SINGLE PHASE PUMPS Single phase (10) pumps may be operated using a piggy- back or hard wired float switch, a contactor, or a Simplex or Duplex control panel. See Figures 1, 2 and S. All 1/3and '/z HP, 115 or 230 volt pumps, and some 3/a and 1 HP pumps, are supplied with plug style power cords. They may be plugged into piggyback float switches for simple installations. It is allowable to remove the plugs in order to hardwire or connect to a Simplex or Duplex controller. Removing the plug neither voids the warranty nor violates the agency Listings. See Figure S. AWARNING PLUG -CONNECTED UNITS MUST 0 BE CONNECTED TO A PROPERLY —� GROUNDED, GROUNDING TYPE RECEPTACLE. ON NON -PLUG UNITS, DO NOT REMOVE CORD AND STRAIN Hazardous voltage RELIEF. DO NOT CONNECT can shock, bum or cause death. CONDUIT TO PUMP. Pumps with bare lead power cords can be hard -wired to a float switch, wired to a 10 contactor, a Simplex controller or a Duplex controller. Always verify that the float switch is rated for the maximum run amperage, maximum starting amperage, and the HP rating on the pump. Single-phase wastewater pumps contain on -wind- ing overloads, unless noted on the pump nameplate. See Figures 1 and 2. THREE PHASE PUMPS: As a Minimum a 30 pump requires a 3 pole circuit breaker/fused circuit, an across the line magnetic starter ( rated for the pump HP, and ambient compensated Quick Trip Class 10 overloads. SINGLE AND THREE PHASE CONTROL PANELS: Control panels are available as Simplex (controls 1 pump) or Duplex (controls 2 pumps). Our standard SES Series Panels are available with many standard features and can be built with our most popular options. We also custom build panels which offer many more design options than the SES panels. Custom control panels are available in many different configurations. Custom panel quote requests may be forwarded to Customer Service through any authorized distributor. Our "SES" Duplex panels feature a solid-state printed cir- cuit board design with standard high level alarm circuits. Other standard features are: an auxiliary dry alarm con- tact for signaling a remote alarm and float switch position indicator lights. Our 30 panels have built-in, adjustable, Class 10 overloads. The adjustable overloads on all our 30 panels mean less labor for the installer and no need to order specific overloads. Most SES panels are in stock for immediate delivery. On pumps equipped with seal fail and/or heat (high temperature) sensors it is recommended that you use our control panel with the appropriate options. The pump sensors do not function without a seal fail relay or termi- nal connection in the control panel and a warning device such as a bell, horn or light. Seal Failure Circuit - Some dual seal pumps are equipped with a standard, built-in seal failure circuit, which may also be called a moisture detection circuit. This circuit must be connected to a control panel with an optional seal fail relay. The panel must be special ordered with the seal fail relay and alarm. There are also stand alone seal fail panels such as the A4-3 or A44 available as standard items. The pumps can be identified by an extra control cable exiting the motor cover. The cable contains two wires, a black wire, connects to panel "terminal" going to "probe"; and a white wire, connects to the panel "terminal' going to the relay ground. Do not connect to the panel ground screw. Follow the wiring instructions supplied with the panel. Heat Sensor and Seal Failure Circuit - Some pumps are equipped with a seal fail and normally closed, on -wind- ing high temperature thermostats (heat sensors). The pumps have a control cable with four (4) leads, black (probe) and green (relay ground) for the seal fail circuit and red and white for the high temperature circuit. Con- nect the high temperature (heat sensor) circuit to the panel terminal strip as indicated on the panel drawing us- ing the red and white wires. The high temperature panel circuit is also an optional item which you must specifi- cally order when you order your control panel. The high temperature circuit is different from the Class 10 over- loads which are always required on three phase pumps. Follow the wiring instructions supplied with the panel. INSTALLATION Connect the pump(s) to the guide rail pump adapters or to the discharge piping. Slide rail bases should be an- chored to the wetwell floor. Complete all wiring per the control panel wiring dia- grams and NEC, Canadian, state, provincial and/or local codes. This a good time to check for proper rotation of the motors/impellers. DO NOT PLACE HANDS IN PUMP SUCTION WHILE CHECKING MOTOR ROTATION. TO DO SO WILL CAUSE SEVERE PERSONAL INJURY. Always verify correct rotation. Correct rotation is indicated on the pump casing. Hazardous Machinery Three phase motors are reversible. It is allowable to bump or jog the motor for a few seconds to check impeller rota- tion. It is easier to check rotation before installing the pump. Switch any two power leads to reverse rotation. Lower the pump(s) into the wetwell. Check to insure that the floats will operate freely and not contact the piping. OPERATION Once the piping connections are made and checked you can run the pumps. Piggyback Switch Operation — Plug the piggyback switch into a dedicated grounded outlet and then plug the pump into the switch. Test the pump by filling the wetwell until the pump goes On. If the pumps run but fail to pump, they are probably air locked, drill the relief holes per the instructions in the Piping Section. Check the operating range to insure a minimum one min- ute run time and that the pump goes Off in the correct position. Control Panel Operation — Fill the wetwell with clear water.
