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 qualied 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, 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
swimming pools, open bodies of water,
hazardous liquids, or where ammable gases exist. These
uids and gases may be present in containment areas. Tank or
wetwell must be vented per local codes.
Only pumps specically Listed for Class 1, Division 1 are allowable in hazardous liquids and where ammable 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.
All three phase (3Ø) control panels for
submersible pumps must provide
Class 10, quick-trip, overload protection.
PRE-INSTALLATION CHECKS
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 overll, 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, rell 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. 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 (voltage/
phase supply).
Attach the extra label supplied with the pump to this manual
and 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 afx it to
the control panel when nished with the installation.
LIFTING OF PUMP
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/
OPTIONAL GUIDE RAIL/
BASE ELBOW SYSTEM
BASE ELBOW SYSTEM
In many efuent and sewage basins or lift stations it is
advisable to install the pump on a guide rail system 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 should locate the pump opposite the inuent 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.

WARNING
WARNING
WARNING
Hazardous voltage
can shock, burn or
cause death.
PIPING
PIPING
Discharge piping should be no smaller than the pump discharge diameter and kept as short as possible, avoiding unnecessary ttings to minimize friction losses.
Install a check valve to prevent uid backow. Backow
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. 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 sufcient size to allow for
inspection, maintenance and crane or hoist service.
WIRING AND GROUNDING
WIRING AND GROUNDING
Important notice: Read Safety Instructions before proceeding
with any wiring.
PROVIDED WITH THE GUIDE RAIL
ASSEMBLY.
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 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 location.
The junction box must insure dry, safe wiring
connections.
Seal all controls from gases present which
may damage electrical components.

Important – Read Before Proceeding
Single-Phase Motor Design Change Information –
Only for New Pump Installed on Older Panel.
Overload and Capacitors: Single-phase pumps built after
Dec.1, 2005 (M05 date code) now feature a built-in, on
winding overload. If replacing a pre-Dec 2005 pump (date
code L05 or earlier) you have to change the capacitors in the
old style control panel.
Pilot Duty Thermal Sensor/Overload Wire: Pre-Dec 2005
single-phase pumps had a pilot-duty thermal sensor wire
connected between the pump and an overload heater block in
the control panel, you will have to install a jumper wire across
the two high temperature/overload terminals when installing
a new pump on an old panel or the new pump may not operate.
Standard single-phase pumps no longer have a Pilot Duty
Thermal Sensor Wire but it is available as an option. Another
option is a Seal Fail Sensor & Wire. Please use the Nomenclature data found in this manual and the pump Order Number
to determine which optional features are on the pump being
installed.
CONTROL PANEL REQUIREMENTS
Single Phase Control Panels – Eff. Dec. 2005, M05 date code,
Series 1GD and 12GDS single phase grinder pumps require a
control panel containing as a minimum:
• Magnetic contactor
• Start capacitor
• Run capacitor
• Start relay
• Terminal wiring strip for all external connections.
See Recommended Panel Chart in Engineering Data Section

Three Phase Control Panels
Series 1GD and 12GDS three phase grinder pumps require a
control panel containing as a minimum:
• A 3 pole circuit breaker.
• Magnetic starter with ambient compensated Class 10
overloads.
• Transformer to supply 115 or 24 volt control power.
• Terminal wiring strip for all external connections.
RECOMMENDED CONTROL PANEL AND
PUMP OPTIONS
• A panel seal failure circuit with relay and warning device can
only be used if pump is equipped with a seal failure sensor.
• High level alarm circuit
• Visual and/or audible high level alarm device.
Our Simplex and Duplex “Single Phase Grinder Panels” (see
the price book) contain built-in capacitors, a start relay and
wiring terminals.
In the event you wish to source a control panel locally we sell
capacitor kits which a panel shop will be able to build into a
custom panel. Note: the kits contain the capacitors and start
relay. These are not a eld installable, add-on item. Building
the capacitor kits into a control panel is a job for a UL or CSA
approved panel shop. Due to concern for liability, installer
safety and Agency Listing, our Customer Service technicians
are forbidden to assist anyone attempting to eld modify a
standard control panel using these capacitor kits. We hope you
understand and respect our position in this matter. “Recommended Control Panels” are listed in the Product Bulletins
found in the respective product catalog or on the website
named on the front cover of this IOM.
Motor High Temperature Sensor:
The single phase 1GD or 12GDS pumps have an optional
feature, a built-in motor high temperature sensor. This heat
sensor opens and closes the circuit to the contactor coil when
properly wired into a control panel. It opens at a motor temperature of 275°F (135°C) and stops the pump. As the motor
temperature drops to 112°F (78°C) the motor automatically
restarts.
Pump Seal Failure (Moisture Detection) Sensor:
An option on the 1GD and standard on the 12GDS. This
sensor located in the seal chamber detects the presence of
moisture in the seal chamber. When connected to an optional
seal failure relay and warning device in the control panel it
signals that service needs to be performed on the lower seal.
The seal failure circuit option must be ordered as a control
panel option, it is not supplied as a standard item.
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 between 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 applications or to empty a tank. Normally closed (NC) switches are
used to pump up or to ll a tank.
A control switch may be used only with a control panel, never
direct connected to a pump.
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 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
oats 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 oats. 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
qualied 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.

INSTALLATION
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 oor.
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
motors/impellers.

DANGER
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
Hazardous Machinery
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
OPERATION
Once the piping connections are made and checked you can
run the pumps.
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 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 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. 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 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.

THREE PHASE POWER UNBALANCE
THREE PHASE POWER UNBALANCE
A full three phase supply consisting of three individual
transformers or one three phase transformer is recommended. “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
calculate 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
(furthest 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 power lead, most of the unbalance is coming
from the power source.
Contact your local power company to resolve the
imbalance.
