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 electrical work must be performed
by a qualified technician. Always follow
the National Electrical Code (NEC), or the Canadian
Electrical Code, as well as all local, state and provincial
codes. Code questions should be directed to your local
electrical inspector. Failure to follow electrical codes and
OSHA safety standards may result in personal injury or
equipment damage. Failure to follow manufacturer’s
installation instructions may result in electrical shock, fire
hazard, personal injury or death, damaged equipment,
provide unsatisfactory performance, and may void manufacturer’s warranty.
Pumps are not designed for use in swim-
ming pools, open bodies of water, hazardous liquids, or where flammable gases exist. These fluids
and gases may be present in containment areas. Tank or
wetwell must be vented per local codes.
Only pumps specifically Listed for Class 1, Division 1
are allowable in hazardous liquids and where flammable
gases may exist. See specific 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 overheated pump to restart unexpectedly.
IMPORTANT PRE-INSTALLATION
INFORMATION
The pump must be connected to a dedicated electrical circuit protected by a properly sized circuit
breaker or fuses. Install a disconnect where required
by code. Code questions should be directed to your
electrical inspector.
Pumps and floats equipped with a 3-prong grounded plug must be connected to a 3-wire receptacle.
Do not attach to extensions or connectors without
a 3-prong grounded plug. NOTE: Removing the
plug from the power cord is not allowable per NEC
code. Removing the plug will void the agency listing.
CAUTION
WARNING
grounding-type attachment plug. To reduce the risk
of electric shock, be certain that it is connected only
to a properly grounded, grounding-type receptacle.
This pump has been evaluated for use
with water only.
Risk of electric shock – this pump is supplied with a grounding conductor and
GENERAL INFORMATION
Sump pumps are designed to operate intermittently and
usually seasonally. It is recommended that you test the
pump before your rainy season begins to insure that the
pump and switch are operating properly.
We suggest installing a high water alarm system and a
battery back-up pump system for finished basements
or areas where flooding will cause property damage. A
back-up generator is another option you can discuss with
your pump installer. Most power outages occur during
rain storms, just when you need your sump pump the
most! Pump manufacturer’s warranties cover only the
pump. Labor and incidental damage such as flooding is
not covered.
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-filled. 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 overfill, leave room for expansion!
If low, refill with an ASTM 150 turbine oil. Replace the
plug.
Oil is available in 5 gallon cans through our distributors.
You can also 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.

can shock, burn or
cause death.
Check the strain relief nut on power cable strain assemblies. Power cables should be torqued to 75 in. lbs. for
#16 cables and 80 in. lbs. for all other cable assemblies.
Warranty does not cover damage caused by connecting
pumps and controls to an incorrect power source (voltage/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 affix
it to the control panel when finished with the installation.
LIFTING OF PUMP
DO NOT LIFT, CARRY OR HANG
PUMP BY THE ELECTRICAL
CABLES. DAMAGE TO THE
ELECTRICAL CABLES CAN CAUSE
SHOCK, BURNS OR DEATH.
Lift the pump with an adequately sized chain or cable attached to the lifting eye bolt. DO NOT damage electrical
and sensor cables while raising and lowering unit.
OPTIONAL GUIDE RAIL
OR LIFT-OUT SYSTEM
In many effluent 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 protective
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
influent 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 floor must
be flat.
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, avoiding
unnecessary fittings to minimize friction losses.
Install an adequately sized check valve matched to the
solids handling capability of the pump to prevent fluid
backflow. Backflow can allow the pump to “turbine” backwards and may cause premature seal and/or bearing 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 and some single-phase pumps
may actually run backwards.
Install an adequately sized gate valve AFTER the check
valve for pump, plumbing and check valve maintenance.
Important – Before pump installation. If pumping water,
drill a 1⁄8” (3.2mm) relief hole. If pumping waste water
containing solids, 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
4
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 sufficient 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
coded 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 fire, 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 location. 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

