This is an Instructional Guide on how to reset a Portable Control Unit using the GFCI

A Ground Fault Circuit Interrupter (GFCI) or Residual Current Device (RCD) is a device used to reduce the risk of electric shock. It shuts off an electric circuit when it detects that current is flowing along an unintended path, possibly through water or through a person. Since the GFCI detects ground faults, it can also prevent some electrical fires and reduce the severity of other fires by interrupting the flow of electric current.

Since the GFCI has the ability to stop power from going to the unit, it can be used for resetting the Portable Control Unit without the need to disconnect it from an electrical outlet. 

To perform a GFCI reset, you will need to press the TEST Button to stop the flow of power to the unit. The Portable Control Unit will shut off and all functions will temporarily deactivate. To restore power to the unit, press the RESET button. Once power returns to the unit, it will begin to circulate the water within the tub, however heat and jets functions will need to be manually activated. 

NOTE: Do not plug the GFCI into an extension cord. Your spa should be plugged directly into a dedicated household outlet to reduce chances of damage. Please also ensure that the plug makes full contact with the outlet. If water gets into the GFCI plug, it will cause it to trip. Be sure to protect the plug from rain/snow.
