1. GENERAL PRECAUTION & WARNINGS
•Be ore using this regulator, you must have success ully received training and
certi ication in the technique o SCUBA diving rom a recognized certi ication
agency. Use o SCUBA equipment by uncerti ied, or untrained persons, is dan-
gerous and can result in serious injury, or death.
•This regulator is not con igured or commercial use with sur ace supplied air.
•Always pressurize the regulator gradually by opening the cylinder valve
SLOWLY.
•NEVER lubricate any part o the regulator (particularly the O-ring providing
the seal between the cylinder valve and the regulator) with any lubricant.
•DO NOT apply any type o aerosol spray on the regulator. Doing so may
cause permanent damage to certain plastic components.
•The user should not undertake any assembly, disassembly or adjustment
other than those prescribed.
WARNING :
• DO NOT attempt to disconnect the second stage rom the hose while the
regulator is pressurized.
• DO NOT per orm any disassembly while the regulator is under pressure. Any
disassembly, including removing the second stage rom the hose should only be
per ormed by an authorized Aqua Lung Dealer.
• DO NOT pressurize the regulator with the second stage disconnected rom
the hose.
•Factory prescribed service or this regulator must be per ormed at least
once annually by a actory trained Aqua Lung Service Technician who is
employed by an Authorized Aqua Lung Dealer.
•DO NOT use the regulator irst stage as a carrying handle when li ting or
transporting the cylinder as this can damage the regulator or the cylinder
valve.
•When diving in cold water (below 50°F, or 10°C), you must have received
training and certi ication in the techniques o cold water diving rom a recogni-
zed training agency.
•I you are using a irst stage in the Legend series, you are recommended to
use a compensated Octopus (LX Octopus, Legend Octopus, Kronos Octopus,
Mikron Octopus) to avoid the possibility o a ree low at depth.

1.2 ENRICHED AIR NITROX USE
DANGER : This chapter contains important in ormation concerning use with oxy-
gen-enriched air (Nitrox/EAN). Do not attempt to use this product with enriched
air without having entirely read and understood this chapter. I you do not do this,
you risk serious accident or death.
DANGER : Obtain Nitrox Diving Certi ication
In order to gain a complete appreciation o the advantages o diving with Nitrox,
it is ABSOLUTELY NECESSARY that you undergo special training and obtain cer-
ti ication in Nitrox diving rom a recognised training agency. The depth and time
limit o the dive depend on the oxygen content o the Nitrox mixture.
5Back to the contents

1.2.1 Enriched Air Nitrox Use
Your Aqua Lung regulator has been prepared or use with Enriched Air Nitrox
(EAN) where the percentage o oxygen in the EAN does not exceed 40%. This is
possible because each regulator is built to a high standard o cleanliness using
EAN compatible components and lubricants. In addition, each regulator design
has passed stringent adiabatic compression testing to ensure its sa ety and
compatibility with increased percentages o oxygen.
I it is your intention to use your new Aqua Lung regulator with Nitrox EAN (O2
not to exceed 40%), it is imperative that you maintain the internal cleanliness o
the regulator (see section on Care and Maintenance). I it is your intent to use
the regulator interchangeably with breathing air, the breathing air should be
oxygen-compatible or “hyper iltered” whereas the condensed hydrocarbons do
not exceed 0.1 mg/m3. Your local authorized Aqua Lung dealer can help you
determine whether the breathing air that they provide meets this criterion.
Standard compressed breathing air meeting the EN 12021 standard, o ten
re erred to as Grade E in the United States, does not necessarily meet this cri-
terion. Grade E or EN 12021 breathing air may contain a certain level o hydro-
carbons, including traces o compressor oils that while not considered harm ul
to breathe, can pose a risk in the presence o elevated oxygen content. Passing
hydrocarbons through a valve and regulator creates a cumulative e ect where
the hydrocarbons build up over time along the internal passageways o the
equipment. When these hydrocarbons come in contact with high-pressure oxy-
gen enriched air, they can pose a very real hazard that can lead to combustion.
There ore, i a regulator has had use with Grade E or EN 12021 breathing air,
it should be returned to an authorized Aqualung dealer or overhaul service
including hydrocarbon cleaning, prior to being put back into nitrox service.
Although second stage components are not exposed to high pressure EAN,
Aqua Lung recommends that the same cleaning procedures be ollowed or the
complete regulator. This prevents the possibility o cross contamination and
guarantees the cleanliness o the entire regulator.

