aquatherm® SHT uses an interlocking connection giving it a durable, tight result.
The connection technique involves pressing the aquatherm® SHT sliding sleeve onto the aquatherm® SHT pipe using the fitting. It is important to use only the aquatherm® SHT system pipes, tool, fittings and connection pieces made by aquatherm when connecting with sliding sleeve.
If using corrugated pipe the PE- corrugated pipe is compressed and can be adjusted with the red or blue end sleeve. It is not necessary to cut the corrugated pipe before connecting it.
Before expanding the connection pipe, the SHT- Sleeve has to be slid onto the pipe. This sleeve is identical on both slides - inside and outside. It does not make any difference which side is pushed onto the pipe, onto the fitting.
To expand the pipe, the tool has to be opened completely, so that you can insert it into the pipe end; the expanding tool is pressed together; the aquatherm® SHT connection pipe is bulge formed, the tool should be opened again, turned slightly and closed again that the pipe is expanded steadily.
If the temperatures are below 0°C, the pipe must be warmed up by hand before expanding it. White discolourations are unproblematic. With EVOH-oxygen tight pipes the coating is only expanded lightly neither without influencing the tightness of the pipe connection nor the oxygen barrier.
NOTE: The sliding sleeve must be kept away from the expanding area as otherwise the tool and pipe might be damaged.
The expanded pipe end is pushed on the corrugated part of the pipe supporting body up to the stop.
Now the assembly tool is put on.
On compressing the tool the sleeve presses the plastic pipe onto the supporting body. That quick and safe unsolvable connection is installed.
