What is a GFCI outlet?

Chlorine Genie must be plugged into a GFCI outlet, please read below to understand the protection that GFCI outlets provide.

A GFCI (Ground-Fault Circuit Interrupters) outlet contains a sensor that monitors the flow of the electrical current through the wires, and when it senses a ground fault (in electrical terms, “fault” means any variation from the normal current), the GFCI, which also contains an internal switch, shuts off the flow of electricity in the outlet.

In other words, a GFCI outlet contains a sensor that will disconnect power if it senses a short. For the Chlorine Genie's purpose, having this protection is required due to the presence of water in and around the unit. Not powering the Chlorine Genie via a GFCI outlet presents significant risk and voids all part warranties.
