Bleeding instructions...

1. If you have the Serial U pipe... install it on the TOP port.
2. REMOVE ALL ACRYLIC INSERTS INCLUDING STOCK... Sorry to say this Tim, but its unfunctional, and only makes things worse.
3. Connect both side res's by removing side plug.
4. Make sure u have both top fill ports open and start filling.
5. Once u filled as much as possible.. close the right side, and then turn your pumps on.

Whats going to happen is the right side will purge.
The bubbles will go all over the place and eventually collect on the left side.
Since your left side fill port is open, you should be topping off, as the left side starts going down to 3/4th full.
You want to only leave a little air gap like in my pictures on the left side:


Then just keep topping the left side.... 10min later:


Another 10 min later :



This is the easiest solution i can think of, without adding a Tline.

Martin do me a favor please, and try to repeat this.
Confirm if its the easiest to bleed.
