nism adjust the Venturi effect. The lever, reg-
ulating the breathing effort reduction sys-
tem, control this system. By actuating this
mechanism placed to the left of the second
stage you can adjust the Venturi effect and
consequently increase air delivery.
By turning the lever towards the outside you
reach the "DIVE" position, and by turning the
lever towards the diver you reach the "PRE-
DIVE" position (Fig. 11).
The "PRE-DIVE" position is recommended to
prevent accidental delivery when the regula-
tor is under pressure but not in use, while the
"DIVE" position is recommended during the
dive.
Warning! Move the lever to "PRE-DIVE" only
when the regulator is not used, and rotate it
to "DIVE" before starting diving.

SYNCHRO OCTO.
The technical specifications and the materials
used for the SYNCHRO OCTO are the same as
for the second stage version assembled on
the above described D-SNCHRO, D-SYNCHRO
ICE and P-SYNCHRO regulators.
The only differences are in the color of the
shield, which is yellow, especially designed for
easy identification in case of quick use, and in
the hose, which is also yellow. The latter is es-
pecially made with a length of 1000 mm (3/8"
thread) for easier use in emergency condi-
tions.
We recommend correct positioning of the
SYNCHRO OCTO to PRE-DIVE and with the air
26
flow regulation knob fully screwed up if it is
used as an auxiliary or emergency regulator.
A certified technician shall only carry out as-
sembly of the SYCHRO OCTO first stage in or-
der to ensure the functionality and safety re-
quirements needed.
Use a common 4 mm Allen key to remove the
low pressure port closing cap (3/8" thread)
then make sure that the O-ring is present, in-
serted 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 with-
out using excessive force.
Check for proper operation by putting the as-
sembled regulator under pressure from a
cylinder before the dive.
Warning!
For safety reasons you are recommended to
use the SYNCHRO OCTO only on the D-SYN-
CHRO, D-SYNCHRO ICE and P-SYNCHRO first
stages having an intermediate pressure of
9.8/10,2 bar.
The use of the SYNCHRO 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 SYNCHRO OCTO to Seacsub S.p.A.
first stages.
Failure to comply with this recommendation
may also cause malfunctioning of the second
stage and serious accidents may result.
Warning!
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.
