Installation and electrical connection 7.2 Installation en The pump must be installed in a dry, well-ventilated and frost-free place. CAUTION Possible damage of the pump! Dirt and solder drops in to the pump body can effect the pump operation. • It is recommended that any welding and soldering work be done before installing the pump. • Thoroughly flush the system out before installing the pump. ƒ The pump must be installed in an easily accessible position to facilitate inspection or replacement.
en Installation and electrical connection WARNING Risk of fall! The pump must be never carried by using motor hooks: these are only designed to lift the motor alone. 7.3 Pipe connection ƒ Connect the pump to the pipes by using appropriate counterflanges, bolts, nuts and gaskets. CAUTION Tightening of screws or bolts must not exceed. Configuration PN16 / PN25 M10 – 20 N.m - M12 – 30 N.m Configuration PN40 M12 – 50 N.m - M16 – 80 N.m Use of impact wrench is prohibited.
Commissioning 7.5 en Electrical connection WARNING Electrical shock hazard! Dangers caused by electrical energy must be excluded. • Electrical work by a qualified electrician only! • All electrical connections must be performed after the electrical supply has been switched off and secured against unauthorized switching. • For safe installation and operation a proper grounding of the pump to the power supply’s grounding terminals is required.
en Commissioning WARNING Risk of scalding! When the pumped liquid is hot and the pressure high, the stream escaping at the venting screw may cause burns or other injuries. ƒ Open the guard valve on the suction side completely (2). ƒ Start the pump and check if direction of rotation matches the one printed on pump plating. If this is not the case, interchange two phases in the terminal box.
Maintenance en WARNING important noise Noise emitted by most powerful pumps could be very high : protection must be used in case of long stay close to the pump. CAUTION Possible damage of the pump Installation must be designed in order that no one could be hurt in case of fluid leakage (mechanical seal failure …). 9 Maintenance All servicing should be performed by an authorized service representative! DANGER Electrical shock hazard! Dangers caused by electrical energy must be excluded.
en 10 Faults, causes and remedies Faults, causes and remedies DANGER Electrical shock hazard! Dangers caused by electrical energy must be excluded. All electrical work must be performed after the electrical supply has been switched off and secured against unauthorized switching. WARNING Risk of scalding! At high water temperatures and system pressure close isolating valves before and after the pump. First, allow pump to cool down.
