Carefully read, understand and follow all safety instructions.
Read these warnings carefully. Know the application and limitations of this pump. Failure to follow these warnings could result in serious bodily injury and/or property damage.
DANGER! Risk of electric shock. Disconnect and lock out power supply before removing old pump or installing or servicing this pump.
DANGER! Risk of electric shock. This pump is supplied with a grounding conductor and grounding type attachment plug. To reduce the risk of electric shock, ensure that it is connected only to a properly grounded, grounding type receptacle. For added safety, it is highly recommended to connect this pump to a GFCI (Ground Fault Circuit Interrupter) outlet.
WARNING! The installation of this pump must be in accordance with the National Electric Code (NEC), Uniform Plumbing Code (UPC), International Plumbing Code (IPC) as well as all applicable local codes and ordinances.
CAUTION! Do not install this pump in any location classified as hazardous by the National Electric Code, ANSI/NFPA70.
CAUTION! Do not use this pump to pump flammable or explosive fluids such as gasoline, kerosene, etc. Do not use this pump in flammable or explosive environments. Use only with liquids compatible with pump component materials.
WARNING! Risk of electric shock. This pump has not been investigated for use in swimming pool or marine areas.
WARNING! Risk of electric shock. Do not use the power cord to install or carry the pump. Always use the handle. The cord may pull apart, exposing bare wires which could cause a fire or electric shock. Use the handle supplied with the pump for installing and transporting the pump.
WARNING! Do not run pump dry. This pump relies on water for cooling. Running the pump dry can cause the pump to overheat and the possibility of burns to anyone that handles the pump. Running the pump dry will void the warranty.
WARNING! Do not use this pump for potable/drinking water. Use only in applications for which the pump is designed.
WARNING! Ensure that the electric outlet is within the reach of the power supply cord. Do not use an extension cord. Extension cords that are too long or too light do not deliver sufficient voltage to the pump motor. More importantly, they present a safety hazard if the insulation were to become damaged or the connection end were to fall into the water.
CAUTION! This pump motor is equipped with an automatic resetting thermal protector and may restart unexpectedly.
SAFETY CONTINUED
WARNING! This pump is not intended to pump water softener discharge (brine) or condensate. Pumping these liquids could cause damage to the pump and will void the warranty.
CALIFORNIA WARNING: Cancer risk from exposure to Vinyl Chloride. See www.P65Warnings.ca.gov.
WARNING! Keep hands clear of suction and discharge openings. To prevent injury, never insert fingers into pump while it is plugged in.
WARNING! Do not handle this pump with wet hands or while standing on wet or damp surfaces or in water.
NOTE: This pump is not designed as a waterfall, pond or fountain pump. Use of this pump for waterfalls, ponds or fountains will void the warranty.
NOTE: This pump is UL certified and meets CSA standards for safety.

SETUP
UNPACKING
Upon receiving the pump, it should be inspected for damage or missing parts.
INSTALLATION
-
Connect a hose to the pump discharge. Use either the supplied garden hose adapter or other hose fitting.
-
Place the pump on a solid surface in at least 1" of water. Do not place the pump directly in mud, sand, silt or on rocky surfaces, as these materials can clog or cause damage to the pump.
NOTE: To keep friction loss as low as possible, do not use a hose that is smaller than 3/4".
OPERATION
- Connect the plug into a 120-Volt AC grounded outlet. The use of a GFCI is strongly recommended.
- The pump will not remove all water. It will drain water down to approximately 1/2" of the floor. Disconnect the pump from the power supply when the pump stops moving water.
CAUTION! Do not let the pump run dry. The pump depends on water for cooling and lubrication. Operating the pump without water may cause the motor to overheat or cause damage to internal parts. It may also shorten the life of the pump.
- This pump is equipped with an anti-airlock hole. A stream of water will emit from this hole when the pump is operating. This is a normal feature of this pump. The anti-airlock hole should be cleaned periodically to prevent the pump from becoming airlocked.
CAUTION! The pump motor is thermally protected. It is not recommended for pumping liquids over 120°F. The thermal overload protector will automatically shut down the pump in an overheat/overload situation. The pump will reset itself once the pump cools down. This overload is designed as a safety device, and it will fail after repeated use. Normal operation is for fluids between 32°F–120°F.
AIRLOCK
When a pump airlocks, it runs but does not move any water. An airlock will cause the pump to overheat and fail. This pump has an anti-airlock hole in the bottom of the pump housing. If you suspect an airlock, unplug the pump, clean out the anti-airlock hole with a paper clip or piece of wire, and restart the pump.
PERFORMANCE
Height, pipe diameter restriction and hose length will reduce the pump output performance. It is recommended to use the same size or larger pipe/hose as the pump discharge for optimum performance. The performances listed below were obtained by using 114 " pipe. The use of a garden hose will reduce the output depending on size and length of hose used.

MAINTENANCE
DANGER! Risk of electric shock. Always disconnect the power supply before attempting to install, service or perform maintenance on the pump.
WARNING! All repairs must be made by an authorized service center.
CAUTION! This submersible pump contains oil which may become pressurized and hot under normal operating conditions. Allow the pump to cool for 2–3 hours before servicing.
- The pump motor is hermetically sealed in the housing and does not require any service. Disassembly of the motor housing or modification of the power cord voids the warranty.
- Periodically check the removable intake screen for obstructions. Clean if necessary.
- Inspect the impeller for signs of wear and obstructions.
- Inspect the power cord for signs of damage or wear. Do not operate the pump if the cord is damaged or worn.
TROUBLESHOOTING
| OPERATING ISSUE CAUSES RECOMMENDATIONS | ||
| Pump does not start or run. | Pump is not plugged in; switch breaker is off.Check for blown fuses, tripped circuit breakers or tripped GFCI outlets.Motor thermal protector tripped. | Plug pump in or turn on switch/breaker.Replace fuse, reset breaker or reset GFCI outlet.Allow pump to cool. Pump will automatically reset. |
| Pump runs but moves little or no water. | Clogged intake screen.Clogged discharge hose/pipe.Impeller obstructed.Frozen discharge hose/pipe.Pump is airlocked.Low line voltage.Worn, damaged or clogged pump parts.Discharge head exceeds pump capacity. | Clean or replace screen.Remove clog.Remove obstruction/debris.Allow hose/pipe to thaw.Clean out airlock hole with a paper clip or pipe cleaner.Check wire size and increase if necessary.Inspect for wear, damage or clog and clean or replace if necessary.If pumping height is over 25', the pump will not move water.
