Question Apeks DS4

[Nudibranch Diver]

Hi - 2 questions if I may.

I'm trying to find a technical manual for the APEKS DS4, seems a little like find hens teeth at the moment. I really would like to see an 'exploded' diagram of the parts with index of part names and codes.

Regarding the intermediate pressure - I know it should be around 9/10 bar but mine is stable at 12 bar - is there a way of correcting this and if not, what is the issue with the increased pressure? I'm being told that its fine but would like to know how / why.

Sorry, I think that's 3 questions!

Re: manual, check your DM. Too large to send by DM alone.
Here's the Schematic.

Yes, spec is 9-10 bar, and no, 12 bar is not fine.
Your second stage is balanced, but only to to a point. At 12 bar, you are more likely to freeflow, depending upon how well your second stage is tuned to that IP.

Correcting it is a matter of 5 minutes on a bench.
See the manual.

Could you DM me the manual too? I got the parts list and the drawing, but miss the Service manual

Far too high and NOT fine at all.
