Pipe ends must be deburred.
Always use a pipe cutter to trim pipes.
Push the pipe through the O-ring into the push-fit connector
until it reaches the prescribed insertion depth.
Tighten the screw cap by hand against main body as far as it
will go. This locks the push-fit connection.
Undoing the push-fit connection
If the push-fit connectors later need to be undone, proceed as
follows:
Turn the screw cap anti-clockwise until there is a narrow gap
of approx. 2mm. Press the retainer back with your fingers
and hold on to it.
Pull out the inserted pipe.