1.2.2 Nitrox use for CEE (European Community) countries
EN-144-3 and EN 13949
In CEE countries, diving with Nitrox/O2 is controlled by Standards EN 144-3 –
Respiratory protective devices - Gas cylinder valves - Part 3: Outlet connections
or diving gases Nitrox and oxygen - and EN 13949 – Respiratory equipment -
Open-circuit sel -contained diving apparatus or use with compressed Nitrox
and oxygen - Requirements, testing, marking.
NOTE : The maximum depth o the dive is determined by the type
o mixture used.
NOTE : Aqua Lung o ers a range o regulators designed and manu actured spe-
cially or use with oxygen-enriched mixtures, over 21% and up to 100% oxygen.
This range has been certi ied according to the EN 144-3 and EN 13949 stan-
dards and meets the requirements o the adiabatic compression tests. They
have received CE certi ication or this type. For urther in ormation on this range,
contact your Aqua Lung specialist centre.
DANGER : These regulators itted with special connections should be used only
with complementary equipment (tank valves, tanks, pressure gauges, etc.) des-
igned and prepared or use with an oxygen-enriched mixture. These items are
marked Nitrox/O2.
DANGER : I the regulator that you use is itted with a yoke or DIN connection, it
is designed or use only with compressed breathing air (21% oxygen and 79%
nitrogen) which meets the EN 12021 standard. DO NOT USE this equipment
with other mixtures or with gases containing more than 21% oxygen.
Disregarding this rule could result in serious accident or death caused by ire or
by an explosion.
Every Nitrox/O2 regulator is assembled in a clean workshop, using compatible
components and special lubricants.
It is important to maintain the interior o the regulator in a clean state (see
chapter 6 Regular Care). Breathing air used in the production o a mixture
should be oxygen compatible and double iltered with a hydrocarbon content
not greater than 0.1 mg/m3. Your Aqua Lung technical specialist should be
able to help you determine i the breathing air he supplies meets these criteria.

2.3 VANE ADJUST ENT SWITCH (VAS)
Most o our second stages are itted with a Vane Adjustment Switch (VAS).
The VAS can be ound in one o two di erent locations depending upon which
model you have. It can be located on the side opposite the hose connection OR
it can be ound on top in ront o the mouthpiece. It helps to maintain a high
low o air once you have started to take a breath.
When the VAS is set to the “MAX” (or “+”) position, the regulator will provide
maximum venturi assistance.
When the VAS is set to the “MIN” (or “-”) position, breathing resistance is
increased.
You should put it on the “MIN” (or “-”) position whenever the regulator second
stage is out o your mouth.
You may put it on the “MAX” (or “+”) position whenever the mouthpiece is in
your mouth.

