Features (Yoke & DIN Available) 3365 psi yoke (232 Bar) 4351 psi DIN (300 Bar)
Features (Environmental Dry Kit) Supreme models come with dry kit –Allows 1st stage to be used in cold waters <50f (10c) –Insulates main spring with air –Prevents ice formation on the spring coils –Side benefit – keeps contaminants and corrosion out
Features (Nitrox Compatible) The Titan is nitrox (EAN) compatible to 40% out of the box Built with a high level of cleanliness EAN compatible components and lubricants Have passed required adiabatic compression testing to ensure their safety and compatibility
Features (Nitrox Compatible) Responsibility of the owner to maintain the cleanliness of the regulator If regulator will be used interchangeably with breathing air, the air should be oxygen-compatible or hyper-filtered whereas the condensed hydrocarbons do not exceed 0.1 mg/m3 Grade E air does not necessarily meet this criterion Hydrocarbons found in Grade E air can pose a risk in the presence of elevated oxygen content
Features (Nitrox Compatible) Hydrocarbons build up over time along the passageways of the equipment When hydrocarbons come in contact with high- pressure oxygen enriched air, they can pose a very real hazard that can lead to combustion If a regulator has had use with Grade E breathing air, it should receive a standard overhaul, including ultrasonic cleaning with a detergent solution, that removes hydrocarbons, prior to being put back into nitrox service
Features (Nitrox Compatible) Although second stage components are not exposed to high pressure EAN, Aqualung recommends that the same cleaning procedures be followed for the complete regulator This prevents the possibility of cross contamination and guarantees the cleanliness of the entire regulator

Adjusting Medium Pressure (MP) Install MP gauge (p/n 111610) into 1 st stage MP port –If gauge lacks over-pressure relief valve, attach properly adjusted 2 nd stage as relief valve in case of HP leak
Adjusting Medium Pressure (MP) Attach Titan to fully charged cylinder 3000 psi (206 bar)
WARNING If the pressure gauge rapidly exceeds 145 psi (10 bar), there is a HP leak. Quickly close the cylinder valve and purge the regulator. Failure to do so may cause a rupture to the MP hose and/or MP gauge which, in turn, can lead to personal injury !
Adjusting Medium Pressure (MP) With relief valve open on gauge, slowly open cyl. valve & pressurize the 1st stage
Adjusting Medium Pressure (MP) Close the relief valve –If MP rapidly exceeds 145 psi (10 bar ), close cylinder immediately and purge line –This means that there is a HP leak
Adjusting Medium Pressure (MP) Use a 8mm hex key –To increase the MP, turn the adj. screw in 1/8 turn increments clockwise –Using the relief valve on the gauge, cycle the reg. several times after each adj.
Adjusting Medium Pressure (MP) Use a 8mm hex key –To decrease the MP, turn the adj. screw in 1/8 turn increments counter-clockwise –Using the relief valve on the gauge, cycle the reg. several times after each adj.
Adjusting Medium Pressure (MP) Set the MP to: –135 psi (9.3 bar ) for standard –123 psi (8.4 bar) for supreme –The Titan 1 st stage is used with several different 2 nd stages, confirm MP settings by checking the appropriate 2 nd stage service manual MP Settings: 135 psi (9.3 bar) std. 123 psi (8.4 bar) supreme
Adjusting Medium Pressure (MP) Let the Titan stand for several minutes –Check that MP remains stable –If MP rises more than 5 psi (0.3 bar ), it indicates a leak –If stable, close valve, purge line & pressurize once again to perform final check Click here for Dry kit
Dry Kit Installation Keep Titan pressurized Install a new external diaphragm into the retainer –Drop in load transmitter, replace decal if necessary
Tighten Retainer Use retainer wrench (p/n 081247) –Tighten retainer until metal meets metal –NOTE: The MP should not change during this procedure
Immersion Test –Observe for leaks –Troubleshoot accordingly With the Titan still pressurized, submerge the unit in a tub of water NOTE: Do not confuse bubbles from trapped air with a true leak. If there is an air leak, bubbles will come out in a constant stream.
