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 gradu-

ally.

3. Confirm the Cut-off valve is in the open (down) position. Press the second

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

tor 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 Aqua Lung

5. close the cut-off 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 cut-off valve

in preparation for the dive.

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

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

Airsource and all other gear.
