nameplate provides a record of specific pump information.

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
basin. The pump shall not be placed into the basin until it can
be fully operational.
 Do not allow the pump to freeze.
XLE-Series 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.
Installed pumps that are idle for greater than one month should
have impellers manually operated through the breaker panel once
a month to lubricate the seals.

Pump System Components

Control Panel
 Float switches must be connected to an intrinsically safe
XLE-Series pumps require a separate, approved pump control
device or panel for automatic operation. Operation 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.
The control panel shall be installed outside the hazardous area
and appropriately isolated and sealed to prevent any potential
ignition or explosion. Only approved controls that have
intrinsically safe float switch connections shall be used. 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 XLE-Series pump to an
existing control panel, verify the panel is correctly sized and
equipped for the pump.
3-phase models require overload elements selected or adjusted in
accordance with the control instructions. The control panel shall
have provisions for the thermostat that open the motor
contactors. Do not exceed voltage/current combinations for the
thermostat: 16 Vdc/20 Amps, 115 Vac/22 Amps, 277 Vac/8 Amps,
and 600 Vac/4 Amps. All models have a surface temperature (T)
class rating of T4; however, if thermostat is not connected on
3-phase models, the T class drops to T3.
Intrinsically safe control panels designed for use with the
XLE-Series pumps available from Liberty Pumps can be found at

1-phase pumps require a panel-mounted run capacitor. Refer to
