2 - NITROX USE • The use of NITROX regulator requests a specific “NITROX Diver” training. • NITROX regulator must be fitted on NITROX tank with M26x2 connexion (EN144-3 Standard). • Check the pourcentage value of your NITROX mix and conduct your dive with its max depth restriction. • The BEUCHAT NITROX regulators are compatible with 100% (i.e. for 3m and 6m deco stops use). • NITROX markings and colors (Yellow and Green) are specific identifying elements of a NITROX regulator. • Have an annual maintenance session for your NITROX regulator by a NITROX certified BEUCHAT dealer. • Only use BEUCHAT NITROX spare parts for the mainte- nance of NITROX regulator. • Always protect your NITROX regulator first stage with the attached special plug to prevent any contamination (grease, particules, dust, ...).
