DIAMOND OCTO
The technical specifications and the materials
used for the DIAMOND OCTO are the same as
for the second stage version assembled on
the above described DIAMOND and DIA-
MOND ICE regulators.
The only differences are in the color of the
shield which is yellow, especially designed for
easier identification in case of quick use, and in
the hose which is also yellow. The latter was es-
pecially made with a length of 1000 mm (3/8"
thread) for easier use in emergency conditions.
We recommend correct positioning of the DI-
AMOND OCTO to PRE-DIVE and with the air
flow regulation knob fully screwed up if it is
used as an auxiliary or emergency regulator.
The DIAMOND OCTO first stage assembly
shall be carried out by qualified or experi-
enced persons in order to optimize and en-
sure the functionality and safety require-
ments needed.
Use a common 4 mm Allen wrench to remove
the low pressure port closing cap (3/8" pitch)
then make sure that the O-ring is present, in-
serted and positioned in the hose over the rel-
evant thread. Screw up the hose with your fin-
gers until end stop, and then tighten the nut
with a 14 wrench without using excessive force.
Check for proper operation by putting the as-
sembled regulator under pressure before the
dive.

For safety reasons you are recommended to
use the DIAMOND OCTO only on the DIA-
MOND, DIAMOND ICE and SORIUS first stages
having an intermediate pressure of 9.8 bar.
The use of the DIAMOND OCTO connected to
other first stages automatically makes the CE
Certification null and void, as the latter was
obtained with tests carried out with connec-
tion of the DIAMOND OCTO to Seac Diving
Pro First stages.
Failure to comply with this recommendation
may also cause malfunctioning of the second
stage and serious accidents may result.
Do not use adapters for any reason with the
purpose of connecting the low pressure hose
and relevant second stage to the high pres-
sure port identified by letters HP. Low pres-
sure components were designed and imple-
mented to operate with pressures not
exceeding 20 bar. Failure to comply with this
warning may cause serious damage to per-
sons and equipment.
Be extremely careful when handling compo-
nents that are under pressure.
