GENO®-DK-Maxi (nominal connection diameter DN 150 to 250) are system separators according to construction design BA of DIN EN 12729. When special withdrawal points and apparatus are connected to the drinking water supply, they guarantee water quality in accordance with DIN EN 1717, up to and including hazard class 4. The Euro system separator prevents the backflow, back pressure and return suction of modified drinking water into the drinking water installation. GENO®-DK-Maxi replace pipe separators EA 1 and EA 2 and are manufactured from coated nodular cast iron. The safety devices are suitable for operating temperatures of up to 60°C at PN 10 bar. They work according to the 3-chamber system, subdivided into an inlet pressure zone, central pressure zone and rear pressure zone. The system separators have a flange connection (DIN EN 1092-1) for horizontal installation, two non-return valves and dripping water connection as well as three test connection pieces.
Local installation directives, general guidelines and technical specifications of the Euro system separator must be observed. The installation site must be accessible for maintenance work, flood and frost-proof and ensure that the system is protected from chemicals, dyes, solvents and vapours. As per DIN 1988 and DIN EN 1717, the system separator has to be protected from impurities by means of appropriate devices such as a fine filter. If there is chance that deposits might come free of the pipes, the fine filter must be installed directly upstream of the system separator.
Euro system separator, ready for installation and operation, without counter flange and seals, with operation manual, packed in a cardboard box.
