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 assem-
blies. 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 (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 affix it
to the control panel when finished with the installation.
LIFTING OF PUMP
DO NOT LIFT, CARRY OR HANG

can shock, burn or
cause death.
Lift the pump with an adequately sized chain or cable at-
tached 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, avoid-
ing 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"
4
backwards and may cause premature seal and/or bear-
ing wear. If the pump is turning backwards when it is
called on to start the increased torque may cause dam-
age 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
⁄
" (3.2mm) relief hole. If pumping waste wa-

ter containing solids, drill a
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 re-
lief 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

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,
