6 6 Odyssea Technical Manual Introduction This manual provides factory prescribed procedures for the correct service and repair of the Aqua Lung product described in this manual. It is not intended to be used as an instructional manual for untrained personnel. The procedures outlined within this manual are to be performed only by personnel who have received Factory Authorized training through an Aqua Lung Service & Repair Seminar. If you do not completely understand all of the procedures outlined in this manual, contact Aqua Lung to speak directly with a Technical Advisor before proceeding any further. It is recommended that the Odyssea should be rinsed in fresh water after use, and it should be stripped down and serviced annually. However, if at all unsure about the correct functioning of the Odyssea, then it must be officially inspected immediately. An Official Inspection consists of: 1. Testing instructions see Pre-Dive Inspection. 2. Orally inflate the Odyssea. Check that the over pressure relief valve (OPRV)/rapid exhaust valve (REV) are operating correctly, tightened down properly and no leaks are detected. 3. A visual inspection of the Odyssea checking that there is no excess wear to the hook/loop material, stitching points are not excessively coming undone, quick release buckles are in good working order and outer bag zipper is moving freely. 4. Auxiliary cylinder is full and no leaks are detected. If the Odyssea fails any of the 4 steps it should be serviced by an Aqua Lung trained service technician. General Guidelines 1. In order to correctly perform the procedures outlined in this manual, it is important to follow each step exactly in the order given. Read over the entire manual to become familiar with all procedures before attempting to disassemble the product in this manual, and to learn which specialty tools and replacement parts will be required. Keep the manual open beside you for reference while performing each procedure. Do not rely on memory. 2. All service and repair should be carried out in a work area specifically set up and equipped for the task. Adequate lighting, cleanliness, and easy access to all required tools are essential for an efficient repair facility. 3. As the valve/inflator is disassembled, reusable components should be segregated and not allowed to intermix with nonreusable parts or parts from other units. Delicate parts, including inlet fittings and crowns which contain critical sealing surfaces, must be protected and isolated from other parts to prevent damage during the cleaning procedure. 4. Use only genuine Aqua Lung parts provided in the overhaul parts kit for this product. DO NOT attempt to substitute an Aqua Lung part with another manufacturer s, regardless of any similarity in shape or size. 5. Do not attempt to reuse mandatory replacement parts under any circumstances, regardless of the amount of use the product has received since it was manufactured or last serviced. 6. When reassembling, it is important to follow every torque specification prescribed in this manual, using a calibrated torque wrench. Most parts are made of either marine brass or plastic, and can be permanently damaged by excessive stress. General Conventions Unless otherwise instructed, the following terminology and techniques are assumed: 1. When instructed to remove, unscrew, or loosen a threaded part, turn the part counter-clockwise. 2. When instructed to install, screw in, or tighten a threaded part, turn the part clockwise. 3. When instructed to remove an o-ring, use the pinch method (see illustration below) if possible, or use brass or plastic o-ring removal tool. Avoid using hardened steel picks, as they may damage the o-ring sealing surface. All o-rings that are removed are discarded and replaced with brand new o-rings. Pinch Method Press upwards on sides of o-ring to create a protrusion. Grab o-ring or insert o-ring tool at protrusion.

7 7 CAUTION: Use only a plastic (pn ) or brass o-ring removal tool (pn ) when removing o-rings to prevent damage to the sealing surface. Even a small scratch across an o-ring sealing surface could result in leakage. Once an o-ring sealing surface has been damaged, the part must be replaced with new. DO NOT use a dental pick or any other steel instrument. 4. The following acronyms are used throughout the manual: MP is Medium Pressure; HP is High Pressure; LP is Low Pressure. 5. Numbers in parentheses reference the key numbers on the exploded parts schematics. For example, in the statement,...remove the o-ring (45) from the valve body..., the number 45 is the key number to the o-ring. NOTE: Before performing any disassembly, refer to the exploded parts drawing, which references all mandatory replacement parts. These parts should be replaced with new, and must not be reused under any circumstances, regardless of the age of the regulator or how much use it has received since it was last serviced.

