3.3 Pressurising the regulator
CAUTION
: Before pressurizing the regulator check the condition of the hoses
fitted to the regulator.
1.
If a submersible pressure gauge is fitted check that its dial faces
away from you.
2.
SLOWLY open the cylinder valve to pressurize the regulator. When the valve
is completely open, screw it back a quarter turn.
3.
Check that there are no leaks from any of the hoses or from any other acces-
sories fitted. NEVER DIVE with a regulator that shows any leaks when placed
under pressure. If there is a leak between the regulator and the cylinder check
that the regulator is correctly fitted and that the O-ring is in good condition.
WARNING
: Never attempt to reposition the hoses once the regulator is under
pressure. If they are not correctly oriented, Close the cylinder valve, purge the
regulator and reposition them.
WARNING
:
• DO NOT attempt to disconnect the second stage from the hose while the
regulator is pressurized.
• DO NOT perform any disassembly while the regulator is under pressure. Any
disassembly, including removing the second stage from the hose should only be
performed by an authorized Aqua Lung Dealer.
• DO NOT pressurize the regulator with the second stage disconnected from
the hose.
4.
Check to ensure that the submersible pressure gauge is displaying an accu-
rate measurement of the air pressure inside the cylinder at the time of charging
and is appropriate for your planned dive.
5.
Depress the purge button momentarily to ensure that sufficient airflow is pro-
vided to blow out any dust or debris which may have entered the second-stage.
6.
Place the regulator in your mouth and set the Venturi knob to position "+", for
the Mikron and the Legend LX, completely unscrew the sensitivity adjustment
button (anti-clockwise).
7.
Inhale slowly and deeply from the regulator several times. The regulator must
deliver enough air for you to breathe easily without noticeable resistance.
