[. . . ] :: XSTREAM USER MANUAL :: ENGLISH Poseidon XSTREAM for XSTREAM use Welcome, new Poseidon divers. Here at POSEIDON we are very pleased that you have chosen one of the world's foremost diving regulators. POSEIDON has been developing regulators for divers since 1958. Professional divers, military divers, and techdivers choose POSEIDON equipment because of the high demands they place on our products - the same demands you have! [. . . ] Therefore, Poseidon hoses 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) USER MANUAL :: ENGLISH XSTREAM :: 13 MOUNTING THE HOSE First time mounting the hose of the length you have chosen, 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. Just screw the nut over the 2nd stage housing, and secure it firmly by hand. OXYGEN ALERT! 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 contamination. 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 national 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 attaching the regulator. :: 14 XSTREAM HOW TO USE USER MANUAL :: ENGLISH USAGE 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 stage. 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 fastened. OXYGEN ALERT! Inspect the o-ring, and make sure it is absolutely free from particles and/or grease. 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 represents 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 increases 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, XSTREAM :: 15 OXYGEN ALERT! USER MANUAL :: ENGLISH 7) Test breathe through the regulator and the octopus. If the gas smells or tastes bad do not dive with it. Tip! [. . . ] Poseidon has developed and verified a servicing and cleaning method, which guarantee acceptable levels of contaminations. Poseidon can not be held responsible for the effects of other un-verified cleaning and servicing methods. Failure to adhere to these mandatory requirements transfers the responsibility to the owner. Poseidon will continue to develop products and components which further readuses the risks involved with oxygen use. [. . . ]