8 8 Odyssea Technical Manual GENERAL PRECAUTIONS & WARNINGS WARNING: Before using the Odyssea, you must have successfully received training and certification in the technique of SCUBA diving from a Military or government operated diving school (or any recognized certification agency). Use of this equipment by a person who is not certified by a recognized agency shall render all warranties, express or implied, null and void. WARNING: Use of SCUBA equipment by uncertified or untrained persons is dangerous and can result in serious injury or death. WARNING: In an emergency such as an out of air situation or uncontrolled rapid descent, it is important to immediately remove and jettison weight immediately. WARNING: In the event of an uncontrolled, rapid ascent, it is important to immediately begin venting air from the Odyssea. Continue venting air to slow your ascent rate if neutral buoyancy cannot be reestablished. WARNING: Your jacket is not a lift bag. DO NOT rely on it to bring heavy objects to the surface. Doing so may permanently damage the jacket, and could result in serious injury or death. WARNING: NEVER lubricate any part of the jacket with any lubricant. Lubrication of certain parts and assemblies must only be performed by Aqua Lung trained service technician. WARNING: Do not apply any type of aerosol spray to the jacket. Doing so may damage certain plastic components, including important valve connections. WARNING: Repair, service, or disassembly must not be attempted by persons who are not factory trained and authorized by Aqua Lung. Unauthorized service will render the warranty null and void. WARNING: The Odyssea is NOT a life jacket! It is not designed to provide face-up flotation in all situations; therefore it does not meet U.S. Coast Guard regulations for a life preserver or personal flotation device (PFD). If you become unconscious in the water without a buddy present to immediately give assistance, you may suffer serious injury or death from drowning. Your jacket primarily designed to help you maintain neutral buoyancy while in a comfortably balanced, face-down swimming position underwater. It is also designed to provide you with flotation so that you can rest on the surface, but it is not designed to function as a life preserver or personal flotation device (PFD). In order to meet U.S. Coast Guard regulations, a PFD must be designed so that it automatically rights you to a face-up position and holds your head out of the water on the surface. The design characteristics of a personal flotation device are different from those of a buoyancy compensator. The ability of any flotation device to float you in a face-up position can also be affected by other diving equipment you wear, including a cylinder, weight or exposure suit, and whether it can be inflated before you lose consciousness. For this reason, it is important always to dive with a buddy, and maintain close proximity with them at all times. Do not depend on any flotation device to hold your face above the surface in the event that you are rendered unconscious in the water while diving. WARNING: Although this manual provides some basic guidelines for certain buoyancy control techniques, it is not a substitute for training from a professional diving instructor. Failure to weight yourself properly may create a hazardous condition that could lead to serious injury or death. If you are unsure how to weight yourself in order to achieve optimum buoyancy underwater and on the surface, do not dive until you have obtained the necessary instruction from your diving instructor. If you have any questions regarding your Buoyancy Compensator or these instructions, contact Aqua Lung at (760)

