Electrical / Operation

Piping – Effluent Applications
(3/4" or Less Solids)
Piping must be 1-1/2" minimum to carry volume of
pump discharge. Check local codes to determine if a
check valve is required in your system. In cold climates,
check valves are not used to prevent effluent from
freezing in piping.
Piping – Sewage Applications
(2" or Less Solids)
In any case, piping must not be smaller than pump
discharge.
When installed in a sewage system, pipe must be capable
of handling semi-solids of at least 2" (5.1 cm) 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 (.6 m) per second in
discharge line), size pipe as follows:
Pipe Size (In/cm)
1-1/2 (3.8)
2 (5.1)
2-1/2 (6.3)
3 (7.6)
NOTICE: Use Teflon™ tape on pipe connections. Do not
use ordinary pipe joint compound on plastic pipe or
pump. Pipe joint compound can attack plastics and
damage pump.
3. To reduce motor noise and vibrations, a short length
of rubber hose (1-5/8"(41mm) I.D., e.g. radiator hose)
can be connected into discharge line near pump
using suitable clamps.
4. 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.
5. 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.
6. 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
airlocking the pump.
7. Insert the float switch piggy-back plug into a
properly grounded outlet and the pump plug into the
piggy-back plug.
8. 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. May cause personal injury
or property damage. Failure to make this operational
check may lead to improper operation, premature failure,
and flooding.
Electrical
Hazardous voltage. Can shock, burn, or
cause death. 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 handle or service pump while it is
connected to power supply.
5. 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 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 chart on Page 2.
Risk of electrical shock and fire. Can burn or
cause death. 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.
