35IntroductionCongratulations! Continual research and evolution carried out atour technical centres, together with Cressi-sub’ s usual reliability,have led to the product you just purchased, which will allow youto dive comfortably and safely for a long time.All Cressi-sub regulators are certified to be used up to 50 m/164ft. depth and in cold water at temperature inferior than 10° C/50°F: they have in fact passed the strict working test at 4° C (+0 -2), as prescribed by UNI EN 250:2000 standard, in compliancewith 89/686/EEC directive, which provides the conditions atwhich Individual Safety Devices can be put on the market, as wellas their essential safety requisites.NOTE: This handbook does not replace a diving training course!All Cressi-sub devices must be used by divers who haveattended regular courses held by certified trainers.Using underwater devices without a licence or the necessarytechnical training may be dangerous for the diver’ s safety andlife itself.Besides, in order to guarantee the maximum safety, the devicesmust be serviced only by the producer or an authorizedcentre. WARNING: CRESSI-SUB DECLINE ANY RESPON-SIBILITY FOR ANY SERVICING CARRIED OUT BYUNAUTHORIZED PERSONNEL.ENGLISHMain componentsRegulators’ main task is reducing the pressure of the compressedair contained in the tank to the same level as the environment’s, supplying breathable air when required by the diver.They are composed of a “first stage”, working as main pressurereducer and a “second stage” (kept in the diver’ s mouth), whichadjusts the pressure precisely to the same value as the environment’s. The regulator is part – together with tank, valves andsling – of a complete underwater breathing system, known as“SCUBA” (Self Container Underwater Breathing Apparatus).This handbook describes all models of Cressi-sub range, all realizedin high quality materials to guarantee pleasant dives andhigh performance, together with the easiest ways of use andmaintenance.Moreover, all Cressi-sub regulators are designedwith technical peculiarities making several of their componentscompatible one with the others, offering a very comfortablerange of products. WARNING: SCUBA devices complying with EN250:2000 standard must not be used by morethan a diver at the same time. WARNING: in case the components of a SCUBAare set and used by more than a diver at the sametime, their performance in cold water might notsatisfy the requisites prescribed by EN 250:2000standard. WARNING: In order to carry out a totally safedive, Cressi-sub recommend to use a tank suppliedwith a valve featuring two separate outlet ports,with which two complete regulators are to be connected.
