I just received my 63 qt Edgestar, and need to come up with a way to mount it in my 80 series. I have a platform back there now, and have considered cutting out half of the platform and sitting the fridge inside, so it sits at floor level. This would however basically enclose it on 2 or 3 sides. How much air circulation room is needed around this unit? There is one air vent on the back side near the bottom, so obviously that needs to have space around it. Other than that though, what is necessary?
