I'm sure that it's in the FI. Each ISA has an "A" system side and a "B" system side, applying press to the opposite side that is disconnected isn't dangerous, no more than walking down the sidewalk.

Instead of talking about T.O.'s try reading previous posts... The whole heat exchanger thing was already addressed. But thanks for adding your 6 years experience anyway... Evil or Very Mad

Jeez, man, if you wanted to scare the poor guy, you could've just pulled a gun on him... Every bubble chaser always does say the ISAs, and every techie / engineerie always says can't happen. We all know it does- Yer always servicin' up Bsys, always bleedin' off A. Where was the discourse on the heat exchanger? Went back through the pages, did a search, nothing but what we got here. In the TO it *does* look like that, but I'm guessing (hah! fer a xng) the internal plumbing doesn't mix...? Slap

I can remember back to 1981 and we had the cross bleed then.....just drain one and service the other.

I have done that job in the T.O. but it was for another problem, not the crossbleeding, too much air in one side the other side always stayed the same, so I am thinking accumulator, changed every stinking one, actually had them bench check because we didn't have any on base, bench checked good, reinstall, 4 days later run into the same issue, I swear to super that its the accumultor, that much air can't come from an ISA rod end, and sure enough on further inspection by hydro shop, it was a bad accumulator, problem fixed. I believe the fault tree that has you follow that is for Resevoir reading incorrect amount, not too sure though would have to look it up.

Here is another question though, will a return line actually suck air into the system if it is loose or cracked? I have heard many people on the line, say that it will but I usually just blow it off, as I have never seen it, seen plenty or return lines leak, cause its a pressurized system, but never just suck air into the system.

Cross-bleed from hydro B to A or vice versa
