Electrical Connections
Risk of severe injury or death by electrical shock.
• Always disconnect the electrical power before touching the pump, discharge or electrical plug when water is
present in the area.
• Do not use the power cord for lifting the pump.
• Be certain that this pump is connected to a circuit equipped with a ground fault circuit interrupter (GFCI) device if
required by code.
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.
NOTE: Do not connect to a fan or any device that runs
intermittently.
• The fuses or circuit breaker should use a 15 A breaker.
IMPORTANT: If the power cord is damaged, the whole
unit must be replaced
The 9EC-CIA-RF, 9ECH-CIA-RF and 10ECH-CIA-RF pumps
have piggyback plugs on the switch cords.
1. Plug the pump cord into the float switch cord.
2. Plug the float switch cord into the outlet.
