SINGLE PHASE PUMPS
Single phase (1Ø) 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 5.
All
1
/
and ½ HP , 115 or 230 volt pumps, and some ¾
3
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 5.
WARNING
PLUG-CONNECTED UNITS MUST
BE CONNECTED TO A PROPERLY
GROUNDED, GROUNDING TYPE
RECEPTACLE.
ON NON-PLUG UNITS, DO NOT RE-
MOVE CORD AND STRAIN RELIEF.

cause death.
Pumps with bare lead power cords can be hard-wired
to a float switch, wired to a 1Ø 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 waste water pumps contain on-wind-
ing overloads, unless noted on the pump nameplate. See
Figures 1 and 2.
SINGLE PHASE CONTROL PANELS:
Control panels are available as Simplex (controls 1
pump) or Duplex (controls 2 pumps). Our standard
control 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 op-
tions than the standard 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 standard duplex panels feature a solid-state printed
circuit board design with standard high level alarm cir-
cuits. Other standard features are: an auxiliary dry alarm
contact for signaling a remote alarm and float switch po-
sition indicator lights. Most standard panels are in stock
for immediate delivery.

STANDARD PUMP INSTALLATION
Connect the pump(s) to the guide rail pump adapters
or to the discharge piping. Guide rail bases should be
anchored to the wetwell floor.
Complete all wiring per the control panel wiring dia-
grams and NEC, Canadian, state, provincial and/or local
codes.
DO NOT PLACE HANDS IN PUMP

operate freely and will not contact the
piping.
PRE-PACKAGED SYSTEM INSTALLATION
Connect the piping per local codes and the drawings in
Typical Drawings Section.
Sink Drain Systems – Inspect unit for damage. Return
damaged units to the distributor. Install on solid, level
ground. Hand tighten the piping into the Inlet. Con-
nect the Discharge to the main drain line. The discharge
should contain a union and a check valve. See Typical
Installation Drawing 2.
Packaged Sewage Systems – Inspect unit for damage.
Return damaged units to the distributor. Install on solid,
level ground. Remove all tape from discharge pipe, vent
hole, float switch and inlet. Check to insure that the float
swings freely and is attached to the pump. Install the
grommet in the inlet hole and lubricate it before install-
ing the inlet pipe. Connect the vent per code. If installing
outdoors protect the unit from freezing. Install a union
and check valve per valve manufacturer's instructions.
Install a gate valve on the discharge side of the check
valve for plumbing maintenance. See Typical Installation
Drawing 1.

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. Note: Small package systems will normally have
a fast ON-OFF cycle.
Control Panel Operation – Fill the wetwell with clear
water.
Use the pump H-O-A (Hand-Off-Automatic) switches
in Hand to test the pumps. If they operate well in Hand
proceed to test Automatic operation. If the pumps run
but fail to pump, they are probably air locked, drill the
relief holes per the instructions in the Piping Section.
Place Control Panel switch(es) in Automatic position and
thoroughly test the operation of the ON, OFF, and Alarm
floats by filling the wetwell with clear water. Important:
Failure to provide a Neutral from the power supply to
a 1Ø, 230 volt Control Panel will not allow the panel
control circuit to operate. The Neutral is necessary to
complete the 115 volt control circuit.
Check voltage and amperage and record the data on the
front of this manual for future reference. Compare the
amperage readings to the pump nameplate maximum
amperage. If higher than nameplate amperage investigate
cause. Operating the pump off the curve, i.e. with too
little head or with high or low voltage will increase am-
perage. The motor will operate properly with voltage not
more than 10% above or below pump nameplate ratings.
Performance within this range will not necessarily be the
same as the published performance at the exact rated
nameplate frequency and voltage. Correct the problem
before proceeding.
