simplified installation instructions

Cut the multi-layer composite pipe to length perpendicular to its longitudinal axis. Remove burrs and chips.

Calibrate the pipe with a tool that has no sharp edges so as not to cut the plastic layer, as this could affect the pressure tightness (calibration tool).

Apply grease or an equivalent lubricant permitted for drinking water pipes to the end of the pipe so that the O-rings can be fitted more easily and remain elastic. Place the nut on the pipe. Place the sealing cone on the pipe. Push the pipe into the fitting as far as it will go.

Tighten the nut by hand as far as possible and then tighten with a suitable wrench.

Please note that you always use press fittings and pipes from the "winny al" system for your installation work.

A DVGW-approved and thus safe, sufficiently tested pipe connection always consists of both components, the pipe and the screw fitting tested with this pipe. If a fitting is processed with a "foreign" pipe, there is no guarantee of tightness and compatibility, as it is an untested and non-approved connection, even if both products are DVGW-approved.

With regard to the professional planning, installation, acceptance and management of the water supply, heating and sanitary systems, the following valid regulations must be observed: UNI EN 806 : 2088 e UNI 9182 : 2010

Please note that the installation of all "winny al" components must be carried out by a technically competent person. The installation must also be documented and stored in a pressure test protocol in accordance with the manufacturer's and legislator's specifications. The detailed installation instructions as well as the print test protocol can be downloaded from our homepage. Failure to follow these instructions may result in the rejection of any warranty claims.

Have fun screwing!
