9.12.1 Installing plastic push-fit connectors (heating side and
heat source side)
Note
The plastic push-fit connectors are not suitable for instal-
lation in the DHW line.
f
Only install the push-fit connectors in the heating or
brine circuits.

Material losses
f
Tighten the screw cap of the push-fit connector by
hand. Never use a tool.
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: 17±0.5 mm
- Pipe diameter 28 mm: 21±0.5 mm

Material losses
Support sleeves are required when using plastic pipes.
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. In addition, the
push-fit connectors are equipped with the "twist and lock" func-
tion. Simply turning the screw cap by hand will secure the pipe
in the connector and push the O-ring against the pipe to seal it.
Making the push-fit connection
The connector must be in its relaxed position before the pipe is
inserted. In this position, there is a small gap between the screw
cap and main body.

Material losses
Pipe ends must be deburred.
f
Always use a pipe cutter to trim pipes.
f
Push the pipe past the O-ring into the push-fit connector
until it reaches the prescribed insertion depth.
f
Finger-tighten the screw cap as far as it will go against main
body. This secures the push-fit connection.
