9.12.2 Installing copper push-fit connectors (DHW side)
Note
The copper push-fit connectors are only designed for use
in the DHW line.
!
Material losses
To ensure the push-fit connector is held securely, pipes
with a surface hardness > 225 HV (e.g. stainless steel)
must have a groove.
f
Using a pipe cutter, cut a groove (depth ap-
prox. 0.1 mm) at a defined distance from the end of
the pipe.
- Pipe diameter 22 mm: 12±0.5 mm

f
Push the pipe into the push-fit connector by hand.
Never use a tool.
How the push-fit connectors work
The push-fit connectors are equipped with a retainer with stain-
less steel serrations and an O-ring for sealing. Simply pushing it in
by hand secures the pipe in the connector and presses the O-ring
against the pipe to seal it.
An extraction tool is necessary to release the connection.
