Titan 1st Stage Service Program
O-ring Removal (Pinch Method)O-ring Removal (Pinch Method)
• Pinch Method: Using fingers, push on opposite sides to create protrusion
• Use only brass or plastic pics to remove o-rings, this will protect delicate seating surfaces
• Never reuse o-rings

• Available in 232 bar yoke or 300 bar DIN
• Environmental dry kit is available
• MP can be set externally
• Compatible to EAN 40, new out of box
Features (Balanced Diaphragm)Features (Balanced Diaphragm)• Balanced Model
– Seawater enters main spring chamber and acts directly on main diaphragm
– Diaphragm design 1st stages by design are sealed
Features (Balanced Diaphragm)Features (Balanced Diaphragm)
Features (Turbo Assist)Features (Turbo Assist)
Features (Yoke & DIN Available)Features (Yoke & DIN Available)
3365 psi yoke (232 Bar)
4351 psi DIN (300 Bar)
Features (Environmental Dry Kit)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)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)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)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)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

TestingTesting
Adjusting Medium Pressure (MP)Adjusting Medium Pressure (MP)
• Install MP gauge (p/n 111610) into 1st stage MP port
– If gauge lacks over-pressure relief valve, attach properly adjusted 2nd stage as relief valve in case of HP leak
Adjusting Medium Pressure (MP)Adjusting Medium Pressure (MP)
• Attach Titan to fully charged cylinder 3000 psi (206 bar)
WARNINGWARNING
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)Adjusting Medium Pressure (MP)
• With relief valve open on gauge, slowly open cyl. valve & pressurize the 1st stage
Adjusting Medium Pressure (MP)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)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)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)Adjusting Medium Pressure (MP)
• Set the MP to:
– 135 psi (9.3 bar) for standard
– 123 psi (8.4 bar) for supreme
– The Titan 1st stage is used with several different 2nd stages, confirm MP settings by checking the appropriate 2nd stage service manual
MP Settings: 135 psi (9.3 bar) std. 123 psi (8.4 bar) supreme
Adjusting Medium Pressure (MP)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

Immersion TestImmersion 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.
