NOTICE
Overheating of the measuring turbine!
The bearing of the measuring turbine is cooled by
the water fl ow during operation. The use of
compressed air for cleaning can lead to irreparable
damage due to overheating.
!
Clean the measuring turbine with running water
only.

appropriate spray nozzle is particularly suitable for this
purpose.
15
Check that the measuring turbine has been cleared of
foreign substances and is running smoothly again.
16
If the cleaning was successful, install the fi tting in the
reverse order of removal.
If the measuring turbine is still blocked, you
must remove the sleeve with measuring
turbine as described in par. 9.4.2.1.
The removed fl at seals are not reusable. Use new
seals for reassembly.
