User manual POSEIDON THE PLATFORM

[. . . ] To have full control and at the same time feel the weightlessness when, meter by meter you descent into a world of your own. 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. [. . . ] first stage mounted HP sender/receive units. Xstream 90° Model Patented :: 10 XSTREAM FUNCTION USER MANUAL :: ENGLISH figures (hypercapnia) minimal. Inhalation resistance is incredibly low and unaffected by depth and breathing pattern Because of the unique Poseidon valve technology, there is no need for external adjustments. FUNCTION Xstream 1st stage TDA system (shown in green) POSEIDON T. D. A Xstream has a built-in Poseidon T. D. A, ThermoDynamic Anti-freeze, which requires no maintenance. It is identified by the large slots in the cover, allowing the heat energy of the water to reach the spring. The cold from the inside is consequently insulated from the spring, via an insulation barrier and insulating diaphragm. It is constructed without compromise 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 afterwards still be completely unaffected DEEP / DEEP90 1:ST STAGE (TRIMIX, AIR) Xstream Deep90 (4691-BK) Xstream Deep (4690-BK) 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. Both versions are certified 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 WARNING! Xstream Deep90 (001-47 / 0100-000) Deep must never be used with an oxygen content > 21%, or a helium content > 77%. USER MANUAL :: ENGLISH XSTREAM :: 11 Xstream Deco (4960- WE) O4 stands for oxygen engineered, oxygen compatible, oxygen clean and oxygen approved. It is not just a viton configured air regulator, but in detail engineered for pure oxygen. The servo valve should crack open when the regulator is immersed in between the two positions shown. 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 OXYGEN ALERT! WARNING! :: 16 XSTREAM HOW TO USE USER MANUAL :: ENGLISH whilst purging, by watching the almost zero deflection of the needle this indicates that the air is flowing correctly with no restrictions. MAINTENANCE AFTER DIVE The regulator should always be rinsed while it is still mounted on the tank. [. . . ] stop within 3 litres of air is used to en1-2 se- gage the servo-mechanism conds? If no, the cracking pressure is too low, which increases the risk for free-flow :: 24 XSTREAM USER MANUAL :: ENGLISH MISCELLANEOUS MISCELLANEOUS OXYGEN STATEMENT In diving operations, the use of oxygen is essential for the human metabolism. In addition, oxygen concentration levels greater than in air, can improve safety, especially but not only, by lowering the risk for DCS and Nitrogen narcosis. The Poseidon Xstream Deco/Oxygen is approved for use with gaseous oxygen up to 99. 95 % purity at maximum 300 bar supply pressure and a maximum gas temperature of 60°C. The Poseidon Xstream Duration90/Duration/Duration EN 144-3 is also approved for use with gaseous oxygen up to 99, 95 % purity at maximum 300 bar supply pressure and a maximum gas temperature of 60°C for the Xstream models. Regular maintenance, servicing and cleaning is a prerequisite for keeping the risk as low as possible. [. . . ]
