PERFORMANCE
ELECTRICAL & SWITCH SPECIFICATIONS
GENERAL SAFETY INFORMATION
Electrically powered sump pumps normally give
many years of trouble-free service when correctly
installed, maintained, and used. However, unusual
circumstances (interruption of power to the pump,
dirt/debris in the sump, flooding that exceeds the
pump’s capacity, electrical or mechanical failure in
the pump, etc.) may prevent your pump from functioning normally. To prevent possible water damage
due to flooding, consult your retailer about a secondary AC sump pump, a DC backup sump pump,
and/or a high water alarm. See the “Troubleshooting
Chart” in this manual for information about common
sump pump problems and remedies. For more information, see your retailer or call customer service at
1-800-468-7867.
1. Know the pump application, limitations, and
potential hazards.
2. Do not use in water with fish present. If any oil
leaks out of the motor it can kill fish.
3. Disconnect power before servicing.
4. Release all pressure within system before servicing any component.
5. Drain all water from system before servicing.
6. Secure discharge line before starting pump. An
unsecured discharge line will whip, possibly
causing personal injury and/or property damage.
7. Check hoses for weak or worn condition before
each use, making certain that all connections are
secure.
8. Periodically inspect sump, pump and system
components. Keep free of debris and foreign
objects. Perform routine maintenance as
required.
9. Provide means of pressure relief for pumps whose
discharge line can be shut-off or obstructed.
10. Personal Safety:
a. Wear safety glasses at all times when working
with pumps.
b. Keep work area clean, uncluttered and prop-
erly lighted – replace all unused tools and
equipment.
c. Keep visitors at a safe distance from work
area.
d. Make workshop child-proof – with padlocks,
master switches, and by removing starter
keys.
11. When wiring an electrically driven pump, follow
all electrical and safety codes that apply.
12. This equipment is only for use on 115 volt
(single phase) and is equipped with an
approved 3-conductor cord and 3-prong,
grounding-type plug.

Installation and Operation 3
To reduce risk of electric
shock, pull plug before servicing. This pump has not been investigated for
use in swimming pool areas. Pump is supplied
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 properly
grounded 3-prong receptacle installed in accordance with codes and ordinances that apply.
13. All wiring should be performed by a qualified
electrician.
14. Make certain power source conforms to requirements of your equipment.
15. Protect electrical cord from sharp objects, hot
surfaces, oil, and chemicals. Avoid kinking cord.
Replace or repair damaged or worn cords immediately.
16. Do not touch an operating motor. Modern motors
can operate at high temperatures.
17. Do not handle pump or pump motor with wet
hands or when standing on wet or damp surface,
or in water.
Hazardous voltage can shock,
burn or kill. 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. Remove
pump and repair or replace. Failure to follow this
warning can result in fatal electrical shock.
Do not lift pump by power cord.
FLOAT SWITCH INSTALLATION
Models equipped with vertical switches require some
assembly. See the Switch Assembly instructions on
Page 4. Models with tethered float switches are
ready for use.
INSTALLATION
1. Install pump in sump pit with minimum diameter
of 10" (254mm) for models equipped with vertical switches and 14" (356mm) for tethered float
switch models. Sump depth should be 16"
(406mm) for tethered models and 10” (254mm)
for vertically switched models. Construct sump
pit of tile, concrete, steel or plastic. Check local
codes for approved materials and for proper
installation.
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 surfaces. 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. Use rigid plastic pipe
and wrap threads with TeflonTMtape. Screw pipe
into pump hand tight plus 1-1/2 turns.
Risk of flooding. If a flexible
discharge hose is used,
make sure pump is secured in sump to prevent
movement. Failure to secure pump may allow
pump movement, switch interference and prevent pump from starting or stopping.
5. To reduce motor noise and vibrations, a short
length of rubber hose (1-7/8" (47.6mm) I.D., e.g.
radiator hose) can be connected into discharge
line near pump using suitable clamps.
6. Install an in-line check valve or an in-pump check
valve to prevent flow backwards through pump
when pump shuts off.
NOTICE: If your check valve is not equipped with
an air bleed hole to prevent airlocking pump, drill
a 1/8" (3.2 mm) hole in discharge pipe just above
where the discharge pipe screws into the pump
discharge. Be sure the hole is below the waterline
and the check valve to prevent air locks.
7. Power Supply: Pump is designed for 115 V., 60
Hz., operation and requires a minimum 15 amp
individual branch circuit. 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.
Pump should always be elec-
trically grounded to a suitable electrical ground such as a grounded
water pipe or a properly grounded metallic
raceway, or ground wire system. Do not cut off
round ground pin.
8. If pump discharge line is exposed to outside subfreezing 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 discharge to
freeze which could result in damage to pump.
9. After piping, check valve and float switch have
been installed, the unit is ready for operation.
10. Check the pump operation by filling sump with
water and observing pump operation through one
complete cycle. For switch settings see the Electrical
and Switch Specifications chart on Page 2.
Failure to make this opera-
tional check may lead to
improper operation, premature failure, and
flooding.

OPERATION
Risk of electric shock. Do not
handle a pump or pump motor
with wet hands or when standing on wet or damp
surface, or in water.
1. Shaft seal depends on water for lubrication. Do
not operate pump unless it is submerged in
water as seal may be damaged if allowed to run
dry.
2. Motor is equipped with automatic reset thermal
protector. If temperature in motor should rise
unduly, switch will cut off all power before damage can be done to motor. When motor has
cooled sufficiently, switch will reset automatically
and restart motor. If protector trips repeatedly,
pump should be removed and checked as to
cause of difficulty. Low voltage, long extension
cords, clogged impeller, very low head or lift, or
a plugged or frozen discharge pipe, etc., could
cause cycling.
3. Pump will not remove all water. If operating a
pump manually, and suddenly no water comes
out of the discharge hose, shut off the unit
immediately. The water level is probably very low
and the unit has broken prime.
Risk of electric shock. Before
attempting to check why unit
has stopped operating, disconnect power from
unit.