9 9 PRODUCT OVERVIEW This buoyancy jacket is specifically designed for military use with all types of back or chest-worn breathing apparatus, including semi-closed circuit or closed circuit rebreathers. The Odyssea features an air cylinder attachment that allows you to inflate the jacket with compressed breathing air. The air cylinder comes equipped with a standard connection for use on the jacket. The breathable inflator allows you to breathe from the bladder in an emergency situation. The distribution of the buoyancy chambers provides excellent safety performance, either during buoyant ascent (vertical stability) or at the surface (natural support position with head and shoulders out of water). The bladder is constructed of heavy duty urethane and is encosed in a 840 Denier nylon bag that resists cuts, tears and abrasion. Two drains with tethered caps on the bottom side makes draining fast and easy. The jacket has specially designed retainers for an emergency strobe light and a snorkel. In addition, it has a utility pocket located on the left front lobe. The Odyssea is suitable for all types of use. It must be fitted with an inconel cylinder to be completely non-magnetic. SPECIAL FEATURES BC Air Breathing The oral inflator is equipped with a breathing valve that allows the diver to breathe air from the buoyancy compensator. This device is only to be used in case of emergency. To breathe air from your BC, first slightly exhale through the oral inflator mouthpiece in order to remove the excess of water trapped in the mouthpiece s body (Fig 1). Then, inhale through the mouthpiece. This will activate the breathing valve and deliver air from the BC bladder. When done inhaling, exhale through the mouthpiece. The breathing valve permits both inhaling and exhaling with out any manipulation. Oral Inflator Mouthpiece Fig. 1 PN WARNING: Always keep in mind that breathing air from the BC also deflates the BC and changes your buoyancy. Always be prepared to add air in the BC from the emergency cylinder in order to get extra air to breathe and also extra buoyancy. Depending on the depth, the auxiliary cylinder will only provide a few minutes of air, so you must immediately start a controlled ascent to the surface. CAUTION: The inside of the bladder must be kept dry and clean of all contaminants. If not maintained properly, breathing from the BC in the case of an emergency could cause suffocation or asphyxiation due to contamination.

10 10 Odyssea Technical Manual Pocket The Odyssea features one large utility pocket located on the left front lobe of the BC, and two retainers on the right side designed to carry an emergency strobe light and a snorkel. Drain Plug The Odyssea is equipped with 2 drain plugs located on the back of each lobe of the BC. The plugs are used to rinse the inside of the bladder (see post dive care and maintenance section). AUXILIARY AIR CYLINDER The auxiliary cylinder is attached to the Odyssea by means of a threaded hand fitting (Fig. 2). Air is added to the Odyssea by opening the cylinder valve. Required for closed circuit and semi-closed circuit diving. P/N P/N Fig. 2 Filling the Auxiliary Cylinder To fill the cylinder, you will need the optional fill adapter w/ standard connection (Aqua Lung part number ). 1. Before attempting to fill the auxiliary cylinder, ensure that the fill adapter and valve are completely dry - especially in the area surrounding the valve outlet. Examine the cylinder markings to verify that it is rated for a fill pressure of 3,000 PSI (206 BAR). 2. Using a calibrated pressure gauge, check the supply cylinder is filled to 3,000 PSI (206 BAR). It is very important to ensure that the auxiliary cylinder is filled to its total capacity, but not overfilled. WARNING: DO NOT attempt to fill the cylinder if the markings indicate that it is rated for a different fill pressure other than 3,000 PSI (206 BAR). Doing so may result in rupture or explosion in the event of fire or overfilling. Instead, immediately return the unit to a qualified technician and do not use under any circumstances.

11 11 3. Inspect the o-ring at the end of the fill adapter to make sure it is in good condition. Thread the adapter onto the threaded outlet boss on the cylinder valve until finger tight (Fig. 3). Check O-ring Fig. 3 Standard connection 4. Loosen the yoke knob. While supporting the auxiliary cylinder in one hand, attach the adapter to a fully pressurized 3,000 PSI (206 BAR) scuba cylinder (Fig. 4). Relief Plug Yoke Knob Fig Close the relief plug on the adapter by turning clockwise until finger tight. WARNING: DO NOT attempt to fill the auxiliary cylinder from a supply cylinder which contains more than 3,000 PSI (206 BAR). Doing so may weaken and damage the safety burst plug assembly and/or cylinder. 6. Open the handwheel on the auxiliary cylinder counter-clockwise until the valve is completely open. 7. VERY SLOWLY open the valve on the scuba cylinder. NOTE: Always fill the auxiliary cylinder as slowly as possible by turning the handwheel of the supply valve slowly to control the rate of fill. Rapid filling will generate heat and will result in an incomplete fill after the cylinder cools. Make sure not to over-inflate or inflate too rapidly. If the cylinder is warm to the touch afterward, the fill rate was too rapid.

