tube is parallel to the support rod (7).
From the bath side, slide the silicon ring (12) - curved
face first - on the vapor tube (A). Then slide the
PTFE seal (11) - sealing lip first - on the vapor
support tube as far as it will go.

position. Re-tighten the red locking knob (14).
Screw the butt flange (G) to the threaded socket on the side of
the vapor support tube (A) and insert the sealing ring (G1).
Place the clamp (15) on the support rod (7) and fasten the
