SAFETY INSTRUCTIONS
DANGER: Indicates a hazardous situation that, if not avoided, will result in death or serious injury.
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.
WARNING: indicates a hazardous situation that, if not avoided, could result in death or serious injury.
1. Release all pressure and drain all water from the system before servicing any component.
2. Secure the discharge line before starting the pump. An unsecured discharge line will whip, possibly causing
personal injury, and/or property damage.
3. 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.
4. Wear safety goggles at all times when working with pumps.
5. 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.
6. Protect the electrical cord from sharp objects, hot surfaces, oil, and chemicals. Avoid kinking the cord. Do not use
damaged or worn cords.
7. Failure to comply with the instruction and designed operation of this unit may void the warranty. ATTEMPTING TO
USE A DAMAGED PUMP can result in property damage, serious personal injury, and/or death.
8. Ensure that the electrical circuit to the pump is protected by a 10 Amp fuse or circuit breaker.
CAUTION: indicates a hazardous situation that, if not avoided, could result in minor or moderate injury.
1. Do not lift the pump by the power cord.
2. Know the pump and its applications, limitations, and potential hazards.
3. 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.
4. 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.
5. 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.
6. Do not run the pump dry. Operating the pump without water will cause damage to the seals and the pump to fail,
which voids the warranty.
IMPORTANT: indicates best practices not related to personal injury.
1. 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.
4
2. Ensure the electrical power source is adequate for the requirements of the pump.
3. 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 all hose connections are tight to minimize leaks.
4. 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.

SUBMERSIBLE UTILITY PUMP INSTALLATION
DANGER: 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.
DANGER: Always disconnect power source before attempting to install, service, or maintain the pump. Never handle
a pump with wet hands or when standing on wet or damp surface or in water. Fatal electrical shock could occur.
1. Connect the Garden Hose
Attach a 3/4 in. garden hose to the pump outlet. Use a garden hose
that is no longer than 25 ft.
2. Plug in the Pump
Place the pump on a hard surface in water that is at least 1-1/2 in.
deep. Do not place the pump directly on sand, dirt, or mud. Plug
the pump into a properly grounded 115V GFCI outlet. Be sure the
plug is secure and will not fall into the water. The pump should
start immediately.
If you need to pump water that is less than 1-1/2 in. deep, use the
Transfer function of the pump with the Suction Strainer – see next
page.
3. Operating the Pump
Allow the pump to run and monitor its progress. Unplug the
pump when it has removed water down to approximately 1/2 in.
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, which voids the pump’s warranty.
The pump may still run even when it is not pumping water.
Monitor the pump’s progress and promptly unplug the pump
before it runs dry to avoid damaging the motor.

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 pump has an anti-airlock hole. Air flows out through the anti-
airlock hole, eliminating the airlock so that the pump can operate properly. If
debris blocks the anti-airlock hole, unplug the pump, clean out the anti-airlock
hole, and restart the pump. Alternately, drain the water out of the garden hose,
keep the end of the hose out of the water, and plug in the power cord, restarting
the pump.
CAUTION: This hole is for anti-airlock purposes. Leakage of air or water is
NORMAL. DO NOT BLOCK THIS HOLE!
NON-SUBMERSIBLE TRANSFER PUMP INSTALLATION
DANGER: Always disconnect power source before attempting to install, service, or maintain the pump. Never handle
a pump with wet hands or when standing on wet or damp surface or in water. Fatal electrical shock could occur.
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.