12 12 Odyssea Technical Manual 8. Close the valve of the supply cylinder and then the valve of the auxiliary cylinder. Slowly loosen the relief valve by turning it counter-clockwise to relieve the high pressure air trapped in the adapter. 9. Loosen the yoke knob and remove the adapter from the supply cylinder. Unscrew the adapter from the auxiliary cylinder valve. Place the dust cap back in place and tighten the yoke knob. Attaching the Auxiliary Cylinder 1. Before attaching the cylinder, inspect the O-ring located at the tip of the connector (Fig. 5). Check O-ring Fig Insert the cylinder into the retaining sleeve and align the threaded valve outlet with the connector. Turn the connector nut clockwise and thread onto the valve outlet until finger tight (Fig. 6). Fig. 6

13 13 INFLATION METHODS Using the Oral Inflator To orally inflate your BC (Fig. 7), place your lips on the oral inflator mouthpiece (A) and exhale a small amount of air into the mouthpiece to purge any water that may still be in the housing. While continuing to exhale into the mouthpiece, depress the oral inflator button (B) to inflate the BC. Immediately after exhaling, release the oral inflator button to prevent air from escaping. A B Fig. 7 Using the Auxiliary Air Cylinder To inflate the BC using the auxiliary air cylinder, open the cylinder valve by turning the handwheel counter-clockwise. Close the cylinder valve when the bladder is adequately filled, otherwise, air will escape from the over pressure relief valves (OPRV). DEFLATION METHODS Throughout the course of a dive, it will be necessary to release air from the Odyssea using one of the three methods described in the following instructions. Each method uses a valve that is in a different location. The method you choose at any time may depend on whether you are making your initial descent feet-first, head-first, or maintaining neutral buoyancy underwater. Always remember to utilize the valve that is at the highest point on the bladder (closest to the surface), depending on your position in the water. Deflation via Oral Inflator To deflate the Odyssea using the oral inflator, lift the inflator body to its highest possible position (above the head). Press the oral inflator button (Fig. 7b) to start venting air. This method is most effective on the surface when starting the initial descent. NOTE: Depressing the oral inflator while the jacket is empty may cause water to enter the air bladder.

14 14 Odyssea Technical Manual Deflation via Dual Exhaust Valve Inside the inflator s corrugated hose is a nylon cord that attaches the inflator to the dual valve at the top of the airway assembly. You can vent air from the Odyssea by firmly pulling straight down on the inflator. Once resistance is felt, only a pull of.25 in (7mm) is required. This rapid exhaust valve (REV) provides an effective and convenient way to vent air from the BC while in either an upright or facedown swimming position (Fig. 8). It also functions as an over pressure relief valve (OPRV) that will open automatically to relieve air pressure. This feature is very critical for preventing stress or damage to the BC s bladder (Fig. 9). Fig. 8 Fig. 9 Deflation via OPRV / Dump Valve In addition to the over pressure relief valve (OPRV) that is integrated into the dual valve, the Odyssea has another OPRV/dump valve (Fig. 10) located on the lower right lobe (A), opposite the auxiliary air cylinder attachment. The OPRV s primary function is to relieve excess air pressure inside the bladder, but it can also be opened manually by pulling on the ball and cord assembly (B) to quickly dump air. A B Fig. 10 CAUTION: The proper function of the over pressure relief valve is vital to prevent damage to the BC bladder. Unauthorized service or tampering may render these valves inoperable, and could cause the bladder to leak or burst. This type of damage is not repairable and is not covered under warranty. WARNING: Most training agencies recommend that you descend in an upright, feet-first position, in order to maintain a slower and more controlled descent. This is especially true if you experience difficulty equilizing your ears or if you are descending in low visibility conditions.

