Safety Precautions
Accidental contact with electrically live parts, items, fluid, or
water can cause serious injury or death.
Always disconnect pump(s) from power source(s) before
handling or making any adjustments to either the pump(s),
the pump system, or the control panel.
All installation and maintenance of pumps, controls,
protection devices, and general wiring shall be done by
qualified personnel.
All electrical and safety practices shall be in accordance with
the National Electrical Code
Health Administration, or applicable local codes and
ordinances.
Do not remove cord and strain relief, and do not connect
conduit to pump.
Pump shall be properly grounded using its supplied
grounding conductor. Do not bypass grounding wires or
remove ground prong from attachment plugs. Failure to
properly ground the pump system can cause all metal
portions of the pump and its surroundings to become
energized.
Do not handle or unplug the pump with wet hands, when
standing on damp surface, or in water unless wearing
Personal Protective Equipment.
Always wear dielectric rubber boots and other applicable
Personal Protective Equipment (PPE) when water is on the
floor and an energized pump system must be serviced, as
submerged electrical connections can energize the water. Do
not enter the water if the water level is higher than the PPE
protection or if the PPE is not watertight.
Do not lift or carry a pump or a float assembly by its power
cord. This will damage the power cord, and could expose the
electrically live wires inside the power cord.
The electrical power supply shall be located within the length
limitations of the pump power cord, and for below grade
installations it shall be at least 4 ft (1.22 m) above floor level.
Do not use this product in applications where human contact
with the pumped fluid is common (such as swimming pools,
fountains, marine areas, etc.).
Protect the power and control cords from the environment.
Unprotected power and control (switch) cords can allow water
to wick through ends into pump or switch housings, causing
surroundings to become energized.
Single-phase 208/230V pumps shall only be operated without
the float switch by using the circuit breaker or panel
disconnect.
Some products may have internal capacitors that could cause
shock. Avoid contact with plug ends after removing from
energy source.
Do not use metal or any other electrical conducting material
to raise the float or contact anything inside an electrically live
sump pit.
Do not use an extension cord to power the product. Extension
cords can overload both the product and extension cord
supply wires. Overloaded wires will get very hot and can catch
RISK OF FIRE
on fire.
This product requires a separate, properly fused and
grounded branch circuit, sized for the voltage and amperage
requirements of the pump, as noted on the nameplate.
Overloaded branch circuit wires will get very hot and can
catch on fire. When used, electrical outlets shall be simplex of
the appropriate rating.
For cord replacement: power cord must be of the same length
and type as originally installed on the Liberty Pumps product.
Use of incorrect cord may lead to exceeding the electrical
rating of the cord and could result in death, serious injury, or
other significant failure.
Do not use this product with or near flammable or explosive
fluids such as gasoline, fuel oil, kerosene, etc. If rotating
elements inside pump strike any foreign object, sparks may
occur. Sparks could ignite flammable liquids.
Sewage and effluent systems produce and may contain
flammable and explosive gases. Prevent introduction of
foreign objects into basin as sparks could ignite these gases.
Exercise caution using tools and do not use electronic devices
or have live, exposed electrical circuits in or around basins,
open covers and vents.
Manual pumps that have been factory constructed with a
power cord with no male attachment plug must use an
approved motor control panel. Do not wire a switch in series
with the pump power cord as this can overload the wires.
Overloaded wires get very hot and can catch on fire.
These pumps are not to be installed in locations classified as
hazardous in accordance with the National Electric Code
®
ANSI/NFPA 70.
In 208/230V installations, one side of the line going to the
pump is always “hot”, whether the float switch is on or off. To
avoid hazards, install a double pole disconnect near the pump
installation.
Vent basin in accordance with local code. Proper venting of
sewer and effluent gases alleviates poisonous gas buildup
and reduces the risk of explosion and fire from these
flammable gases.
Wear adequate Personal Protective Equipment when working
on pumps or piping that have been exposed to wastewater.
Sump and sewage pumps often handle materials that can
transmit illness or disease upon contact with skin and other
tissues.
Do not enter a pump basin after it has been used. Sewage and
effluent can emit several gases that are poisonous.
Do not remove any tags or labels from the pump or its cord.
Keep clear of suction and discharge openings. To prevent
injury, never insert fingers into pump while it is connected to
a power source.
Do not use this product with flammable, explosive, or
corrosive fluids. Do not use in a flammable and/or explosive
atmosphere as serious injury or death could result.
This product contains chemicals known to the State of
California to cause cancer and birth defects or other
reproductive harm. www.p65warnings.ca.gov.
A grinder pump contains metal parts that rotate at high
speeds. Be careful around pump base while power is
connected. Make sure that the pump is either in the tank or
clear from people and wires when in operation.
This pump has been evaluated for use with water only.
