Pre-Dive Inspection - Aqua Lung Conshelf XIV User Manual

PRE-DIVE INSPECTION

1. Carefully inspect all hoses at their fittings to ensure they are securely connected
into their respective ports on the first stage. If hose protectors are present, slide
the protectors back to expose the hose fittings. Inspect the length of each hose
to ensure that the hoses are not blistered, cut or otherwise damaged.
2. Visually inspect both the first and second stage regulators (including the
octopus regulator) for any signs of external damage.
3. Visually inspect the mouthpiece on both second stage regulators (primary
and octopus). Check to ensure there are no tears or splits and it is securely
fastened to the second stage body.
4. Check that the needle on your submersible pressure gauge reads zero.
5. Attach your regulator to the cylinder valve, checking that the hoses are oriented
properly.
6. If a submersible pressure gauge is attached to the regulator, ensure that the
gauge dial faces away from you.
7. SLOWLY open the cylinder valve counter-clockwise to pressurize the regulator.
When the valve is completely open, turn it back one quarter turn clockwise.
NOTE: When properly maintained, the Conshelf XIV Supreme external diaphragm
should be slightly indented when unpressurized. Upon pressurization, the external
diaphragm will flex slightly outward.
8. Check that there are no audible leaks from any hoses or accessories attached
to the regulator. NEVER DIVE with a regulator that shows any signs of leakage
when placed under pressure. If there is a leak between the regulator and the
cylinder valve, check that the regulator is correctly attached and that the o-ring
is in good condition.
9. Check to ensure that the submersible pressure gauge is displaying an
accurate measurement of air pressure inside the cylinder and is appropriate
for your planned dive.
