This article shares the function to install an LCDI plug into a GCDM unit.
The GCDM units have a universal plug that can be plugged into the unit. To access this portion of the unit, we would need to remove the front panel and unscrew the screws to the metal box located at the bottom right of the unit. Once unscrewed, you can see the insert. Be sure to align the outlet to the plug and this step should be performed before plugging the other end into the receptacle.
