBags and follow the safety
instructions
 Wear protective equipment (lab coat, protective gog-
gles, chemical resistant protective gloves)
1 Prior to each chemical cleaning, pre-clean the membrane with the spe-
cial brush and rinse it with water (see section 5.7.1 Mechanical cleaning
of the filter plate,
 117).
2 Dismount the filter unit from the slide.
3 Dismount the intake line from the filter unit.
4 Protect the filter plate against any contamination coming in (e.g. by clos-
ing the connection adapter for the intake line).
5 Dismount the filter plate (see section 5.7.4 Replacing the filter plate of
the sample filtration,
 121).
6 Close the connector of the filter unit and the open intake line with blind
plugs to that no contamination can get into the filter.
The chemical cleaning of the filter plate may take some time.
Use a replacement filter module (FM/PC) during the cleaning pro-
cess to keep the downtime of the Alyza IQ as short as possible.
7 Completely submerse the filter module with the installed filter plate in
the cleaning container filled with the cleaning solution.
 Start with a reaction time of 30 minutes.
 Watch the cleaning success and extend the reaction time as neces-
sary.
