Introduction ® Congratulations—and thank you—for choosing Aqua Lung. Your new regulator has been designed and manufactured with pride, according to the most exacting standards for quality and performance. Provided that it has been purchased new from an Authorized Aqua Lung Dealer, your regulator is covered by Aqua Lung’s exclusive 30-Day Satisfaction Guarantee™ and the Aqua Lung Two-Year Limited Warranty™.
Regulator Features The Aqua Lung family of regulators consists of many different models to satisfy a wide range of diving interests; from entry level sport diving, to advanced diving in more demanding and extreme conditions. By now, your Authorized Aqua Lung Dealer has already explained to you the specific features that your particular model offers, and you have made your purchase after comparing the benefits of these features to your individual diving needs and interests.
T UN 8 C K WISE ) R R E SIS T E LO TE C GR (C EA W E) IS (CO RESISTAN C SS LE ER-CLOCK E AN When the VAS is set to the “MAX” (or “+”) position, the regulator will provide maximum venturi assistance. This makes it easier to breathe at deeper depths and increased work loads. For normal sport diving conditions, the regulator will perform suitably if it is left set to the “MIN” (or “—”) position.
Supreme™ and Dry™ First Stage Environmental Protection For diving in cold water conditions, or commercial diving in contaminated water, Aqua Lung offers two different types of environmental first stage protection kits which seal the ambient chamber from the environment. This helps to prevent ice from forming inside the first stage ambient chamber, and effectively extends the life of the first stage diaphragm for regulators used in extremely polluted or contaminated water.
Preparation and Setup Turned in clockwise Aqua Lung America, Inc. recommends that you bring your regulator to your Authorized Aqua Lung Dealer for the installation of any accessory items, including instrumentation, LP quick disconnect hoses, and alternate air sources. Your dealer can also answer any questions you may have pertaining to the information in this manual. 1.
Mounting the First Stage Onto the Cylinder Valve (Yoke Connector) 1. Partially unscrew the yoke screw of the first stage regulator so that the dust cap can be removed from the filter and air inlet. 2. With the cylinder valve facing away from you, release a small amount of air from the cylinder by turning the handwheel counter-clockwise to open the valve only slightly. When air is heard exiting, immediately close the valve.
counter-clockwise until it is fully open, and then turn it back clockwise 4-2 turn. 5. Listen near the first stage to check for any leakage. If leakage is detected, immerse the first stage and cylinder valve while pressurized to determine the source. 6. If leakage has been detected, follow the procedure for removing the regulator from the cylinder valve on pages 22-23.
shoulder. Thread the first stage DIN connector into the cylinder valve and turn the handwheel clockwise by hand until it is lightly snug. DO NOT use tools to tighten. 3. If a submersible pressure gauge is attached to the first stage, ensure that the gauge is facing away from you. Pressurize the regulator by slowly turning the cylinder valve handwheel counter-clockwise. Continue to turn the cylinder valve handwheel counter-clockwise until fully open, and then back clockwise 4-2 turn. 4.
Pre-Dive Checkout Before each use, the regulator must be given a thorough visual inspection and functional test. NEVER dive with a regulator that shows signs of damage, or provides substandard performance until it has received complete inspection and service from an Authorized Aqua Lung Dealer. Inspection Checklist: 1. Carefully inspect all hoses at their fittings to ensure they are securely connected into their respective ports on the first stage.
internally corroded aluminum (white/ gray powder) or steel (rust) cylinder. In this event, the cylinder in question should be returned to the dive store for internal visual inspection. CAUTION: If discoloration or contaminant residue is found to be present on the surface of the filter, it is strongly recommended that you DO NOT attempt to dive with the regulator until it has received factory prescribed service from an Authorized Aqua Lung Dealer. 4.
T UN C K WISE ) R R E SIS T E LO TE C GR (C EA W E) IS (CO RESISTAN C SS LE ER-CLOCK E 5. Connect the first stage regulator to a fully charged SCUBA cylinder. For mounting instructions, read the Preparation and Setup section of this manual on page 10. 6. SLOWLY open the cylinder valve to pressurize the regulator. Depress the purge button momentarily to ensure that sufficient airflow is provided to blow out any dust or debris which may have entered the second-stage. 7.
