Instruction manual Installation37Type „Radial installation and removal“: Loosen the coupling nut and slide it on the intended pipe end. Connect the connection parts with the pipe ends. For instructions concerning the differentconnection types, see planning fundamentals. Put pressure reducing valve type 582/pressure retaining valve type 586 between theconnection parts. Tighten the coupling nuts by hand.„Spigot ends“: If adapted to flange version, observe the tightening torques of the flanges, see „GeorgFischer planning fundamentals“.In order to protect against soiling and premature wear and tear by erosion, werecommend installing a strainer on the inlet side of pressure reducing valve type582/pressure retaining valve type 586.Cemented connection Only join identical materials. After the curing time of the joint has elapsed, rinse the pipe section as quickly as possiblewith pressure-less water, see Chapter „Jointing techniques” in the „Georg Fischerplanning fundamentals”Welded connection Only join identical materials, see Chapter „Jointing techniques” in the „Georg Fischerplanning fundamentals”.
