To make it easy, I copied this from the rEvo page where it was hidden.



Blue hose to valve is onboard diluent coming FROM the cylinder to the manifold, able to be shut off with the valve.

Blue hose in middle returns diluent to the rig.

Black hose on left feeds BOV feed line (has CEJN on other end at BOV).

Inlet thru Swagelok non-return valve accepts any CEJN input (offboard gas bottle). Means that offboard gas can be fed from any bottle with the same hose that is used on a Viking Suit or Unisuit. Note that my drysuit inflator hose lays about 6 inches away from this inlet, and could be connected to it, or the offboard feed connected to my drysuit if needed.

Whatever diluent is selected as rig gas also feeds the BOV.

Onboard gas always feeds the drysuit (normal use).

Green 02 line feeds the wings / breathing inflator (wing inflate hose is on right side)

In abnormal conditions, either the diluent feed line or the 02 feed line can feed either BOV or the inflator... (redundant open circuit access to the gas)

Drysuit line can also feed the BOV or the inflator..... BOV has an articulating swivel that can feed at a 90 degree angle down, so the drysuit hose can be led directly to it, as can the feed hose from the offboard cylinder.

*Lots* of flexibility, but in normal use VERY simple. Leave the black valve closed. Internal bottle feeds drysuit. Offboard feeds BOV and ADV. Onboard 02 feeds wings (never inflated unless drysuit fails). Shut off (or disconnect) the offboard bottle, open the black valve, and onboard diluent feeds BOV and ADV. VERY simple and EVERYTHING can feed ANYTHING in an emergency. Offboard cylinder also has second stage (naturally).


The manifold with the QD and valve hangs trapped under my chest-strap on my harness. Makes it easy to access, simple to work with, and can be "unstuffed" and held out towards a buddy if needed. Actually, to be precise, the manifold is tie-wrapped to the left handset of the rEvo. The cross-chest strap goes over the *handset* cable/hose, and the manifold lays *on top* of the cross chest strap. I'll shoot photos of that later. It's a small detail.
