4. D arrange for proper conditions for suction and discharge valve closing during disassembly E make sure that the motor is completely disconnected during disassembly Proper design and building of the plants with well positioned and well marked piping fitted with shut off valves adequate passages and work areas for maintenance and inspections are extremely important since the pressure developed by the pump could give some kind of damage to the plant in case this one should be faulty made or wear and tear damaged It must be stressed that the major cause of pump failures leading to a consequent need to intervene is due to the pump running dry in manually operated plants This is generally due to the suction valve being closed at start up or the suction tank being emptied without stopping 1 1 Installation and commissioning personnel Interventions allowed only to specialised personnel who may eventually delegate to others some operations depen ding on specific evaluations technical capability required specialisation in industrial plumbing or electric systems as needed 1 2 Operators and maintenance personnel Interventions allowed to general operators after training on the correct use of the plant pump starting and stopping opening and closing of valves with the pump at rest emptying and washing of the pump body via special valves and piping e cleaning of filtering elements Interventions by qualified personnel t