2.4 Valve Adjustment Knob (VAK)
2.4.1 LEGEND LX GLACIA Regulator
The VAK, located opposite o the hose connection on certain model second
stages, adjusts the e ort required to start the air low at the beginning o the
inhalation cycle. As it is turned “in” (clockwise), the ope-
ning e ort will increase. This will make the second stage
less sensitive to sudden changes in ambient pressure.
Turning the knob “out” (counter-clockwise) will decrease
the opening e ort to make breathing easier.
This adjustment is particularly use ul at deeper depths,
or in variable conditions that a ect the opening e ort o
the second stage, such as strong currents or while using a diver propulsion
vehicle (DPV). It will also allow compensation or a di erence in the hydrostatic
pressure and the centre o your lungs, such as when you are in a head-down
position. You can use the VAK to tune your regulator to maintain its peak per-
ormance throughout the course o your dive, or you can leave it set in its mid-
range position and dive with as you would any non-adjustable second stage.
2.4.2. Kronos Second Stage Adjustment: „Dual Cam‰.
The Dual Cam patented adjustment system combines both the VAS and the
VAK.
In the “+” position: the VAS is maximum and the VAK is
minimum (turned out). This gives optimum per ormance
(average: 1.2j/l according EN 250).
In the “-“ position: the VAS is minimum and the VAK is
maximum (turned in). This reduces per ormance to the
maximum allowed by EN 250 (average: 2.8j/l). This
o ers a very e ective pre-dive position.
2.4.3 ikron Regulator
The VAK, located opposite o the hose connection on certain model second stages,
adjusts the e ort required to start the air low at the beginning o the inhalation
cycle. As it is turned “in” (clockwise), the opening e ort will increase. This will make
the second stage less sensitive to sudden changes in
ambient pressure. Turning the knob “out” (counter-clock-
wise) will decrease the opening e ort to make breathing
easier. This adjustment is particularly use ul at deeper
depths, or in variable conditions that a ect the opening
e ort o the second stage, such as strong currents or
while using a diver propulsion vehicle (DPV). It will also allow
compensation or a di erence in the hydrostatic pressure and the centre o your
lungs, such as when you are in a head-down position. You can use the VAK to tune
your regulator to maintain its peak per ormance throughout the course o your
dive, or you can leave it set in its mid-range position and dive with as you would any
non-adjustable second stage.
When the VAK is completely unscrewed (counter-clockwise), the regulator will pro-
vide maximum per ormances. When the VAK is completely screwed (clockwise),
breathing resistance is increased.
10 Back to the contents

11 Back to the contents
NOTE: Since the Mikron does not have a VAS, it is necessary to screw the VAK
all the way in when it is out o your mouth. Failure to do so could result in a ree-
low situation should the regulator get bumped or the purge cover depressed.
2.4.4 LEGEND LX Regulator: aster Breathing System ( BS) adjustment
This patented adjustment system, called the Master Breathing System, simulta-
neously controls both the opening e ort, by changing
spring tension, as well as the venturi e ect.
In the MAX position: the venturi e ect is at its maximum
and the opening e ort required is minimum. This will pro-
vide the best breathing per ormance.
In the MIN position: the venturi e ect is at its minimum
and the valve opening e ort is at its maximum, this
reduces the sensitivity o the regulator: the depression required to initiate the valve
opening is also increased.
The MBS allows you to compensate or the di erence in hydrostatic pressure your
lungs and the second stage.
For example, when you are in a vertical head-down position, you will want to
decrease the regulator's sensitivity by turning in the MBS. On the other hand, when
you are in a head-up position you will want to increase the sensitivity by unscrewing
the MBS to obtain improved breathing com ort.
We recommend that you set the regulator on the MAX setting while you are brea-
thing rom it and set it on MIN when it is out o your mouth.
2.5 Titan Quick-Connect System (patented)
The Titan regulator is equipped with a quick- connect itting linking the hose to
the second stage o the regulator.
The presentation below illustrates the proper method or removing and repla-
cing the second stage.
This procedure allows you to quickly disconnect the second stage rom the
hose without tools.
This operation should only be carried out by an Authorized Aqua Lung Dealer as
part o the Service/Maintenance procedures
The Quick Connect hose doesn’t have the eatures o a Direct System hose (BC
In lator Hose) and will not stop the low o air out o the hose i the second
stage is removed while under pressure.
2.5.1 Titan Regulator with hose properly connected
The lug on the lock nut prevents the hose rom loosening.

