POSEIDON XSTREAM User manual

USER MANUAL :: ENGLISH
:: XSTREAM

Our objective is that the equipment you are wearing should not be noticeable, instead it should be at one with the experience and give
you total freedom to achieve what every diver dreams about, the ultimate dive. To be at one with the water. To have full control and at
the same time feel the weightlessness when, meter by meter you descent into a world of your own.
Nothing shall disturb your concentration. No wheels or levers that need adjusting. No regulators that resist your breathing when you have
reached your target depth. No suits that limit your freedom of movement or get damaged at the slightest encounter.
This vision has accompanied Poseidon since the legendary diving enthusiast and engineer, Ingvar Elfström started the company in the
late 50’s. The same ideas motivate us now.
The name Poseidon represents constant development and improvement of diving equipment where everything is positioned correctly
and everything functions, even in the most extreme situations.
Products developed in cold Scandinavian waters that are among the toughest you can dive in. If they work here, they will work any-
where. Poseidon’s devoted followers are convincing proof of that. Thank you for your confidence.
Yours faithfully

USER MANUAL :: ENGLISH :: 5XSTREAM
FUNCTION
Although the regulator is functional with
pure oxygen and has excellent breathing
characteristics down to 200m (656 ft), the
usage is restricted by human limitations, or,
by limitations set out by the dive training
organisation, whichever is lower.
Poseidon only warrants the regulator performance as spe-
cified herein, and cannot be held responsible for improper
preparations, incorrect gas mixing and planning, or diving
beyond individual medical, psychological and physical limi-
tations.
Limitations of use:
Xstream Deco, Oxygen and Duration models no higher oxy-
gen content than 99,95% by volume
Xstream Deep models only for use with air or Trimix with a
maximum oxygen content of 21%, and a maximum Helium
content of 77%
Xstream Dive and octopus only for use with air and a maxi-
mum depth of 50 meters.
Maximum depth never more than 200 meters (656 ft), but
normally limited by medical effects of the gas.
The oxygen partial pressure must normally not exceed 1.4
bar (20.3 psi), under the foreseeable maximum diving depth.
Only if established oxygen exposure tables are strictly adhe-
red to, and a responsible organisation is planning dives with
increased exposures, elevated levels can be accepted for a
shorter period of time.
The oxygen partial pressure must never be lower than 0.2
bar (2.9 psi), under the foreseeable minimum diving depth.
GENERAL SAFETY REGULATIONS

:: 6 XSTREAM USER MANUAL :: ENGLISH
FUNCTION
The nitrogen partial pressure must not exceed 3.2 bar (46.4
psi), under the foreseeable maximum diving depth.
Inhaling cold gas and exhaling warmed gas, represents
energy losses of the human body (thermal imbalance, hy-
pothermia). This effect increases with increasing depth and
can result in a sudden unconsciousness. Diving to extreme
depths this effect must be considered, calculated and plan-
ned for and preventive actions must be taken, such as pro-
per thermal protection and pre-heated gas
Xstream is for unlimited use in water temperatures from
water freezing temperature tice +1°C to +50°C (122°F). The
freezing temperature depends on salt content.
Diving with gas blends other than air, or deeper than 18 m
(59 ft), or in overhead environment, requires special train-
ing regarding practices, equipment, physical and medical
understanding.
This manual assumes the reader has some basic knowledge
in those respects.
Diving is a strenuous physical activity. Its difficulty may be
increased by conditions such as cold water, poor visibility,
hard work, and increased depth. Always try to exercise pru-
dent judgement when determining whether or not to dive.
Never dive when tired or in poor health.
Diving deeper than 50m (164 ft) using gasses other than
air is more demanding on the equipment. Most equipment
on the market is only approved for use within EN 250 limits.
Although Xstream Deep is certified to 200m (656 ft) depth
and Xstream Deco is for use with pure oxygen, you must al-
ways make sure all of your equipment is suitable.
Do not use gas mixtures containing Helium for dry suit infla-
tion. Helium has very low insulating properties, and contri-

butes to a more rapid cooling of the body.
Preferably Argon shall be used, but must
never be inhaled. Insulating or actively hea-
ting of the body surface has very little effect
on the hypothermia described above.
WARNING!
Xstream Oxygen, Xstream Deco and Xstream Duration
must be used exclusively with Nitrox or Oxygen and should
be kept O2 clean at all times. If a Oxygen, Deco or
Duration regulator is contaminated or used with a
contaminated fill then the regulator must be O2 cleaned by
a certified Poseidon O2 technician.
WARNING!
The Xstream regulators are not designed to be breathed
up on by more then one person at a time. If you configure
your Xstream regulator for more then one diver to breath
from it at a time, the cold water performance may not meet
minimum safety standards.

