Concealed installation should be good for pipe installation in duct, floor or embeded in wall.
Open installation shouldn't be used for pipe installation outside. if necessary, the protection should be used to prevent outdoor pipe from UV, frost, etc.
Water supply pipe in open installation cann't go through bedroom, stock, switchroom, smoke way, wind way and especially far beyond thermal rescource. Riser is at least 200mm away from water heater, thermal resource.

Fastening Techenique

Pipe clamps for dismy-pipes have to correspond to the external diameter of the plastic pipe Furthermore it is important, that the fastening material does not damage the surface of the pipe mechanically. The ideal fastening material for PPR Pipes are rubber lined pipe clamps.The rubber compound is specially made for applications with plastic pipes. The selection of the fastening material and its application has to be determined as a

Fixed Points

• On locating fixed points the pipelines are devided into individual sections.This avoids uncontrolled movements of the pipe.
• ln principal fixed points have to be measured and installed in a way,that the forces of expansion of dismy-pipesas well as probable additional loads are absorbed.
• On using threaded rods or threaded screws the drop from the ceiling should be as short as possible.
• Rocker supports should not be used as fixed points.
• It is always possible to install vertical distributions rigidly. Risers do not require expansion loops,provided that fixed points are located immediately before or after a branch.
• On locating fixed points the pipelines are divided into individual sections. The sufficient fixed points and supports have to be installed in order to compensate linear expansion of pipe.

Sliding Points

• Sliding clamps have to allow axial movements of the pipe without damage.
• On locating a sliding clamp it has to be observed that movements of the pipelines are not hindered by fittings or armatures installed next to them.
