TERMINOLOGY / APPLICATIONS SCUBAPRO® recreational diving equipment includes: self-contained, open circuit compressed air underwater breathing apparatus (i.e. SCUBA). SCUBA equipment allows a diver to breathe underwater by carrying a portable supply of regulated compressed air with him underwater. The purpose of a breathing regulator system is to reduce the pressure of the compressed air in the cylinder and supply breathable air to the diver upon demand. The system also provides outlets for underwater pressure gauges and intermediate pressure hoses for inflation of buoyancy control devices, dive suits, etc... NOTE: FOR SIMPLICITY, PRESSURE REGULATORS AND DEMAND VALVES ARE REFERRED TO AS "1st STAGE" AND "2nd STAGE" REGULATORS, RESPECTIVELY, THROUGHOUT THE REST OF THIS DOCUMENT. A breathing regulator system consists of: a first stage regulator coupled with one or more second stage regulators which have depth limitations. Any individual diving activitiy is limited by the experience and condition of the individual diver. SCUBA should not be used deeper than 50 meters (130 ft). EN250:2000 regulates the minimum requirements for recreational SCUBA equipment in Europe. SCUBAPRO® equipment conforms to EN250:2000. I-2 ENGLISH User Instructions for Breathing Regulators EN250:2000 requires that the minimum SCUBA unit consist of the following elements: · Compressed air cylinder(s) conforming to national regulations of the corresponding European Standard. · Breathing regulator: consisting of a first and second stage regulator set. · Face mask and mouthpiece, full face mask, or diving helmet. · Frame or holding device for air cylinder(s) with the possibility to mount the harness. · Carrying system. · Safety system, including at least one of the following: a. submersible pressure gauge, b. reserve valve, c. active low pressure warning device. · Instructions for use must be included. 3. TECHNICAL SAFETY REGULATIONS The recommendations and advice of a recognized recreational diving instructional agency should be followed on every dive. Before participating in any diving activity, a thorough course of instruction in the theory and practices involved in diving should be successfully completed. This user instruction guide does not replace a complete course of diving instruction! Prospective diving students should undergo and pass a diving medical examination prior to commencing instruction. Active divers should be re-examined as required by their physician. Air cylinders should by filled with quality compressed air only (in accordance with EN 12021). Poor quality air can cause corrosion to form in the cylinder as well as lead to regulator system icing and malfunction in low temperature environments. When transporting high pressure cylinder(s), national and local regulations for the transportation of dangerous goods (GGVS) should be observed. Regulations for using air cylinders is covered in the "use and handling of gasses" (TRG 402, para 4 and 5) and is described in other governmental regulations. Cold water diving regulator: SCUBA systems intended for use in temperatures below 10°C (50° F) must employ regulator sets proven for cold water diving. Required safety devices: In addition to those requirements detailed in "2 Terminology / Applications" SCUBA sets intended for use in certain exceptional operations conditions must meet additional criteria. · Whenever the amount of air remaining must be known (e.g. cave, cavern, wreck, current, or ice diving) a submersible pressure gauge (spg) is required. · Whenever the use of a spg is difficult or impossible (e.g. Iow visibility) a reserve valve or active warning device is required.

