NOTICE: INDICATES SPECIAL INSTRUCTIONS
WHICH ARE VERY IMPORTANT AND
MUST BE FOLLOWED.
THOROUGHLY REVIEW ALL INSTRUCTIONS AND
WARNINGS PRIOR TO PERFORMING ANY WORK
ON THIS PUMP.
MAINTAIN ALL SAFETY DECALS.
All qualied work must be performed by
a qualied technician. Always follow the
National Electric Code (NEC), or the Canadian Electric
Code, as well as all local, state and provincial codes. Code
questions should be directed to your local electrical in-
spector. Failure to follow electrical codes and OSHA safety
standards may result in electric shock, personal injury or
death, and equipment damage. Failure to follow man-
ufacturer’s installation instructions may result in electric
shock, re hazard, personal injury or death, damaged
equipment, provide unsatisfactory performance, and may
void manufacturer’s warranty.
Standard units are not designed for use in
any swimming pools, open bodies of water,
any water feature including ponds, fountains or waterfalls or
any application where a person can come into contact with
the water in which the pump is submerged. Standard units
are not designed for us with hazardous liquids, or where am-
mable gases exist. These uids and gases may be present
in containment areas.Tank or wetwell must be vented per
local codes. Failure to follow this warning may result in electric
shock, explosion, re hazard, personal injury or death.
Only pumps specically Listed for Class 1,
Division 1 are allowable in hazardous liquids
and where ammable gases may exist. See specic pump
catalog bulletins or pump nameplate for all agency Listings.
Disconnect and lockout electrical power
before installing or servicing any electrical
equipment. Many pumps are equipped with automatic
thermal overload protection which may allow an over-
heated pump to restart unexpectedly.
DANGER
WARNING
CAUTION
All three phase (3Ø) control panels for submersible
pumps must provide Class 10, quick-trip, overload
protection.
PRE-INSTALLATION CHECKS
Open all cartons and inspect for shipping damage.
Report any damage to your supplier or shipping carrier
immediately.
Important: Always verify that the pump nameplate
Amps, Voltage, Phase and HP ratings match your control
panel and power supply.
Many of our sewage pumps are oil-lled. If there are any
signs of oil leakage or if the unit has been stored for an
extended period check the oil level in the motor dome
and the seal housing, if so equipped.
Check the motor cover oil level through the pipe plug on
top of the unit. The motor chamber oil should just cover
the motor. Do not overll, leave room for expansion!
To check the seal housing oil level, where used, lay the
unit on its side with the ll plug at 12 o’clock. Remove the
plug. The oil should be within ½” (13mm) of the top. If
low, rell with an ASTM 150 turbine oil. Replace the plug.
You can source oil locally at motor repair shops. Typical
oil brands are: Shell Turbo 32, Sunoco Sunvis 932, Texaco
Regal R&O 32, Exxon Nuto 32 and Mobil DTE Light.
Check the strain relief nut on power cable strain assem-
blies. Power cables should be torqued to 75 in. lbs. for
#16 cables and 80 in. lbs. for all other cable assemblies.
Seal/heat sensor cables, where used, should be torqued
to 75 in. lbs.
Warranty does not cover damage caused by connecting
pumps and controls to an incorrect power source (volt-
age/phase supply).
Record the model numbers and serial numbers from the
pumps and control panel on the front of this instruction
manual for future reference. Give it to the owner or afx it
to the control panel when nished with the installation.
This product can expose you to
chemicals including Lead, which is known
to the State of California to cause cancer and birth
defects or other reproductive harm.

OPTIONAL GUIDE RAIL OR LIFT-OUT SYSTEM
In many efuent and sewage basins or lift stations it is
advisable to install the pump on a guide rail system or
on a lift-out adapter to facilitate installation and removal
for inspection and/or service. Most codes do not allow
personnel to enter a wetwell without the correct protec-
tive equipment and training. Guide rails are designed
to allow easy removal of the pump without the need
for entry into the wetwell or need to disturb piping. The
guide rail or lift-out adapter should locate the pump
opposite the inuent opening preventing stagnate areas
where solids can settle. The basin or pit must be capable
of supporting the weight of the pump and guide rail. The
pit oor must be at.
