Via per Alzo 39, 28017 San Maurizio d’Opaglio (NO) Italia  consulenza.prodotti@giacomini.com  +39 0322 923372 - giacomini.com Setting and balancing of hydraulic circuits on supply manifold The system single circuits must be set using the regulation lockshields on the supply manifold. The lockshields feature mechanical memory which, once adjusted, enable to set a mechanical lock to restore the settings after full or partial shutting-off. The mechanical memory is made by a ring which, adjusted with the R558 wrench, enables to limit the lockshield maximum opening to the value selected during balancing. For proper setting of the lockshield, unscrew the metal ring all the way through using the screwdriver side of the R558 wrench, then tighten the lockshield completely using the hex side of the wrench. Open the lockshield by the number of turns desired based on the diagram for setting the loss of pressure, then screw the memory ring on till it is flush with the lockshield. R473 R473M R453F R473 R473M R453F R473 R473M R453F R473 R473M R453F Circuit pipe connection To connect the circuit water supply pipes, use Eurocone adaptors for copper, plastic or multilayer pipes series R178E or R179E.  WARNING. Use a 26 mm back wrench when screwing/unscrewing the adaptors to the manifold outlets.  Installation and setting Installation of terminal units First screw the intermediate fitting (A) on the manifold. Then install the drain cock (B) on the bottom of the intermediate fitting and the air vent valve (C) on top. All components are provided with self-sealing gasket. A B C Max. 25 Nm 5 Nm 5 Nm A B C  WARNING. Installation must be carried out by qualified operators according to the instructions below. Shutting off the hydraulic circuits on the return manifold Turn the provided blue handwheels all the way through to shut off the circuits on the return outlets. As an alternative, thermo-electric actuators can be installed on the M30 x 1,5 mm standard connection. To install the R473/R473M thermo-electric actuators normally closed, replace the blue handwheels with R453FY002 quick-fit ring nuts. Install the thermo-electric actuator of the ring nut using enough pressure to fit it. Turn the thermo-electric actuator slightly to properly connect it to the ring nut (max. torque 5 Nm).
