WARNINGAlways check that the first stage to which theSORIUSOCTO is connected is a SEACSUB product; if it is not so, verify that the intermediate pressure set is comprised between 9 and 10.5 bars.Failure to respect this recommendation mayimpair the 2nd stage performance and cause serious accidents. The main body is made from synthetic resin WARNINGUse only standardised thread pressure gauge. Do not use any type of adapter between the 1st stage and the high pressure hose connection. The SORIUS regulator is designed with a 300bars working pressure. When it is used with pressures over 200 bars it is advisable to use the optional threaded DIN connection to the tank valve instead of the standard INT. yokeconnection.SORIUSand SORIUS 1000REGULATORS - 2nd STAGEThe main body is made from synthetic resinwhich is highly resistant to impacts, abrasions, ultraviolet rays and chemical agents. Incorporating silicone membranes and valve seat with internal component parts in chrome plated brass and stainless steel. The mouth- piece is manufactured from medical grade sili- cone rubber. The second stage is a "downstream" type valve with an air flow channel exploiting a "Venturi effect". The result is an air flow delivery which is perfectly controlled by the diver's breathing action. Note: a normal breathing action produ- ces a light air flow while a higher breathing action, (due to heavy work or deep diving), produces a high air flow which is supported by the Venturi effect. This system allows for low consumption of air by reducing air waste as it is designed to per- fectly fit the divers air demand. The "downstream" valve also provides maxi- mum safety as it is also able to work in case of 1st stage overpressure, by releasing the exces- sive pressure, and allowing the diver to breathe. The low pressure hose is of the standard type (length mm 760 - thread 3/8”).OCTOPUS SORIUS The SORIUS 1000 regulator is designed with a 300 bars working pressure. When it is used with pressures over 200 bars it is advisable to use the optional threaded DIN connection to the tank valve instead of the standard INT. yoke connection.SORIUS AND SORIUS ADJ REGULATORSFIRST STAGEThis first stage combines very high performan-ce with an extremely compact and functional shape. The SORIUS is a balanced diaphragm regula- tor which gives you an intermediate pressure which is always constant regardless of tank pressure or depth. The diaphragm completely separates the "heart" of the regulator from the external envi- ronment and provides high reliability over a large number of dives. It is manufactured from a single block brass body which is copper, nickel and chrome coa- ted. The internal component parts are in chro- me/nickel coated brass, the springs in stainless steel and the seals are made in nitril rubbers. Four low pressure ports, with 3/8” thread, sup- ply a constant intermediate pressure of 9.8 bars; the high pressure port has a 7/16” thread and a flow reduction hole of 0.20 mm diam. These high pressure ports are used to connect a diving pressure gauge by means of a hose pro- vided with a 7/16” male connection. WARNINGUse only standardised thread pressure gauge. Do not use any type of adapter between the 1st stage and the high pressure hose connection.
