If you have any questions regarding this
Airsource or these instructions,
contact your Aqua Lung®retailer.
Further, scuba diving requires specic techniques to avoid serious injury. DO
NOT attempt to use this equipment, even in shallow water, until you have
received certied scuba instruction from a recognized agency. This includes
verication of your ability to master the proper procedures for dealing with an
out-of-air emergency. If you are in doubt as to what this means, contact your
local professional scuba retailer for clarication.
WARNING: Improper use of this Airsource could result in
serious injury or death. DO NOT attempt to use this regu-
lator until you have completely read, understood, and fol-
lowed all instructions and safety precautions in this owner’s
manual. Be certain to understand the following guidelines
and limitations.

INTRODUCTION
Congratulations on selecting the Airsource. This unit is the combined product
of many years of research, engineering and eld experience. The very latest in
materials and technologies have been used in the design and manufacturing of
the Airsource. All materials and components are laboratory and eld tested for
reliability and long life.
What is the Airsource?
The Airsource combines the function of your ination device with an easy
breathing second stage regulator. The Airsource (Figure 1) thus replaces the
need for a backup second stage regulator (octopus). Combining the inator and
octopus into one integrated unit streamlines the diver and reduces bulk.
The Airsource is intended as a back up second stage for recreational scuba
diving only. Therefore, in order to protect you and your equipment, please
abide by the following guidelines and limitations.
SAFETY INFORMATION
Damage
Do not use an Airsource that shows visual signs of damage to the second stage
or its associated hose. If the second stage regulator presents an uncomfortable
resistance to breathing, or oods after clearing underwater, do not continue to
dive until the problem is resolved.
Figure 1
Lubrication
Do not use the Air Source if it has been lubricated with a hydrocarbon based
lubricant such as motor oil, light machine oil, or grease. Lubrication should be
performed only by qualied technicians and should only involve the use of lubri-
cants approved by Aqua Lung.

INSTALLATION
Aqua Lung recommends that you bring your Airsource, buoyancy compensa-
tor and regulator together to your authorized dealer for the installation of your
Airsource. The retailer can also answer any questions you may have pertaining
to the information in this manual. If it is not possible to return to your authorized
dealer, you may install the Airsource onto your BC and attach the MP inator
hose to your rst stage by carefully following the steps in the following proce-
dure.
Attaching Airsource to BC
To install, unscrew original inator assembly counterclockwise at the shoulder.
Place new Airsource assembly onto threaded portion, and screw clockwise
until tight. Make sure the o-ring gasket is in place and in good condition on the
threaded portion of the BC.
1. Detach the medium pressure (MP) inator hose
from the hose guides at the middle (Figure 2) and
top hose guides.
Figure 2
The Airsource is specically designed so that the lower unit can be easily
detached and stored with your regulator.
WARNING: DO NOT connect the inator hose to a high pressure
(HP) port (greater than 200 psi/14 bar). This may cause the hose
to burst when pressurized, which can result in serious injury. If
you are unsure which regulator port is medium pressure (MP) or
high pressure (HP), consult your regulator's owner's manual or
your dealer before attaching the hose.
WARNING: DO NOT attempt to remove the MP inator hose from
the Airsource body, as this may cause damage to the hose and/or
body. The Airsource is specically designed so that the MP ina-
tor hose remains attached to the unit.

2. While holding the molded hose steady just below the Trim Grip™ (Figure
3a), grasp and turn the Trim Grip™ 1/4 turn counterclockwise (Figure 3b).
Next, pull down on the molded hose to disengage the lower assembly
(Figure 3c).
3. Remove the port plug from a medium pres-
sure (MP) port on the regulator using an ap-
propriately sized wrench (Figure 4).
4. Check to ensure the hose o-ring is present
and in good condition, tighten the threaded
end of the hose into the port. Torque to 40
inch-pounds (4.5 Nm) with a 9/16" wrench
(Figure 5).
5. Secure buoyancy compensator to cylinder and attach rst stage regulator
to cylinder valve.
6. Check to ensure the connection o-ring on the lower assembly is present
and in good condition.

7. Hold the lower molded hose and Trim Grip steady, engage the Airsource
lower assembly by lining up the upper and lower connection points (Figure
6a) and carefully turning clockwise 1/4 turn (Figure 6b) until it snaps into
place (Figure 6c).

8. Slide the medium pressure (MP) hose into the upper (Figure 7) and middle
hose guides.

The Cut-off valve is a feature unique to the Airsource, which allows the air
supply to be turned off or on by pushing the device up or down. When the
Cut-off valve is pushed down (Figure 8a), air is supplied to the hose. To stop
the supply of air, simply push the Cut-off valve in an upward direction (see
Figure 8b). The Cut-off valve eliminates the need to detach the MP hose to
stop the air supply in the unlikely event of automatic ination; simply push
the valve up to stop the air supply.

BC Ination
Just as with a conventional inator, power (MP) or oral ination can be utilized
when using the Airsource. Both procedures need to be practiced to become
familiar.
Medium Pressure (MP) Power Ination
The power inator is a primary means for adding air to the otation cell. The
power ination system enables you to inate the BC simply by pressing the
small red ination button (Figure 9). With practice you will soon be able to
quickly make buoyancy adjustments without interrupting your diving activity.
