To reduce risk of electric shock, pull
plug before servicing. This pump has not been inves-
tigated for use in swimming pool areas. Pump is sup-
plied with a grounding conductor and grounding-type
attachment plug. Be sure it is connected only to a
properly grounded grounding-type receptacle.
Where a 2-prong wall receptacle is encountered, it
must be replaced with a properly grounded 3-prong
receptacle installed in accordance with codes and
ordinances that apply.
12. A ground fault circuit is recommended for use with any
electrical appliance submerged in water. Installation and
all wiring should be performed by a qualified electrician.
13. Make certain power source conforms to requirements of
your equipment.
14. Protect electrical cord from sharp objects, hot surfaces,
oil, and chemicals. Avoid kinking 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 pump or pump motor with wet hands or
when standing on wet or damp surface, or in water.
Risk of electric shock. If your basement has
water or moisture on floor, do not walk on wet area until all
power has been turned off. If shut-off box is in basement,
call electric company or hydro authority to shut-off service
to house, or call your local fire department for instructions.
Failure to follow this warning can result in fatal electrical
shock. Remove pump and repair or replace.
DESCRIPTION
This Submersible Sump Pump is designed for home sumps.
Unit is equipped with a 3-prong grounding-type power cord. The
permanent split capacaitor 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.
Pump water only with this pump. Not designed for use as a
swimming pool drainer.

INSTALLATION
1. Install pump in sump pit with minimum diameter of 14"
(356mm). Sump depth should be 14" (356mm). Construct
sump pit of tile, concrete, steel or plastic. Check local codes
for approved materials.
2. Install pump in pit so that switch operating mechanism
has maximum possible clearance.
3. Pump should not be installed on clay, earth or sand sur-
faces. Clean sump pit of small stones and gravel which
could clog pump. Keep pump inlet screen clear.
NOTICE: Do not use ordinary pipe joint compound on
plastic pipe. Pipe joint compound can attack plastics.
4. Install discharge plumbing. When using rigid pipe, use
plastic pipe.
Slip rubber coupling over pump discharge. Install and
tighten first clamp. Place second clamp loosely over cou-
pling. Slip coupling over discharge pipe. Clamp hose
tightly with second clamp.
NOTICE: Discharge piping should be as short as possible
to reduce pipe friction losses. Discharge
pipe diameter should be equal to or larger than discharge
size of pump. Smaller pipe diameters will restrict capacity of
pump and reduce performance. Do no use flexible dis-
charge pipe in any permanent installation.
pump may allow pump movement, switch interfer-
ence and prevent pump from starting or stopping.
If a flexible discharge hose is used, make sure pump is
secured in sump to prevent movement.
5. To reduce motor noise and vibrations, a short length of
rubber hose (e.g. radiator hose) can be connected into
discharge line near pump using suitable clamps.
6. Pumps have an internal check valve to prevent flow back-
wards through pump when it is shut off.
7. Power Supply: Pump is designed for 115 V., 60 Hz., opera-
tion and requires a minimum 15 amp individual branch cir-
cuit. Both pump and switch are supplied with 3-wire cord
sets with grounding-type plugs. Switch plug is inserted
directly into outlet and pump plug inserts into opposite end
of switch plug.
be electrically grounded to a suitable electrical ground
such as a grounded water pipe or a properly grounded
metallic raceway or ground wire system. Do not modi-
fy cord or plug or cut off round ground pin.
8. Secure discharge line before starting pump.
9. If pump discharge line is exposed to outside sub-freezing
atmosphere, portion of line exposed must be installed so
any water remaining in pipe will drain to the outfall by
gravity. Failure to do this can cause water trapped in dis-
charge to freeze which could result in damage to pump.
10. After piping and check valve (if needed) have been
installed, unit is ready for operation.
11. Check operation by filling sump with water and observing
pump operation through one complete cycle.
