DESCRIPTION
This Submersible Sump Pump is designed for 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 run-
ning. Sleeve bearing on the motor shaft never needs lubrica-
tion. Automatic reset thermal protection.
NOTICE: This unit is not designed for applications involving
salt water or brine! Use with salt water or brine will void
warranty.
Pump water only with this pump.

INSTALLATION
1. Install the pump in a sump pit with a minimum diameter
of 10" (254mm). The sump depth should be 14" mini-
mum)(356mm). Construct the sump pit of tile, concrete,
steel or plastic. Check local codes for approved materials.
2. Install the pump in the pit so the switch operating mecha-
nism has maximum possible clearance.
3. 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 inlet screen
clear.
NOTICE: Do not use ordinary pipe joint compound on plas-
tic pipe. Pipe joint compound can attack plastics.
4. Install discharge plumbing. When using rigid pipe, use
plastic pipe. Wrap the thread with Teflon
pipe into the the pump hand tight plus
1 – 1-1/2 turns.

Risk of flooding. Can cause personal injury
or property damage. If a flexible discharge hose is used,
make sure the pump is secured in the sump to prevent move-
ment. Failure to secure the pump may allow pump movement,
switch interfere e and prevent the pump from starting or
stopping.
5. To reduce motor noise and vibrations, a short length of
rubber hose (1-7/8" (47.6mm) ID, e.g. radiator hose) can
be connected into the discharge line near the pump using
clamps.
6. Install an inline check valve to prevent backward flow
through the pump when the pump shuts off.
7. Power Supply: The pump is designed for 115V, 60 Hz.,
operation and requires a 15 amp individual branch circuit.
Both the pump and the switch are supplied with a 3-wire
cord with grounding-type plug. The switch plug is inserted
directly into the outlet and the pump plug inserts into the
opposite end of the switch plug.
Hazardous Voltage. Can shock, burn or
cause death. The pump should always be electrically
grounded to a suitable electrical ground such as a ground-
ed water pipe or a properly grounded metallic raceway, or
ground wire system. Do not cut off the ground pin.
8. If the discharge line is exposed to outside sub-freezing
temperatures, that portion of the line must be installed so
any water remaining the pipe will drain to the outfall by
gravity. Failure to do this can cause the water trapped in
the discharge line to freeze which could result in damage
to the pump.
9. After the piping and the check valve have been installed,
the unit is ready for operation.
10. Check the operation by filling the sump with water and
observing the pump operation through one complete cycle.
Flood hazard. Can cause personal injury
or property damage. Check the operation of the pump by
observing through one complete cycle. Failure to make this
operational check may lead to improper operation, prema-
ture failure, and flooding.
