Installation • Operation
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 (.6 m) per second in
discharge line), size pipe as follows:
Pipe Size (In/cm)
2 (5.1)
2-1/2 (6.3)
3 (7.6)
The pump must always be lifted by the lift-out chain or
cable and never by the power supply cable. See Cord
Lift Warning.
4. To reduce motor noise and vibrations, a short length
of rubber hose, e.g. radiator hose, can be connected
into discharge line near pump using suitable clamps.
5. If the pump discharge line is exposed to outside
subfreezing atmosphere, then the portion of line
exposed must be installed so any water remaining in
pipe will drain to outfall by gravity. Failure to do this
can cause water trapped in discharge to freeze which
could result in damage to pump.
6. Install a 2" check valve in the horizontal portion of
the discharge pipe. Make certain, the flow indicating
arrow, points away from the pump. This check valve
will keep the water from either running back into the
basin or into the area being pumped out when the
pump is not running. Check valve should be a free
flow valve that will easily pass solids.
NOTICE For best performance of check valve when
handling solids, do not install it with discharge
angled more than 45° above the horizontal. Do not
install check valve in a vertical position as solids
may settle in valve and prevent opening on startup.
7. Drill a 3/16" (4.7mm) hole in discharge pipe
about 1"-2" (2.5 - 5.1cm) above pump discharge
connection (but below check valve) to prevent the
pump from airlocking.
8. Insert the float switch piggy-back plug into a properly
grounded outlet and the pump plug into the piggy-
back plug.
9. Check the installation by observing the pump
operation through one complete cycle. Make sure
that no parts of the assembly interfere with the
float switch.
Risk of flooding. Can cause personal injury
and/or property damage. Failure to make this operational
check may lead to improper operation, premature failure,
and flooding.

Electrical
Risk of electric shock. Can shock, burn or
kill. When installing, operating, or servicing this pump,
follow safety instructions listed below.
1. DO NOT splice the electrical power cord.
2. DO NOT allow 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 lift unit by cord.
5. DO NOT handle or service pump while it is
connected to power supply.
6. DO NOT remove grounding prong from plug or
modify plug. To protect against electrical shock, the
power cord is a three-wire conductor and includes
a 3-prong grounded plug. Plug pump into a 3-wire,
grounded, grounding-type receptacle. Connect pump
according to electrical codes that apply.
For automatic operation, plug or wire pump into an
automatic float switch or pump controller. Pump will run
continuously when plugged directly into an electrical
outlet. Connect pump to its own individual branch circuit
with no other outlets or equipment in the circuit. Size
fuses or circuit breakers according to Specifications chart.
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.
Operation
NOTICE Do not allow 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 motor from burning out due to overheating/
overloading. When motor cools down, overload
protector will automatically reset and start motor.
If overload trips frequently, check for cause. It could
be a stuck impeller, wrong/low voltage, or electrical
failure in motor. If an electrical failure in the motor is
suspected, have it serviced by a competent repairman.
Pump is permanently lubricated. No oiling or greasing
is required.
