On Float(middle float)15"from centerline of inlet to float cord. <br /> 3.) Off Float(lowest float)13"from bottom of basin to float cord. <br /> Notes for adjusting these levels: <br /> I, t <br /> 1.) Do not raise the alarm float higher than 9"below the inlet centerline or fluid will start <br /> j t backing up the inlet line prior to alarm activation. <br /> " 2.) Do not lower the"off'float below the 13"minimum.Pump shutoff needs to occur <br /> r. while the impeller is still submersed In fluid to prevent air entering the impeller cavity. <br /> I l 3.) Maintain at least a 6"minimum differential between the bottom of the"Alarm"float <br /> and the bottom of the"On"float. <br /> ENSURE THAT 4.)The"On"float can be lowered or the"Off'float raised to reduce the volume per pump cycle. <br /> RUBBER 5.)We do not recommend adjustments of more than 3"In either direction--please call the <br /> GROMMET IS Factory if you need to adjust the pump cycle beyond this recommended level. <br /> i PROPERLY <br /> INSTALLED HERE <br /> ®Copyright 2016 Liberty Pumps Inc.
