signal words and be alert to the potential
for personal injury or property damage.
Warns of hazards that WILL cause serious
personal injury, death or major property
damage.
Warns of hazards that CAN cause serious
personal injury, death or major property
damage.
Warns of hazards that CAN cause personal
injury or property damage.
NOTICE: INDICATES SPECIAL INSTRUCTIONS WHICH
ARE VERY IMPORTANT AND MUST BE
may exist. See specic pump catalog bulletins or pump

THOROUGHLY REVIEW ALL INSTRUCTIONS AND
WARNINGS PRIOR TO PERFORMING ANY WORK
ON THIS PUMP.
MAINTAIN ALL SAFETY DECALS.
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. For more information go to:
www.P65Warnings.ca.gov.
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.
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.
This pump is 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!
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
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., cable supplied
is for high temp use.
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 afx it to
the control panel when nished with the installation.
FOR ALL SES PUMP INSTALLATIONS
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
cables while raising and lowering unit.
OPTIONAL GUIDE RAIL
OR LIFT-OUT SYSTEM
In many efuent 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 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.
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 ttings to minimize friction losses. Piping should
be rated for high temperatures if used in high temperature
applications.
Install an adequately sized check valve matched to the solids
handling capability of the pump 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.
4
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
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 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.
