the pump must be installed in a dry well-ventilated place with an ambient temperatures of no more than 40 +A . Fix the pump in place on a sold flat surface using suitable bolts to avoid vibration. the pump be installed in horizontal position to ensure that the bearings operate operate correctly. the diameter of the intake pipe must not be smaller than that of the intake mouth. if the intake height exceeds 4 meters, use a pipe with a larger diameter. the diameter of the delivery pipe must be chosen to suit the flow rate and pressure required at the takeoff points. the intake pipe must be slightly angled up towards the intake mouth to avoid the formation of air lacks +B . make sure that the intake pipe is completely airtight and immersed in the water by at least half a meter to avoid the formation of vortexes. Always fit a foot valve at the end of the intake pipe. it is advisable to fit a non-return valve between the delivery-month and flow rate adjustment gate value to avoid dangerous water hammering in the event of the pump suddenly stopping.this measure is compulsory if the delivery water column is over 20 meter.
