The diver gets an active breathing resistance warning when approximately 20 % of the SCUBA cylinder air supply remains 60-70 bar (870-1015 psi). The warning occurs on the high end of this pressure range when the air consumption rate is high.

For additional information see DIVATOR HATCH User Manual.
  • Page 20 3.7.1 Visor • The visor is designed to minimize the volume of air inside the face mask to reduce the positive buoyancy. If it is necessary to adjust the mask to a neutral buoyancy, weights are available which can be attached to each side of the visor.

  • Page 21: Full Face Mask And Breathing Valve

    Regulations state that breathing valves and face masks must be regularly cleaned and disinfected. Furthermore, breathing valves and face masks that are used by more than one person must be cleaned and disinfected after each use. Interspiro recommends personal breathing valves and personal face masks as the most hygienic solution.

    3.10 dIVAtoR bUoYAnCY CoMPensAtInG jACKet (bCj) The Interspiro BCJ stabilizing jacket design features flexible buoyancy control. The stabilizing jacket uses unrestricted internal channels that allow air to constantly flow throughout the jacket, accumulating at the highest point. The diver is surrounded by the bubble of air flow and can move easily and precisely. At the surface, the stabilizing jacket provides the diver with a comfortable fit, floating ease, and the ability to be in the 'face up' position.

    3.12 WeIGHts • The DIVATOR Lite Cylinder pack must be compensated with weights in order to be neutral or negative in water. The advantage of this system is that the total weight of the DIVATOR Lite Cylinder Pack is divided into two parts, where the heaviest part (brass cylinder weight) can stay at the dive site or boat while the DIVATOR Lite Cylinder Pack is easily transported to be recharged.

  • Page 46 1996. 6.2.2 breathing Valve All Interspiro breathing valves supply air during inhalation. When the diver inhales, air flows from the breathing hose through the breathing valve and into the diver's lungs. The expansion of the supplied air results in the air near the inlet valve being cooled to around -10°C (14°F) at a water temperature of 0°C (32°F).
  • Page 47 6.2.5 Procedures for Repeated dives in Cold Water and/or Low Air temperature 1. Prepare for the next dive by shaking water out of the full face mask and the breathing valves.

  • Page 69: Transport And Storage

    Before the air cylinders are transported, the applicable rules for transport must be complied with. For certain types of transport, the air cylinders must be depressurized. Use Interspiro 331 190 800 discharge plug, which leaves a residual of about 2 bar (30 psi) in the cylinders. For a long period of storage, the storage environment should be dark, dry, and cool, with minimal temperature changes.
