1. ENGLISH ENGLISH 1 GENERAL WARNINGS Read this manual carefully before installing this pump It contains every necessary information for installation correct use and maintenance of AQUALIJU pumps It s very important that the user reads this manual before using the pump Any damage caused by failure to observe the directions contained in this manual will not be covered by warranty By the time you receive this pump check if it wasn t damaged during transpor tation In this case please contact our agent as soon as possible 2 DANGER ELECTRIC SHOCK RISK Do not use in ponds tanks or swimming pools when people may enter or come into contact with the water Make sure that the pump is switched off before installation or maintenance operations The unit must always be earthed in accordance with local legislation Never use the electric power cable to suspend or transport the pump CAUTION Ifthe electric cable or has become damaged please contact our agent before any intervention with the pump 3 OPERATING CONDITIONS Pumps from AQUALIJU series are suitable for Clean water with a maximum temperarure of 35 C and a maximum sand content of 60 g m Minimum internal diameter of well 115 mmAJ Minimum immersion depth 200 mm Maximum submersion depth 20 m with suitable cable length Maximum starts hour 30 atregular intervals The electropump cannot be used2. to move dangerous or inflammable Ki liquids This pumpis not for portable use Switch off this pump every time you transport it 4 INSTALLATION Never use the electric power A cable to suspend the pump Avoid dry running 4 1 PUMP INSTALLATION IN THE RESTING POSITION TANKS The pump can be rested on the flat botton surface of a tank but when sand or particles of sediment are present it s advisable to mount the pump on a surface raised from the bottom level so that abrasive matter is not lifted 4 2 PUMP INSTALLATION IN THE SUSPENDED POSITION WELL The pump can be held in a suspended position by the metal delivery pipe Tighten the threaded pipe joints firmly to avoid loosening during operation Position the pump at a distance of at least 0 5m from the bottom of a well so that sand is not lifted fig 1 When a plastic or flexible delivery pipe is used a nylon safety rope or chain should be utilized for lowering securing and raising the pump Attach the power supply cable to the delivery pipe and to the safety rope with cable clamps at intervals of about 3 m The power cable should not be taut It must allow a certain degree of slackness between the clamps to avoid the risk of strain caused by expansion of the pipe during operation Protect the electric power cable from contact with the well wall to prevent damage WARNING It is advisable to install a gate valve at the
