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


• 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


• 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


• 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

Cleaning & LubricationCleaning & Lubrication

Go directly to Reassembly

Cleaning ProceduresCleaning Procedures

• Brass and Stainless Steel Parts

– Pre-clean in warm soapy water; nylon bristle brush

– Ultrasonically clean with soapy water; vinegar OK on tough corrosion

– Rinse in fresh water; use distilled water if tap water is “hard”

– Blow dry with hydrocarbon free gas (for EAN use)


• Aluminum, Plastic & Rubber Parts

– Soak in warm, soapy water

– Use soft nylon bristle brush to remove deposits

– Rinse with fresh water

– Blow dry with LP hydrocarbon free gas (for EAN use)

CAUTION: DO NOT soak plastic parts in acidic solutions !


• Regulator Hose

– Hose fittings - Ultrasonically clean with soapy water; vinegar OK on tough corrosion

– Can run soapy water through hose if needed

– Thoroughly rinse with fresh water

– Blow out hose before installing

Lubrication ProceduresLubrication Procedures

• Lubrication

– Christo-lube MCG 111

– Light film only

– Remove visible excess

– If regulator will be used with EAN, you should wear powderless, latex gloves (or equivalent) when lubricating and handling o-rings

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


• 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

!


• With relief valve open on gauge, slowly open cyl. valve & pressurize the 1st stage


• 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



– 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.



– 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.


• 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


• 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.