15 15 DONNING & ADJUSTMENT PROCEDURES Donning 1. One end of the crotch strap ( Fig.11) has a single male quick-release buckle. The other end has two male quick-release buckles.

A Fig. 12 Adjusting strap length 1. The length of the straps may be adjusted by holding the strap and moving the 3-bar slide (Fig. 11E) up or down the strap. After adjusting the position of the 3-bar slide, readjust the strap through the quick release buckle. 2. Once the straps are readjusted, don the Odyssea to make sure the adjustments are correct.

16 16 Odyssea Technical Manual PRE-DIVE INSPECTION WARNING: Before each use, the Odyssea must be given a thorough visual inspection and functional test. NEVER dive with an Odyssea that shows signs of damage to its bladder or valves until it has received a complete inspection and service from an authorized repair technician. 1. Orally inflate the Odyssea until the bladder is completely full. Manually operate the OPRV/dump valve by pulling on the attached ball and cord to release air from the Odyssea (Fig. 13). Release the ball and cord, verify the OPRV/dump valve re-seats. Re-inflate the jacket and pull down on the oral inflator assembly to check the function of the REV, only a pull of 7mm (.25 in) is required once resistance is felt (Fig. 14) Use cylinder air if required to activate OPRV. Pull Down On Oral Inflator Fig. 13 Fig Fully inflate the Odyssea once again and let it sit for 10 minutes to check for leaks and firmness (Fig. 15). WARNING: If you can hear any leaks, or if the bladder begins to deflate within 10 minutes, DO NOT attempt to use the Odyssea until it has received service. Fig. 15

17 17 3. Inspect all quick release buckles (both male and female ends) that are attached at the top, sides and on the crotch strap of the Odyssea for cracks, breakage or general damage. Please refer to the diagram in the donning and adjustment procedures section for specific quick release buckle locations (Figs ). Fig. 16 Fig. 17 Fig Check stitching points on the cylinder retaining sleeve, quick release buckles, webbing, crotch & lobe retaining straps.

20 20 Odyssea Technical Manual POST DIVE CARE & MAINTENANCE With proper care, the Odyssea will provide many years of reliable service. The following preventive maintenance must be performed to extend the life of the Odyssea: 1. Avoid prolonged exposure to direct sunlight and extreme heat. Nylon fabric can quickly fade when exposed to the sun s ultraviolet rays, and extreme heat may damage the welded bladder seams. 2. Avoid repeated or prolonged use in heavily chlorinated water, which can cause the Odyssea fabric to discolor and decay prematurely. 3. Do not allow the Odyssea to chafe against any sharp objects or rough surfaces that could abrade or puncture the bladder. Do not set or drop heavy objects such as block weights on the Odyssea. 4. Avoid any contact with oil, gasoline, aerosols, or chemical solvents. 5. After diving, give the Odyssea a thorough fresh water rinse. Unzip the outer shell and check for water inside the urethane air bladder. If there is any water inside the bladder, it must be rinsed out with fresh water using the following procedure: a) Unscrew one of the drain caps (Fig. 32). Fig. 32 b) Using a garden hose, fill the bladder until about a 1/4 full and reinstall the drain cap. Thoroughly shake the bladder so the water rinses the entire inside of the bladder. Unscrew both drain caps and let all the water drain from the bladder. Leave the drain caps off until the inside of the bladder is dry (Fig. 33 & 34). Fig. 33 Fig. 34

21 21 c) Remove the airway assembly from the Odyssea by unscrewing the collar at the base of the connector. Rinse the airway thoroughly with fresh water inside and out. Hang the airway by the oral inflator end to allow for complete drainage and drying. d) When components are completely dry, reinstall the drain caps, OPRV, cylinder connector and oral airway assembly. Orally inflate the Odyssea until it is partially inflated. Store the Odyssea partially inflated, away from direct sunlight, in a clean, dry area. Do not store in an enclosed space, such as a car trunk, where temperatures may fall below -18ºC (0ºF) or rise above 49ºC (120ºF).

