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 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. 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.
• If the disconnect panel is not accessible, contact the electric company to stop service.

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. More than one disconnect switch may be required to de-energize the equipment before servicing.
•  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.
• The pump includes a grounding connector. To reduce risk of electric shock, be certain that it is properly connected to ground.
• To avoid hazards when installing or servicing, install a double-pole disconnect near the pump installation.
• Use an appropriate discharge resistor to discharge the capacitor prior to working on the motor.
• 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 Association (OSHA), or Canadian Elec-trical Code (CEC).
•  Employ a licensed electrician.

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 abilities, or lacking in experi-ence and expertise, unless supervised or instructed. Children may not use the equipment, nor may they play with the unit or in the immediate vicinity.
•  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 your pump.
•  Equipment can start automatically. Lockout-Tagout before servicing equipment.
• The pump has been evaluated for use with water only. Pump should only be used with liquids compatible with pump component materials.
•  An inoperative or malfunctioning pump could lead to flooding, resulting in personal injury or property damage.
• Pump may become hot during operation. Allow pump to cool before servicing.
•  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.
• Keep safety labels clean and in good condition.
•  Keep work area clean, well-lit, and uncluttered.
• Wear safety glasses while installing or performing maintenance on the pump.

INSTALLATION Typical Installation

Pump Location

• Install the pump in a clean, dry, and ventilated location shielded from direct sun and precipitation.
• Provide adequate room for future servicing, protection from freezing temperatures, flooding, and equipment drainage.
• Bolt unit down evenly on a good foundation, preferably concrete, to prevent unnecessary stresses from pump movement.
• Install as close as possible to water source to minimize suction piping length.

Piping Instructions

• Properly support all suction and discharge piping to avoid strain on the pump.
• Piping should match the pump inlet and outlet connection sizes.
• For long runs, increase connections by one pipe size.
• Use pipe thread sealant.
• Avoid the use of unions on the suction line if possible. All suction line connections must be airtight.
• Do not over-tighten piping connections.

Suction Line

Suction Lift Applications

NOTE: The total suction lift should not exceed 25 feet.

1. Install a new, clean pipe or hose.
   • Make sure piping rises vertically or is sloped continually upward from the water source to the pump inlet connection.
   • Check that there are no high spots that cannot be evacuated of air during the priming process.
2. Install a strainer at the end of the suction line.
   • Ensure the strainer remains well submerged at all times.

Discharge Line

1. Tighten the discharge pipe, using an opposing pipe wrench on the pump discharge.
2. Install a check valve.
   • All discharge piping must have a pressure rating capable of withstanding the incoming inlet pressure plus the pump’s maximum shut-off head pressure.
     IMPORTANT: Do not operate the pump under a no-flow/shut-off head condition.

Electrical Connections

WARNING

Risk of severe injury or death by electrical shock.

1. An electrician should be employed to do the wiring.

2.  Provide a separate circuit from the distribution panel to the pump unit, properly protected with a fuse or circuit breaker.

3. Install a proper fused disconnect switch in the line. Make sure the correct gauge of cable is used to carry the load.
   IMPORTANT: Undersized wire between the motor and the power source will adversely limit the starting and load carrying abilities of the motor.

4. Wire the motor according to the motor nameplate to achieve clockwise rotation when viewed from the motor end.

   • Very long leads will require a larger cable.
   • If needed, remove motor end compartment for viewing.

5. Make sure the insulated green or bare ground wire is securely connected to the green ground termi-nal screw on the motor terminal board.

6. For 3-phase motors, install a separate manual thermal overload switch or a magnetic starter with proper size heater elements.

   • Failure to provide proper overload protection to the motor will void any warranty.

OPERATION

Risk of severe injury or death by electrical shock, high temperatures, or pressurized fluids.

• To reduce risk of electrical shock, disconnect power before working on or around the system.
• Do not continuously run pump against closed discharge. Release all system pressure before working on any com-ponent.

NOTICE

Risk of damage to pump or other equipment.

Do not let the unit run dry (without liquid). It is designed to be cooled by pumping fluid. The seal may be damaged and the motor may fail if the pump is allowed to run dry.

1.  Prime the pump.
   • Remove priming plug.
   • Pour water into the priming port.
   • Fill the pump and suction line with water.
   • Rotate motor shaft to let air in casing escape.
   • Refill at the priming port and replace priming plug.
2. If installing a 3-phase motor, check pump rotation by turning on power for a second.
   • The impeller must rotate in a counterclockwise direction while facing the pump from the front of the casing.
   • If direction is wrong, interchange any two of three wires either at the motor or starter.
3. Start the pump.
4.  Gradually open the discharge valve to the halfway point.
   • If the pump does not deliver water within seconds, stop the motor and prime pump again.
   • Several starting attempts may be necessary to expel all air from the pump and suction lines.
5. Once the pump is fully functioning, completely open the discharge valve and a system outlet.

MAINTENANCE

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.

NOTE: For replacement parts, consult the catalog available on www.FranklinWater.com.

• Check the pump periodically for loose or rubbing parts.
