SINGLE PHASE PUMPS
Single phase (1Ø) pumps may be operated using a piggy-
back or in conjunction with, or a Simplex or Duplex control
panel. See Figures 1, 2 and 5.
Most / and ½ HP , 115 or 230 volt pumps, and some ¾
1
3
and 1 HP pumps, are supplied with plug style power cords.
They may be plugged into piggyback float switches for sim-
ple 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.

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
wastewater pumps contain on-winding overloads, unless
noted on the pump nameplate. See Figures 1 and 2.
THREE PHASE PUMPS:
As a Minimum a 3Ø 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. Custom con-
trol panels are available in many different configurations.
Custom panel quote requests may be forwarded to Custom-
er Service through any authorized distributor.
Our duplex panels feature a solid-state printed circuit
board design with standard high level alarm circuits. Other
standard features are: an auxiliary dry alarm contact for
signaling a remote alarm and float switch position indicator
lights. Our 3Ø panels have built-in, adjustable, Class 10
overloads. The adjustable overloads on all our 3Ø pan-
els mean less labor for the installer and no need to order
specific overloads. Most panels are in stock for immediate
delivery without options.
Heat Sensor and Seal Failure Circuit - Some Pumps are
equipped with a seal failure circuit and a Heat sensor. On
standard product the seal failure circuit, if supplied without
Heat sensor will have an extra lead from the motor with
two conductors. These leads will be Black and White and
should be connected to the seal failure terminals in a panel
supplied with this option. If a seal failure circuit and Heat
sensor are supplied with the pump there will be a separate
lead with four conductors. For these leads the connection
for seal failure will be Black and Green and the Heat sensor
will be Red and White. The model 1GD/12GDS can be or-
dered with an optional seal failure circuit, but most dual seal
pumps come with the seal failure circuit as a standard.
Models with a 4NS/4DWC/4XD/4XWS have a standard
configuration with seal failure and heat sensor. The leads
are in a separate jacket with 5 leads. Black (tagged P1) and
White (tagged P2) should be connected to thermal protec-
tion terminals. The seal fail leads are Red (tagged W1) and
Orange (tagged W2) and should be connected to the seal
fail terminals. The additional lead is Green and should be
connected to Ground. Panels will come equipped with a
wiring diagram designating your connections. Panels must
be ordered with the options for seal failure circuits and heat
sensor circuits, since these panels can also be used on pumps
without the option for these connections they do not come
as standard on most panels.
One additional style of seal failure and heat sensor circuits
is our product sold with models GA(X) / 15GDS(X) /
20GDS(X); 2, 3, 4GV(X); 2, 3, 4MV(X); 2, 3, 4, 6MK(X).
These units come with a single lead for power and controls.
The conductor will come with 7 leads (previous to January
2013). Leads For seal failure and heat sensor will be Orange
and Blue. Since these units use a different style sensor in the
pump as well as a different option in the panel the connec-
tions require only two leads. After January 2013 the lead
colors on the pumps were changed to two (2) white leads
for the seal failure and heat sensor.
Be careful to choose the correct options in the panel selec-
tion for each style pump. Always follow wiring schematic
of the panel. Failure to wire the seal failure and heat sensor
leads correctly may prevent the pump from running or
cause nuisance tripping.

INSTALLATION

Connect the pump(s) to the guide rail pump adapters or to
the discharge piping. Slide rail bases should be anchored to
the wetwell floor.
Complete all wiring per the control panel wiring diagrams
and NEC, Canadian, state, provincial and/or local codes.

tors/impellers.

few seconds to check impeller rotation. 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 instruc-
tions in the Piping Section.
Check the operating range to insure a minimum one minute
run time and that the pump goes Off in the correct position.
Control Panel Operation – Fill the wetwell with clear water.
