Warns of hazards that CAN cause personal injury or property damage.
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.
Standard units are not designed for use in
swimming 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.
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.
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.

WARNING
Hazardous
voltage
WARNING
WARNING
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 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 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 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
TO POWER CAN CAUSE SHOCK,

SELECTING AND WIRING
PUMP CONTROL PANELS AND SWITCHES
FLOAT SWITCH TYPES
There are two types of float switches available for use
with 2 HP, single phase grinder pumps; single action control switches and wide angle mechanical switches.
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.
Model A2G33 wide angle pump float switches can be
hard wired directly to the pump. Wide angle switches can
operate the pump via connection to a control panel. The
tether length or 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 to the discharge pipe. See Figures 1 and 2.
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 two (2) HP and larger pumps to 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.

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
Figure 1.
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
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.
!
DANGER
Hazardous Machinery
Connect the piping per local codes and the drawings in
Typical Drawings Section.
DO NOT PLACE HANDS IN PUMP
SUCTION WHILE CHECKING
MOTOR ROTATION. TO DO SO
WILL CAUSE SEVERE PERSONAL
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.
Hard Wired Float Switch Operation – Turn circuit breaker or fused disconnect to On. 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 two 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
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.