9. Inhale slowly and deeply from the regulator several times. The regulator must deliver enough air for you to breathe easily without noticeable resistance. 10. Check to ensure that the submersible pressure gauge is displaying an accurate measurement of the air pressure inside the cylinder. 11. Close the cylinder valve and bleed the air from the regulator by pressing the purge button. Look at the submersible pressure gauge, or your dive computer if it is air integrated.
Diving with an adjustable second stage When you are ready to submerge, turn the regulator adjustment knob on the left side of the regulator all the way “out” (counterclockwise). Then, turn the knob back “in” (clockwise) until the regulator breathes comfortably for you, without being undesirably sensitive. CAUTION: For adjustable second stages sold in the United States, it is normal for the regulator to continuously leak air when the adjustment knob is turned all the way “out” (counterclockwise).
WARNING: Adjusting the regulator to increase breathing resistance will not conserve air. Instead, excessive breathing resistance will actually increase your air consumption, and may elevate the CO2 in your bloodstream to a dangerous level. If you work underwater in an upside down or sideways position, or facing a strong current, you will probably find that you want to turn the adjustment knob back “in” (clockwise), to desensitize the opening effort as needed.
Cold Water Diving WARNING: SCUBA regulators and other equipment have operational limits when used in water colder than 45°F (7°C). If you attempt to dive in cold water without first obtaining the necessary training and preparation of your equipment, you risk serious personal injury or death.
It is possible for icing or freeze-up to occur, even with a regulator that has been specially designed and/or prepared for cold water use. For this reason, it is imperative that you must practice the correct cold water diving procedures, and take special precautions to prevent second-stage icing. This training must include procedures for dealing with regulator freeze-up, unexpected freeflow, and emergency out-of-air situations.
After the Dive NOTE: If fresh water is available, rinse your regulator completely before depressurizing it. This will help to prevent any contaminants from entering sealing surfaces inside the regulator. Removal of the Regulator from the Cylinder Valve (Yoke Connector) 1. Shut off the cylinder air supply by turning the cylinder valve handwheel clockwise until it stops. 2. While observing the submersible pressure gauge, depress the purge button of the second-stage.
Removal of the Regulator from the Cylinder Valve (DIN Connector) 1. Turn off the cylinder air supply by turning the cylinder valve handwheel clockwise until it stops. 2. While observing the submersible pressure gauge, depress the purge button of the second-stage. When the gauge reads zero and airflow can no longer be heard from the second stage, release the purge button. 3. Turn the first stage handwheel counter-clockwise to loosen and remove the first stage from the cylinder valve. 4.
User Care & Maintenance It is important to provide the proper preventative maintenance in order to ensure the best possible performance and maximum life of your Aqua Lung Regulator. The following maintenance procedures should be performed routinely after each use to ensure that the regulator is cleaned, inspected, and prepared for the next use or for storage. 1. Whenever the regulator is removed from the cylinder valve, it is important that the dust cap is installed over the regulator inlet fitting.
a. The preferred method is to attach the regulator to a charged SCUBA cylinder, open the cylinder valve to pressurize the regulator, and thoroughly soak both the first and second-stages. Pressurizing the regulator will effectively prevent the entrance of moisture and/or contaminants into the regulator while it soaks. b.
4. While the regulator is soaking, move the vane adjustment switch on the second stage (if present) back and forth several times from the “MIN” (or “—”) to the “MAX” (or “+”) settings. You may also turn the valve adjustment knob (adjustable models) slightly back and forth—no more than 4 turn. This action will help to loosen any salt or mineral deposits that may remain lodged in the second stage. 5.
7. If the regulator is to be stored for a long period, it is good practice to wipe the hoses and rubber gauge boot with a light film of non-aerosol silicone milk, using a soft cloth. 8. Adjustable models with the VAK feature should be stored with the knob turned all the way out (counter-clockwise) away from the regulator body. This will help to extend the life of the low pressure seat. 9. When the regulator is completely dry, store in a clean equipment box, or sealed inside a plastic bag.
Dealer Inspection & Service 1. It cannot be assumed that a regulator is in good working order on the basis that it has received little use since it was last serviced. Remember that prolonged or improper storage can still result in internal corrosion and/or deterioration of O-ring seals. 2. You must obtain factory prescribed service for your regulator at least once a year from an Authorized Aqua Lung Dealer, regardless of the amount of use it has received.
