Removing:

Push quick-release coupling (1) against pipe (4) (thereby relieving strain on spring (2).

Press plastic ring (3) into quick-release coupling (1) and remove coupling (1).

Installing:

Markings (K) on coupling (1) and pipe (4) must be flush.

Push quick-release coupling (1) onto pipe (4) until a "click" can clearly be heard.

To check that quick-release coupling (1) has been installed correctly, pull it back forcefully.
Quick-release coupling with indication pins

Removing:

Press plastic ring (2) into quick-release coupling (1) and remove coupling (1).

Installing:

Push quick-release coupling (1) onto connector (3) until both indication pins (4) can be seen and felt to point outwards at outside diameter of housing.

To check that quick-release coupling (1) has been correctly fitted, feel indication pins (4) at outside diameter of housing. When correctly seated, indication pins (4) cannot be pressed into housing.

CAUTION: Coupling is not correctly engaged if both indication pins (4) fail to protrude from housing. Leakage is thus unavoidable.
