rigorous hydraulic and electrical controls, painstakingly verified. By strictly following the instructions for the installation and use of the pump paying careful attention to the wiring diagrams you shall avoid the possibility of overloading the motor or of any other problems that might otherwise arise from misuse, for which we can accept no responsibility. 2. Installation The pump should be attached to a solid base, bolting it through the bolt holes in the mounting, thus eliminating the possibility of any unnecessary noise or vibration. The pump should be fitted as near as possible to the water level to make the suction head as low as possible. The pump should be fitted where it will remain safe from flooding and should be ventilated with dry air. 3. Mounting the pipework The diameter of the suction pipe should be equal to or greater than the pump intake and should be set at a gentle slope of a least 2% to facilitate adequate purging. The foot valve must remain at least 30 cm below the water line, thus avoiding whirlpools and the risk of air entering the system. The discharge pipe should be of a diameter equal to or greater than that of the pump discharge. As the pipe used is of a larger diameter, we shall use the corresponding eccentric cones on the aspiration side and concentric cones on the discharge side. Neither suction nor discharge piping should rest against the pump. 4. Electrical connection The electrical installation must have a multiple terminal system with a contact opening of a least 3 mm. The system is basically protected by a differential relay (I fn = 30 mA). The power cable should comply with EEC(2) standards or correspond to the H07 RN-F VDE 0250 specifications. The fuse of protection must be of 6 amp. Single pha...
