Can someone explain ventilation requirements for compressors? I will be placing mine at one end of a wide storage alcove next to the garage, so it will be covered and out of the snow. The installation instructions have pages of different configuration charts, but none exactly matches mine. What I see in my Daikin and other manufacturer manuals though is something I don’t understand. If you have 1 unit in a space like mine, it can be placed 4-10″ from the corner. But once you add a second unit next to it, the first one needs to start 40″ away from the corner. I can’t figure out why this would be. If they needed 40″ between them that would make more sense to me.
