Cleaning the system tank
Drain the system tank (chamber). This can be done using
a wet vacuum cleaner.
Make sure that the system tank (chamber) is free of sus-
pended matter and solids, clean if necessary.
Make sure that the protective tube for level measure-
ment (1) is free of suspended matter and solids, clean if
necessary.
In the case of stubborn soiling, remove for cleaning.
Make sure that the dimension (L) (switching point for
the level sensor, see "Level sensor", page 36) remains
unchanged.
Flushing the pressure pipe
Where pressure pipes are especially long, the pressure pipe
should be flushed separately after the system has been
cleaned in order to prevent deposits lodging in the pressure
pipe.
Flush the pressure pipe via the flushing connection (14).
