Got it. I was under the impression that "top off" is overflowing. So what I understand, it really means "nearly full".
How do I know if I bled the loop properly already though? With the H220X, the tubes are not transparent so I don't see air packets visually.
Ok, got it.
So in order to remove all air from the loop, do you need to fill the reservoir until it overflows to the opening of the fill port itself? Or in my case with the H220X,should I only fill up to the Max level?
I'm beginning to see the light of the end of the tunnel regarding my question. I just have a couple of questions though:
1.) Why do air get trapped in high spots? Is it the same principle as "hot air naturally rises"?
2.) When air is already in the res, why does it stay/get trapped there?
