ENRICHED AIR NITROX USE (EAN)
WARNING : This chapter contains important information concerning
use with oxygen-enriched air (Nitrox/EAN). Do not attempt to use this
product with enriched air without having entirely read and understood
this chapter. If you do not do this, you risk serious injury or death.
WARNING : Obtain Nitrox Diving Certification. In order to gain a
complete appreciation of the advantages of diving with Nitrox, it is
ABSOLUTELYNECESSARYthatyouundergospecialtrainingand
obtain certification in Nitrox diving from a recognised training agency.
The depth and time limit of the dive depends on the oxygen content of
the Nitrox mixture.
WARNING: The maximum operating depth of your regulator and
exposure times are dependent on the oxygen content of the gas you
are using.
Enriched Air Nitrox Use –
Outside EEC (European Economic Community) Countries
Your Apeks regulator has been prepared for use with Enriched Air Nitrox
(EAN) where the percentage of oxygen in the EAN does not exceed 40%.
This is possible because each regulator is built to a high standard of
cleanliness using EAN compatible components and lubricants. In addition,
each regulator design has passed stringent adiabatic compression testing
to ensure its safety and compatibility with increased percentages of
oxygen.
If it is your intention to use your new Apeks regulator with Nitrox EAN
(O2 not to exceed 40%), it is imperative that you maintain the internal
cleanliness of the regulator (see section on Care and Maintenance). If it
is your intention to use the regulator interchangeably with breathing air,
the breathing air should be oxygen-compatible or “hyperfiltered” where the
condensed hydrocarbons do not exceed 0.1 mg/m3. Your local authorised
Apeks dealer can help you determine whether the breathing air that they
provide meets this criterion.
Regulator Owner’s Manual
............................................................................................
US

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 / Aqualung
specialist centre.

WARNING : These regulators fitted with special connections
should be used only with complementary equipment (tank valves,
tanks, pressure gauges, etc.) designed and prepared for use with
an oxygen-enriched mixture. These items are marked Nitrox/O2.
WARNING: If the regulator that you use is fitted with a yoke or
DIN connection, it is designed for use only with compressed
breathing air (21% oxygen and 79% nitrogen) which meets the
EN 12021 standard. DO NOT USE this equipment with other
mixtures or with gases containing more than 21% oxygen.
Disregarding this rule could result in serious injury or death
caused by fire or explosion.
Every Nitrox/O2 regulator is assembled in a clean workshop, using
compatible components and special lubricants. It is important to
maintaintheinterioroftheregulatorinacleanstate.Breathingair
used in the production of a mixture should be oxygen compatible
and double filtered with a hydrocarbon content not greater than 0.1
mg/m3. Your Apeks / Aqualung technical specialist should be able to
help you determine if the breathing air he/she supplied meets these
criteria.

OVERVIEW OF FEATURES
The Apeks family of regulators consists of different models which
satisfy a wide range of diving interests; from entry level sport diving,
to advanced diving in more demanding and extreme conditions.
By now, your authorised 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 personal diving needs and interests. Be sure to review this
section to learn more about your model’s features and how to obtain
the maximum benefit from using them. The XTX range offers two
features unique to XTX. The option for either left or right hand hose
configuration and the Diver Changeable Exhaust system (DCE).
Second Stage Hose Configuration
Apeks XTX regulator range can be dedicated to either left or right
handed use in conjunction with the RVS system (see page 11). The
hose routing can be altered from right hand to left or from left hand
to right by your Authorised Apeks / Aqualung Dealer. This is an
extremely useful feature offering much greater flexibility for personal
kit configuration.
Right Hand Left Hand
Note: This conversion must only be performed by a factory
trained Authorised Apeks / Aqualung Service Technician who
is employed by an Authorised Dealer. Contact your Authorised
Apeks / Aqualung Dealer for further information on this feature.
Disassembly, adjustment or repair must not be attempted by
persons who are not factory trained and authorised by Apeks /
Aqualung.

Diver Changeable Exhaust system (DCE)
The Diver Changeable Exhaust (DCE) offers the choice of either a
compact lightweight system or a longer exhaust diffuser. DCE can be
configured to prevent virtually any bubble interference from obscuring
the diver’s view.
The exhaust diffusers can be easily and very quickly changed by
sliding and locking the preferred set into place. Divers can now
configure their own regulator exhaust diffusers for individual dive
conditions or requirements.
Bypressingthesecuringbuttoninthecentreoftheexhaustdiffuser
and at the same time sliding the diffusers apart, they can be removed
quickly and easily.
To attach an alternative set of exhaust diffusers, align the slide
locations as shown and slide each side into place, taking care that
the exhaust diffusers are located securely. When the two diffusers
meet, squeeze them together until an audible “click” is heard from the
retaining button.
1. First, gently press the button located in the centre of the exhaust
diffuser.
2. Then slide both exhaust diffusers apart, whilst keeping the button
depressed.
PRESS
HERE
CAUTION! Do not use any tools to aid the
removal of the exhaust diffusers.

