Looking for USD Sea4 Service Manual

[caileon]

Hello,
I am an Aqua Lung service tech and recently came across a USD Sea4 2nd stage and would like to service it. I would like to read the exact manula for this 2nd stage regulator before I begin. Does anyone have it on PDF form or know where I can get it. I believe it came out in 2005 or 2006.

Thanks

The main difference in the Sea series is the first stage. The second stage of an SEA 4 is similar to an SE3, Conshelf 22, latter Aquarius models and some other models. Any of those manuals or even some of the earlier ones should give you a good idea on what to do. Frogkick.Dk is usually the go-to source for manuals but I don't see any for these second stages.

The Aqualung parts manual pdf on Frogkick has a good schematic of the SEA 4.