FUNCTION
Oxygen alert and oxygen handling recommendations in this
manual applies to all parts and products intended for use
with greater than 21% oxygen by volume.
All accessories and other SCUBA equipment connected to
Xstream must be approved by the manufacturer for use with
the same oxygen content which is used with the Xstream.
Cylinder valves must always be opened carefully and slowly,
to avoid pressure shocks.
Oxygen can cause serious medical effects or even death
if used incorrectly. Use recognised tables for oxygen
exposure.
Xstream Oxygen EN 144-3/Deco/Deco EN 144-3 is approved
for oxygen service directly from the box, i.e. it is cleaned
to NASA Specification [1] Cleaning test Level 100 (particle
contamination) and NVR levels less than ASTM G63 Level C,
<50 mg/m2 (hydrocarbons).
Xstream Duration/Duration EN 144-3 is cleaned to the same
level as Xstream Deco Regulators and all other equipment
for oxygen service must be identified as such

USER MANUAL :: ENGLISH :: 9XSTREAM
FUNCTION
PRODUCT DESCRIPTIONS
The Xstream regulator models have been
developed based on experience gained from
deep diving, cave diving, wreck diving and
cold water diving.
The different types all share some common
requirements on safety through functiona-
lity, simplicity and performance.
XSTREAM 2:ND STAGE
A number of features greatly improve safety and ease of
use:
If debris has degraded the function of the exhalation check-
valve, it can easily be reached and corrected by just twis-
ting off the diffuser. It is the only part which needs to be
disassembled, and if it gets lost during the operation, the
regulator will continue to function but must only be used for
immediate ascent.
In case of a malfunction in the 1st stage causing excessive
intermediate pressure, the safety valve integrated in the
1st stage will bleed off the excessive gas. This system both
indicates to you that something is wrong so that you can
take action, and because of the up-stream servo-valve tech-
nique, allows the regulator to continue to breath normally.
(conventional downstream regulators are likely to free-flow
in such a situation)
Integrated surgical hose fixing points safely secures the
regulator to the diver, but in an emergency allows a distres-
sed buddy to retrieve the regulator without undue stress to
the diver.
The dead air space is low at just 49.5 ml (3 in3) making CO2

:: 10 XSTREAM USER MANUAL :: ENGLISH
FUNCTION
figures (hypercapnia) minimal. Inhalation resistance is in-
credibly low and unaffected by depth and breathing pattern
Because of the unique Poseidon valve technology, there is
no need for external adjustments.
Xstream is fitted with the new ergonomic mouthpiece Posei-
don AIR, with asymmetrical lugs for the most comfortable
bite.
All diaphragms are protected so that a strong current or
using a scooter or tug does not affect either inhalation or
exhalation.
A minimal number of moving parts, coupled with
thermodynamic engineering, ensures the safe use in an
extremely cold environment.
XSTREAM 1:ST STAGE
The first stage is a balanced rolling diaphragm ball valve
producing extreme leaktightness.
Conventional designs are sensitive to wear, misalignment,
and manufacturing precision. A ball always finds its correct
place.
Combined with the 2nd stage, the enormous capacity of the
1st stage make the regulator meet the EN 250 breathing
performance requirements even at as low as 16 bar (232
psi) cylinder pressure. This means that you gain an extra 34
bar (493 psi) of gas compared to most other regulators!
The Xstream construction requires less o-rings than any
other regulator. Except for sealing the blind screws (3-4),
there is just 1 sealing o-ring (semi-static) in the bottom-
mounted versions and 2 in the side mounted.
The hose routing is developed to be optimised for a redun-
dant system, using two regulators. The HP ports are positio-
ned to accommodate the use of gas monitoring computers
e.g. first stage mounted HP sender/receive units.

FUNCTION
POSEIDON T.D.A
Xstream has a built-in Poseidon T.D.A,
ThermoDynamic Anti-freeze, which requi-
res no maintenance. It is always there,
doing the job. It is thermodynamically pro-
tecting the parts which must not freeze.
It is identified by the large slots in the
cover, allowing the heat energy of the wa-
ter to reach the spring. The cold from the inside is conse-
quently insulated from the spring, via an insulation barrier
and insulating diaphragm. It is constructed without com-
promise to any detail to prevent cold reaching the sensitive
area. Using Poseidon T.D.A, a regulator can free-flow air in
fresh water of 0ºC (32ºF) for at least 10 minutes and after-
wards still be completely unaffected
DEEP / DEEP90 1:ST STAGE (TRIMIX, AIR)
All materials in Xstream Deep are chosen and tested to be
optimised for Helium and high flow. This requires special
attention to leak tightness, since Helium gas has such a
low density.
All o-rings are of the highest Nitrile quality, and rated for
use down to -40ºC (-40ºF)
Deep 1st stage comes in two different versions. One side
mounted and one bottom mounted. Both versions are certi-
fied to 200m (656 ft) depth, and colour-coded black which
in most countries represents a bottom gas mix.
The bottom mounted Deep was discontinued in 2005
Deep must never be used with an oxygen content > 21%,
or a helium content > 77%.

