Ventilation Requirements for Minisplit Condensers
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.

I don't have a specific answer for you but I can say that outdoor units need a LOT of airflow to operate properly so anything that could affect the free flow of air needs to be kept to a minimum. Maybe they have determined that the airflow needs of two units next to each other require most space around both units.
