Been advised to fit an AAV on return of a sealed system to try and keep air out of the HEX as it keeps error coding about circulation. Power flushed the system already, this is the next step.
Anyway, usually fit AAV on positive side of pump so how far away from pump to make sure AAV does not suck air in?
