WARNING: DO NOT attempt to remove (or install) the AIR XS II from (on) a BC.
Improper installation may cause misoperation or BC failure underwater, possibly
resulting in serious injury or death. It will also void the warranty.
As soon as possible at the end of each day of diving:
• Flush the exterior of all components thoroughly with fresh water to remove dissolved salt and other
contaminants.
• Flush the Lower (Power) Assembly by running water into the Mouthpiece and out the Exhaust Ports.
DO NOT depress the Purge Button if the Assembly is connected to the First Stage Regulator, doing
so will allow water to flow into the sealed portion of the First Stage.
• If possible, immerse the entire Lower (Power) Assembly in a warm fresh water bath and soak for one
hour, preferably while still connected to the First Stage Regulator and pressurized.
• Remove from the bath and rinse all components of the Assembly with slow running fresh water. DO
NOT use full water pressure.
• Sand that has collected behind the Lower (Power) unit Cover (behind the Purge Button) can be rinsed
out by flushing tap water through the opening in the Cover. Do not pry or lift up on the Purge But-
ton, or use high pressure water that could damage the internal Diaphragm.
• If after thoroughly rinsing, sand or debris can still be heard rattling under the cover, take your BC/
AIR XS II Assembly to an Authorized Oceanic Dealer for inspection and cleaning.
WARNING: DO NOT remove the Purge Cover yourself. Improper replacement of
the Cover could result in an unexpected undesirable shut off of air delivery while
underwater.
• If possible, lay the complete Assembly flat in a cool, dry place (out of direct sunlight) and allow the
components to dry naturally.
• DO NOT inject or spray Lubricants into or onto the AIR XS II. Doing so can attract contamination
that could subsequently interfere with proper operation.
