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®, the Occupational Safety and
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.
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 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.
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.
These pumps are not to be installed in locations classified as
hazardous in accordance with the National Electric Code®,
ANSI/NFPA 70.
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.
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.
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 these 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 exert heavy pressure or run heavy equipment on the
backfill material as this could cause the tank to collapse.
Introduction
Pump, alarm, and control panel are supplied with their own
separate manuals. Ensure receipt of these manuals, and that they
are read and understood prior to installing and using this system.
Familiarity with the pump, alarm, and control panel is critical.
This manual provides a brief overview of the system, and deals
mainly with inspection and installation of the basin. It does not
cover the specifics of the pump, alarm, and control panel
operation. For questions, call Liberty Pumps customer service at
800-543-2550.
Identification
Information about the system can be found on a tag located on
the basin cover. This identifies the system model number as well
as the horsepower, voltage, and amp draw for the pump. Pump
tag is located on the pump. Duplicate pump tags are packaged
with the system. These should be mounted on the basin cover or
at the control panel for accessibility and immediate pump
information.
Inspection
Inspect the system upon arrival to ensure that there is no shipping
damage. Pay careful attention to the condition of the fiberglass
basin, control floats, pump guide rail brackets, and control panel.
Notify the carrier immediately if there is any damage.
Read all instructions and become familiar with the system’s
operation prior to proceeding with the installation.
Model Specifications
For a complete listing of pump models and their specifications,
refer to http://www.LibertyPumps.com/About/Engineering-Specs.
The pump nameplate provides a record of specific pump
information.
Basin Installation
This is a brief reference to the recommended methods and
procedures for installing Liberty Pumps basins to ensure that
damage or premature failure of the basin does not occur.
This section is not intended to serve as a basic instructional guide.
The installation of Liberty Pumps sump and sewage basins is a
specialized skill and is assumed that the individuals who install our
products and refer to this section will have basic understanding of
such procedures as excavating, backfilling, pipefitting, and
electrical work. No amount of written instruction by a
manufacturer or regulatory agency will convert an inexperienced,
under-supervised laborer into a skilled, experienced mechanic.
The ability to recognize and correctly respond to abnormal
conditions during a basin installation requires field experience as
well as mechanical aptitude. Figure 1 is provided for reference.
In addition to proper system engineering and competent
manufacturing, the use of basin installers who have both practical
experience and integrity to assist that the basin be installed
properly, constitutes the greatest protection from catastrophic
basin failure and liability exposure.
Basin Handling
General Handling
Although the exterior surfaces of the fiberglass basins are
designed to withstand normal handling, they can be damaged
during transportation and installation. Basins must not be
dropped, dragged, or handled with sharp objects, and with the
exception of the minimal movement involved in a visual
inspection, must not be rolled.
Unloading, Lifting, and Lowering
Under no circumstances are the use of chains or cables
around the basin shell permitted.
The proper way to move a basin is by lifting it, using chains or
cables with the optional lifting lugs (not more than a 30° angle), or
by using a non-marring sling around the basin. Before any
attempt is made to move a basin, verify that all equipment and
accessories have sufficient capacity and reach to lift and lower the
basin without dragging and/or dropping. Maneuver the basin with
guide ropes attached to the sides.
RISK OF SERIOUS INJURY OR DEATH

Pre-Installation Inspection
Confirm adherence to the project’s specifications before
installation. Physically and visually inspected basin, pumps, valves,
equipment, and piping materials before installation. Notify the
carrier immediately if there is any damage. If the basin or any of its
internal components are damaged, suspend installation until a
determination of the extent of damage can be made by Liberty
Pumps or its agent. Any repairs must be first authorized in writing
by Liberty Pumps and then be done in accordance with Liberty
Pumps instructions.
Storage
Store the basin in a secure, controlled area where the potential for
accidental damage or vandalism will be minimized. The storage
area must be free from sharp objects, rocks, and any other foreign
solutions or materials that could cause damage to the basin.
Chock the basin until it is needed for installation and, if windy
conditions are possible, secure the basin with non-marring
restraints of a size and number adequate for securing the basin.
Excavation
Locate all overhead and underground utilities before
excavating.
Excavation Considerations
The excavation must provide adequate space for the basin, piping,
and other buried equipment, and for the replacement and
compaction of backfill materials particularly around the basin
walls. The size, shape, and wall slope of the excavation should be
determined by soil conditions, depth of excavation, shoring
requirements, and if workers are required to enter the excavation,
safety considerations and federal, state, county, and municipal
regulations.
Excavation Location
Excavation for an underground basin must be made with due care
to avoid undermining foundations of existing structures and
contact with underground utilities. In the absence of building
codes or regulations, maintain a minimum distance of 5 feet plus
a slope of 45° from the bottom of the compacted sub-base to the
bottom of the adjacent structures, foundations, footings, and
property lines. Additional distances may be required to ensure
that any loading carried or created by the foundations and
supports cannot be transferred to the basin.
Maximum Basin Burial Depth
If burial depth is greater than the basin height, contact Liberty
Pumps to determine if additional wall reinforcement is required
and secure written authorization.
Excavated Materials Handling
Carefully store excavated materials that cannot be removed from
the job site as far from the edge of the basin excavation as
possible. Unless approved for use as backfill, securely store
excavation materials separate from the approved backfill
materials.
Work Area Safety
Safe installation procedures are the sole responsibility of the basin
installer. Work safety requirements are defined in US Department
of Labor 29 CFR 1926, Subpart P: Excavations.
Backfill
Careful selection, placement, and compaction of approved backfill
material is critical to a successful basin installation. Among the
common problems associated with basin leaks and premature
failures are:
•Use of incorrect backfill material
•Inadequate or improper placement or compaction
•Rocks, clods, or debris left in the excavation or basin
•Voids under or around the perimeter of the basin
•Failure to prevent the migration of backfill materials
Basin Placement
Placement of a basin on a concrete pad or compacted
sub-base smaller than the total basin bottom area or on
intermediate supports (saddles) will cause uneven
distribution of loads. This may contribute to structural failure
and is never permitted.
Cover the bottom of the basin excavation with suitably graded,
leveled, and compacted backfill material to a depth of at least 12”
(compacted sub-base). If a concrete hold-down/anti-flotation pad
is required, this bedding can be reduced to a depth of at least 6”.
Carefully lower the basin into the excavated area and center on
the compacted backfill or concrete pad.
Backfill Material
Ensure backfill material is clean, well granulated, free-flowing,
non-corrosive, and inert; free of ice, snow, debris, rock, or organic
material, all of which could damage the basin and interfere with
the compaction of the backfill material. The largest particles shall
not be larger than 3/4”. Not more than 3% (by weight) should
pass through a #8 sieve, and the backfill material must conform to
ASTM C-33, Paragraph 9.1 requirements. Approved backfill
materials include:
•Pea gravel, naturally rounded particles, with a minimum
diameter of 1/8” and a maximum diameter of 3/4”
•Crushed rock, washed and free-flowing angular particles
between 1/8” and 1/2” in size
Backfill Placement and Compaction
Compaction of backfill materials must be adequate to ensure the
support of the basin and to prevent movement or settlement.
Place backfill materials in 12” lifts and compacted to a minimum
soil modulus of 700 pounds per square foot.
Do not exert heavy pressure or run heavy equipment on the
backfill material as this could cause the tank to collapse.
