i <br /> PRE-INSTALLATION CHECKLIST <br /> 1.PREINSTALLATION <br /> Well Preparation <br /> If the pump is to be installed in a new well then the well should be fully <br /> developed and bailed or blown free of cuttings and sand.The construction <br /> ofthe GRUNDFOS SOJSOE submersibles makes it resistant to abrasion; <br /> however, no pump made of any material <br /> can forever withstand the destructive wear <br /> i that occurs when constantly pumping <br /> zid <br /> sa ndy water. x, <br /> If this pump is used to replace an oil-filled <br /> submersible or oil-lubricated line-shaft <br /> turbine in an existingwell,the well must <br /> \; , <br /> be blown or bailed clear of oil. <br /> Make Sure You Have the Right Pump <br /> Determine the maximum depth of the well, <br /> and the drawdown level at the pump's <br /> maximum capacity.Pump selection and Pump <br /> setting depth should be made based on <br /> this data. <br /> Motor <br /> Pumped Fluid Requirements <br /> Submersible well pumps are designed for <br /> pumping clear,cold water;free of air or ILDJ <br /> gases.Decreased pump performance and Figure i <br /> life expectancy can occur if the water is not dear,cold <br /> or contains air or gases.Water temperature should not exceed 104°F. <br /> A check should be made to ensure that the installation depth of the pump <br /> will always be at least three feet below the maximum drawdown level of <br /> the well.The bottom of the motor should never be installed lower than the <br /> top the screen or within five feet of the well bottom,as shown in Figure 1. <br /> Motor Cooling Requirements <br /> To ensure proper motor cooling refer to the table below for <br /> minimum flow requirements: <br /> � I <br /> i <br /> FLOW VELOCITY MAXIMUM <br /> j PAST THE MOTOR LIOUiD TEMPERATURE <br /> 0.0 f/s °C30 <br /> °F <br /> (free convection) 86F(30-C) <br /> i Min.0.5 f/s 104°F(40°C) <br /> j <br /> r <br /> i <br /> z l <br />
