Operating Instructions and Parts Manual
6. Drill a 1/8 in. hole in the discharge
pipe 1 to 2 inches above the flange.
This will prevent air locking and loss
of prime at startup. A gate valve
should be installed in the system
after the check valve. This gate valve
should be a full port valve which
will pass 2 in. solids or as required by
state and local codes. The gate valve
permits removal of the pump and/
or the check valve for servicing (and
will minimize back-flow mess).
power cords will be brought through
the appropriate openings in the
basin cover. Do not modify existing
openings in any way.
Installation (Continued)
INSTALLATION BASICS:
1. NEVER lift this product by the
electrical cords.
All sewage basins
must be vented
2. Install pump in a sewage pit
that fulfills the minimum size
requirements (24 in. minimum).
Construct sump pit of tile, concrete,
steel or plastic. Do not install a pit
smaller than recommended.
to prevent a build-up of methane gas.
Consult your local codes for proper
venting. DO NOT install venting in
locations classified as hazardous in
accordance with the National Electrical
Code NFPA 70.
3. The unit should be located and
rest on a solid, level foundation.
Do not place pump directly on clay,
earth, gravel or sandy surface. These
surfaces contain small stones, gravel,
sand, etc. that may clog or damage
the pump and cause pump failure.
Operation
7. (OPTIONAL) Install a union between
the check valve and the pump so the
pump can be removed with the least
amount of disturbance of the piping.
Always
disconnect
the power source before
attempting to install, service,
relocate or maintain the
pump. Never touch sewage pump, pump
motor, water or discharge piping when
pump is connected to electrical power.
Never handle a pump or pump motor
with wet hands or when standing on
wet or damp surface or in water. Fatal
electrical shock could occur.
8. Connect 2 in. rigid pipe to check
valve.

assembling and after installation.
Failure to do so could cause piping to
break, pump to fail, etc. which could
result in property damage and/or
personal injury.
1. Verify pump and switch operate
within the basin.
4. Thread the discharge pipe or pipe
nipple into the discharge flange
connection.
9. Protect electrical cord from sharp
objects, hot surfaces, oil and

shock! This pump
is supplied with a grounding conductor
and grounding type attachment plug.

risk of fatal electrical shock.
chemicals. Avoid kinking the cord and
replace damaged cords immediately.
5. A check valve MUST be used in a
solids-handling system. Mount the
check valve in a horizontal position
or at a 45º angle with the valve pivot
on top. In a vertical position, solids
tend to lodge on the valve flapper
and can prevent it from opening.
IMPORTANT: Make sure there is
adequate room for tether switch to
swing freely during operation.
Never cut off the round grounding
prong. Cutting the cord or plug will
void the warranty and make the pump
inoperable.
10.A pit cover must be installed to
prevent debris from clogging or
damaging the pump. All piping and

2. Disassembly of the motor prior to
expiration of warranty will void the
warranty. If repairs are required, see
troubleshooting chart.
Operation(Continued)
2. With the cover removed, add water
to the basin and observe the float
control switch operation.
Maintenance
Always disconnect
the electrical
supply before attempting to install,
service, relocate or perform any
maintenance. If the power source is out
of sight, lock and tag in the open (off)
position to prevent unexpected power
application. Failure to do so could result
in fatal electrical shock. Only qualified
electricians should repair this unit.
Improper repair could result in fatal
electrical shock.
3. Inlet should be kept clean and free
of all foreign objects and inspect
annually. A clogged inlet will
damage pump.
3. Also, test alarm switch if installed.
4. Secure and seal basin cover.
4. Pump should be checked monthly
for proper operation.
Do not run your pump in a dry sump.
This pump contains
dielectric oil for
cooling. This oil can be harmful to
the environment. Check the state
environmental laws before disposing
this oil.
Do not attempt to
oil the motor. A
special oil has been put in the motor
housing at the factory. Use of any other
oil could damage the pump and WILL
void the warranty.
1. Let the pump cool for a minimum of
two hours before servicing because
the pump contains hot oil under
pressure and the motor is hot.

Symptom
Possible Cause(s)
Corrective Action
Pump will not start or run
1. Blown fuse, tripped breaker
2. Low line voltage
1. If blown, replace with proper sized fuse or reset breaker
2. If voltage is under 108 volts, check wiring size
3. Replace pump
3. Defective motor
4. Defective float switch
5. Stuck/ jammed impeller
4. Replace float switch
5. If impeller will not turn, remove housing and remove
blockage
6. Float obstructed
6. Make sure float(s) move freely up and down
1. Install or replace check valve
Pump starts and stops too
often
1. Back-flow of water from
piping
2. Replace float switch
2. Faulty float switch
Pump will not shut off or

1. Defective float switch
2. Obstacle in piping
3. Float obstructed
4. Low line voltage
1. Replace float switch
2. Remove pump and clean pump and piping
3. Make sure float move freely up and down
4. If voltage is under 108 volts, check wiring size
5. Too many appliances on
circuit
5. Install pump on dedicated circuit. IMPORTANT: Do not
use extension cord to power pump.
Pump operates but delivers
little or no water
1. Plugged impeller
1. Clean out impeller
2. Check valve installed
backwards
2. Reverse position of check valve
3. Pump air locked
3. Check the 1/8 in. hole in discharge line between
pump and check valve; it should be 1 in. to 2 in. above
discharge flange and before the check valve