IMPORTANT REMINDER:
Be ore attempting to remove the second stage rom the hose, con irm the
regulator is not pressurized and the irst stage is removed rom the cylinder.
Do not leave the irst stage connected to a cylinder valve i the second stage is
removed rom its hose.
It’s recommended to use the hose clip (pn 216047). The clip will allow the end
o the hose to be attached onto
the hose itsel or onto the D-ring
o the BC.
Attaching the hose onto itsel :
Attaching the hose onto a BC D-
ring:
2.5.2 Disassembly
To disconnect the hose, pull the lock away rom the nut
while at the same time loosening the nut. The double
action o the quick-connect itting will prevent the hose
rom accidentally disconnecting.
REMINDER: This operation must only be per ormed with
the regulator depressurized and in a clean environment.
I you attempt to loosen the hose while the regulator is
still under pressure, a large air leak will happen approxi-
mately 2 turns be ore the nut is completely unthreaded.
I this occurs, stop loosening the nut and close the cylin-
der valve. Wait until the leak stops be ore continuing.
Disconnect the irst stage rom the cylinder valve.
Final removal o the hose.
To avoid contamination, don’t leave the hose disconnec-
ted rom the second stage.
12 Back to the contents

NOTE : In order to prevent contamination when the second stage is disconnec-
ted rom the hose, it is recommended that you use the protection plug (pn
496281) to cap o the hose.
2.5.3 Reassembly
Con irm the hose is clean and the irst stage is not connected to a cylinder
valve.
Reconnect the hose by tightening
the nut onto the second stage until
it locks into place. While tighte-
ning, the nut will push the lock in
causing a clicking noise until it
locks into the inal position.
2.6 First Stage Environmental Protection series Titan,
Kronos, Legend „supreme‰
For diving in cold-water conditions, or commercial diving in contaminated water,
Aqua Lung o ers an environmental irst stage protection eature that seals the
ambient chamber rom the environment. This helps to prevent ice rom or-
ming and keeps contamination out o the main spring chamber.

3. PREPARATION AND SET UP
Aqua Lung America, Inc. recommends that you bring your regulator to your
Authorized Aqua Lung Dealer or the installation o any accessory items, including ins-
trumentation, LP quick disconnect hoses, and alternate air sources.
DANGER : Whatever the connector, when pressurizing your scuba system, be
sure to open the cylinder valve slowly to minimize the generation o heat. Failure
to do so, with enriched air nitrox (EAN) present, increases the risk o combus-
tion that can lead to serious injury or death.
WARNING : It is considered a sa e practice, especially when using EAN, to open
the cylinder valve slowly and let the irst stage pressurize slowly. Rapid pressuri-
zation causes adiabatic compression o the breathing gas, which generates heat
inside the irst stage. Heat, along with elevated percentages o oxygen and an
ignition source ( rom contamination) are the ingredients that can cause com-
bustion. This is why it is necessary to keep the interior o the regulator clean
and the raction o oxygen below 40% along with the slow opening o the valve.
3.1 ounting the First Stage Onto the Cylinder Valve
3.1.1 Yoke Connector
Partially loosen the yoke screw o the irst stage regula-
tor so that the dust cap can be removed rom the ilter
and air inlet.
With the cylinder valve acing away rom you, release a small amount o air rom
the cylinder by turning the handwheel counter-clockwise to open the valve only
slightly. When air is heard exiting, immediately close the valve. This will clear any
moisture or debris that may be inside the cylinder valve outlet opening.
Check the condition o the cylinder valve O-ring
Place the irst stage regulator over the cylinder valve so
that the inlet itting aligns with the O-ring o the cylinder
valve, and the LP hose o the primary second-stage will
be routed over the right shoulder. While holding the irst
stage in place, turn the yoke screw clockwise. Ensure
that the yoke screw mates into the small dimple on the
backside o the cylinder valve, and tighten inger-tight
only.
14 Back to the contents

