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 Red Lion recommendations may result in elec-
trical 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 operating instructions and specifications.
Failure to follow installation or 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, 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.
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 prop-
erly connected to ground.
• To avoid hazards when installing or servicing, install a double-pole disconnect near the pump instal-
lation.
• Use an appropriate discharge resistor to discharge the capacitor prior to working on the motor.
• This pump has not been investigated for use in swimming pool or marine areas.
• 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 Electrical Code (CEC).
• Employ a licensed electrician.

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.
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 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.
• Do not run the pump dry. If run dry, the surface temperature of the pump will rise to a high tempera-
ture 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 com-
patible with pump component materials.
• An inoperative or malfunctioning pump could lead to flooding, resulting in personal injury or prop-
erty 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.

Piping Instructions
1. Install a new, clean pipe for the suction line.
NOTE: Do not exceed 25 feet of total suction lift.
• Make sure piping rises vertically or is sloped continually upward from the water source to the
pump inlet connection with no high spots.
• Ensure that piping matches the pump connection sizes.
• Avoid the use of unions if possible.
• For long runs, increase connections by one pipe size.
2. Use pipe thread sealant on suction piping for airtight connections.
3. Install a strainer at the end of the suction line.
• Ensure the strainer remains well submerged at all times.
4. Install discharge piping.
5. Tighten the discharge pipe, using an opposing pipe wrench on the pump discharge.
• Ensure that piping matches the pump connection sizes.
• Avoid the use of unions if possible.
• For long runs, increase connections by one pipe size.
6. 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.
7. Use pipe thread sealant on discharge piping for airtight connections.
Electrical Connections
1. Employ an electrician.
2. Provide a separate circuit from the distribution panel to the pump unit, properly protected with a
fuse or circuit breaker.
Risk of damage to pump or other equipment.
• Support pump and piping when assembling and when installed.
• Do not over-tighten piping connections.
Risk of severe injury or death by electrical shock.
• To reduce risk of electrical shock, disconnect power before working on or around the system.
Risk of damage to pump or other equipment.
• Failure to provide proper overload protection to the motor will void the warranty.

OPERATION
Electrical Connections

3. Install a proper fused disconnect switch in the line.
• Make sure the correct gauge of cable is used to carry the load.
4. Wire the motor according to the motor nameplate to achieve clockwise rotation.
• If needed, remove motor end compartment for viewing.
• Very long leads will require a larger cable.
• Make sure the insulated green or bare ground wire is securely connected to the green ground
terminal screw on the motor terminal board.
OPERATION
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. Start the pump.
3. 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.
NOTE: Several starting attempts may be necessary to expel all air from the pump and suction
lines.
4. Once the pump is fully functioning, completely open the discharge valve and a system outlet.
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 component.
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.
