Regulator Owner's Manual

............................................................................................

Standard compressed breathing air meeting the EN 12021 standard, often

referred to as Grade E in the United States, does not necessarily meet this

criterion. Grade E or EN 12021 breathing air may contain a certain level of

hydrocarbons, including traces of compressor oils that while not considered

harmful to breathe, can pose a risk in the presence of elevated oxygen

content. Passing hydrocarbons through a valve and regulator creates a

cumulative effect where the hydrocarbons build up over time along the

internal passageways of the equipment. When these hydrocarbons come

into contact with high-pressure oxygen enriched air, they can pose a very

real hazard that can lead to combustion. Therefore, if a regulator has

had use with Grade E or EN 12021 breathing air, it should be returned

to an authorised Apeks dealer for overhaul service including oxygen

cleaning, prior to being put back into nitrox service. Although second stage

components are not exposed to high pressure EAN, Apeks 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.

Enriched Air Nitrox Use – Inside EEC (European Economic

Community ) countries EN 1443-3 and EN13949

In CEE countries, diving with Nitrox/O2 is controlled by Standards EN

144-3 – Respiratory protective devices - Gas cylinder valves - Part 3:

Outlet connections for diving gases Nitrox and oxygen - and EN 13949

– Respiratory equipment - Open circuit self-contained diving apparatus for

use with compressed Nitrox and oxygen - requirements, testing, marking.

NOTE : The maximum depth of the dive is determined by the type

of mixture used.

NOTE : Apeks offers a range of regulators designed and manufactured

specially for use with oxygen-enriched mixtures, over 21% and up to

100% oxygen. This range has been certified according to the EN 144-3

and EN 13949 standards and meets the requirements of the adiabatic

compression tests. They have received CE certification for this type.

For further information on this range, contact your Apeks

specialist centre.