3.1.2 DIN Connector or Pr EN 144-3 connector
• Remove the protector cap rom the cylinder valve.
• With the cylinder valve acing away rom you, release a
small amount o air rom 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 o the cylinder valve O-ring.
• Position the irst stage near the cylinder valve so that
the LP hose o the primary second-stage will be routed
over the right shoulder. Thread the irst 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. Care ully inspect all hoses at their ittings to ensure they are securely
connected into their respective ports on the irst stage. Inspect the length o
each hose to ensure that the hoses are not blistered, cut, or otherwise dama-
ged. I hose protectors are present, slide the protectors back to expose the
hose ittings, and inspect the hoses as described above.
2. Visually inspect both the irst and second stage regulators or any signs o
external damage.
3. Visually inspect the mouthpiece to ensure that there are no tears or splits.
4. Check that the needle o 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 rom the hose while the
regulator is pressurized.
• DO NOT per orm any disassembly while the regulator is under pressure. Any
disassembly, including removing the second stage rom the hose should only be
per ormed by an authorized Aqua Lung Dealer.
• DO NOT pressurize the regulator with the second stage disconnected rom
the hose.

3.3 Pressurising the regulator
CAUTION : Be ore pressurizing the regulator check the condition o the hoses
itted to the regulator.
1. I a submersible pressure gauge is itted check that its dial aces
away rom 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 rom any o the hoses or rom any other acces-
sories itted. NEVER DIVE with a regulator that shows any leaks when placed
under pressure. I there is a leak between the regulator and the cylinder check
that the regulator is correctly itted and that the O-ring is in good condition.
WARNING : Never attempt to reposition the hoses once the regulator is under
pressure. I they are not correctly oriented, Close the cylinder valve, purge the
regulator and reposition them.
WARNING:
• DO NOT attempt to disconnect the second stage rom the hose while the
regulator is pressurized.
• DO NOT per orm any disassembly while the regulator is under pressure. Any
disassembly, including removing the second stage rom the hose should only be
per ormed by an authorized Aqua Lung Dealer.
• DO NOT pressurize the regulator with the second stage disconnected rom
the hose.
4. Check to ensure that the submersible pressure gauge is displaying an accu-
rate measurement o the air pressure inside the cylinder at the time o charging
and is appropriate or your planned dive.
5. Depress the purge button momentarily to ensure that su icient air low 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 "+", or
the Mikron and the Legend LX, completely unscrew the sensitivity adjustment
button (anti-clockwise).
7. Inhale slowly and deeply rom the regulator several times. The regulator must
deliver enough air or you to breathe easily without noticeable resistance.
16 Back to the contents

3.4 - Divisible mouthpiece
The Mikron or the lady is equipped with a speci ic mouthpiece. It will per-
ectly it the small jaw. The silicone bridge is in contact with the roo o the
mouth, i it is uncom ortable you have the opportunity to cut this bridge.
Using a pair o scissors or a cutter you can cut the bridge. Just cut where
the urrow lines are.
17 Back to the contents

4. DIVING WITH THE REGULATOR
I the regulator is used as a secondary breathing system (octopus), it is recom-
mended that you use a mouth piece plug to prevent the entry o any objects
and that you set the Venturi knob to position "-", or the Mikron and the Legend
LX, screw the sensitivity adjustment button completely in (clockwise).
Under water the second stage may start to ree- low when it is not in the
diver's mouth. I this occurs, turn the regulator so that the mouthpiece aces
downward.
When you replace the mouthpiece in your mouth, set the button to the "+" posi-
tion so that you obtain improved breathing com ort. For the Mikron and the
Legend LX, completely unscrew the sensitivity adjustment button (anti-clock-
wise).
Check your air supply at regular intervals by veri ying your cylinder pressure.
4.1. COLD WATER DIVING :
In order to reduce the risks o regulator reezing when diving in cold water
(below 50°F or 10°C), consider at least the ollowing recommendations and
respect your dive training program procedure :
1. Protect your regulator rom any accidental entrance o water into the irst
or second stages.
2. Protect your equipment rom cold be ore the dive. More precisely, keep your
regulator and all its accessories in a warm dry place.
3. Carry out all pre-dive checks o your equipment in a warm dry place, be ore
even going to the dive site.
4. Avoid breathing through the regulator or pressing the purge button in very
cold air be ore entering the water.
5. Avoid removing the regulator rom your mouth during the dive, or when on
the sur ace. This will prevent cold water rom entering the regulator second
stage.
6. As ar as is possible, avoid excessive e ort during the dive.
7. Have your dive store check that the air in your cylinder meets EN 12021
and is is dry.
8. As ar as is possible, do not purge the second stage during the dive.

