Notices
•
It is imperative to implement the interfaces of
the flexible tube “cleanly” so that the sealing
ring does not become damaged in the quick-
release coupling.
•
When clicking in the flexible tube, make sure
that the tube and quick-release coupling are
pressed well against each other to prevent
wrong air from being sucked in.
•
The maximum length of the flexible tube must
not exceed
1.5 m
.
