damage the valve.

After demounting the nozzle unit it has to be tested for pollution and cleaned if necessary, before a
remounting is carried out. Before mounting the nozzle unit make sure that the valve seat and the tappet
top are free from any contamination that may cause damages to the sealing of the valve seat.
After cleaning, you have to inspect O-ring sealings and exchange them if necessary.
