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.

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.

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 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.

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. Custom

control panels are available in many different configura-

tions. Custom panel quote requests may be forwarded to

Customer Service through any authorized distributor.
Our duplex panels feature a solid-state printed circuit board

design with standard high level alarm circuits. Other stan-

dard features are: an auxiliary dry alarm contact for signal-

ing 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 la-

bor 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
