8. Time When the pump has been connected correctly the pump should be started with the discharge valve closed approximately one third Due to the soft start feature the pump takes approximately 2 seconds to develop full pressure Motor Cooling and Other Considerations Make sure the well is capable of yielding a minimum quantity of water corresponding to the pump capacity Do not start the pump until it is completely submerged in the liquid As the valve is being opened the drawdown should be checked to ensure that the pump always remains submerged To ensure the necessary cooling of the motor the pump should never be set so low that it gives no water If the flow rate suddenly falls the reason might be that the pump is pumping more water than the well can yield Water Impurities lf there are impurities in the water the valve should be opened gradually as the water becomes clearer The pump should not be stopped until the water is clean otherwise the pump parts and the check valve may become clogged When the water is clean the valve should be fully opened Minimum flow rate Note Note To ensure the necessary cooling of the motor the pump flow rate should never be set to a value lower than 2 gpm If the flow rate suddenly falls the reason might be that the pump is pumping more water than the well can yield The pump s dry running protection is effective only within the recommended duty range of the pump Do n
