Oral Inflation

The oral inflator is a secondary means for adding air to the flotation cell. It may

be used when you are unable to, or do not wish to add air with the power inflator.

1. Before depressing the large grey oral inflation/deflation button, exhale a small

amount of air into the mouthpiece in order to purge any water that may be trapped.

this will reduce the amount of water that may be introduced into the bc.

2. After the water is purged and without removing the mouthpiece from your

mouth, immediately depress and hold down the large grey oral inflation/deflation

button and, with the same breath, continue to exhale into the mouthpiece.

Release the oral inflation button immediately after exhalation in order to stop

the release of air from the flotation cell.

3. Repeat this procedure until the proper buoyancy is achieved.

NOTE:

It is important to prevent sand and other debris from

entering the mouthpiece. these objects can contaminate the valve

mechanism and, under certain conditions, prevent it from closing

completely. if this should occur, operate the oral inflator several

times while shaking it underwater. if this action is not successful,

terminate the dive until the situation is remedied.

DEFLATION

Normal deflation of the BC should be accomplished by utilizing the Trim

Grip™, as well as dump valves. Please refer to your BC owner's manual

for model specific valve locations. Air can also be vented manually through

the mouthpiece by pressing the oral inflate/deflate button.

WARNING:

If during your pre-dive check, or at any time during

the dive you find that the Relief Valve will not fully close and

seal or will not fully open and vent air, DO NOT continue the

dive. Continuing the dive under these circumstances could

result in serious injury or death.

WARNING:

The Airsource does not come equipped with an over

pressure valve. it must be rigged to a BC that features an over

pressure valve. if you have questions regarding the features of

your bc, ask your local authorized Aqualung

Deflation by the Relief Valve

The Relief Valve provides the primary convenient means for exhausting air

from the BC. The valve opening located at the top of the BC must be above

the body when submerged for venting to occur. This is best achieved by

moving toward an upright position when venting air.

1. To activate, simply pull downward on either the Trim Grip™ or the Airsource

body. (Figure 10). This action transmits force through internal stainless steel

cables and opens the valve at the shoulder to allow air to vent from the BC.

2. Releasing the Trim Grip™/body closes the valve.

NOTE:

It is not necessary to exert an excessive downward pull to activate

the Relief Valve. When you pull on the Trim Grip™, you will feel the hose

stretch, allowing the exhaust valve to open. The travel of the valve is limited

to less than 1/4". Pulling harder will not increase the air flow. Maintain a

downward pull until the desired buoyancy is reached. It is not necessary to

raise your arm overhead when using the Relief Valve system.

Oral Deflation

The oral inflation/deflation valve is secondary means for venting air from the

BC. Most users vent air through the dump valves. However, you may find it

easier to expel the last portion of air remaining in a nearly empty BC by utiliz-

ing the oral inflation valve.

1. Move into an upright position so that you can hold the Airsource above the BC.

2. With the Airsource in the left hand, raise the assembly to a position nearest

the surface of the water.

3. Depress the oral inflation/deflation button allowing air to exhaust in small

increments until the desired buoyancy is achieved.

4. Release the button allowing the valve to close.

NOTE:

Do not hold the oral inflation/deflation button open after all

the air has been exhausted. Doing so may allow water to enter the

BC. Also, whenever inflating or deflating your BC, be sure to make

small but frequent adjustments. This will minimize the amount of

water entering the BC.

BACK UP SECOND STAGE REGULATOR

The Airsource is a high performance, pneumatically balanced second stage

regulator, and it operates the same as a standard second stage regulator.

To breathe, put the mouthpiece in your mouth. Purge the water by either

pressing the purge button, or exhaling slowly and continuously. You should

test the breathing performance of the Airsource before each dive.

WARNING:

Air situation should be reviewed before every dive. Make sure

your dive buddy is familiar with the operation of the Airsource

and what role it plays in an out-of-air situation.

In the event of an emergency air sharing situation, the assisting diver should

offer their primary second stage to the diver requesting to share air. The Air-

source then becomes the primary regulator for the assisting diver.

While using the Airsource as your second stage regulator, all inflation

and deflation procedures as outlined in this manual are still applicable.

Inflation

While breathing normally from the Airsource, push the power inflator button to

inflate the BC. For oral inflation, breathe in normally through the mouthpiece,

then depress the inflate/deflate button and breathe back out through the

mouthpiece. Release the oral inflation button immediately after exhalation in

order not to allow the air to escape from the air cell. Instead of the air escaping

through the exhaust valve, the air will be diverted into the air bladder.

Deflation

The Trim Grip™ is exclusively designed to allow deflation of the BC through

the Relief Valve while breathing from the Airsource. The Trim Grip incor-

porates dual activating cables for the Relief Valve. This, combined with the

angled mouthpiece, allows you to pull downward on the Trim Grip hose

without removing the Airsource from your mouth. The increased hose length

allows for greater range of head movement.

PRE-DIVE INSPECTION PROCEDURES

For your safety and to ensure the longest life of your equipment, we suggest

the following checklist to be followed each time before you enter the water:

1. Visually inspect the Airsource and the attached hoses for signs of deteriora-

tion or damage. If such signs are present, do not dive with the equipment.

2. Slowly open the tank valve to allow air to bleed into the regulator gradually.

3. Confirm the MP inflator hose is attached securely. Press the second

stage purge button on the Airsource to verify sufficient air flow. The regulator

should not continue to flow after the button is released.

4. Place the Airsource in your mouth and take several slow, deep breaths.

The regulator must deliver an adequate volume of air without requiring

excessive effort. If you are in doubt regarding this test, consult your scuba

instructor or an Aqualung

5. Close the cylinder valve and purge the remaining air in the regulator. Try

to inhale normally from the second stage mouthpiece on the Airsource. This

should create a vacuum in the second stage, and there should be no signs

of air flowing into the regulator case. Air flow may indicate a leak at the

mouthpiece, diaphragm, or exhaust valve. If a leak is detected, do not use

the Airsource until it is repaired.

6. If the Airsource passes the above predive check, reopen the cylinder valve

in preparation for the dive.

7. Once you have donned all your gear and are ready to enter the water,

always have your dive partner perform a final inspection cross check of the

Airsource and all other gear.
