EK 250 Adv Res Mounting

[(sic)]

Quick question for ya.

I have my res mounted upside down and want to know if that will cause a problem. I don't see how it could, but because EK specifically labeled a top and a bottom I wanted to make sure before I start the filling process.

Quick paint sketch to make my question more clear:

Also here the installation guide from EK.

The only thing I can think of would be making it a little harder to bleed?
I have the same res mounted inside the top of my case, and filled it while rotating in all directions but still was bleeding almost invisible air for a week... But it's no biggie, just check frequently and top up as needed.