CAUTION! Ensure
location grooves are free
from dirt and debris.
3. Refitting the exhaust
diffusers is carried out
by sliding ONE diffuser
at a time onto the case,
once both diffusers
are located on the
case, squeeze the two
diffusers together until
you hear an audible
“click”.
Note: The removal
and refitting of the small exhaust diffusers is carried out in
exactly the same way as the large exhaust diffusers. If the
exhaust diffusers do not securely clip together then they may
become detached and lost. (If required, exhaust diffusers may be
purchased separately).
WARNING: Do not attempt to use tools to remove or attach the
exhaust diffusers. After the removal of the exhaust diffusers, care
must be taken to prevent damage to the exhaust valve. Do not attempt
to poke, pull or touch the exhaust valve or surrounding area with
any tools. If damage to this part or surrounding area occurs then this
could cause your regulator to leak, causing serious malfunction or
even personal injury. Care must be taken when securing alternative
sets of diffusers, do not apply excessive force as damage may occur
to the diffusers, exhaust valve or surrounding area.

External Second Stage Adjustments
External adjustment features offer many advantages, including
the ability to adjust your second stage regulator’s sensitivity as
your diving conditions change. This allows you to maintain peak
performance throughout every dive, or to desensitise your regulator’s
opening effort at times when you are not breathing from it.
Integrated Venturi Switch
Apeks second stages are equipped with a diver controllable venturi
system. This system is known as the integrated venturi system (IVS)
switch or Reversible Venturi System (RVS) on the XTX range of
second stage regulators. This switch allows the diver to control the
venturi assist to reduce sensitivity to free flow at the surface and
provide the maximum airflow at depth.
Whilst diving, set the switch to plus (+) to achieve maximum venturi
assistance for easier breathing.
To prevent the second stage from free-flowing, however, you should
set the IVS/RVS to the MIN(–) setting during entry or while swimming
on the surface.

Switch.
CAUTION: Do not use

US
14
Inhalation Resistance Control Knob
Some second stage models are equipped with an additional
adjustment, which controls inhalation resistance.
This control knob, located beside the IVS/RVS switch, adjusts the
amount of effort required to start the air flow at the beginning of the
inhalation cycle. As it is turned “in” (clockwise), the opening effort will
increase. This will make the second stage less sensitive to sudden
changes in ambient pressure. Turning the knob “out” (anti-clockwise)
will decrease the opening effort to make breathing easier.
This adjustment is particularly useful at deeper depths, or in variable
conditions that affect the opening effort of the second stage, such as
strong currents or while using a diver propulsion vehicle (DPV). You
can use the inhalation control knob to tune your regulator to maintain
its peak performance throughout the course of your dive, or you can
leave it set in its mid-range position and dive with it as you would any
non-adjustable second stage.
For more information on using these adjustments, refer to the section
titled, Diving With Your Regulator, on page 31.

Egress Second Stage
The Egress is a low
profile second stage
suitable for use in all
diving conditions, and
can be used either
way up due to its side
exhaust and hose layout.
Therefore the diver
can use the second
stage with the hose
routed from either the left
or right depending on personal
preference and setup requirements.
The Egress second stage incorporates a
pneumatically balanced valve system which
is primarily aimed for use as an alternative air source second stage
although can still be used successfully as a primary second stage.
The Egress also incorporates the patented thermo-dynamic heat
exchanger technology which makes it suitable for diving in water
temperatures below 10ºC, see page 33.

STATUS
STATUS..... REASSURANCE THAT YOUR REGULATOR IS AT ITS
OPTIMUM
Safety first
Safety is of paramount importance to Apeks. The Status electronic
first stage gives divers the option, for the first time ever, to visually
check the condition of the first stage of the regulator using an
integrated LCD display before actually commencing a dive. A correct
medium pressure is essential if your regulator is to perform as it
should.
The condition of the first stage is assessed by an internal micro-
electronic computer, which checks the medium pressure during the
initial opening of the cylinder valve. Information is displayed on an
LCD screen protected and housed in the dry sealed chamber.
Micro-electronics are both extremely accurate and reliable. Apeks
has developed the micro-electronics of the Status specifically for the
extremeunderwaterenvironmentofSCUBAdiving.

Regulator Owner’s Manual
............................................................................................
US

Servicing
Another unique safety feature of the Status regulator is that it
monitors the usage, in hours and calendar months, from when the
regulator is first used or last serviced. The diver is informed that the
first stage requires servicing by a flashing “SVC” indicator on the LCD
screen. This will occur when the regulator is initially pressurised. To
keep your regulator in premium condition it is vital that this is regularly
and correctly serviced. You will know by quick examination of the
display that your medium pressure is OK.
Understanding the Status
What is medium pressure?
All first stage regulators are designed to reduce the very high cylinder
pressure down to a more controllable medium or interstage pressure.
This medium pressure which is the driving force of the regulator, is
supplied to the second stage which in turn controls the supply of gas
to the diver. knowing the medium pressure is within its ideal operating
range, gives the diver full confidence that the first stage is at its
optimum before every dive.
