1. Compressing the corrugated pipe
The PE-corrugated pipe is compressable and can be adjusted with the red resp. blue end sleeve. It is not necessary to cut the corrugated pipe before connecting it.
2. Put the sliding sleeve onto the pipe
Before expanding the connection pipe, the aquatherm grey pipe-sleeve has to be slided onto the pipe. This sleeve is identical on both sides - inside and outside. It does not make any difference which side is pushed onto the pipe resp. onto the fitting.
3. Expanding of the connection pipe
For expanding of the pipe end, the tool must be opened totally for inserting it into the pipe end. Then the expanding tool is compressed - the aquatherm grey pipe-connection pipe is bulge formed. For an easy pipe assembly with the fitting, the tool must be opened again, turned slightly and compressed for the even expansion of the pipe end.
The expanded pipe end is pushed on the corrugated part of the pipe supporting body at the manifold branch resp. the fitting up to the stop.
Now the assembly tool is put on. By compressing the tool the sleeve presses the plastic pipe onto the supporting body. That quick and safe a permanent connection is installed. Then the compressed corrugated pipe is pushed with the end sleeve up to the fitting.
