Page 7 The print lines on EDGE pipes are black, whereas RAUTITAN pipes print lines are white. In addition, compared to the REHAU RAUTITAN Pipes, the standard EDGE hot and cold water pipe is silver as opposed to platinum.
Page 8: Pipes And Fittings
Corrosion resistance of the pipes: No pitting No tendency for deposits Polymer pipe material reduces sound transmission along the pipe Good resistance to abrasion All EDGE pipes with WaterMark registration comply with AS/NZS 4020 (Components in contact with potable water) Peroxide-crosslinked polyethylene Peroxide-crosslinked polyethylene is designated PE-Xa.
Page 9 EDGE fitting components - All fittings and compression sleeves for EDGE can be used for water services. - Do not combine EDGE fittings or compression sleeves with components from other ranges. - Please note the dimensions of the fittings and compression sleeves.
Page 10: Installation Tools
Able to compress sizes 16-32mm When using A-Light2 tool, use only compression When using L1 tool, use only compression jaws that jaws that are specifically approved for EDGE are specifically approved for EDGE Sleeves and Sleeves and Fittings (black colour).
Page 11 When cutting EDGE pipes, observe the following: • Cut the pipe square and without burrs. • Pipe cutters must be in good working condition. Approved pipe cutters for EDGE pipe: EDGE Silver Hot and cold water pipe Pipe Dimensions Hot water pipe...

Page 14 After insertion, check the correct insertion depth via the Place the tool jaws over the pipe, so that it is in firm inspection windows.
Page 15: Installation Guidelines - General
• Do not extend the leverage of installation tools, e.g with pipes Compatibility of different thread types • Only the following thread types may be used with the REHAU EDGE system: Sealing threads in accordance with ISO 7-1 (AS 1722.1) and EN 10226-1:...

Page 22 6.7.1 Calculating thermal length changes the system. The effects of this stress can be mitigated by using deflection legs. EDGE PE-Xa pipes are particularly Due to the changing operational temperatures, especially suitable for this due to their flexibility.
Page 23 6.7.2 Deflection legs Do not fit pipe support channels or pipe brackets A deflection leg is the freely moveable pipe length, which on deflection legs as this would restrict their can take up the required thermal length changes. The flexibility. length of the deflection leg is influenced mainly by the material (material constant C).
