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 all 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
automatically 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.
Function:
Operating water depth: minimum 1-1/2 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 garden hose with a 3/4 in. garden hose thread (not included) to the pump outlet.
NOTE: Be sure the hose end has a rubber washer tominimize water leaks.
NOTE:The larger the inside diameter and the shorter the length of hose,theless 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 to the pump discharge.
 Securely attach the hose kit (not included) to the adaptor.
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 a flooded area or anyplace 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 will not start working unless the water level is over 1-1/2 in.
Operating Cycle for Automatic Utility Pump
 When first plugged in, pump runs for 30 seconds and checks for water
 If there is water (approximately 1-1/2 in. or more), the pump will remove water down to ~1/4 in.
 If there is no water, pump will shut off for 15 seconds, then run for 10 seconds checking for water. If there still is no
water, this cycle repeats 3 times.
 If still no water, pump shuts off for 2 minutes, then turns on again for 10 seconds checking for water. This cycle then
repeats as long as there is no water and pump is plugged in
 As soon as approximately 1-1/2 in. of water fills the area around the pump, the pump will begin pumping again after
the 2 minute cycle. Cycle above will repeat after water is removed.

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 two anti-airlock holes. 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 plugin
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!
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.
 Unscrew the stainless screws (7), and remove the screen (6), unscrew the stainless screws (5), and remove the
volute (4), and the seal gasket (3). Use a flathead screwdriver to hold the shaft (1), then turn the impeller (2)
counterclockwise to release the impeller (2).
 Reassemble.
