General Information / Installation 3
14. Protect the electrical cord from sharp objects, hot surfaces,
oils, and chemicals. Avoid kinking the cord. Replace or
repair damaged or worn cords immediately.
15. Do not touch an operating motor. Motors can operate at
high temperatures.
16. Do not handle the pump or pump motor with wet hands or
when standing on a wet or damp surface, or in water.
Risk of electric shock. Can burn or kill. If your
basement has water or moisture on floor, do not walk on the
wet area until all power has been turned off. If the shut-off box
is in the basement, call electric company or hydro authority to
shut-off the service to house, or call your local fire department
for instructions. Failure to follow this warning can result in fatal
electrical shock.
17. DO NOT splice the electrical power cord.
18. DO NOT allow the electrical cord plug to be submerged.
19. DO NOT use extension cords. They are a fire hazard and
can reduce voltage sufficiently to prevent pumping and/or
damage motor.
20. Connect or wire the pump to an individual branch circuit
with no other outlets or equipment in the circuit. Size fuses
or circuit breakers according to the specifications.
DESCRIPTION
This submersible sump pump is designed for use in home
sumps. The unit is equipped with a 3-prong grounding-type
power cord. The shaded-pole motor is oil filled and sealed for
cooler running. The sleeve bearings on the motor shaft never
needs lubrication. The pump includes automatic reset thermal
protection.
SPECIFICATIONS

water or brine! Use with salt water or brine will void warranty.
PERFORMANCE
INSTALLATION
1. Install in a sump pit with a minimum diameter of 11"
(279mm). Construct the sump pit of tile, concrete, steel or
plastic. Check the local codes for approved materials.
The pump should not be installed on clay, earth or sand sur-
faces. Clean the sump pit of small stones and gravel which
could clog the pump. Keep the pump suction housing clear
of debris.
2. Install the pump in the pit so the switch operating mecha-
nism has maximum possible clearance.
3. Install an in-line check valve to prevent flow backwards
through the pump when the pump shuts off.
4. Install the discharge plumbing.
A. When using rigid pipe, use plastic pipe. Wrap the dis-
charge pipe thread with Teflon TM tape. Screw the pipe
into the pump discharge port hand tight +1 – 1-1/2 turns.
NOTICE: Do not use ordinary pipe joint compound on
plastic pipe. Pipe joint compound can attack plastics.
NOTICE: Thread the discharge pipe into the pump body
carefully to avoid stripping or crossing threads.
B. If a flexible discharge hose is used, make sure the pump
is secured in the sump to prevent movement. Do not use
a flexible discharge pipe in any permanent installation.
Risk of flooding. Can cause personal
injury or property damage. Failure to secure pump may
allow pump movement, switch interference and prevent
pump from starting or stopping.
NOTICE: The discharge piping should be as short as pos-
sible to reduce pipe friction losses. Discharge pipe diam-
eter should be equal to or larger than the discharge size
of the pump. Smaller pipe diameters will restrict the
capacity of the pump and reduce pump performance.
C. Secure the discharge line before starting the pump.
To reduce motor noise and vibrations, a short length of
rubber hose (e.g. radiator hose) can be connected into
the discharge line near the pump using suitable clamps.
If the pump discharge line is exposed to outside sub-
freezing atmosphere, the portion of the line exposed
must be installed so any water remaining in the pipe will
drain to the outfall by gravity. Failure to do this can
cause any water trapped in the discharge line to freeze
which could result in damage to pump.
