Installation 4

Risk of electric shock. Can shock, burn
or kill. Do not lift pump by the power cord. See Cord
LiftWarning.

NOTICE Install the pump on a hard, level surface
(cement, asphalt, etc.). Never place the pump directly on
earth, clay or gravel surfaces.

Piping

Piping must not be smaller than pump discharge.
When installed in a sewage system, the pipe must be

capable of handling semi-solids of at least 2” (51mm)
indiameter.

When installed in an effluent system, the pipe must be
capable of handling semi-solids of at least 3/4” (19mm)
in diameter.

The rate of flow in the discharge pipe must keep any
solids present in suspension in the fluid. To meet
minimum flow requirements (2 feet per second in the
discharge line), size the pipe as follows:

A Pipe Size Of: Will Handle a Flow Rate Of:

1-1/2” (38mm) 12 GPM

2” (51mm) 21 GPM

2-1/2” (64mm) 30 GPM

3” (76mm) 48 GPM

In a sewage system use a 2” (51mm) check valve (not
included) in pump discharge to prevent backflow of
liquid into sump basin. The check valve should be a
free flow valve that will easily pass solids. Be sure check
valve installation complies with local codes.

In an effluent system use a 1-1/2” (38mm) check valve
(not included) in pump discharge to prevent backflow
of liquid into sump basin. The check valve should be a
free flow valve that will easily pass solids. Be sure check
valve installation complies with local codes.

NOTICE For best performance of check valve when
handling solids, do not install it with the discharge more
than 45° above the horizontal. Do not install the check

valve in a vertical position as solids may settle in the
valve and prevent it from opening on startup.

Drill a 3/16” (5mm) hole in the discharge pipe about
1–2” (25-51mm) above the pump discharge connection
(but below check valve) to prevent airlocking the pump.

Electrical

Risk of electric shock. Can shock, burn or
kill. When installing, operating, or servicing this pump,
follow the safety instructions listed below.

1. DO NOT splice the electrical power cord.

2. DO NOT allow the electrical cord plug to

besubmerged.

3. DO NOT use extension cords. They are a fire hazard

and can reduce voltage sufficiently to prevent
pumping and/or damage motor.

4. DO NOT handle or service the pump while it is

connected to the power supply.

5. DO NOT remove the grounding prong from the

plug or modify the plug. To protect against electrical
shock, the power cord is a three-wire conductor and
includes a 3-prong grounded plug. Plug the pump
into a 3-wire, grounded, grounding-type receptacle.
Connect the pump according to the NEC or CEC and
local codes.

For automatic operation, plug or wire the pump into an
automatic float switch or duplex controller. The pump
will run continuously when plugged directly into an
electrical outlet.

Connect or wire pump to its own individual branch
circuit with no other outlets or equipment in the circuit.
Size fuses or circuit breakers according to Motor, Switch
and Cord Specifications.

Risk of electric shock. Can shock, burn or
kill. Be sure that power supply information (Voltage/
Hertz/Phase) on pump motor nameplate matches
incoming power supply exactly. Install pump according
to all electrical codes that apply.

WARNING

Risk of electrical shock.

Can burn or kill.
Do not lift pump by

power cord.

Cord Lift Warning

1. Attempting to lift or support pump by power
cord can damage cord and cord connections.

2. Cord may pull apart, exposing bare wires
with possibility of fire or electrical shock.

3. Lifting or supporting pump by power cord
will void warranty.

4. Use lifting ring or handle on top of pump
for all lifting/lowering of pump. Disconnect
power to pump before doing any work
on pump or attempting to remove pump
fromsump.

Operation • Maintenance 5

Operation

Risk of fire and explosion. Can cause
severe injury, property damage or death. Do not use in
explosive atmospheres. Pump water only with this pump.

NOTICE Do not allow the pump to run in a dry sump. It
will void the warranty and may damage the pump.

An automatic overload protector in the motor will
protect the motor from burning out due to overheating/
overloading. When the motor cools down, the overload
protector will automatically reset and start the motor.

If the overload trips frequently, check for the cause.
It could be a stuck impeller, wrong/low voltage, or
an electrical failure in the motor. If an electrical
failure in the motor is suspected, have it serviced by a
competentrepairman.

The pump is permanently lubricated. No oiling or
greasing is required.

Maintenance

General

Risk of electric shock. Can shock, burn
or kill. Before removing the pump from the basin for
service, always disconnect electrical power to the pump
and the control switch. Do not lift the pump by the
power cord. See Cord Lift Warning.

After removing the basin cover and the necessary
discharge piping, lift the pump out of the basin.

Place the pump in an area where it can be cleaned
thoroughly. Remove all scale and deposits on the pump.

Submerge the complete pump in a disinfectant solution
(dilute chlorine bleach) for at least one hour before
disassembling the pump.

The pump motor housing contains a special lubricating
oil which should be kept clean and free of water at
alltimes.

NOTICE Whenever the motor housing is being removed
for service, remove oil and replace it with new oil at
reassembly. Use only oil listed in parts list in this manual.
When filling with new oil, DO NOT overfill. Allow about
7/8” (22mm) air space from top of boss in housing for
expansion of oil when the pump is operating.

11. Fill with fill with clean SAE 5W-15W (ISO 22-44)
mineral oil, check the oil level and replace the oil fill
plug.

Troubleshooting 7

Risk of electrical shock, cuts, and possible unexpected starts. If the power is on to the pump when
thermal overload resets, the pump may start without warning. If you are working on the pump, you may get an
electrical shock or the impeller may catch fingers or tools. Disconnect the power before servicing the pump.

Symptom Possible Cause(s) / Corrective Action

1. Check to be sure that power cord is securely plugged into outlet or securely wired into controller or switch box. Disconnect
power to outlet before handling pump or motor.

2. Check to be sure you have electrical power.

3. Check that liquid fluid level is high enough to activate switch or controller.

Pump fails to operate.

Pump fails to empty sump.

Pump will not shut off.

4. Check to be sure that 3/16” (5mm) vent hole in discharge pipe is not plugged.

5. Check for blockage in pump inlet, impeller, check valve or discharge pipe.

6. Disconnect the pump from the power source for a minimum of 30 minutes to allow the motor to cool and to protect yourself
from sudden starts. See Warning above. Check for the cause of overheating. Pump is running dry because the float switch is
caught up on something. Inlet pipe is plugged. Outlet pipe is plugged.

1. Be sure all valves in discharge pipe are fully open.

2. Clean out discharge pipe and check valve.

3. Check for blockage in pump inlet or impeller.

4. Pump not sized properly. A higher capacity pump may be required.
