IMPORTANT SAFETY INFORMATION PLEASE READ CAREFULLY
WARNING
This regulator is intended to be used only by those competent, trained and certied by
a nationally recognized SCUBA training agency. This manual is not a substitute for such
training. Diving without such training is extremely hazardous and could result in serious
personal injury or death.
NITROX (EAN) USE
Our regulators have been independently lab tested to meet the stringent ASTM G-175 requirements
for positive ignition testing. Each Atomic Aquatics reg model has been tested and passed the
ASTM G-175 requirement before we certify it as SAFE for EAN. Note: The TFX regulator may
be used interchangeably with air or EAN mixes of up to 40% oxygen concentration at 3500 psi
maximum. They need not be dedicated for EAN use, provided that they are used with air or EAN
mixtures that meet minimum dive industry purity standards.
WARNING
NITROX (EAN) USE — ALL MODELS
IMPORTANT NOTICE - READ BEFORE YOU USE THIS REGULATOR
These regulators have been assembled, cleaned and made compatible for enriched air
Nitrox (EAN) to a maximum 40% oxygen concentration at a maximum pressure of 3500
psi. They do not require additional cleaning or servicing.
If the regulator becomes grossly contaminated with dirt, oils, or greases from any source,
have the regulator re-cleaned before using it again with EAN. Do not use silicone or
hydrocarbon greases in or around regulators being used for EAN Nitrox or oxygen mixes.
Do not under any circumstances use these regulators with pure oxygen or any gas
mixture exceeding 40% oxygen. Failure to comply with the above warnings could cause
serious personal injury or death from re or explosion.

WARNING
COLD WATER USE
For diving in extreme cold waters below 50°F (10°C), we recommend having the rst
stage sealed with the installation of the optional anti-freeze kit (standard in TFX,T3, T2x,
ST1 & M1). This is a rubber sleeve that ts over the ambient chamber ports of the rst
stage to prevent icing of the rst stage. This is a factory or dealer installed item, as it
requires special tools and disassembly of the rst stage for lling of the chamber with a
special low temperature lubricant.
DIN CONNECTIONS
For use with cylinders having DIN style
valves (typically at pressures above 3000 psi),
a 300 BAR DIN connection is available.
It replaces the yoke connection and can
be ordered as standard from the factory or
as an option installed by the dealer.
TFX with DIN
Connection
You now own one of the nest and most unique regulators available. . . regardless of price. The TFX
forges a new Titanium standard as our signature regulator, providing you unprecedented reliability
and performance.
The TFX name refers to Titanium Front Exhaust. This diers from conventional second stages
which are congured with an exhalation diaphragm in the front and an exhaust valve in the rear.
The placement of the inhalation diaphragm and exhaust valve centered in the front of the regulator
oers some unique advantages for improved breathing and dryness.
The front exhaust in not a new concept. Developed over 40 years ago, we have taken a fresh look
at this unconventional design to bring you the ultimate "connoisseurs" breathing regulator with a
natural and sophisticated air delivery. The TFX includes many of the iconic features and specialty
materials found in all Atomic Aquatics regulators.

SEAT SAVING ORIFICE:
This new orice design dramatically prolongs the life of the rubber seat. Seat wear is the number one
cause of regulator leaks and performance degradation over time. The rst and only adjustable dynamic
orice is pressure energized and only contacts the rubber seat when the regulator is being used. The
orice is constructed of corrosion-free titanium.
LOW FRICTION BEARING SURFACES:
The demand valve is tipped with low friction cap that provides smooth, silky inhalation, even after
millions of cycles due to this proprietary reinforced polymer insert at the pivot point of the lever.

HOSES:
Your regulator was function tested and is ready for use from the factory. You will need to install
your high pressure gauge, instruments and low pressure accessories such as inators. If you are in
doubt on how to do this, see your Atomic Aquatics professional retailer for assistance.
LOW PRESSURE HOSES: (LP thread size 3/8"-24)
Your regulator has either 5 low-pressure (LP) ports on the swivel end of the rst stage
(T3, T2x, ST1, M1, B2) or 7 low pressure ports (Z2/Z3) in a xed orientation. Choose the ports
that give you the best orientation for your particular set-up. The LP port plugs can be removed by
unscrewing with a 5/32" (4mm) hex wrench. Install the LP hoses into the port and snug up with a
wrench. Do not overtighten as this will not improve the seal and may damage the threads.
HIGH PRESSURE HOSES: (HP thread size 7/16"-20)
Your regulator has 2 high pressure ports (marked HP) on either side of the body. The HP ports and
plugs are larger in size than the LP plugs. Remove the plugs with the same hex wrench and install
the high pressure gauge hose into the high pressure port and snug it with a wrench.
SYSTEM SET-UP
CAUTION
Do not assemble any low pressure hoses to the HP port of the rst stage. The hose
could rupture and could cause serious personal injury. Do not assemble the high
pressure gauge to the low pressure port or the gauge will not indicate tank pressure.

OPERATION:
This front cover has a soft exible frontal surface that is easy to depress to purge. The closed frontal
surface reduces the chance of free ow that might occur if in a strong current, such as might be
encountered in caves or open water. The ambient water ports of the second stage are directed to the
sides, where a frontal current will not upset the regulator diaphragm.
RAPID ADJUSTMENT VENTURI CONTROL:
The quarter-turn manual override adjustment allows quick detuning for surf entries, jumping o a boat,
octopus use or other special situations. The knob rotates the Venturi nozzle towards or away from
the mouthpiece opening. Pushing it forward results in maximum ow during diving; pulling rearwards
reduces sensitivity and chances of free owing. Note that this control reduces overall ow yet does not
change the inhalation eort or make it harder to breathe.

CAUTION
DO’S AND DON’TS:
Do set up your equipment carefully before each dive and check your entire system for signs
of damage, loose hose ttings, and air leaks. Make sure the yoke knob or DIN connection is
hand tight before turning on your air supply. Purge the regulator and take a test breath before
entering the water.
Do not use your regulator if you notice any problems or malfunctions. Return it to the factory
or authorized dealer to have it checked or repaired.
Do not pick up your tank by the hoses. You may damage them or work loose a connection
that could lead to loss of air.
POST DIVE CARE:
A simple fresh water rinse after every dive to clean the regulator of salt, sand or dirt is all that is
required. Do not rinse or soak the regulator in solutions containing bleach as this can permanently
damage the silicone rubber components. Dry or blow o any water in the rst stage dust cap and
t it in place. Rinse through the ambient ports of the rst stage (unless tted with an anti-freeze kit)
and through the mouthpiece of the second stage. Rinsing is particularly important with the chrome
plated brass rst stages (M1, B2, Z2/Z3) to maintain it in top condition and keep the chrome
looking attractive. Avoid soaking the regulator unpressurized, as water may enter the second stage
and rst stage mechanism. If the second stage is purged when it is rinsed or soaked, it is a good
idea to re-connect the regulator to a tank and blow out any water that may have entered the rst or
second stage.
Store the regulator away from direct sunlight to prevent fading and deterioration of the rubber and
plastic parts. Keep away from excessive heat, humidity or insects.
REQUIRED SERVICE
The major service interval for the Atomic Aquatics regulators is once every three years or 300
dives*.