22 22 Odyssea Technical Manual B.C. Bladder Removal 3. Unzip external zipper, push bladder connectors into the outer bag (50). Carefully remove the bladder (49), making sure the connectors do not get caught on the outer bag. 1. Unscrew the connector nut on the cylinder valve connector (48) and remove the cylinder (52) from the BC. After the cylinder has been removed, loosen the cylinder valve connector and remove from the bladder connection. 2. Use a brass (944022) or plastic (101302) o-ring tool to remove the gasket (1) from the connector. The gasket can be reused if in good condition. Remove all straps with quick release buckles (53 & 54), both caps (55), dump valve (56) and airway (51).

23 23 BC Bladder Installation 1. Insert the bladder (49) back into the outer bag (50) so that the connectors line up with the connector holes. 4. Turn the cylinder valve clockwise to the on position and inflate the bladder until the over pressure relief valve (OPRV) releases the excess air from the bladder. Turn off cylinder and remove the cylinder from the BC. Check both caps (55), dump valve (56), airway (51) and cylinder valve connector (48) for any signs of leakage. If no leakage is detected, let bladder stand inflated for one hour. Check the firmness of the bladder after one hour has passed. If the bladder has remained firm, no air loss has occurred. If the bladder has lost air, recheck all connections, inflate BC, submerge and check for leaks. 2. Inspect gasket(s) (1) for damage, this component may be reused if no damage is noticed. Use a shop towel to clean the gasket and any residue out of the connector groove as necessary. Place gasket(s) back into the connectors. Install caps (55), dump valve (56), and airway (51) back onto the corresponding connectors. Put strap assemblies (53 & 54) back into place. 3. Ensure the gasket (1) has been placed back into the connector in which the cylinder valve connector will be attached. Attach the cylinder valve connector (48) and turn clockwise until hand tight. Insert the auxiliary cylinder into the retaining sleeve and tighten the connector nut onto the cylinder valve adapter (44).

24 24 Odyssea Technical Manual Note: Before performing any disassembly, refer to the exploded parts drawing which references all mandatory replacement parts. These parts should be replaced with new and must not be reused under any circumstances regardless of age or how much use it has received since it was last serviced. 3. Pull back the hose (13) from the mouthpiece body (18). Press the pin (17) out from one side using a pin punch or similar tool to release the braided nylon cord (12). Remove the hose (13) from the dual valve assembly, set the dual valve assembly to the side. CAUTION: Use only a plastic (pn ) or brass o- ring removal tool (pn ) when removing o-rings to prevent damage to the sealing surface. Even a small scratch across an o-ring sealing surface could result in leakage. Once an o-ring sealing surface has been damaged, the part must be replaced with new. DO NOT use a dental pick or any other steel instrument. Airway Non-Mag Maintenance Procedures Airway (Non Mag) Disassembly Oral Inflator Disassembly 1. Using the spanner wrench (pn ) to hold the push button (26), remove the locknut (14) from the stem (22) with a 5.5mm nut driver. Use needle nose pliers to remove the washer (15) and the rubber valve (16). Discard nut (14) and rubber valve (15). 1. Turn the retaining collar and remove the dual valve assembly from the connector. Use a brass (944022) or plastic (101302) o-ring tool to remove the gasket (1) from the connector. The gasket can be reused if in good condition. 2. Using a straight blade screwdriver, carefully lift out the fingers of the cage (27) and remove it from lower inflator housing (20). 2. Using diagonal pliers (pn ), carefully remove the three clamps (11) from the spiral hose (13) securing the inflator and dual valve assemblies. CAUTION: Do not apply excessive force or pry against the housing/cage with the tip of the screwdriver. CAUTION: Do not cut the spiral hose while removing the clamp.

