Technical Specifications - Seac Sub N-Synchro Instructions

FIG. 7
N-SYNCHRO OCTO.
The technical characteristics and materials used
in the N-SYNChro oCTo are the same as
those used for the second stage version as-
sembled with the N-SYNChro first stage de-
scribed above.
The only differences are the color of the shield,
which is green to make it easier to identify in a
hurry, and the color of the hose, which is yel-
low. The latter is especially made with a length
of 1000 mm (3/8" thread) for easier use in an
emergency.
We recommend positioning the N-SYNChro
oCTo to PrE-DIVE when it is used as an auxil-
iary or emergency regulator.
A certified technician only must mount the
N-SYNChro oCTo to the first stage in order
to ensure the functionality and safety require-
ments needed.
Use a common 4-mm Allen wrench to remove
the low pressure port closing cap (3/8" thread).
Then make sure that the o-ring is present,

inserted and positioned in the hose over the
relevant thread. Screw up the hose with your
fingers until the end stop is met, and then
tighten the nut with a 14-mm spanner without
using excessive force.
Check for proper operation by pressurizing
the assembled regulator from a tank before
the dive.
For safety reasons we recommend that you use
the N-SYNChro oCTo only and exclusively on
an N-SYNChro first stage with intermediate
pressures between 9.8 and 10.0 bar.
in order to keep the certification valid, we
recommend that you check that the n-sYn-
CHro oCto regulator is assembled in seac-
sub first stages that are expressly dedicated
and certified for use with nitrox mixtures.
Failure to observe this recommendation may
cause the second stage to function improp-
erly and cause serious accidents.
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 pressure
components were designed and implemented
to operate with pressures not exceeding 20 bar.
Failure to comply with this warning may cause
serious damage to persons and equipment.
Always be extremely careful when handling
components under pressure.
