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.

Discharge Port ..................................................1-1/4" FNPT
NOTICE: This unit is not designed for applications involving
salt water or brine! Use with salt water or brine will void
warranty.
INSTALLATION
1. Install in a sump pit with a minimum diameter of 14"
(356mm). 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
surfaces. Clean the sump pit of small stones and gravel
which could clog the pump. Keep the pump suction hous-
ing 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
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.
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
possible to reduce pipe friction losses. Discharge pipe
diameter should be equal to or larger than the dis-
charge 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.
5. Power Supply: This pump is designed for 115 V., 60 Hz.,
operation and requires a minimum 15 amp individual
branch circuit. Both the pump and switch are supplied
with 3-wire cord sets with grounding-type plugs. The
switch plug is inserted directly into the outlet and the
pump plug inserts into the opposite end of switch plug.
