COMPATIBILITY AND INSTALLATION
The AIR XS II low pressure inflator hose is compatible with all Oceanic first stage regulators. It may not be
compatible with other manufacturers' first stages (thread size = 3/8-24 UNF).
Have your AIR XS II installed on your BC, and the low pressure inflator hose attached to your regulator first
stage, by an Authorized Oceanic Dealer.
Connect the quick disconnect (QD) end of the inflator hose to the AIR XS II using the QD coupling. To at-
tach it, grasp the coupling on the end of the inflator hose between the palm of your hand and fingers, and
pull back the coupling release with your thumb and forefinger.
While holding back the coupling release, press it onto the quick release fitting on the AIR XS II, and
let go of the coupling release while continuing to hold the hose onto the quick release fitting.
Ensure they are firmly attached prior to pressurizing the regulator/inflator system.
NOTE: Refer to the illustration on page 2 for identification of components.
FEATURES
OPERATING BUTTONS
The three operating buttons, one located on each side of the mouthpiece and one above the mouthpiece,
can be differentiated by look, position, and tactile feel. Become familiar with their use to minimize the
possibility of confusion.
• Top - regulator purge button
• Left - power inflator button
• Right - manual inflator/deflator button

CORRUGATED HOSES/PULL CONNECTOR
Two corrugated hoses are joined by a Pull Connector. By pulling on the rounded Pull Connector you can
operate the Rapid Exhaust Valve located in the upper (shoulder) unit while you are using the AIR XS II
Regulator without having to remove the Regulator from your mouth. The extended length of the Hose As-
sembly prevents any resistance during head movement.
INFLATOR OVERPRESSURE RELIEF VALVE (OPV)
The integrated OPV, located in the upper (shoulder) unit, automatically vents excess pressure from the BC
during ascent or if over pressurized with the Power Inflator. This component of the AIR XS II operates auto-
matically so no instructions for its use are necessary.
WARNING: The OPV integrated into the upper (shoulder) unit is set to operate
at a lower relief pressure than the OPV located on the back of the BC to prevent
damage to the material of the BC air cell. It is imperative that only Oceanic
inflator assemblies be used with Oceanic BCs.
QUICK DISCONNECT CAP (SEE ILLUSTRATION ON PAGE 2)
The rubber Cap secured to the corrugated hose is provided to cover the quick release inlet fitting of the
AIR XS II Power Inflator Assembly. The Cap must be installed any time the Inflator Hose is disconnected to
prevent entry of contaminants.
INFLATOR OPERATION
WARNING: If you ever hear air, or see bubbles, escaping from the area around
any of the AIR XS II's connectors, or if the BC fails to hold air, immediately
terminate or postpone the dive until the BC and AIR XS II can be serviced by
an Authorized Oceanic Dealer. You must not dive with an AIR XS II or BC that
exhibits any signs or symptoms of leakage.
7
BC INFLATION USING THE POWER INFLATOR
With your Regulator connected to an appropriate cylinder, slowly open the cylinder valve to pressurize the
Regulator/Inflator system. Press the Power Inflator Button, located on the left side of the AIR XS II Mouth-
piece, until you hear air flowing into the BC. Minor compressions of the Power Inflator Button will initiate
airflow into the BC and allow small adjustments in buoyancy.
WARNING: If you depress the Power Inflator Button fully, the BC will inflate
rapidly. Be careful not to overinflate the BC during a dive causing an unwanted
rapid rise toward the surface.
Test the Power Inflator and Overpressure Relief Valve (OPV) prior to each dive to ensure they are function-
ing properly. Depress the Power Inflator until the BC fills completely, forcing the OPV in the upper (shoul-
der) unit to open. You will hear the sound of air venting from OPV, indicating that it is working properly.
While the BC is still inflated, listen for any undesired air leakage around the AIR XS II. The BC should stay
inflated until you deflate it manually.
