Installation and operating instructions Date: 3 July 2013 Central Heating System Document no: 3392041C - EN Hoses and pipelines An installation that is installed with copper or plastic lines (Hep2O) could be chosen. Webasto can also supply pre-insulated Hep2O lines. If hoses are used they must comply with DIN73411 at least. The hoses must be kink-free and be installed on a rise for automatic bleeding where possible. Hose connections must be fixed with hose clamps.
Installation and operating instructions Date: 3 July 2013 Central Heating System Document no: 3392041C - EN The proper working of a water system depends on several basic principles which apply to every installation: • • • The temperature difference “coolant in – coolant out” must be no more than 15°C, measured at the heat exchanger, a larger temperature difference indicates too little circulation caused by too much resistance in the heating circuit; this could result in overheating or even in the heat
