4 O-ring Removal (Pinch Method) Pinch Method: Using fingers, push on opposite sides to create protrusionUse only brass or plastic pics to remove o-rings, this will protect delicate seating surfacesNever reuse o-ringsP/n
6 Features A time proven, in-line, balanced, diaphragm mechanism 1 HP port, 4 MP portsAll MP ports are 3/8”Turbo assistedAvailable in 232 bar yoke or 300 bar DINEnvironmental dry kit is availableMP can be set externallyCompatible to EAN 40, new out of box
7 Features (Balanced Diaphragm) Balanced ModelSeawater enters main spring chamber and acts directly on main diaphragmDiaphragm design 1st stages by design are sealed
10 Features (Yoke & DIN Available) 4351 psi DIN (300 Bar)3365 psi yoke (232 Bar)
11 Features (Environmental Dry Kit) Supreme models come with dry kitAllows 1st stage to be used in cold waters <50f (10c)Insulates main spring with airPrevents ice formation on the spring coilsSide benefit – keeps contaminants and corrosion out
12 Features (Nitrox Compatible) The Titan is nitrox (EAN) compatible to 40% out of the boxBuilt with a high level of cleanlinessEAN compatible components and lubricantsHave passed required adiabatic compression testing to ensure their safety and compatibility
13 Features (Nitrox Compatible) Responsibility of the owner to maintain the cleanliness of the regulatorIf 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/m3Grade E air does not necessarily meet this criterionHydrocarbons found in Grade E air can pose a risk in the presence of elevated oxygen content
14 Features (Nitrox Compatible) Hydrocarbons build up over time along the passageways of the equipmentWhen hydrocarbons come in contact with high-pressure oxygen enriched air, they can pose a very real hazard that can lead to combustionIf 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
15 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 regulatorThis prevents the possibility of cross contamination and guarantees the cleanliness of the entire regulator

36 Remove Diaphragm ! Insert a LP nozzle into one of the MP ports Use a blast of air to lift the diaphragmKeep finger over diaphragm to keep from ejectingCAUTION: Never remove diaphragm by prying or digging it out around the edges!Click here for alternate method of diaphragm removal
38 Remove Diaphragm (Alt. Method) If a LP nozzle is not available, you may leave the diaphragm in place for the time beingAfter disassembling the HP side of the first stage, you can reach through the body to push out the diaphragmCAUTION: Never remove diaphragm by prying or digging it out around the edges!
39 Remove Circlip ! ! Use circlip pliers (p/n 111100) CAUTION: Contents are under spring pressureKeeping finger over work to prevent parts from ejecting, carefully remove circlipCAUTION: Never remove diaphragm by prying or digging it out around the edges.!

47 Cleaning & Lubrication Go directly to Reassembly
48 Cleaning Procedures Brass and Stainless Steel Parts Pre-clean in warm soapy water; nylon bristle brushUltrasonically clean with soapy water; vinegar OK on tough corrosionRinse in fresh water; use distilled water if tap water is “hard”Blow dry with hydrocarbon free gas (for EAN use)
49 Cleaning Procedures Aluminum, Plastic & Rubber Parts ! Soak in warm, soapy waterUse soft nylon bristle brush to remove depositsRinse with fresh waterBlow dry with LP hydrocarbon free gas (for EAN use)!CAUTION: DO NOT soak plastic parts in acidic solutions
50 Cleaning Procedures Regulator Hose Hose fittings - Ultrasonically clean with soapy water; vinegar OK on tough corrosionCan run soapy water through hose if neededThoroughly rinse with fresh waterBlow out hose before installing
51 Lubrication Procedures Christo-lube MCG 111Light film onlyRemove visible excessIf regulator will be used with EAN, you should wear powderless, latex gloves (or equivalent) when lubricating and handling o-rings
62 Place The HP Block ToolSet the HP block tool (p/n ) with recessed edge facing down, onto the inlet boss
63 Install Filter Lay the filter flat inside block tool The rough side of the filter should face up
64 Install Filter WasherLay the washer on top of the filter
65 Install Circlip Install circlip inside the block tool The sharp edges should be facing up
66 Compress The Parts Use a ½” wooden dowel Compress the parts until the circlip engages in it’s respective groove
67 Inspect CirclipInspect the circlip, it should be seated evenly and fully expanded into it’s designated grooveCAUTION: Failure to fully seat the circlip could result in the ejection of parts from the first stage.!
68 Insert Pin In Center Bore Pin should engage the central hole of the HP seat on the other side
76 Apply Proper TorqueUse a ft/lb torque wrench & spring retainer socket (p/n ) with 3 inch ext.Torque to 18 ft/lbs (24.5 Nm)30mm crow foot can also be used on standard Titan34mm crow foot for supreme TitanTorque: ft/lbs Nm
84 Add O-rings To Retainer Install o-ring to the base of the retainerInstall an unlubricated o-ring to the retainer faceCAUTION: Inspect the retainer and replace old version with new revision!Click here to learn about handwheel retainer revisions
85 Torque Handwheel Retainer Use an in/lb torque wrench and a 6mm hex key adapterTorque to in/lbs (9.6 Nm)Torque: in/lbs Nm
89 Adjusting Medium Pressure (MP) Install MP gauge (p/n ) into 1st stage MP portIf gauge lacks over-pressure relief valve, attach properly adjusted 2nd stage as relief valve in case of HP leak
90 Adjusting Medium Pressure (MP) Attach Titan to fully charged cylinder psi (206 bar)
91 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
92 Adjusting Medium Pressure (MP) With relief valve open on gauge, slowly open cyl. valve & pressurize the 1st stage
93 Adjusting Medium Pressure (MP) Close the relief valveIf MP rapidly exceeds 145 psi (10 bar), close cylinder immediately and purge lineThis means that there is a HP leak
94 Adjusting Medium Pressure (MP) Use a 8mm hex keyTo increase the MP, turn the adj. screw in 1/8 turn increments clockwiseUsing the relief valve on the gauge, cycle the reg. several times after each adj.
95 Adjusting Medium Pressure (MP) Use a 8mm hex keyTo decrease the MP, turn the adj. screw in 1/8 turn increments counter-clockwiseUsing the relief valve on the gauge, cycle the reg. several times after each adj.
96 Adjusting Medium Pressure (MP) Set the MP to:135 psi (9.3 bar) for standard123 psi (8.4 bar) for supremeThe Titan 1st stage is used with several different 2nd stages, confirm MP settings by checking the appropriate 2nd stage service manualMP Settings: psi (9.3 bar) std psi (8.4 bar) supreme
97 Adjusting Medium Pressure (MP) Let the Titan stand for several minutesClick herefor Dry kitCheck that MP remains stableIf MP rises more than 5 psi (0.3 bar), it indicates a leakIf stable, close valve, purge line & pressurize once again to perform final check
98 Dry Kit InstallationKeep Titan pressurizedDrop in load transmitter, replace decal if necessaryInstall a new external diaphragm into the retainer
99 Tighten Retainer Use retainer wrench (p/n 081247) Tighten retainer until metal meets metalNOTE: The MP should not change during this procedure
100 Immersion TestWith the Titan still pressurized, submerge the unit in a tub of waterObserve for leaksTroubleshoot accordinglyNOTE: 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.