25 25 3. Remove the stem assembly and spring (21) through the front of the lower inflator housing (20). Remove the mouthpiece (19) from the mouthpiece body (18). Dual Valve Disassembly NOTE: The outer cap is bonded to the body of the dual valve assembly with a non-permanent adhesive. It will be necessary to separate this bond prior to performing further disassembly by carefully following the procedure outlined below. 4. Using the spanner wrench (pn ), turn the push button (26) counter-clockwise to loosen. It may be necessary to secure the stem (22) in a vise or a pair of soft jawed pliers to loosen the push button (26) as a small amount of Loctite 425 or 480 is used to secure the button. Ensure the stem is protected from damage. 1. Locate the seam that runs along the circumference between the dual valve body (2) and the outer cap (6), where the cap is fastened to the body. Using the plastic handle of a medium size screwdriver, or similar lightweight blunt instrument, rap sharply against all points of the seam on the cap to break the adhesive bond. Seam 5. Remove the push button (26), washer (25) and the inflator diaphragm (24) from the stem (22). Next, remove the plastic valve (23) from the stem. It may be necessary to secure the stem in a vise or a pair of soft jawed pliers to remove the plastic valve as a small amount of Loctite 425 or 480 is used on the threads of the stem (22). Once removed, discard the push button (26), washer (25), inflator diaphragm (24) and plastic valve (23). CAUTION: Do not apply excessive force or use a hammer, mallet or other heavy instrument. 2. While holding the dual valve assembly secure, firmly grasp the outer cap (6) and turn it counter-clockwise to loosen. While maintaining slight inward pressure to counteract the spring pressure inside, continue turning the cap (6) until it has disengaged from the dual valve body (2). Remove the cap and the spring (5) beneath it. Closely examine the cap to check for any signs of thread damage, distortion, cracking, or chemical attack that may indicate the use of excessive force or incorrect adhesive during previous service. 6. Clean any residual Loctite from the large threads of the stem (22). NOTE: If the cap cannot be turned, repeat step 1 to break the adhesive bond. This Concludes Disassembly of the Oral Inflator Before starting assembly, perform parts cleaning and lubrication in accordance with Procedure A: Cleaning and Lubricating in the back of the manual.

26 26 Odyssea Technical Manual 3. Remove the valve plate (4) with gasket (3) from the body (2) and remove the gasket from the valve plate. Discard the gasket and set the valve plate aside. NOTE: Before performing any assembly, it is important to inspect all parts, both new and those that are being reused, to ensure that every part and component is perfectly clean and free of any dust, corrosion or blemishes. Before dressing each o-ring with Christo-Lube, check to ensure it is clean, supple and free of any blemish. 4. Locate the two holes on opposite sides of the barrel of the dual valve body (2) which hold the arms of the poppet guide (10). To remove the poppet guide and exhaust valve assembly from the dual valve body, press the arms of the poppet guide inward by simultaneously inserting two small probes through the opposing holes in the barrel. WARNING: Use only genuine Aqua Lung parts, subassemblies and components whenever assembling any Aqua Lung product. DO NOT attempt to substitute an Aqua Lung part with another manufacturer s, regardless of any similarity in shape, size or appearance. Doing so may render the product unsafe and could result in serious injury or death. Oral Inflator Assembly 1. Place the large end of the spring (21) into the lower inflator housing (20). Ensure the spring is oriented properly. 5. When the arms of the poppet guide have disengaged from the body, firmly grasp the braided nylon cord (12) and pull the exhaust valve assembly straight out while holding the body secure. This will pull the poppet stem (8) out of the dump valve poppet (7). Remove the dump valve poppet and discard. 2.

