Before Getting Started
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 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
operty damage. Do not disassemble or repair unit unless
pr
described in this manual.
Refer to product data plate(s) for additional precautions, 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 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.

SAFETY INSTRUCTIONS
Before Getting Started
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
working on or around the system. More than one disconnect switch may be required to de-energize the equipment
before servicing.
• Be certain that this pump is connected to a circuit
equipped with a ground fault circuit interrupter (GFCI)
device if required by code.
• 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 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.
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.
Risk of bodily injury, electric shock,
or property 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 use this pump for pumping any liquid intended for
human consumption.
• Equipment can start automatically. Always unplug the
pump power cord and disconnect the electrical power
before servicing the pump or switch. Lockout-Tagout
before servicing equipment.
• 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 automatic 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 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.
• Do not wear loose clothing, jewelry, or anything that may
be caught in the rotating parts. Tie up long hair and
remove jewelry.

PRODUCT DESCRIPTION
Models
PRODUCT DESCRIPTION
This submersible pump is for use in basins or lift stations and is suitable for pumping clear water and other
non-explosive, non-corrosive liquids. Do not use the pump in applications where sewage or any other debris
(gravel, sand, floating debris, etc.), abrasives, or corrosives are present.
These products have been carefully tested, inspected, and packaged to ensure safe delivery and operation.
Please examine your pump carefully to ensure that no damage occurred during shipment. If damage has
occurred, please contact the place of purchase. They will assist you in replacement or repair, if required.
The pump motor is equipped with an automatic resetting thermal protector, and may restart unexpectedly.
Thermal Protector tripping is an indication of motor overloading or overheating, which can be caused by
application issues such as an obstructed pump impeller, float stuck in the ON position, pump running dry,
pump air-locked, pump short cycling, excessively high or low voltage supply, or possibly a pump, motor,
bearings, or seal that have reached the end of their useful life.

INSTALLATION
Physical Installation
Risk of severe injury or death by electrical shock.
• Always disconnect the electrical power before touching the pump or discharge.
• 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).
1. Pump must be installed in a suitable basin that is at least 18” (457 mm) deep, and in accordance with
local plumbing codes. Refer to
2. Clean any debris from the basin and set the pump in the center of the basin (refer to “Typical Installa-
tion” on page 6).
3. The pump must be placed on a hard, level surface. Never place the pump directly on clay, earth or
gravel surfaces. These surfaces contain small stones, gravel, sand etc. that may clog or damage the
pump and cause pump failure.
4. Do not attempt to restrict the intake side of these pumps. Restricting the intake may cause damage to
the seal and may starve the pump. If you require reduced flow rates, place a valve on the discharge side
of the pump. Or, if flexible vinyl tubing is used, a clamp can be used on the tubing to restrict the flow.
5. Connect discharge piping. Use pipe joint compound at all connections. Sump pumps can be piped to
discharge into the house drainage system, to a dry well, splash block, or to a storm drain, depending on
local plumbing codes. The discharge pipe should be as short as possible and contain as few elbows as
possible. The discharge pipe should be the same diameter, or larger than, the pump discharge size. A
smaller pipe will restrict capacity and reduce pump performance. The pump comes with a 1-1/2" FNPT
discharge and a 1-1/4” FNPT reducing bushing.
• Support the pump and piping while assembling and when installed. Failure to do so may cause the
piping to break, the pump to fail, motor bearing failures, etc.
• Always install a union in the discharge line just above the basin cover to allow for easy removal of
the pump for cleaning or repair.
6. A full flow check valve must be used in the discharge line to prevent back-flow of liquid into the basin.
A missing, improperly installed, or malfunctioning check valve can cause a pump to short-cycle due to
back-flow of the pumped fluid from the discharge plumbing back into the basin, significantly shorten
ing the life of the pump.
“Models” on page 4 for minimum basin diameters.
INSTALLATION
Physical Installation
-
Risk of property damage due to flooding.
• When a check valve is used, drill a relief hole 1/8 – 3/16" (3.2 – 4.8 mm) in diameter in the discharge
pipe. This hole should be located below the floor line between the pump discharge and the check
valve. Unless such a relief hole is provided, the pump could “air lock” and will not pump water even
though it will run.
7. Tape the pump and switch cords to the discharge pipe with electrical tape to keep the power cords
securely routed away from the pump inlet and any control floats.
8. Connect the pump to an appropriate power supply following the instructions in “Electrical Connec-
tions” on page 7.
