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 / and ½ HP , 115 or 30 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.

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-wind-
ing 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  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 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 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 A4-4 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.

Three phase motors are reversible. It is
Hazardous Machinery
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.
