DESCRIPTION
This Submersible Sump Pump has a thermoplastic body and
base and 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 need lubrication.
The pump includes automatic reset thermal protection.

INSTALLATION
1. Install the pump in a sump pit with a minimum diameter
of 12" (305mm). Construct the sump pit of tile, con-
crete, 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 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.
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
discharge size of the pump. Smaller pipe diameters
will restrict the capacity of the pump and reduce
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

at height
shown
below If the pump discharge line is exposed to outside sub-
24 Ft. freezing atmosphere, the portion of the line exposed
(7.3m)
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.
NOTICE: Drill a 1/8" (3.2 mm) hole in discharge pipe
just above pump body but below the check valve to
prevent air locks.
5. Power Supply: The 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.

and grounding-type attachment plug. To reduce the risk of
electric shock, be certain that it is connected only to a
properly grounded, grounding type receptacle such as a
grounded water pipe or a properly grounded metallic race-
way or ground wire system. Ground terminal on pump cord
plug is provided for your protection. DO NOT REMOVE!
