 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.
 Do not position the pump float directly under the inlet from
drain tile or in the direct path of any incoming water.
 Keep pump upright.
 Do not allow pump to freeze.
 At no time shall the pump be stored within an incomplete wet
basin. The pump shall not be placed into the basin until it can
be fully operational.

Inspection a nd Stora ge
Initial Inspection
Inspect pump immediately 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
 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
basin. The pump shall not be placed into the basin 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 impellers manually rotated once a month to lubricate
the seals.
Pump Design
Some LE and LEH-Series pumps come equipped with an air bleed
hole to help prevent airlock. A small spray of water from this hole
is normal while pump is running.
Pump System Components
Control Panel
Manual models (“M” suffix) and 3-phase models require a
separate, approved pump control device or panel for automatic
operation. Operation will be according to the control panel
selected. Refer to separate manufacturer’s instructions supplied
with the unit. Verify the electrical specifications for the control
panel properly match those of the pump. 3-phase models require
overload elements selected or adjusted in accordance with the
control or panel instructions.
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.
These pumps are to be used for handling septic tank
effluent, sewage, and drain (storm) water.
Provide pump serial number in all correspondence.
Pumps are certified by CSA Group 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.