35 35 3. While holding the dual valve assembly secure, firmly grasp the inflator assembly and pull it in a straight line directly away from the dual valve assembly. Check the attachment points of the spiral hose (13) at both the dual valve assembly and the inflator assembly. If any signs of damage or decay can be detected to the spiral hose, it is important to replace the spiral hose before proceeding any further. 6. Manually inflate the BC until it is taut and fully inflated. Press the deflation button (26) and then pull down on the oral inflator to ensure a rapid and unobstructed exhaust using both methods of deflation. Fully inflate the BC once again, and listen closely for any signs of leakage. Push to Deflate Pull hose down Pull Down On Oral Inflator To Deflate NOTE: Ensure the cylinder valve connector, oral airway assembly, caps and OPRV/dump valve are secured to the BC prior to submerging. Failure to do so will cause water to enter the internal bladder. 4. Immerse the inflator and surrounding area of the spiral tube in fresh water to wet the lower portion of the airway assembly. Grasp the spiral tube approximately six inches above the inflator assembly and pull the tube in a straight line away from the inflator with moderate force while holding the inflator secure. Check to ensure that no separation occurs at the attachment point, and the tube remains seated flush against the base of the inflator housing. 7. Connect the cylinder to the cylinder valve connector. Turn the cylinder valve clockwise to the on position and inflate the bladder until the over pressure relief valve (OPRV) releases the excess air from the bladder. Turn off cylinder and remove the cylinder from the BC. Check caps (55), airway (51), OPRV/Dump valve (56) and cylinder valve connector (48) for any signs of leakage. If no leakage is detected, let bladder stand inflated for one hour. Check the firmness of the bladder after one hour has passed. If the bladder has remained firm, no air loss has occurred. If the bladder has lost air, recheck all connections, inflate BC, submerge and check for leaks. If a continuous leak is detected, the component must be disassembled and examined for damage or contamination of the seals and seating surfaces. 5. Finally, bend the spiral hose at a right angle. If the spiral hose shows any sign of separating from the inflator assembly it is important to replace the clamp. NOTE: If leakage is not immediately detected, allow the BC to stand for at least one hour to ensure that none exists.

40 40 Odyssea Technical Manual Procedure A: Cleaning and Lubricating Cleaning Brass and Stainless Steel Parts 1. Preclean in warm, soapy water* using a nylon bristle tooth brush. 2. Thoroughly clean parts in an ultrasonic cleaner filled with soapy water. If there are stubborn deposits, household white distilled vinegar (acetic acid) in an ultrasonic cleaner will work well. DO NOT place plastic, rubber or silicone parts in vinegar. 3. Remove parts from the ultrasonic cleaner and rinse with fresh water. If tap water is extremely hard, place the parts in a bath of distilled water to prevent any mineral residue. Agitate lightly, and allow to soak for 5-10 minutes. Remove and blow dry with low pressure 25 PSI (1.7 BAR) filtered air. Inspect closely to ensure proper cleaning and like-new condition. Cleaning Plastic & Rubber Parts Parts made of plastic or rubber may be soaked and cleaned in a solution of warm water mixed with mild dish soap. Use only a soft nylon toothbrush to scrub away any deposits. Rinse in fresh water and thoroughly blow dry, using low pressure filtered air. CAUTION: Do not place plastic and rubber parts in acid solutions. Doing so may alter the physical properties of the component, causing it to prematurely degrade and/or break. Cleaning Hoses 1. Hose fittings: Ultrasonically clean with soapy water*, vinegar is OK on tough corrosion (only hose ends). 2. Run soapy water through hose if needed. 3. Thoroughly rinse with fresh water (hang with hose ends down). 4. Blow out hose before installing. Lubrication and Dressing All o-rings should be lubricated with Christo-Lube MCG 111. Dress the o-rings with a very light film of grease, and remove any visible excess by running the o-ring between thumb and forefinger. Avoid applying excessive amounts of Christo-Lube grease, as this will attract particulate matter that may cause damage to the o-ring. *Soapy water is defined as household grade liquid dishwashing detergent diluted in warm water.
