General InformationSewage Pump Systems:Simplex SystemA simplex system consists of one pump,its control switch, and one basin. It isused in applications where less thansix toilets (units) are discharged intoa basin. The simplex unit is generallyoperated with a contactor to turnthe pump ON and OFF. The contactoris activated by a single pole floatswitch. The float switch is a wide-angledifferential switch that rises with theliquid level and turns the pump ON.As the liquid level decreases, the floatlowers and turns the pump OFF. Theswitch differential is 120º.Sewage Pump Systems:Duplex SystemA duplex system is used in applicationswhere more than six toilets (units) aredischarged into a basin. However, eachpump should be sized to handle the entireflow in case one pump fails. The duplexunit is controlled by a NEMA 1 controlpanel that has an automatic alternator,run lights, hand-off-auto switches, andan alarm bell. The duplex control panelis supplied with three float switches. Thefloats are to be positioned so that thelower float turns the pumps OFF. Thesecond float alternates turning first onepump ON and then the other pump ON.The third float will turn BOTH pumps ONin case one pump cannot handle the flow.The third float will also sound the alarm(which remains on until the system is reset).Functionally, the liquid in the basin risesand trips the first float, but the pumps donot turn ON. As the liquid level rises, ittrips the second float, activating one of thepumps. Once the liquid level recedes andno longer trips the second float, the pumpwill turn OFF. If the second float is trippedagain, the other pump will turn ON.If for some reason the liquid levelincreases past the second float and tripsthe third float, both pumps turn ON andtrips the alarm.Under normal circumstances, the firstpump will handle the flow after thesecond float is tripped. In those cases,the liquid level will recede until it dropsthe lower float. This action turns thepump OFF. The next time that the liquidlevel rises, the other pump turns ON. Thisalternates the pumps; this prevents lock-up and extends the lifer of both pumps.Available ControlsFor 115 volt only, a wide angle floatswitch can be supplied with a plug-thruseries plug.For 230 volt Simplex units, a NEMA 1Simplex Controller with a hand-off-autoswitch and run light can be supplied.This is supplied with a wide-angleswitch for automatic operation.For 230 volt Duplex units, a NEMA 1control panel can be supplied witha hand-off-auto switches, run lights,pump alternator, and an alarm bell.This is supplied with a three float switchsystem for automatic operation.2Operating Instructions and Parts Manualwww.waynepumps.comInstallationAlwaysdisconnectthe power source beforeattempting to install, service,relocate or maintain the pump.Never touch sump pump, pump motor,water or discharge piping when pump isconnected to electrical power. Never handlea pump or pump motor with wet hands orwhen standing on wet or damp surface orin water. Fatal electrical shock could occur.Some models of this product includea grounded plug for quick installationanywhere a grounded outlet isaccessible. Some models must beincorporated into the building’selectrical system. Models without plugsmust be connected to a groundedcircuit. The circuit should be equippedwith a ground fault interrupter device.All models without plug-in power cordssystems must be installed by a qualifiedelectrician. All models with a plug-inpower cords system should still have aqualified electrician inspect the outletbeing used to ensure proper wiring.The control switch is a wide-anglesystem which prevents short cycling ofthe pump motor and the consequentialproblems that short cycling can cause.The switch can be mounted on thedischarge pipe (just above the pumpdischarge flange). See illustrations forswitch mounting arrangements.Figure 1 - Simplex System Figure 2 - Duplex SystemGroundingBlade GroundedOutletPowerCordSwitchCordTEST RESETFigure 3