5. AFTER THE DIVE
5.1 Removal of the Regulator from the Cylinder Valve
NOTE : I resh water is available, rinse your regulator completely be ore depres-
surizing it. This will help to prevent any contaminants rom entering sealing sur-
aces inside the regulator.
NOTE : When you remove the regulator rom the cylinder take care to prevent
the entry o water into the regulator, particularly via the ilter.
5.1.1 General Procedures
1. Shut o the cylinder air supply by turning the cylinder valve handwheel clock-
wise until it stops.
2. While observing the submersible pressure gauge, depress the purge button
o the second-stage. When the gauge reads zero and air low can no longer be
heard rom the second stage, release the purge button.
5.1.2 Yoke Connector
1. Turn the yoke screw counter-clockwise to loosen and remove the irst stage
rom the cylinder valve.
2. Dry the dust cap with a towel or other lint- ree cloth. While you may use air
rom your tank valve to blow the water o the dust cap, you run the risk o blo-
wing water into the ilter.
3. Place the dust cap over the irst stage inlet itting and seal it securely in
place by tightening down the yoke screw.
5.1.3 DIN Connector
1. Turn the DIN handwheel counter-clockwise to loosen and remove the irst
stage ro the cylinder.
2. With the cylinder valve acing away rom you, open the valve slightly to
release a short burst o air, and then immediately close the valve. This will clear
any moisture that may have entered the valve opening. Immediately seal the
protector cap securely in place over the opening o the DIN valve to prevent the
entrance o moisture or debris.
5.2 Cleaning
Aqua Lung recommend disin ecting the regulator second stage with a 2% solu-
tion o glutaraldehyde produced by the Anios company (Sterianos, Aqua Lung
re erence 382062) ollowing the procedure described on the package.

6. USER CARE & AINTENANCE
It is important to provide the proper preventative maintenance in order to
ensure the best possible per ormance and maximum li e o your Aqua Lung
Regulator. The ollowing maintenance procedures should be per ormed routi-
nely a ter each use to ensure that the regulator is cleaned, inspected, and pre-
pared or the next use or or storage.
As soon as possible a ter diving, the regulator should be rinsed thoroughly with
resh water while it is attached to a cylinder and pressurized with air.
Rinsing alone, however, will not su iciently clean the regulator. To clean the
regulator as thoroughly as possible Aqua Lung recommends:
. Attach the regulator to a charged SCUBA cylinder, open the cylinder valve to
pressurize the regulator, and thoroughly soak both the irst and second-stages
in a bath o resh water.
. While the regulator is soaking, move the vane adjustment switch on the
second stage (i present) back and orth several times rom the “MIN” (or “—”)
to the “MAX” (or “+”) settings. You may also turn the valve adjustment knob
(adjustable models) slightly back and orth—no more than 1/4 turn.
A ter the regulator has been properly soaked, it is important to rinse it vigo-
rously by lushing the mainspring cavity o the irst stage regulator (non-environ-
mentally sealed models only), the second-stage mouthpiece, and the openings
in the second-stage ront cover with a pressurized stream o water. This will
remove the deposits o salt and minerals that were loosened during soaking.
DANGER : i you use a garden hose, do not use the high pressure jet as this
could damage the diaphragm and the internal valve.
WARNING : DO NOT depress the purge button, loosen the irst stage yoke
screw, or turn the second stage adjustment knob all the way “out” (adjustable
models) i the regulator is submerged unpressurized. Doing so will allow the
entrance o moisture, and will require that the regulator be returned to an
Authorized Aqua Lung Dealer or service.