I-4 ENGLISH User Instructions for Breathing Regulators 5. TECHNICAL DESCRIPTIONS High quality material and engineering used in the manufacture of SCUBAPRO® regulators insure maximum reliability and safety. SCUBAPRO® has been building high quality diving equipment for over 35 years. All SCUBAPRO® regulator systems consist of two stages. The 2nd stage is a negative pressure activated, breathing controlled demand regulator. The 1st stage, connected to the cylinder valve, is intended to reduce the high pressure air supply (200-300 bar) down to an intermediate pressure of 9.5 bar (135 psi) over ambient pressure. The regulated pressure air is supplied to the 2nd stage via a low pressure hose. 5.1 A.F. and T.I.S. (ANTIFREEZE MK25's and THERMO INSULATING SYSTEM) (EU/USA patents) The above two systems for first stages regulator have to be installed by a qualified SCUBAPRO® service technician. They have been designed to provide resistance to freezing in accordance with European Norms (EN250:2000) for cold water performance at < 10°C (50°F) (ref. section 5.11.3). 5.2 Thread or Yoke Connections SCUBAPRO® first stage regulators are currently available with either of two different cylinder valve connections : · Threaded : this connector uses a knurled and threaded retaining wheel and complies with ISO 12209-2 (200 or 300 bar). · Yoke : this international connector consists of a yoke and knob type fixing screw for use in systems up to 230 bar and complies with ISO 12209-1. Cylinder connections can be exchanged by an authorized SCUBAPRO® repair technician. 5.3 Conical sintered filter The conical sintered filter has a 300% larger surface area than disc shaped filters. The filter traps rust and other large particles before their entering into the 1st stage regulator. 5.4 H.P. cave cone seat Designed and patented by SCUBAPRO®, the cave cone seat in the balanced piston first stages eliminates the annoying "whistling" common with other piston type 1st stages. (EU patent Nr 0.310.738). 5.5 Down-stream system "Down-stream" describes a valve that opens with air flow. With a down-stream system, the delivery valve in the 2nd stage opens automatically (like a safety valve) if the intermediate pressure supplied by the 1st stage increases above expected I-5 User Instructions for Breathing Regulators pressures. This approach insures that air is supplied to the diver should the 1st stage malfunctions and offers considerably lower inhalation resistance compared to an "up-stream" configuration. 5.6 Intermediate pressure hose In 1983 SCUBAPRO® developed an intermediate pressure "SuperFlow" hose that has a 33% higher air flow capacity for the same external diameter. The SuperFlow hose fits all SCUBAPRO® regulators, including those manufactured before 1983. 5.7 Mouthpiece The orthodontic mouthpiece is designed to fit perfectly in the mouth and adapt to teeth and gums achieving maximum comfort whilst securing the second stage firmly in place. 5.8 Full face mask Any SCUBAPRO® 2nd stage regulator, minus the mouthpiece, can be fitted to the SCUBAPRO® full face mask (p/n 24.150.000) by an authorized SCUBAPRO® repair technician. 5.9 Registration All SCUBAPRO® regulators are marked with a serial number (s/n). On the metal 2nd stages, the s/n can be found on the rear surface above the bubble deflector. On most plastic 2nd stage regulators, the s/n may be found on the rear face of the bubble deflector or on the mouthpiece surface. The D400 has the s/n on the side of the body. All 1st stage regulators display the s/n on the main body. 5.10 Silicone The diaphragm and air exhaust valve are manufactured from fine, highly sensitive silicone material. This extremely flexible material reduces the effort required for breathing during both inhalation and exhalation. 5.11 Compatibility Reverse compatibility; a company philosophy. New components are designed to be compatible with older versions of similar models. Even an old MK5 1st stage can be brought up to date with the latest components. 5.12 Worldwide Lifetime Guarantee SCUBAPRO® offers the original owner of all new breathing regulators a lifetime guarantee covering material and manufacturing defects for all components except mouthpieces and intermediate pressure hoses. Documented annual service and inspection by an authorized SCUBAPRO® repair technician is mandatory to maintain this Guarantee. 5.13 EN250:2000 Approval All SCUBAPRO® regulators exceed the strict requirements required by the European Standard EN250:2000. When fitted with a T.I.S./A.F. (antifreeze) kit, all SCUBAPRO® 1st stage regulators conform to the requirements for cold water conditions. I-6 ENGLISH User Instructions for Breathing Regulators 5.14 V.l.V.A. (Venturi lnitiated Vacuum Assist) Many SCUBAPRO® regulators are equipped with a diver-controlled V.I.V.A. Others have an internal V.I.V.A. or one that can be adjusted by an authorized SCUBAPRO® technician. V.l.V.A. (US Patent 4,796,618) allows the diver to finely control the inhaled air stream. This is possible by situating a flow vane in the mouth piece orifice. The an ...
