Page 3 REGULATORS AIR XS ALTERNATE INFLATOR REMOVING THE AIRWAY FROM THE BC 1. Using a Retaining Nut Tool, turn the nut portion of the upper housing assembly(7) counter clockwise to loosen and remove the airway assembly from the BC upper valve retainer. (Fig. 1) 2.
Page 4 REGULATORS AIR XS ALTERNATE INFLATOR a. Being careful to avoid damaging the corrugated airway hose(11), snip the tie wrap(10) that holds the hose onto the upper housing(7) and gently pull it off and away from the housing. b. Using a 1/16" drift pin punch, lightly tap the rapid exhaust arm pin(8) out of the housing.
Page 5 REGULATORS AIR XS ALTERNATE INFLATOR e. Fasten a plastic tie-wrap(10) around the groove of airway tube. Tighten the tie-wrap with the lock tab positioned at the side of upper housing assembly. Snip off the excess. Hold the pull ball(12) so that the cable pin hole portion of the ball is down (Fig.
Page 6 DO NOT overtighten. LOWER (POWER) INFLATOR DISASSEMBLY & SERVICE Fig. 6 NOTE: Oceanic recommends that all gaskets, nonmetal filters and o-rings, both static and dynamic, that are removed during disassembly of the Lower Inflator should be discarded and replaced with new.
Page 7 REGULATORS AIR XS ALTERNATE INFLATOR 4. To remove the colored button slide(25) use a small screwdriver to gently pry the sides of the slide, one side at a time, away from the housing. (Fig. 7). NOTE: Use only enough pressure lifting the sides of the button slide to release the four slide retaining tabs from the housing.
Page 8 18. Remove the poppet seat(21) from the poppet(22) with the use of a brass o-ring tool. Discard and DO NOT attempt to reuse. 19. Using the Air XS multi-tool (side A), remove the exhaust valve cover(42) by turning the tool counter clockwise with slight inward pressure.
Page 9 REGULATORS AIR XS ALTERNATE INFLATOR 24. Using the Air XS multi-tool (side C), remove the oral valve seat(36) by turning the tool counter clockwise with slight inward pressure. Remove the valve seat gasket(35) that may be found seated either on the underside of the oral valve seat(36) or inside the hous- ing(24).
Page 10 10. Place the exhaust valve frame(40) with exhaust valve and gasket onto the Air XS multi-tool (side B). Lower the housing(24) onto the Air XS multi-tool with exhaust valve frame facing up. Turn the tool clockwise into the housing(24) until secure.
Page 11 WARNING: It is very important that the poppet is adjusted using the Oceanic poppet installation tool exactly as de- scribed in step 16. The lever arm may otherwise become caught on the end of the poppet shaft, resulting in an uncontrolled free flow or leakage.
Page 12 Place the front cover(44) directly over the dia- phragm, and ensure that it seats flush and that the Oceanic logo is properly aligned. 29. While holding the front cover(44) secure with your thumb, thread the front cover retaining ring(45) onto the housing(24), taking care to ensure that it is correctly seated on the threads.

Page 14 4. Hold the Air XS with the front cover facing directly up, and gently shake up and down. Listen for excessive rattle that may be present, indicating lever slack. Some lever slack is considered normal due to the close proximity of the soft urethane front cover to the inhalation diaphragm.
Page 15 BC as described in Installing the Airway onto the BC before proceeding further. 6. Attach the Air XS to a pure air source, via a quick disconnect LP hose, and perform the General Air Leak Inspection as described in Buoyancy Compensator General Procedures (Section 5.1) to ensure that leakage is not present and the inflation, deflation, over pressure relief valve, and pull dump are functioning perfectly.
