SAFETY INSTRUCTIONS

This equipment should be installed and serviced by technically qualified personnel who are familiar with the correct selection and use of appropriate tools, equipment, and procedures. Failure to comply with national and local electrical and plumbing codes and within Little Giant recommendations may result in electrical shock or fire hazard, unsatisfactory performance, or equipment failure.
Know the product’s application, limitations, and potential hazards. Read and follow instructions carefully to avoid injury and property damage. Do not disassemble or repair unit unless described in this manual.
Failure to follow installation or operation procedures and all applicable codes may result in the following hazards:
DANGER
Risk of death, personal injury, or property damage due to explosion, fire, or electric shock.

• Do not use to pump flammable, combustible, or explosive fluids such as gasoline, fuel oil, kerosene, etc.
• Do not use in explosive atmospheres or hazardous locations as classified by the NEC, ANSI/NFPA70.
• Do not handle a pump or pump motor with wet hands or when standing on a wet or damp surface, or in water.
• When a pump is in its application, do not touch the motor, pipes, or water until the unit is unplugged or electrically disconnected.
• If the power disconnect is out of sight, lock it in the open position and tag it to prevent unexpected application of power.

WARNING
Risk of severe injury or death by electrical shock.

• To reduce risk of electrical shock, disconnect power before working on or around the system.
• Wire pump system for correct voltage.
• Be certain that this pump is connected to a circuit equipped with a ground fault circuit interrupter (GFCI) device if required by code.
• Check electrical outlets with a circuit analyzer to ensure power, neutral, and ground wires are properly connected.
• Some pumps are supplied with a grounding conductor and grounding-type attachment plug. To reduce risk of electric shock, be certain that it is connected only to a properly grounded grounding-type receptacle. Do not remove the third prong from the plug. The third prong is to ground the pump to help prevent possible electric shock hazard. Do not use an extension cord.
• Some pumps are supplied with lead wires and are intended to be hardwired using a junction box or other approved enclosure. The pumps include a grounding connector. To reduce risk of electric shock, be certain that it is properly connected to ground.
• Check local electrical and building codes before installation. The installation must be in accordance with their regulations as well as the most recent National Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA).
• Do not use the power cord for lifting the pump.
• The pump should only be used with liquids compatible with pump component materials. If the pump is used with liquids incompatible with the pump components, the liquid can cause failure to the electrical insulation system resulting in electrical shock.

CAUTION
Risk of bodily injury, electric shock, or equipment damage.

• This equipment must not be used by children or persons with reduced physical, sensory or mental abilo- ties, or lacking in experience and expertise, unless supervised or instructed. Children may not use the equipment, nor may they play with the unit or in the immediate vicinity.
• Equipment can start automatically. Always unplug the pump power cord and disconnect the electrical power before servicing the pump or switch.
• The pump has been evaluated for use with water only.
• Operation of this equipment requires detailed installation and operation instructions provided in this manual. Read entire manual before starting installation and operation. End User should receive and retain manual for future use.

NOTICE
Risk of damage to pump or other equipment.

• If pump is run dry, it may damage pump and void the warranty.
• Periodically inspect pump and system components. Regularly check hoses for weakness or wear, making certain that all connections are secure.
• Schedule and perform routine maintenance as required and in accordance with “Maintenance” on page 4 of this manual.

INSTALLATION

Physical Installation

NOTE: This pump can be used inline or submerged. It is not self-priming and must be located below the water surface.

1. Place the pump in the water on a hard, level surface.
   • Always position the discharge above the suction port.
   • Never place pump directly on clay, earth, or gravel surfaces.
   • For use in outdoor fountains or ponds, attach an inlet screen to the intake.

2. Connect appropriate piping. Refer to “Specifications” on page 1.
   • For in-line systems, connect inlet piping.
   • If applicable, connect discharge piping.
   NOTE: Do not restrict or block the suction port.

3. If it is necessary to reduce the flow rate of the pump, adjust accordingly with the discharge flow control mechanism.

Electrical Connections
Connect the power cord to a constant source of power matching the pump nameplate voltage.

• The pump should be connected or wired to its own circuit, with no other equipment in the circuit.
• Do not connect to a fan or any device that runs intermittently.
• The fuses or circuit breaker should be of ample capacity.
• Connect to a circuit equipped with a ground fault circuit interrupter (GFCI) if required by code.

IMPORTANT: If the power cord is damaged, the whole unit must be replaced.

MAINTENANCE

Periodic Maintenance
Periodically observe the pump’s performance. If a decrease in flow is noted, clean the pump as follows:

1. Disconnect pump from power and remove from water source.

2. Disassemble the pump housing by removing the screws connecting it to the pump body.
   IMPORTANT: Do not open the motor housing. There are no field serviceable parts or maintenance required.

3. Carefully clean any debris from the impeller and pump housing.
   IMPORTANT: Do not remove the impeller from the motor shaft.

4. Replace the pump housing, taking care to also replace the O-ring in the groove on the pump body.

Storage

1. Refer to “Periodic Maintenance” on page 4 for cleaning.
2. Coat the pump housing, impeller, shaft, and seal with a general purpose oil.
3. Reassemble the pump.
4. Store in a dry place.

Troubleshooting

sur- face.
Low water flow from the pump| The pump intake is blocked| Remove debris blocking the intake screen or impeller.
The pump is not large enough| Select a larger capacity pump.
The flow control valve is mis-adjusted| Turn the flow control valve until the desired flow is reached.
Pump runs intermit- tently| The pump is too hot| Check to see that no debris is clogging the suction port.
