BEFORE EACH DIVE
The regulator must always be transported
separately so as to prevent it from being in
contact with the other components of the
equipment or with other heavy or pointed
objects.
To assemble the regulator properly onto the
valves, proceed as follows:
When assembling a first stage with YOKE
connection, check the O-Ring embedded
in the valve; in case of THREAD connec-
tion, 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 ones, so that it may be re-
placed at once in case the above signs of
damage are detected.
Check that all the hoses are properly con-
nected to the first stage and that they do
not show apparent signs of wear or damage.
Open the valve let out a small quantity of
compressed air, thus clearing the nozzle
from any foreign matter.
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 air flow 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
do not carry out this operation if ambient
temperature is lower than +10°C.
Depress twice or three times the purge
button of the second stage to discharge
dust or foreign matter. Finally, breathe
from the second stage to make sure that
everything works properly.
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 pla-
ce 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.

warning!
warning!
The valve must be fully open before dive
start.
When the regulator is not held in your
mouth at the time of plunging into the
water, 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 fo-
reign matters or accidental air delivery.
Warning!
Do not rotate the first stage connected
with the cylinder with the system under
pressure.
DURING THE DIVE
When the regulator is not held in your
mouth, air self-delivery may occur. This in-
convenience may be easily eliminated by
rotating the regulator upside down while
checking that the same has been previou-
sly filled with water.
The use of suitable containers for mouth-
piece protection will prevent such inconve-
nience and will also provide a cover for the
passage inside the second stage, thus re-
moving the risks of sand and dirt introduc-
tion into it.
Check that the regulations placed on the
Diamond second stage are set in such a
way as to fully exploit the advantages pro-
vided.
AFTER EACH DIVE
AND PERIODIC MAINTENANCE
Your regulator is made of very high-quality
materials and has undergone exhaustive sea-
water testing. However, every precaution
shall be taken in order to protect the equip-
ment from the corrosive action of salt.
Below is the procedure to be followed after
surfacing or on board at the end of the dive.
The first operation to be carried out after the
dive is to disassemble the equipment used.
Close the valve by turning it clockwise; di-
scharge all the residual air remaining in
the regulator system by actuating the se-
cond stage pushbutton.
This operation may require several se-
conds, as the air leaving the pressure gau-