BC DEFLATION USING THE RAPID EXHAUST VALVE (REV)
The Rapid Exhaust Valve (REV) is located inside the upper (shoulder) unit of the Inflator Assembly. It is con-
nected to the lower (power) unit by two Cables located inside the Corrugated Hose and coupled together
inside the Pull Connector.
The REV is operated by grasping the Pull Connector, or the lower (power) unit and pulling it down (away)
from the upper (shoulder) unit. The Cables pull the Exhaust Valve open, venting air from the BC through
the Vents of the upper unit of the Inflator Assembly.
The amount of air vented depends on how far open the Exhaust Valve is, the distance you
pull the inner Cable, and how long the Exhaust Valve is open. Short tugs vent small amounts
of air for minor changes in buoyancy, and a long pull will vent the entire BC in a matter of
seconds.
8
Use of the REV eliminates water entry even if the Exhaust Valve remains open after all air is vented from
the BC.
BC INFLATION USING THE MANUAL INFLATE/DEFLATE BUTTON
The Round Button located on the right side of the Mouthpiece is an Inflate/Deflate manual actuator that al-
lows air flow in to, or out of, the BC. To inflate orally, place the Mouthpiece in your mouth, and after you
begin (and continue) to blow in, press the Button with your thumb. This procedure purges the mouthpiece
cavity of water, resulting in less water entering the BC, potentially prolonging Bladder life.
Some air may continue to leak in to the surrounding water when you are orally inflating the BC, even after
you have released the Inflate/Deflate Button. This is considered normal and will not impede the efficient
oral inflation of the BC.
BC DEFLATION USING THE MANUAL INFLATOR/DEFLATOR BUTTON
To deflate the BC through the Mouthpiece, hold the lower (power) unit higher than the top of the BC and
depress the Round Button located on the right side of the Mouthpiece to vent the air from the BC.
To ensure complete deflation of the BC, the Mouthpiece must be held higher than the top of the BC. While
underwater, you will hear the air as it bubbles out through the Mouthpiece.
To prevent entry of water into the BC, be sure to release the Button before all bubbles stop flowing. To
help eliminate unwanted water entry, use the Rapid Exhaust Valve method of deflation.
REGULATOR OPERATION
In the event that it is necessary for you to share air with another diver, you should offer your
Primary Second Stage to the diver and you should use the AIR XS II Regulator. Although the
AIR XS II Regulator will function properly with the Purge Button facing up or down, Oceanic
recommends an operational position with the Purge Button facing up, similar to other Second
Stage positioning.
9
Operation of your AIR XS II Regulator is similar to most other Second Stages. It provides air on demand
with low inhalation resistance and it has a convenient Purge Button located on the top of the unit's housing
and a comfortable Mouthpiece.
As with most other Second Stages, purging the AIR XS II Regulator of water can be accomplished in two
ways. By pressing the Purge Button to initiate the flow of air and expulsion of water, or by exhaling a
small puff of air into the Mouthpiece to expel the water.
CARE AND MAINTENANCE
Your AIR XS II is a reliable piece of equipment that will continue to work like new for many years to come,
if cared for properly.
Follow the procedures below, and have the entire AIR XS II inspected and serviced annually by your local
Authorized Oceanic Dealer.
DISCONNECTING THE INFLATOR HOSE
• Close the Cylinder Valve and purge (vent) the Regulator Assembly 'completely' of all pressure by
depressing a second stage Purge Button.
• Grasp the Quick Disconnect Coupling on the AIR XS II Inflator Hose (second stage end) between the
palm of your hand and fingers, pull back the Coupling Release with your thumb and forefinger, and
pull it off the quick release fitting of the AIR XS II.
• Place the Protective Cap on the fitting (see illustration on page 2) to prevent contaminants from enter-
ing the AIR XS II's Valve Housing.
POST DIVE CARE
Any exposure to aquatic elements can produce contamination that could effect the proper function of your
dive equipment. Post dive care is the most important thing you can do to keep your AIR XS II in top condi-
tion.
10
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.