NOTICE: FOLLOW THE INSTRUCTIONS THAT ARE
PROVIDED WITH THE GUIDE RAIL ASSEMBLY.
PIPING
Discharge piping should be no smaller than the pump
discharge diameter and kept as short as possible, avoid-
ing unnecessary ttings to minimize friction losses.
Install an adequately sized check valve matched to the
solids handling capability of the pump to prevent uid
backow. Backow can allow the pump to spin back-
wards and may cause premature seal, bearing, shaft
wear. If the pump is turning backwards when it is called
on to start the increased torque may cause damage to
the pump motor and/or motor shaft.
Install an adequately sized gate valve AFTER the check
valve for pump, plumbing and check valve maintenance.
Important – Before pump installation. Drill a 3⁄16”
(4.8mm) relief hole in the discharge pipe. It should be
located within the wetwell, 2” (51mm) above the pump
discharge but below the check valve. The relief hole
allows any air to escape from the casing. Allowing liquid
into the casing will insure that the pump can start when
the liquid level rises. Unless a relief hole is provided, a
bottom intake pump could “air lock” and will not pump
water even though the impeller turns.
All piping must be adequately supported, so as not to
impart any piping strain or loads on the pump.
The pit access cover must be of sufcient size to allow for
inspection, maintenance and crane or hoist service.
WIRING AND GROUNDING
Important notice: Read Safety Instructions before
proceeding with any wiring.
Use only stranded copper wire to pump/motor and
ground.The ground wire must be at least as large as
the power supply wires. Wires should be color cod-
ed for ease of maintenance and troubleshooting.
Install wire and ground according to the National
Electrical Code (NEC), or the Canadian Electrical
Code, as well as all local, state and provincial codes.
Install an all leg disconnect switch where required by
code.
Disconnect and lockout electrical power before
performing any service or installation.
The electrical supply voltage and phase must
match all equipment requirements. Incorrect
voltage or phase can cause re, motor and control
damage, and voids the warranty.
All splices must be waterproof. If using splice kits
follow manufacturer’s instructions.
Select the correct type and NEMA grade
junction box for the application and lo-
cation. The junction box must insure dry,
safe wiring connections.
Seal all controls from gases present which
may damage electrical components.
FAILURE TO PERMANENTLY
GROUND THE PUMP, MOTOR AND
CONTROLS BEFORE CONNECTING
TO POWER CAN CAUSE SHOCK,
BURNS OR DEATH.
SELECTING AND WIRING
PUMP CONTROL PANELS AND SWITCHES
FLOAT SWITCH TYPES
There are two basic oat switch designs; single-action
and wide-angle. Single-action switches operate over a
range of 15º so they open and close quickly. Wide-angle
oats operate over a 90º swing with the tether length be-
tween the oat body and the pivot point controlling the
On-Off range. The design determines how many oats
are required with different systems or controls.
Floats may be normally open (NO) for pump down appli-
cations or to empty a tank. Normally closed (NC) switches
are used to pump up or to ll a tank.
A single-action control switch may be used only with a
control panel, never direct connected to a pump.
The wide-angle, pump down switches may be used as
direct connected pump switches or as control switches.
SETTING THE FLOAT SWITCHES
There are no absolute rules for where to set the oat
switches, it varies from job to job.
Suggested Rules to Follow:
All oats should be set below the Inlet pipe!
Off Float: Best: set so free hanging the water level is
always above the top of the pump (motor dome). Next
Best: set so the water level is not more than 6" below the
top of the pump.
