 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.
 Verify 3-phase pumps for correct rotation prior to installing
pump(s) in basin. To change rotation, reverse any two of the
three power leads to the pump (not the ground). Code the
wires for reconnection after installation.
 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 104°F (40°C). Operating the
pump in fluid above this temperature can overheat the pump,
resulting in pump failure and excessive cavitation.
 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.
 Keep pump upright.
 Do not allow pump to freeze.
 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.
 Replacement impellers must match the part number of
original impeller installed from the factory. Do not trim
impellers without consulting the factory.

General Information

This manual contains important information for the safe
installation and use of this product. Make sure this manual is
provided to the owner of the equipment or to the responsible
party who maintains the system.
These LEP-Series pumps are to be used for handling septic
tank effluent, sewage, and drain (storm) water.
Provide pump serial number in all correspondence and
reports.
Complete the Start-Up Report as installation progresses.
Completed and submitted Report is required for warranty.
Retain Report for reference.
For ordinary locations, pumps are certified by CSA Group to
CSA and UL standards.
For hazardous locations, pumps are certified by CSA Group
to CSA, UL, and FM standards for use in hazardous locations
with division classification of Class 1, Division 1 Group C and
D; or as zone classified Class 1, Zone 1, and Group IIA and IIB.
Do not use in other hazardous locations.
Pumps must be serviced at a qualified hazardous motor
enclosure repair facility approved by Liberty Pumps. Any
unauthorized field repairs void warranty and hazardous
location ratings. Contact Liberty Pumps at 1-800-543-2550 to

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.

Contact Liberty Pumps customer service to report any damage or
shortage of parts.
Storage Before Use
 Protect the power and control cords from the environment.
 At no time shall the pump be stored within an incomplete wet
LEP-Series pumps are shipped from the factory ready for
installation and use. The pump shall be held 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 shall be covered to
protect it from water, dirt, vibration, etc. The cord ends must be
protected against moisture. Do not allow the pump to freeze.
Uninstalled pumps that are idle for periods of time greater than
three months should have cutters and impellers manually rotated
once a month to lubricate the upper (inner) and lower (outer) seals.

Operating Constraints
Visually check the pump and any spare parts for damage.
Check for damaged electrical wires, especially where they exit
the motor housing.
RISK OF ELECTRIC SHOCK
Unprotected power and control (switch) cords can allow water
to wick through ends into pump or switch housings, causing
surroundings to become energized.