SELECTING AND WIRING
PUMP CONTROL PANELS AND SWITCHES
FLOAT SWITCH TYPES
There are three types of float switches typically used
on single phase pumps; single action, vertical and wide
angle.
Single action control switches can only be connected
through a control panel. Connecting them directly to a
pump will cause rapid cycling and may burn up the motor, and/or the motor start switch and/or the float switch.
If using single action switches with a control panel please
see the Float Switch and Panel Section.
Vertical mechanical float switches with piggyback plugs
are available for single phase pumps. They are an ideal
choice where there is limited space for a switch. They
require less room than a wide angle switch because they
travel in a vertical direction. Typical model numbers start
with A2H…
WARNING
Hazardous voltage
can shock, burn or
cause death.
Wide angle float switches are the most popular type.
They can be directly connected to a pump or to a control panel. The “tether length” or the distance from the
switch body to the pivot point controls the On and Off
points and the amount pumped in one cycle. The pivot
point is where the float is attached either to the pump or
the discharge pipe. See Figures 1 - 5.
SETTING THE FLOAT SWITCHES
There are no absolute rules for where to set the float
switches, it varies from job to job.
Suggested Rules to Follow:
All floats should be set below the Inlet pipe!
Off Float: Best: set so 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 floats allows pumps of 1½ HP and under to operate
for 1 minute minimum. Two (2) HP and larger pumps
should run a minimum of 2 minutes. Basin literature
states the gallons of storage per inch of basin height.
Lag/Alarm Float(s): should be staggered above the Off
and On floats. Try to use most of the available storage
provided by the basin, save some space for reserve storage capacity. 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 qualified technicians. Any problem or questions
pertaining to another brand control must be referred
to that control supplier or manufacturer. Our technical
people have no technical schematics or trouble shooting
information for other companies’ controls.
ALARMS
We recommend the installation of an alarm on all Wastewater pump installations. Many standard control panels
come equipped with alarm circuits. If a control panel is
not used, a stand alone high liquid level alarm is available. The alarm alerts the owner of a high liquid level in
the system 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 hard wired float switch, a contactor, or a Simplex
or Duplex control panel. See Figures 1, 2 and 5.
All 1/3 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 waste water pumps contain on-winding overloads, unless noted on the pump nameplate. See
Figures 1 and 2.
SINGLE PHASE CONTROL PANELS:
Control panels are available as Simplex (controls 1
pump) or Duplex (controls 2 pumps). Our standard
control 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 standard 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 standard 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. Most standard panels are in stock
for immediate delivery.
INSTALLATION IN SUMP WITHOUT
SLIDE RAILS
Is your basin sized correctly and the proper type for the
location?
Diameter - It must be wide enough to allow the pump
and switch to physically fit and provide room for the
switch to operate freely. The vertical switch models
typically require less diameter than the wide-angle
float models. See “min. basin diameter” in Chart 1.
CAUTION
turns the pump On. As an example, if the pump turns
on at 15” you want to use a basin deeper than 15”.
See “On level” in Chart 1.
WARNING
sump determines if you require a cover and what type
you require. It is important to keep debris from entering the sump and clogging the pump. An open sump
in a traffic area such as a basement is dangerous. If
children or pets will be playing in the area a bolt-on or
child-proof cover is recommended.
The pump can be placed directly on the bottom of a poly
or fiberglass sump basin or a concrete sump bottom. If
the bottom is packed gravel the stones must be larger
than ½” (13mm) in diameter and the pump should be
placed on bricks for support.
After connecting the discharge pipe to the pump it can be
lowered into the sump (basin). Always lower the pump by
the handle and the pipe, never by the power cord. Place
the pump against the basin wall so the switch is to the
center. See “Installation Data”.
Check to insure all piping connections are tight. The
pipes should be supported by fastening to floor joists or
wall. This will prevent the pump from moving in the
sump. If it moves the switch could get stuck and either
keep the pump running or not let it turn on.
Depth - It must be deeper than the
minimum depth at which the switch

The power to the outlet should be Off at this point. The
dedicated outlet should supply power only to the pump.
Our sump pumps have either a single power cord for
pumps with built-in switches or two power cords for
pumps with piggyback switches:
Built-In/Single Cord - plug the single power cord into
a dedicated power outlet.
Piggyback/Two Power Cords - insert the piggyback
switch male plug into a dedicated power outlet. You
then plug the standard male pump plug into the back,
female side, of the piggyback switch plug.
Fasten the power cords to the discharge pipes using tie
wraps or electrical tape. Coil and store any excess power
cord outside the sump.
INSTALLATION
STANDARD PUMP INSTALLATION
Connect the pump(s) to the guide rail pump adapters
or to the discharge piping. Guide 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.

Packaged Sewage Systems – Inspect unit for damage.
Return damaged units to the distributor. Install on solid,
level ground. Remove all tape from discharge pipe, vent
hole, float switch and inlet. Check to insure that the float
swings freely and is attached to the pump. Install the
grommet in the inlet hole and lubricate it before installing the inlet pipe. Connect the vent per code. If installing
outdoors protect the unit from freezing. Install a union
and check valve per valve manufacturer’s instructions.
Install a gate valve on the discharge side of the check
valve for plumbing maintenance. See Typical Installation

INJURY.
Lower the pump(s) into the wetwell.
Check to insure that the floats will
operate freely and will 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 minute run time and that the pump goes Off in the correct
position. Note: Small package systems will normally have
a fast ON-OFF cycle.
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
proceed 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
floats by filling 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 investigate
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.
Reset the Alarm circuit, place pump switch(es) in the
Automatic 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.
