INSTALLATION & MAINTENACE MANUALRCOe2100/03.06304.2 – Hydraulic Connections4.2.1 – Main Inlet Hoses ConnectionsIn standard configuration, the motor has two ports on the rotary valve housing which may be both inlet oroutlet ports depending on the application, and 6 threaded holes.Remove the plastic plugs from the inlet ports before connecting the hoses.Standard Parker Calzoni threaded holes or SAE flanges (pls. refer to the “Technical Catalogue”) are suppliedupon request: these flanges have grooves for the sealing gaskets (O-Rings).In case the application foresees rigid pipes, they must be made in drawn, polished steel and must beconnected to the flange by means of cutting-ring fittings (such as ERMETO).We recommend not to use welded pipes; should it be necessary to use them, they must be internallycleaned thoroughly around the welds using both mechanical means and chemical pickling so that to preventwelding residue from entering the oil circuit.Steel pipes must be chemically pickled and then neutralised and flushed when they show traces of oxidationor in any case they are not perfectly clean.4.2.2 – Drain Line ConnectionsThe motor drain line must be connected directly to tank (without filter) by means of an ø 1/2" or ø 3/8" sizepipe, not too long and without unnecessary bends and bottlenecks. Pressure inside the motor case must notexceed 5 bars to prevent damaging the shaft seal or 15 bar if the motor is equipped with a high pressureshaft seal.In order to avoid the motor case emptying, the drain line connection must be executed according to thefollowing instructions:HorizontalInstallationUse the drain port located in the highest position to ensure the perfect lubrication of thetwo motor bearings.
