i have downloaded the technical manual for the novotronic (H350, H373, H387) ovens. No detailed instructions there on how to install the ovens. For example no instructions on how to install two trim pieces to protect oven electronics from spills when installed under a counter, instead of in a wall cabinet. i figured out the top one, second one won't work. it looks like the holes are in the wrong place. I think that is unlikely.
