SAFETY INSTRUCTIONS
1. Do not pump flammable or explosive liquids such as oil, gasoline, kerosene, ethanol, etc. Do not use in the
presence of flammable or explosive vapors. Using this pump with or near flammable liquids can cause an
explosion or fire, resulting in property damage, serious personal injury, and/or death.
2. ALWAYS disconnect the power to the pump before servicing.
3. Do not touch the motor housing during operation. The motor is designed to operate at high temperatures. Do not
disassemble the motor housing.
4. Do not handle the pump or pump motor with wet hands or when standing on a wet or damp surface, or in water
before disconnect the power.
5. Release all pressure and drain all water from the system before servicing any component.
6. Secure the discharge line before starting the pump. An unsecured discharge line will whip, possibly causing
personal injury, and/or property damage.
7. Extension cords may not deliver sufficient voltage to the pump motor. Extension cords present a life threatening
safety hazard if the insulation becomes damaged or the connection ends fall into water. The use of an extension
cord to power this pump is not permitted.
8. Wear safety goggles at all times when working with pumps.
9. This unit is designed only for use on 115 volts (single phase), 60 Hz, and is equipped with an approved 3-
conductor cord and 3-prong grounded plug. Do not remove the ground pin under any circumstances. The 3-prong
plug must be directly inserted into a properly installed and grounded 3-prong, grounding-type receptacle. Do not
use this pump with a 2-prong wall outlet. Replace the 2-prong outlet with a properly grounded 3-prong receptacle
(a GFCI outlet) installed in accordance with the National Electrical Code and local codes and ordinances. All
wiring should be performed by a qualified electrician.
10. Protect the electrical cord from sharp objects, hot surfaces, oil, and chemicals. Avoid kinking the cord. Do not use
damaged or worn cords.
11. Failure to comply with the instruction and designed operation of this unit may void the warranty. ATTEMPTING TO
USE ADAMAGED PUMP can result in property damage, serious personal injury, and/or death.
12. Ensure that the electrical circuit to the pump is protected by a 10 Amp fuse or circuit breaker.
13. Do not lift the pump by the power cord.
14. Know the pump and its applications, limitations, and potential hazards.
15. Secure the pump to a solid base. This will aid in keeping the pump in a vertical orientation. This is critical in
keeping the pump operating at maximum efficiency. It will also help prevent the pump from clogging resulting in
premature failure.
16. Periodically inspect the pump and system components to ensure the pump suction screen is free of mud, sand,
and debris. Disconnect the pump from the power supply before inspecting.
17. Follow all local electrical and safety codes, along with the National Electrical Code (NEC). In addition, all
Occupational Safety and Health Administration (OSHA) guidelines must be followed.
18. The motor of this pump has a thermal protector that will trip if the motor becomes too hot. The protector will reset
itself once the motor cools down and an acceptable temperature has been reached. The pump may start
unexpectedly if it is plugged in.
19. Ensure the electrical power source is adequate for the requirements of the pump.

20. Before using the pump, check the hose for holes or excess wear, which could cause leaks, and ensure the hose
is not kinked or making sharp angles. A straight hose allows the pump to move the greatest amount of water
quickly, and also check that hose connections are tight to minimize leaks.
21. This pump is made of high-strength, corrosion-resistant materials. It will provide trouble-free service for a long
time when properly installed, maintained, and used. However, inadequate electrical power to the pump, dirt, or
debris may cause the pump to fail. Please carefully read the manual and follow the instructions regarding
common pump problems and remedies.
PRE-INSTALLATION
APPLICATION
This submersible utility pump is designed for water removal applications. Pump water only with this pump. It can
drain or remove water from the following: pits, sinks, window wells, basements, swimming pool covers, boats, low
spot in yards, or other flooded areas.
This pump has not been tested or approved for use in swimming pools or in salt-water marine areas. This pump is
not designed to function as a permanently installed sump pump. It is also not engineered to be run continuously as
a “fountain” or “waterfall” pump.
Do not use where water recirculates.
Not designed for use as a swimming pool drainer.
Features:
Operating water depth: minimum 1 in.

INSTALLATION
CAUTION: Always use the handle to lift the pump. Never use the power cord to lift the pump. To avoid skin burns,
unplug the pump and allow time for it to cool after periods of extended use.
1. Connecting a 3/4 in. garden hose
Attach a 1 in. female adaptor (B) to the pump discharge.
Attach a garden hose with a 3/4 in. garden hose thread (not included) to the adaptor.
NOTE: NOTE: Be sure the 3/4 in. garden hose thread connector has a rubber gasket to
minimize water leaks.
NOTE: The larger the inside diameter and the shorter the length of hose, the less pressure
that is lost (or the larger the flow rate).
2. Connecting a 1-1/4 in. hose kit
If you would prefer to use a 1-1/4 in. hose kit (not included) in order to pump water
away more quickly.
Attach the adaptor (B) to the pump (A) discharge
Securely attach the hose kit (not included) to the adaptor (B).
WARNING: Secure the discharge hose before plugging in the pump. An unsecured
discharge hose may “whip” possibly causing personal injury, and/or property damage.
OPERATION
1. Plugging in the pump
Place the pump on a solid base in flooded area or any place that you
would like to remove water. Plug the pump into a 115 Volt GFCI power
outlet.
WARNING: Do not handle the pump or pump motor with wet hands or when
standing on a wet or damp surface, or in water.
NOTE: Place upright on a solid base.
NOTE: The pump must be standing in at least 1 in. (25.4 mm) of water before
you start it. The shaft seal is water lubricated and may be damaged if the
pump runs dry.
5
2. Operating the pump
Allow the pump to run and monitor its progress.
Unplug the pump when it has removed water down to approximately 1/8 in.
(3.2 mm).
Remove the pump and hose from the location when finished pumping. The
hose still has water that can drain back through the pump. Remove
remaining water with a squeegee, mop, sponge, towel, wet/dry vac, etc.
CAUTION: Do not run the pump dry. Operating the pump without water will
cause damage to the seals and will cause the pump to fail, thereby voiding the
pump’s warranty.
NOTE: After starting, the pump will lower the water level to 1/8 in. (3.2 mm) before losing suction. It will not pick up
water less than 1/8 in. (3.2 mm) deep when running and will not operate successfully if started in only 1/8 in. (3.2 mm)
of water.
Airlock
This pump is a centrifugal utility pump, designed to efficiently remove water. However, it cannot move air. If air is
trapped inside the pump (a condition called “airlock”), the pump cannot pump water out even though the pump is
completely submerged. This unit does not have an anti-airlock hole. When you use the pump, please drain the water
out of the garden hose, keep the end of the hose out of the water, and plug in the power cord, starting the pump.
CARE AND CLEANING
CAUTION: Always use the handle to lift the pump. Never use the power cord to lift the pump. To avoid skin burns,
unplug the pump and allow time for it to cool after periods of extended use.
Do Do Not
When the power is disconnected, inspect the pump
suction screen and remove all debris, then plug the
pump back into the grounded (GFCI) outlet.
Do not disassemble the motor housing. This
motor has NO repairable internal parts, and
disassembly may cause leakage or dangerous
electrical wiring issues.
Do not lift up the pump by the power cord.
To clean a pump clogged with debris:
Unplug the pump from electrical power.
Remove debris from the screen (3).
Remove the screws (4) and take out the volute (3) from the pump and clean
the debris on the shaft (1) and impeller (2).
Reassemble the volute (3).
