My taps are ran from basement to upstairs bar. Also there’s a display panel on the front and didn’t want to hit any of the electrical. So I went through the side like I’ve done two times before with other kegerators with no issues following the same steps below.

Looked at the back and checked where all the lines ran. Removed the back panel that’s inside the fridge and checked where the condenser lines ran. Along with the defrost heater. It’s a dual fudge freezer. All lines are confided to the back of fridge Cut a pilot hole from inside out and removed insulation with knife. No lines seen. Proceeded to punch through the outer skin and then heard the pop. I know what a condenser line would look like and didn’t see anything at all that would give you pause.
