That manual also says which direction to flush the lines.
The metal manifold which attaches to the compressor is supposed to be renewed because they think it can not be cleaned properly.
I really would not take a chance on guessing as to which fluid will clean properly and NOT deteriorate the insides of the AC lines... seems like an unnecessary chance to take.

thats weird, of all the lines I would have thought the metal manifold is the one that would clean the best..... Anyway, the manual is geared toward fixing in any situation. Maybe a million miler would need all new parts, but mine was working fine last year and only stopped because the PO's mechanic didnt mount the compressor right, breaking the bolts and eventuall it broke the seal and leaked freon. It was a pretty clean system, but even with that the flush cleaned out a lot of black oil. From what Ive read whatever I did wrong will show up in longevity losses so I am keeping my fingers crossed, it is really hot here.
