Failure to comply with national and local electrical and plumbing codes and within Franklin Electric 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. Refer to product data plate(s) for additional precautions, operating instructions and specifications. Failure to follow installation/operation procedures and all applicable codes may result in the following hazards: Risk of death, personal injury, or property damage due to explosion, fire, or electric shock. • Do not use to pump flammable or explosive fluids such as gaso- line, 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 posi- tion and tag it to prevent unexpected application of power. • If the disconnect panel is not accessible, contact the electric company to stop service. High voltages capable of causing severe injury or death by electrical shock are present in this unit. • To reduce risk of electrical shock, disconnect power before work- ing on or around the system. More than one disconnect switch may be required to de-energize the equipment before servicing. • This product is supplied with a grounding conductor and ground- ing-type attachment plug. To reduce risk of electric shock, be cer- tain 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. • Check electrical outlets with a circuit analyzer to ensure power, neutral, and ground wires are properly connected. If not, a qual- ified, licensed electrician should correct the problem. • Wire pump system for correct voltages. • The pump has been evaluated for use with water only. Pump should only be used with liquids compatible with pump compo- nent 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. 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 abilities, or lacking in expe- rience 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. • An inoperative or malfunctioning pump could lead to flooding, resulting in personal injury or property damage. • In applications where property damage and/or personal injury might result from an inoperative or leaking pump due to power outages, discharge line blockage, or any other reason, an auto- matic back-up system and/or an alarm should be installed. • Do not run the pump dry. If run dry, the surface temperature of the pump will rise to a high temperature that could cause skin burns if touched and will cause serious damage to the pump. • Do not oil the motor. The pump’s motor housing is sealed, and contains a high-grade dielectric oil for heat transfer and lifetime lubrication. Use of other oils could cause serious electric shock and/or permanent damage to the pump. • Operation of this equipment requires detailed installation and operation instructions provided in this manual for use with this product. Read entire manual before starting installation and oper- ation. End User should receive and retain manual for future use. • Keep safety labels clean and in good condition. Risk of damage to pump or other equipment. • Do not use this pump for pumping sea water, beverages, acids, chemical solutions, or any other liquid that promotes corrosion as this can result in damage to the pump. • Do not run pump dry. For optimal cooling and to prolong the motor life, the liquid level being pumped should normally be above the top of the pump housing. • This pump is not suitable for pond applications. INTRODUCTION Product Description 3 INTRODUCTION Product Description This submersible pump is designed for use in basins or pumping stations and is suitable for pumping clean water or effluent gray water with up to 3/4" (19 mm) spherical semi-solids. Do not use the pump in applications where sewage or any other debris (gravel, sand, floating debris, etc.), abrasives, or corrosives are present. The pump motor is equipped with an automatic restart thermal protector and may restart unexpectedly. Activation of the thermal protector indicates that the motor is overloaded or overheated, which may be due to application prob- lems, such as a clogged pump impeller, a switch stuck in the on position, a dry running of the pump, a air-sealed pump, a short pump cycle, an excessively high or low voltage supply, or a pump, motor, bearings, or seal that may have reached the end of its useful life. This product is covered by a Limited Warranty for a period of 36 months from the date of original purchase by the con- sumer.
