(FIGURE 3-2 ) <br /> 1 . 1 Pump Operation 1 .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 />
