OXYGEN ALERT!
Slow opening of the cylinder valve is the best way to protect the
system from compression shocks. Rapid openings represents the
highest risk for fire due to compression shock. To ensure a slow
opening it is good practice to use both hands, one on top of the other.
Always open the cylinder, and
isolator valves if used, first fully and
then a 1⁄2 turn back.
Partly opened valves increases the
pressure drop over the valve and can
reduce the performance. On some
brands, valves that are almost closed
can even shut off during a dive due
to internal flexing of materials.
5. Press a few times on the purge
button on the second stage so as to
blow out possible debris.
6. Check the pressure gauge to see that
the tank is full, whilst purging, by
watching the almost zero deflection
of the needle this indicates that the
air is flowing correctly with no
restrictions.
7. Test breathe through the regulator
and the octopus. If the gas smells or
tastes bad do not dive with it.
Tip! You can test the regulator’s correct setting by partly immersing the 2nd
stage in water, see picture. The servo valve should crack open when the
regulator is immersed in between the two positions shown.
Tip! At dives where the water conditions are very cold or there is an apparent
risk for hypothermia, i.e. at Trimix dives or water temperatures < 10ºC (50ºF), it
is recommended to use the surgical cord around the neck for the regulator
being used. The mouth region can become numb from cold and you risk
loosing the regulator.
