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, con-
nects 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-winding
high temperature thermostats (heat sensors). The pumps
have a control cable with five (5) leads, black (P1) and white
(P2) for the seal fail circuit and red (W1) and orange (W2)
for the high temperature circuit. Grean lead is ground. Con-
nect the high temperature (heat sensor) circuit to the panel
terminal strip as indicated on the panel drawing using the
red and orange wires. The high temperature panel circuit
is also an optional item which you must specifically order
when you order your control panel. The high temperature
circuit is different from the Class 10 overloads which are
always required on three phase pumps. Follow the wiring
instructions supplied with the panel.
*4NS NOTE: Call Technical support for wiring of
4NS/4XD/4XWS/4DWC/2GA/1GA/15GDS/20GDS.
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.
This a good time to check for proper rotation of the mo-
tors/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.
Three phase motors are reversible. It is
allowable to bump or jog the motor for a
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.
SINGLE PHASE PUMPS
Single phase (1Ø) pumps may be operated using a pig-
gyback or hard wired float switch, a contactor, or a Simplex
or Duplex control panel. See Figures 1, 2 and 5.

and ½ HP, 115 or 230 volt pumps, and some ¾ 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.
PLUG-CONNECTED UNITS MUST
BE CONNECTED TO A PROPERLY
GROUNDED, GROUNDING TYPE
RECEPTACLE.
ON NON-PLUG UNITS, DO NOT
REMOVE CORD AND STRAIN RELIEF.
DO NOT CONNECT CONDUIT TO
PUMP.
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 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
circuit 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 3Ø panels have built-in, adjustable,
Class 10 overloads. The adjustable overloads on all our 3Ø
panels mean less labor for the installer and no need to order
specific overloads. Most SES panels are in stock for immedi-
ate delivery.
On pumps equipped with seal fail and/or heat (high temper-
ature) 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 terminal 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 A4-4 available as standard items. The pumps