,
Wear Personal Protective Equipment as exposed bottom has
sharp edges.
Energizing the control panel or breaker for the first time is
potentially dangerous. Licensed electrical personnel should
be present when the panel or breaker is energized for the first
time. If faults caused by damage or poor installation practices
have not been detected, serious damage, injury or death can
RISK OF SERIOUS INJURY OR DEATH
result when power is applied.
Do not modify the pump/pump system in any way.
Modifications may affect seals, change the electrical loading
of the pump, or damage the pump and its components.
All pump/pump system installations shall be in compliance
with all applicable Federal, State, and Local codes and
ordinances.
Do not allow children to play with the pump system.
Do not allow any person who is unqualified to have contact
with this pump system. Any person who is unaware of the
dangers of this pump system, or has not read this manual, can
easily be injured by the pump system.
Verify a Redundant Check Valve Assembly (curb stop and
check valve) is installed between the pump discharge and
the street main, as close to the public right-of-way as
possible, on all installations to protect from system
pressures.
Do not dispose of materials such as paint thinner or other
chemicals down drains. Doing so could chemically attack and
damage pump system components and cause product
malfunction or failure.
Do not use pumps with fluid over 140°F (60°C). Operating the
pump in fluid above this temperature can overheat the pump,
resulting in pump failure.
Do not use pump system with mud, sand, cement,
hydrocarbons, grease, or chemicals. Pump and system
components can be damaged from these items causing
product malfunction or failure. Additionally, flooding can
occur if these items jam the impeller or piping.
Do not run dry.
The Uniform Plumbing Code® states that sewage systems
shall have an audio and visual alarm that signals a
malfunction of the system, to reduce the potential for
property damage.
Do not position the pump float directly under the inlet from
drain tile or in the direct path of any incoming water.
Any PRG-Series system discharge can be reduced to 1-1/4”.
Keep pump upright.
At no time should the pump be stored within an incomplete
wet pit. The pump should not be placed into the pit until it
can be fully operational.
Do not allow the pump to freeze.
General Information
Before installation, read these instructions carefully.
Each pump is individually factory tested to ensure
proper performance. Closely following these
instructions will eliminate potential operating
problems, assuring years of trouble-free service.
PRG-Series pumps are to be used for handling
septic tank effluent, sewage, and drain (storm)
water.
Provide pump serial number in all correspondence.
Pumps are CSA certified to CSA and UL®
standards.
Pumps must be serviced at a qualified repair facility
approved by Liberty Pumps. No repair work should
be carried out during the warranty period without
prior factory approval. Any unauthorized field
repairs void warranty. Contact Liberty Pumps at
1-800-543-2550 to locate the closest authorized
service center.
Operating Constraints
It is extremely important to verify that the pump
has been sized correctly for the intended
installation. The operating point of the pump must
lie within the acceptable range as outlined by the
applicable Liberty Pumps performance chart.
Operating the pump outside of the recommended
range can invalidate the CSA Certification of the
pump and can also cause damage and premature
failure. Operating outside of the recommended
range can cause the pump to exceed its rated
nameplate amp draw, which will void the pump
certification. It can also cause motor overheating,
cavitation, excessive vibration, clogging, and poor
energy efficiency.
Inspection and Storage
Initial Inspection
The pump should be immediately inspected for damage that may
have occurred in shipment.
1.Visually check the pump and any spare parts for damage.
2.Check for damaged electrical wires, especially where they exit
the motor housing.
Contact Liberty Pumps customer service to report any damage or
shortage of parts.
Storage Before Use
RISK OF ELECTRIC SHOCK
Protect the power and control cords from the environment.
Unprotected power and control (switch) cords can allow water
to wick through ends into pump or switch housings, causing
surroundings to become energized.
At no time shall the pump be stored within an incomplete wet
pit. The pump shall not be placed into the pit until it can be
fully operational.
Do not allow the pump to freeze.
Pumps are shipped from the factory ready for installation and use.
Hold the pump in storage if the pump station is not complete.
If storage is necessary, the pump should remain in its shipping
container. It should be stored in a warehouse or storage shed that
has a clean, dry temperature-stable environment where the pump
and its container are covered to protect it from water, dirt,
vibration, etc. The cord ends must be protected against moisture.
Uninstalled pumps that are idle for greater than three months
should have cutters and impellers manually rotated once a month
to lubricate the seals.
Installed pumps that are idle for greater than one month should
have cutters and impellers manually operated through the breaker
panel once a month to lubricate the seals. For automatic models,
turn off the breaker, unplug the piggyback switch, and plug the
pump directly into receptacle. Turn the breaker on for 30 seconds,
then turn the breaker off. Plug the piggyback switch back in. Refer
to Piggyback Switch Operation on page 8.
