Oxygen First Stage and Connections
The oxygen first stage is the Dive Rite Model RG1208. The IP
(intermediate pressure) for the oxygen side must be set to 90 psi (6.2 Bar).
This is lower than the normal factory standard setting for the RG1208
used for most applications. Pressures above 90 psi (6.2 Bar) will cause
higher battery drain on the primary handset, and may prevent the Solenoid
from properly firing. The normal factory configuration consists of a LP
inflator for the manual oxygen addition valve, A feed to supply the
solenoid, a first stage over-pressure valve (OPV), and a submersible
pressure gauge. The LP hoses and SPG cover are color coded in GREEN
to indicate oxygen use. The Oxygen supply to the solenoid may be fitted
with an optional cutoff valve.
Warning!!
The OPV located on the oxygen first stage should never be removed.
This is a important piece of safety equipment should the HP seat of
the first stage fail. The LP hoses can not withstand the high pressures
as supplied from the cylinder. This will cause a hose rupture and
possible injury.
