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.

Airsource Owner's Manual

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).

Figure 6bFigure 6a 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.

Operation of the Cut-off valve

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.
