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.

USING SYNCHRO SERIES
REGULATORS
BEFORE EACH DIVE
The regulator must always be transported
separately so as to prevent it from being in
contact with the other components of
equipment or with heavy or pointed ob-
jects.
To assemble the regulator properly onto the
cylinder valve, proceed as follows:
When assembling a first stage with YOKE
connection, check that the O-Ring embed-
ded in the valve is clean, in good condition
and correctly fitted ; in case of THREAD
connection, the O-ring is housed in the
first stage.
The O-ring must be in perfect condition,
free from cuts or porosity; it is advisable to
have some spare available, so that it may
be replaced immediately once any signs of
damage are detected.
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.

Check that all the hoses are properly con-
nected to the first stage and that they have
no apparent signs of wear or damage.
Open the valve, let out a small quantity of
compressed air, thus clearing the any for-
eign matter from the nozzle.
Remove the filter protection cap inserted
on the relevant connections.
Check for filter integrity and proper cleaning.
Position the first stage on the valve and
start screwing it up using the knob, in case
of yoke connection, or the swivel screw, in
case of thread connection.
Slowly open the cylinder valve counter-
clockwise taking care to avoid violent and
sudden airflow through the regulator; at
the same time, it is recommended to let
out a breath of air from the second stage
by keeping the latter slightly depressed
warning!
do not carry out this operation if ambient
temperature is lower than +10°C.
