A while ago I took my wife to a bed and breakfast on a lake. It was an older place, but how they (mis-)treated one of the ice machines — which itself appeared to be pretty old — was something else.
It was one of those models that produces 400 pounds of ice per day. But if it ever came close to 400 pounds it would be a miracle. It was shoved into what looked like a small closet in an outdoor locale. There may have been an inch of clearance on either side. The unit was set on a couple of 1x2 pieces of wood resting on a concrete floor. There was a venting area on the backside of the closet, but the filter in the vent area was quite dusty.
