4. Intended use
Demand regulators presented in this manual are diving air regulators used for
recreational and professional diving. Demand regulators are used with a single diving
cylinder or any air twinset of operating pressure up to 30 MPa (300 atm).
CAUTION
SCUBATECH shall not assume responsibility for malfunctioning of demand
regulators if they have been used contrary to their purpose, if unoriginal spare
parts have been used or if they have been serviced by an authorized person.
5. Using with nitrox
IMPORTANT
Important information regarding the use of demand regulators with nitrox
mixtures is described below.
CAUTION
Diving with the use of nitrox mixtures requires completion of a specialist
training carried out by a qualified instructor.
CAUTION
The maximum operating depth and the time of exposure to nitrox mixtures
depend on oxygen concentration in the used mixture. High oxygen
concentration reduces the use of mixtures with standard diving equipment and
it requires application of materials and procedures that differ from those
required by a user of standard compressed air.
Using demand regulators with nitrox mixtures outside the EU (European
Union).
Standard Scubatech demand regulators sold to non-member EU countries are
produced with the application of materials, assembly procedures and greases that
ensure compatibility with nitrox mixtures of the maximum oxygen content of 40 %.
CAUTION
If before using with nitrox mixtures a demand regulator was used with standard
compressed air, it is recommended to carry out a proper maintenance
procedure. An authorized Scubatech serviceman should provide all required
information.
