(FIGURE 3-2 ) <br /> 1 . 1 Pump Operation l .The level of the wastewaters rises to <br /> the first stage of the Kari float <br /> switch. The Hari float switch <br /> energizes one of the self priming <br /> centrifugal pumps . (FIGURE 3-1 ) <br /> 2 . If the first pump fails to hold the <br /> water level down, the wastewater level <br /> reaches the second stage of the Kari <br /> float switch which energizes the second <br /> pump. <br /> 4 <br />