On Float: set so the volume of water between the On
and Off oats allows pumps of 1½ HP and under to oper-
ate for 1 minute minimum. Two (2) HP and larger pumps
should run a minimum of 2 minutes. Basin technical
brochure states the gallons of storage per inch of basin
height.
Lag/Alarm Float(s): should be staggered above the
Off and On oats. Try to use most of the available stor-
age provided by the basin, save some space for reserve
storage capacity. Exact reserve may be called out by local
codes. See Diagrams and Charts in Float Switch Chart
Section.
PANEL WIRING DIAGRAMS
Our control panels are shipped with instructions and
wiring diagrams. Use those instructions in conjunction
with this IOM. Electrical installation should be performed
only by qualied technicians. Any problem or questions
pertaining to another brand control must be referred to
that control supplier or manufacturer.
ALARMS
We recommend the installation of an alarm on all Waste-
water pump installations. Many standard control panels
come equipped with alarm circuits. If a control panel is

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 ordered 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
conguration 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
protection 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 con-
nections. 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 cir-
cuits 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 differ-
ent style sensor in the pump as well as a different option
in the panel the connections 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
selection 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 oor.
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.
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 oats 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 lling the
not used, a stand alone high liquid level alarm is avail-
able. The alarm alerts the owner of a high liquid level
in the basin so they can contact the appropriate service
personnel to investigate the situation.
SINGLE PHASE PUMPS
Single phase (1Ø) pumps may be operated using a
piggyback or in conjunction with, or a Simplex or Duplex
control panel. See Figures 1, 2 and 5.
Most 1/3and ½ HP, 115 or 230 volt pumps, and some
¾ and 1 HP pumps, are supplied with plug style pow-
er cords. They may be plugged into piggyback oat
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 oat switch, wired to a 1Ø contactor, a Simplex con-
troller or a Duplex controller. Always verify that the oat
switch is rated for the maximum run amperage, maxi-
mum 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 break-
er/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
congurations. 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. Oth-
er standard features are: an auxiliary dry alarm contact
for signaling a remote alarm and oat 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 specic 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 with-
out 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

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
minute run time and that the pump goes Off in the
correct position.
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 pro-
ceed 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
oats by lling 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 investi-
gate cause. Operating the pump off the curve, i.e. with
too little head or with high or low voltage will increase
amperage. 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. Three phase unbalance is
also a possible cause. See Three Phase Power Unbalance
and follow the instructions.
Reset the Alarm circuit, place pump switch(es) in the Au-
tomatic position and Control Switch in ON position. The
system is now ready for automatic operation.
Explain the operation of the pumps, controls and alarms
to the end user. Leave the paperwork with the owner or
at the control panel if in a dry, secure location.

THREE PHASE POWER UNBALANCE
A full three phase supply consisting of three individual
transformers or one three phase transformer is recom-
mended. “Open” delta or wye connections using only two
transformers can be used, but are more likely to cause poor
performance, overload tripping or early motor failure due to
current unbalance.
Check the current in each of the three motor leads and cal-
culate the current unbalance as explained below.
If the current unbalance is 2% or less, leave the leads as
connected.
If the current unbalance is more than 2%, current readings
should be checked on each leg using each of the three
possible hook-ups. Roll the motor leads across the starter in
the same direction to prevent motor reversal.
To calculate percent of current unbalance:
A. Add the three line amp values together.
B. Divide the sum by three, yielding average current.
C. Pick the amp value which is furthest from the average
current (either high or low).
D. Determine the difference between this amp value (fur-
thest from average) and the average.
E. Divide the difference by the average. Multiply the result by
100 to determine percent of unbalance.
Current unbalance should not exceed 5% at service factor
load or 10% at rated input load. If the unbalance cannot be
corrected by rolling leads, the source of the unbalance must
be located and corrected. If, on the three possible hookups,
the leg farthest from the average stays on the same pow-
er lead, most of the unbalance is coming from the power
source.
Contact your local power company to resolve the imbalance.
