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.
