Remove the sight-glass windows (9) and the respective flat seals
(8).
Use cleaning spirit to clean the film off the sight-glass windows. If
the instrument has been used to measure hard water for a longer
period of time, a hard-to-remove film may have formed on the
sight-glass windows. In this case, clean the sight-glass windows
and the measuring chamber as described below.
Clean the measuring chamber with a cleaning agent suitable for
decalcification and rust removal (max. 5 – 10% solution). Flush the
measuring chamber thoroughly after cleaning.
Once the measuring chamber has been fully cleaned, it can be
reinstalled. Reassemble in reverse order to disassembly.
Once all assembly work has been completed, bleed the lines be-
fore restarting the instrument (see the section entitled “Inserting
the indicator bottle” on page 26).
