3.1.2 DIN Connector or Pr EN 144-3 connector

• Remove the protector cap from the cylinder valve.

• With the cylinder valve facing away from you, release a

small amount of air from the cylinder by turning the

handwheel counter-clockwise to open the valve slightly.

When air is heard exiting, immediately close the valve.

This will clear any moisture or debris that may be inside

the threaded cylinder valve opening.

• Check the condition of the cylinder valve O-ring.

• Position the first stage near the cylinder valve so that

the LP hose of the primary second-stage will be routed

over the right shoulder. Thread the first stage DIN

connector into the cylinder valve and turn the handwheel

clockwise by hand until it is lightly snug. DO NOT use

tools to tighten.

3.2 Pre-Dive Checks

1.

Carefully inspect all hoses at their fittings to ensure they are securely

connected into their respective ports on the first stage. Inspect the length of

each hose to ensure that the hoses are not blistered, cut, or otherwise dama-

ged. If hose protectors are present, slide the protectors back to expose the

hose fittings, and inspect the hoses as described above.
2.

Visually inspect both the first and second stage regulators for any signs of

external damage.
3.

Visually inspect the mouthpiece to ensure that there are no tears or splits.

4.

Check that the needle of your submersible pressure gauge is on zero.

5.

Check that the Venturi adjustment or the Dual Cam is set on -- .

For the Legend LX, check that the Master Breathing System is screwed com-

pletely in (see chapter 2.4.1).

For the Mikron, check that the sensitivity adjustment button System is screwed

completely in (see chapter 2.4.3).
6.

Fit your regulator to the cylinder (see Chapter 3.1), checking that the hoses

are oriented correctly.

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.
