· PEX: support insert has to be used

Support insert shall be used on thin-walled PE pipes (for example SDR 17,6, on geothermal heat pumps etc.)

Assembly instruction:
· Cut the pipe, deburr.
· Loosen the nut, do not dismantle
· Mark insert distance (P) and push the pipe to the stop
· Tighten the nut against the body.

A good seal is only obtained when the pipe is pushed past the O-ring, up to the pipe stop and the nut is tightend against the body.
When using Isiflo coupling on cupper or steel pipes, shall the pipe always be installed with a clearance of approx. 3 mm from the internal stop.