FUNCTION
DECO / OXYGEN 1:ST STAGE (OXYGEN, EAN, AIR)
O4 stands for oxygen engineered, oxygen compatible, oxygen
clean and oxygen approved. Xstream Deco is O4. It is not just a
viton configured air regulator, but in detail engineered for pure
oxygen.
The Xstream Deco is made as a bottom mounted version. The
connection stem is sealed with a pure copper washer sintered
onto the filter.
It has been tested for 360 bar (5221 psi) adiabatic compression
oxygen shocks of less than 20 ms (heated to 60°C/140°F) ac-
cording to EN 738-1. To make the test even more severe than
required, it is tested with 99.95% purity of oxygen.
Directly from the box, it is cleaned to NASA Specification [1]
Cleaning test Level 100 (particle contamination) and NVR levels
less than ASTM G63 Level C, <50 mg/m2 (hydrocarbons).
The Xstream Oxy90 1st stage is only used on the Mk VI Discovery
Rebreather.
The Xstream Deco was discontinued in 2005.
DURATION/DURATION EN 144-3 1:ST STAGE (EAN, AIR)
Duration shares the performance and specifications from Deco,
but is identified by colour, and approved for use with gas mixes
up to 99,95% oxygen
If you prefer the 5 IP ports and such a configuration of your
equipment and you plan on useing mixtures greater than 50%
- Duration is the regulator for you.
The green colour coded Duration is offered for your safety at the
dive site and during the dive, avoiding the risk of mixing up re-
gulators for different gasses
The side mounted Duration model is available in EN 144-3 con-
figuration.
The bottom mounted Duration was discontinued in 2005.

FUNCTION
DIVE90 1:ST STAGE (AIR)
Dive shares the performance and specifications
from the other Xstream 90 models. It is identified
by the chrome plated T.D.A. top and the number of
outlets: 5 low pressure and 2 highpressure.
Xstream Dive is delivered with a 70 cm hose, but
all hoses available for the Xstream regulator also
fits the Xstream regulator.
The Dive90 was discontinued 2005 and replaced with Deep90
XSTREAM LP HOSES
All Xstream hoses are made of high quality SBR/NR, and are av-
ailable in different lengths. For deep dives or in particularly cold
conditions a long hose 2.15m (7 ft) has the benefit of warming the
gas by as much as 12°C (22°F) under certain conditions.
Using a long hose requires some basic knowledge in its use and
routing, to take the full advantages.
Poseidon does not recommend the use of hose protectors on Po-
seidon IP hoses.
Hose protectors have been shown to mislead the user to neglect
the necessary pre-dive hose inspection. Therefore, Poseidon ho-
ses are fitted with wear preventing end crimps, which in addition
can be inspected for the full engagement of the hose to the insert
at any time through the inspection hole.
On Xstream specific hoses (article no 4680-XXX) the hose end at
the 2nd stage includes the safety valve. As a visible indication of a
fault, the excessive gas will bleed to the ambient environment.
The hose is available in the following lengths as standard
2.15m (7ft.)
1.50m (4.9 ft)
0.90m (3 ft)
0.70m (2.3 ft)
Xstream Dive90 1st stage

:: 14 XSTREAM USER MANUAL :: ENGLISH
HOW TO USE
USAGE
First time mounting the hose of the length you have cho-
sen, start with unscrewing the blind-screw (5mm allen-key)
where you want the 2nd stage. Be careful not to contamine
either the open port or the hose end. Screw the hose in place
using a 13mm box spanner. Continue with attaching the 2nd
stage. Just screw the nut over the 2nd stage housing, and
secure it firmly by hand.
MOUNTING THE HOSE
If you have a Oxy, Deco or Duration model, be absolutely
sure not to touch the o-ring or other inner connection areas
with your fingers, since fingerprints are a combustible con-
tamination.
OXYGEN ALERT!
PRE DIVE
The procedure described below only describes the manner
in which the regulator is assembled, and does not replace all
of the various procedures you have learned in your diving
training program.
Xstream must always be used with minimum the following
SCUBA equipment :
- Compressed gas cylinder(s) conforming to natio-
nal regulations
- Frame or holding device for the cylinder(s) with
the possibility to mount the harness
- A safety system, including at least one of the follo
wing:
- A submersible pressure gauge
- A reserve valve
- An active low pressure warning device
1) Always check the gas-content of the cylinder before at-
taching the regulator.

