USING ENRICHED AIR NITROX

WARNING:

it is imperative that you have received training and hold a certification of

competency in the technique of scuba diving using enriched air nitrox

issued by an accredited agency for such certification. Use of the regulator

by persons uncertified or untrained for this purpose is dangerous and

can result in serious injury or death.

NOTE: The maximum diving depth and the maximum exposure time is

determined by the oxygen content of the mixture.

WARNING:

always be opened slowly.

WARNING:

containing silicone fluid with enriched air nitrox (EAN). Doing so could

result in serious injury or death.

Your regulator was developed for use with enriched air nitrox, provided that the

percentage of oxygen does not exceed 40%. Every regulator is assembled in a

clean workshop, using compatible components and special lubricants. Furthermore,

each regulator is designed to meet adiabatic compression tests to ensure its safety

and compatibility with high oxygen percentages.

If you intend to use your regulator with enriched air nitrox (oxygen percentage not

exceeding 40%), it is essential to ensure that the regulator is kept clean inside.

If you want to use your regulator alternately with breathing air, the breathing air must

be oxygen-compatible or double-filtered and the content of hydrocarbons should not

exceed 0.1 mg/m3. Your Authorized Aqua Lung Dealer can help you determine whether

the supplied breathing air meets these criteria.

In Europe, air in accordance with standard EN 12021 and in the United States, standard

breathing air classified as Grade E, do not meet these criteria. Grade E breathing air or

air in compliance with EN 12021 may contain traces of hydrocarbons, particularly traces

of compressor oil; they are not considered harmful to breathe, but can pose a risk in the

presence of elevated oxygen content.

Over time, a hydrocarbon build-up may occur in valves and regulators. When this

hydrocarbon build-up comes into contact with oxygen-enriched air under pressure, it

may cause a reaction leading to combustion. Therefore, if a regulator was used with

Grade E or EN 12021 breathing air, it is imperative that it get brought to an Authorised

Aqua Lung Dealer for a complete overhaul, including cleaning and degreasing, before

returning it to service for use with enriched air nitrox.

Even if the regulator's second stage components are not exposed to high-pressure enriched

air nitrox, Aqua Lung recommends that the same cleaning and degreasing procedures

should be followed for the entire regulator. This limits the risks of cross contamination

between the regulator's stages and guarantees the cleanliness of the entire regulator.
