Replacement of turbine inserted
Dismount the flow sensor. The sensor housing is sealed and must not be opened.
Press the turbine insert out of the tube piece in flow direction using a flat tool.
The insert fits very tight in the tube piece. You should not use your fingers and never
use a pointed tool to press it out of the tube.
The turbine insert consists of two cylinders of different diameters which must never be
dismounted.
Push the new insert with the small diameter to the front into the pipe section against
the flow direction. Turn the insert in such a way that the webs are not directly beneath
the Hall sensor or the proximity switch. Press the insert into the pipe section up to the
stop. The position will be correct, if the face of the inserts is flush with the pipe section
(applies only to metallic version). Plastic version: push the insert up to the stop, now
do the same with the spacer. The spacer must be flush with the tube piece.
Reinstall the DR08-25 in the piping. Make sure that the provided seals fit properly.
