Operating Instructions and Parts Manual

General Information

Sewage Pump Systems:
Simplex System

A simplex system consists of one pump,
its control switch, and one basin. It is
used in applications where less than
six toilets (units) are discharged into
a basin. The simplex unit is generally
operated with a contactor to turn
the pump ON and OFF. The contactor
is activated by a single pole float
switch. The float switch is a wide-angle
differential switch that rises with the
liquid level and turns the pump ON.
As the liquid level decreases, the float
lowers and turns the pump OFF. The
switch differential is 120º.

Sewage Pump Systems:
Duplex System

A duplex system is used in applications
where more than six toilets (units) are
discharged into a basin. However, each
pump should be sized to handle the entire
flow in case one pump fails. The duplex
unit is controlled by a NEMA 1 control
panel that has an automatic alternator,
run lights, hand-off-auto switches, and
an alarm bell. The duplex control panel
is supplied with three float switches. The
floats are to be positioned so that the
lower float turns the pumps OFF. The
second float alternates turning first one
pump ON and then the other pump ON.
The third float will turn BOTH pumps ON
in case one pump cannot handle the flow.
The third float will also sound the alarm
(which remains on until the system is reset).

Functionally, the liquid in the basin rises
and trips the first float, but the pumps do
not turn ON. As the liquid level rises, it
trips the second float, activating one of the
pumps. Once the liquid level recedes and
no longer trips the second float, the pump
will turn OFF. If the second float is tripped
again, the other pump will turn ON.

If for some reason the liquid level
increases past the second float and trips
the third float, both pumps turn ON and
trips the alarm.

Under normal circumstances, the first
pump will handle the flow after the
second float is tripped. In those cases,
the liquid level will recede until it drops
the lower float. This action turns the
pump OFF. The next time that the liquid
level rises, the other pump turns ON. This
alternates the pumps; this prevents lock­up and extends the lifer of both pumps.

Available Controls

For 115 volt only, a wide angle float
switch can be supplied with a plug-thru
series plug.

For 230 volt Simplex units, a NEMA 1
Simplex Controller with a hand-off-auto
switch and run light can be supplied.
This is supplied with a wide-angle
switch for automatic operation.

For 230 volt Duplex units, a NEMA 1
control panel can be supplied with
a hand-off-auto switches, run lights,
pump alternator, and an alarm bell.
This is supplied with a three float switch
system for automatic operation.

Installation

Always

disconnect
the power source before
attempting to install, service,
relocate or maintain the pump.
Never touch sump 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.

Some models of this product include
a grounded plug for quick installation
anywhere a grounded outlet is
accessible. Some models must be
incorporated into the building’s
electrical system. Models without plugs
must be connected to a grounded
circuit. The circuit should be equipped
with a ground fault interrupter device.

All models without plug-in power cords
systems must be installed by a qualified
electrician. All models with a plug-in
power cords system should still have a
qualified electrician inspect the outlet
being used to ensure proper wiring.

The control switch is a wide-angle
system which prevents short cycling of
the pump motor and the consequential
problems that short cycling can cause.
The switch can be mounted on the
discharge pipe (just above the pump
discharge flange). See illustrations for
switch mounting arrangements.

Operating Instructions and Parts Manual

Installation (Continued)

INSTALLATION BASICS:

1. NEVER lift this product by the
electrical cords.

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.

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.

Flood risk. If

fl exible discharge
hose is used, make sure pump is secured
in sewage pit to prevent movement.
Failure to secure pump could allow pump
movement and switch interference and
prevent pump from starting or stopping.

4. Thread the discharge pipe or pipe

nipple into the discharge flange
connection.

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.

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).

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.

8. Connect 2 in. rigid pipe to check
valve.

Support pump

and piping when
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.

9. Protect electrical cord from sharp

objects, hot surfaces, oil and
chemicals. Avoid kinking the cord and
replace damaged cords immediately.

IMPORTANT: Make sure there is
adequate room for tether switch to
swing freely during operation.

10. A pit cover must be installed to

prevent debris from clogging or
damaging the pump. All piping and

power cords will be brought through
the appropriate openings in the
basin cover. Do not modify existing
openings in any way.

All sewage basins

must be vented
to prevent a build-up of methane gas.
Consult your local codes for proper
venting. DO NOT install venting in
locations classifi ed as hazardous in
accordance with the National Electrical
Code NFPA 70.

Operation

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.

1. Verify pump and switch operate

within the basin.

Risk of electrical

shock! This pump
is supplied with a grounding conductor
and grounding type attachment plug.
Use a grounded receptacle to reduce the
risk of fatal electrical shock.

Never cut off the round grounding
prong. Cutting the cord or plug will
void the warranty and make the pump
inoperable.
