Inspection a nd Stora ge
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
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.
Liberty Engineered Products 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 impellers and cutters manually rotated
once a month to lubricate the seals.

Pump System Components
Control Panel
All LGH02/LGV02-Series grinder pumps require a separate,
approved pump control panel for operation. Operation of these
models will be according to the control selected; see separate
operation instructions supplied with the unit.
IMPORTANT:
When connecting an LEP-Series pump to an existing
control panel, verify the panel is correctly sized and equipped for
the pump.
Control and power cords shall not be spliced, although a junction
box may be used. 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 panel instructions.
1-phase pumps require a motor start circuit (start capacitor, run
capacitor, start relay). Refer to Table
1 for the control panel
component kit.

Warranty
Pumps are certified by CSA® Group to CSA and UL®
standards.
Pumps must be serviced at a qualified repair facility
approved by Liberty Pumps. 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.
