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.
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

warning!
do not carry out this operation if ambient
temperature is lower than +10°C.
Depress two or three times the purge but-
ton of the second stage to discharge dust
or foreign matter. Finally, breathe from
the second stage to make sure that every-
thing functions correctly.
warning!
Do not carry out this operation if ambient
temperature is lower than +10°C.
Check the cylinder internal pressure by
means of the appropriate pressure gauge.
In order to optimize the positioning of the
different valves, it is recommended to
place the main and secondary regulators
on the right hand side and the service
valves (pressure gauge hose, jacket hose,
and dry diving suit hose) on the left.
The valve must be fully open before start-
ing diving.
When the regulator is not held in your
mouth at the time of entering into the wa-
ter, it is advisable to submerge it com-
pletely to prevent air discharge due to its
high sensitivity.
The Octopus or the second safety regula-
tor should be used in PRE-DIVE position
and with the appropriate cap fitted on the
mouthpiece to prevent the entrance of
foreign matters or accidental air delivery.
Warning!
Do not rotate the first stage connection
with the cylinder at any time with the sys-
tem under pressure.
