Anyone know what the small cardboard pieces are that are inserted in the rear of the unit. Only noticed them today when one fell out.
The rear panel is one big heat sink, where did the cardboard come from? There certainly shouldn’t be bits of cardboard inside.
Hi, I had 2 in mine, small wooden wedges, look like they are to protect the 2 outer fins from damage. Quite a smart idea as the outer fins are most susceptible to getting a clout I imagine.

I assumed transit protectors and removed them on installation years ago?
