Cleaning and Maintenance
Attention:
The upper union nut (red) is sealed!
It must not be opened.
If this component is opened, the fixation of the turbine
system loosens and it is damaged.
A factory repair will be necessary!
To remove dirt from the flow sensor, you should flush it
with water always in opposite direction to the flow.
Warning:
A possible blowing out of the device with compressed air must only be carried out in
opposite direction to the flow.
