Cut the corrugated pipe to the desired length cleanly and burr-free with a pipe cutter (do not rework with a file, make a further cut if necessary).
- You will find a suitable pipe cutter here.

Rohr abschneiden

Never unscrew the fitting! If this should happen by mistake, make sure that the wider side of the inner ring (foot) rests on the fitting.

Rohr einsetzen

After the corrugated pipe has been cut as shown in Fig. 3, the corrugated pipe should be inserted into the screw connection. To do this, you must first open the screw connection by half a turn (see Fig. 5) (unless the screw connection is already sufficiently loosened). Now the corrugated tube has to be inserted into the screw connection until you hear a "clack" noise.

Rohr verschrauben

Now tighten the screws as shown in picture 8. Finished
