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.
LSG/LSGX-Series Omnivore grinder pumps are shipped from the
factory ready for installation and use. The pump should 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 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 impellers and cutters 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 Figure 3.

Pump Design

LSG/LSGX-Series grinder pumps are designed for continuous
underwater operation. The motor and pump form a close coupled,
watertight unit. The induction motor is insulated against heat and
moisture in accordance with Class B 265°F (130°C) regulations.
The motor is protected against damage from water entry by two
seals. The lower seal is a Viton lip seal and the upper seal is
mechanical, consisting of two silicon carbide faces.
The impeller and volute are designed for efficient flow
characteristics and clog-free operation. The hardened cutters
grind solids and fibrous matter into small particles that can be
safely pumped through small diameter piping.

Pump System Components

Control Panel
Manual LSG/LSGX-Series pumps require a separate, approved
pump control panel for automatic operation. Operation of these
models will be according to the control 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.
Mounting, installation, and wiring connections are specific to the
control panel used. Refer to the manufacturer's instructions
supplied with the unit.
IMPORTANT: When connecting an LSG/LSGX-Series pump to an
existing control panel, verify the panel is correctly sized and
equipped for the pump.
Control panels designed for use with the LSG/LSGX-Series pumps
available from Liberty Pumps can be found at http://

or contact Liberty Pumps.
LSG202M-C and LSGX202M-C models require a panel-mounted
start circuit consisting of a start capacitor, run capacitor, and start
relay, which are available separately. Refer to Table 1 for these
control panel components.
