You need epoxy that works at that temp. You can't use superglue to attach wood to plastic. It won't work.

In my case, since I had already figured out that there were no refrigerant lines in the side wall of the fridge, I attached a 1/4" strip of plywood with 3/4" SS screws to the plastic. Then just put some 1" SS screws in the plywood and hung the manifold from them. Its been there for three years, no issues.

Self tapping sheet metal screws work great
