Silly O2 feed question

edasque · 6th January 2009, 19:03

Hi all,

so I am getting a new NarkedAt90 cell checker soon and I have a dumb question. I need to connect the manual addition hose to the cell checker to fill it up with O2 at 1bar or whichever it is. It seems I would need to plug the O2 solenoid feed to do that and probably remove the hose then plug it at the first stage level. Any other idea ?

Find an old Deco or Pony Bottle and and old Reg, O2 clean them & dedicate them to the cell checker.

I haven't been diving for long enough or live in a big enough place to have old unused equipment lying around, Richie :)

Install an inline shutoff valve?

That's another good way to go.... I use one and it will allow you to hook up without connecting the canister.... and also give you a way to deal with a stuck open Solenoid situation without having to feather your tank valve.

Eric, if you can afford the cell checker, surely you can afford a 1st stage and QD hose. If not use one from your bailout.

My bailout reg is probably not 100% O2 clean, are the DR regs O2 clean by default ?

Also, I can't afford the cell checker, I am building something for use with them. Finally putting my electronic skills to good use.

Yes, all DR regs come O2 clean. If you have kept particulate matter out of them, they should still be that way. :)