USER MANUAL :: ENGLISH :: 15XSTREAM
HOW TO USE
2) Before attaching the regulator, carefully
open the cylinder valve, using gas flow to
clear the outlet, then close the valve. Never
direct the gasstream to bare skin or clothes
(porous materials)
3) Remove the protective cap on the first st-
age. Check that the O-ring on the regulator’s
connection is intact and clean, then mount
the regulator on the cylinder valve. Turn the handwheel/
yoke-knob until you feel that the regulator is securely fast-
ened.
Inspect the o-ring, and make sure it is absolutely free from
particles and/or grease. Do not touch the o-ring. Grease and
particles can cause a fire.
4) Slowly open the cylinder valve all the way, then turn the
knob back half turn. When the 2nd stage is pressurised and
the servo mechanism engages a maximum of 3 litres of gas
vents from the 2nd stage.
Slow opening of the cylinder valve is the best way to protect
the system from compression shocks. Rapid openings repre-
sents the highest risk for fire due to compression shock. To
ensure a slow opening it is good practice to use both hands,
one on top of the other.
Always open the cylinder, and isolator valves if used, first
fully and then a 1⁄2 turn back. Partly opened valves in-
creases the pressure drop over the valve and can reduce
the performance. On some brands, valves that are almost
closed can even shut off during a dive due to internal flexing
of materials.
5) Press a few times on the purge button on the second
stage so as to blow out possible debris.
6) Check the pressure gauge to see that the tank is full,
OXYGEN ALERT!
OXYGEN ALERT!

:: 16 XSTREAM USER MANUAL :: ENGLISH
HOW TO USE
whilst purging, by watching the almost zero deflection of
the needle this indicates that the air is flowing correctly
with no restrictions.
7) Test breathe through the regulator and the octopus. If
the gas smells or tastes bad do not dive with it.
Tip! You can test the regulator’s correct setting by partly
immersing the 2nd stage in water, see picture. The servo
valve should crack open when the regulator is immersed in
between the two positions shown.
Tip! At dives where the water conditions are very cold
or there is an apparent risk for hypothermia, i.e. at
Trimix dives or water temperatures < 10ºC (50ºF), it is
recommended to use the surgical cord around the neck for
the regulator being used. The mouth region can become
numb from cold and you risk loosing the regulator.
DIVING
What is most distinctive about the Xstream is that it is easy
to use – there aren’t any valves or switches to change the
flow of gas, reducing breathing performance, etc. You can
leave the function and performance of the regulator in our
hands and concentrate on what you want to do - dive.
If on any occasion the gas tastes bad, especially the taste
of chlorine, always immediately switch to another safe gas
source. Bad taste can be a sign of an internal combustion,
and lethal gasses can be present.
If on any occasion the safety valve starts bleeding, there
is a 1st stage failure. Due to the construction, you can still
breathe normally from the regulator. To avoid excessive
use of gas, if possible switch to another gas source.
Ascend, never dive with a malfunctioning unit
WARNING!
OXYGEN ALERT!

USER MANUAL :: ENGLISH :: 17XSTREAM
MAINTENANCE
The regulator should always be rinsed while
it is still mounted on the tank.
The regulator should be under pressure, i.e.
mounted onto the cylinder, otherwise wa-
ter can enter either the first or the second
stage and cause the build up of ice during
your next dive!
1) The regulator should be rinsed in fresh water after every
dive so as to avoid salt crystal formation around the func-
tional parts.
2) After rinsing, close the cylinder valve and purge the re-
gulator.
3) Unscrew the regulator from the tank. Check that the pro-
tective cap is free from water and debris, then mount the
protective cap onto the connection.
The regulator should not be stored in direct sunlight and/or
at high temperatures. Make sure it is never subjected to
mechanical shocks or impacts.
Never unscrew a pressurised regulator from the tank. This
can create a jet of gas over the o-ring and cause a fire.
Never use the 1st stage housing to unscrew the regulator
from the tank. This can fully or partly unscrew the connec-
tion stem from the housing, and create a future hazard. Al-
ways use the handwheel.
Do not smoke in an area where oxygen is present. Never
lubricate the regulator and keep hands and tools clean and
absolutely free from grease.
