Electrical Connections; Operation Testing - Little Giant 12E Series Owner's Manual

Electrical Connections

Connect the power cord to a constant source of power matching the pump nameplate voltage.
• The pump should be connected or wired to its own circuit, with no other electric receptacles or
equipment in the circuit. Do not connect to a fan or any device that runs intermittently.
• The fuses or circuit breaker should be of ample capacity.
• Connect to a circuit equipped with a ground fault circuit interrupter (GFCI) if required by code.
IMPORTANT: If the power cord is damaged, the whole unit must be replaced.
The 12E-CIA-RF pump has an automatic switch with a piggy-
back plug on the switch cords. For automatic operation, plug
the pump cord into the float switch cord. Plug the float switch
cord (with pump cord attached) into the GFCI outlet.

OPERATION TESTING

Risk of damage to pump or other equipment.
• Do not attempt to run the pump without water; this could result in permanent damage to the pump.
• If pump is run dry, it may damage pump and will void the warranty.
If the pump does not operate properly, consult
be found, please contact the place of purchase or an authorized service center.
Do not let the unit run dry (without liquid). It is designed to be cooled by pumping fluid. The seal may
be damaged and the motor may fail if the pump is allowed to run dry. Pump should be totally sub-
merged for proper cooling of the motor when pump is operated for extended periods.
If the unit is going to be idle for a period of time, refer to
not let the unit freeze. This may cause cracking or distortion that may destroy the unit.
Testing Automatic Pump Operation
When the 12E-CIA-RF pump is installed in a basin with a sealed cover, switch operation cannot be
observed. The basin cover will usually have a spare hole that is plugged with a rubber plug. This plug
can be removed and switch operation can be observed.
To test system operation, follow these steps:
1. Plug the power cord into a grounded receptacle with voltage consistent with the pump voltage, as
indicated on the pump nameplate.
2. Be sure the gate valve in the discharge line is open.
3. Run water into the basin until the pump is activated.
4. Make sure the pump and its float switch are functioning as intended.
