WARNING The regulator is not intended to be used by untrained persons who may not know the inherent risks and hazards of SCUBA diving. Prior to use of the regulator equipment with nitrogen-oxygen (Nitrox) breathing gas mixtures that contain a higher fraction of oxygen than 22%, the user must have received, or must first obtain, certification in diving with Nitrox from a recognized training agency When the breathing mixture contains oxygen content greater than 22 %, you must use a...

If not specified otherwise the contaminants shall be kept to a minimum, but in any event shall not exceed the permissible exposure level. The mineral oil content shall be such that the air is without odor of oil. NOTE: The odor threshold is in the region of 0.3mg/m³.

Your new regulator has been designed and manufactured with pride, per the most exacting standards for quality and performance.
  • Page 7 WARNING DO NOT ATTACH A LOW-PRESSURE HOSE TO A HIGH-PRESSURE PORT (MARKED HP) OR A HIGH-PRESSURE HOSE TO A LOW-PRESSURE PORT Balanced Second Stages DESIGNED TO OPERATE AT 135~145 psi. Low-pressureand high-pressure port thread sizes are different. Please use the HP HOSE to connect with the high-pressure ports.(Be sure that you only place a high-pressure accessory or hoses in ports specifically marked with the letters “HP”, or ”4500 psi / 300bar.), and use the low-pressure hose to connect with the low-pressure port.

  • Page 9 Examine the threads in the valve to ensure they are clean and free of burrs or defects that could damage the threads of your regulator DIN fitting. Examine the sealing O-Ring (As568- 111, N90) located on the DIN first stage to ensure that it is not cut, scrubbed, or deteriorated.
  • Page 10 Replace the O-Ring if it is damaged. Use care not to cross the threads. Thread the DIN connector wheel clockwise into the cavity of the tank valve until it is secure. (FOR DIN STYLE) Slowly open the tank valve (with the pressure gauge facingaway from you). Momentarily purge the second stage and then listen to ensure that no breathing gas is leaking from the regulator or valve connection.
  • Page 11 DO NOT blow breathing air near a first stage that does not have the dust protector in place. Dry the dust protector, position it within the yoke, and secure it by tightening the yoke knob. (FOR YOKE STYLE) Place the protector cap on the threads of the regulator DIN connector wheel. (FOR DIN STYLE) REMOVAL OF HOSES FROM FIRST STAGE WARNING: Purge all pressure from the first stage before attempting hose removal and...
  • Page 12 This condition, referred to as free-flow, can usually be stopped by turning the second stage so the mouthpiece is pointing down and the purge button is pointing up. It is recommended to carry an Octopus (alternate air source) with the mouthpiece facing down when not in use, turn the Venturi pad lever to the minimum setting or use a mouthpiece plug or cover to prevent free-flow in case it is bumped.
  • Page 13 VENTURI PAD LEVER The second stages fitted with a deflator-effect adjusting lever. This lever modifies the inhaled air flow by means of an internal vane. This allows the breathing performance of your regulator to be adjusted to match your needs. When the Venturi pad lever is set on “max”...
  • Page 14 SENSITIVITY ADJUSTING KNOB This inhalation adjusting knob allows you to adjust the sensitivity of the regulator. This is done to prevent undesirable loss of breathing gas (free flowing) that often occurs when a high-performance regulator second stage is connected as an octopus second stage, or when the primary second stage is not in the diver’s mouth, such as when surface swimming.
  • Page 15 CLEAN OR CHANGE THE COVER RING OR THE PURGE COVER If you want to clean or change the different color (or style) of the ring or purge cover, please use the following process. The regulator should NOT be connected to the SCUBA Cylinder. 1.

  • Page 20 Your regulator’s performance relies greatly on the care and maintenance it will receive, in addition to regularly scheduled services. Before you dive with your new OMS regulator, it is important to read this manual in its entirety to become familiar with the regulator’s features.
  • Page 21 30 meters, (98ft) and 10°C (50°F),OMS recognizes that emergencies can happen beyond these limits. To ensure OMS products perform well in all conditions in this type of situation, OMS has designed those products to far exceed the minimum requirements. This means they match with the performance of the primary demand regulators they are intended to work with, in water temperatures in 4°C (39.2°F) where stated, and to depths of 50 meters.

  • Page 22: Pre-Dive Checkout

    Pre-Dive Checkout Before each use, the OMS regulator must be given a through visual inspection and functional test. NEVER dive with a regulator that shows signs of damage, or provides substandard performance. Please send the until in for service to OMS or an OMS authorized dealer.
  • Page 23 the hoses are not blistered, cut, or otherwise damaged. If hose protectors are present, slide the protectors back to expose the hose fittings, and inspect the hoses as described above. 2. Visually inspect both the first and second stage regulators for any signs of external damage.

  • Page 24: During The Dive

    During the Dive When you are ready to submerge, place the second stage in your mouth and set the Venturi pad lever to your desired position. Turn the inhalation control knob out (counterclockwise) until the regulator breathes comfortably without leaking or being undesirably sensitive.

  • Page 25: Repairs And Service

    All service must be performed by an authorized OMS supplier or dealer. If verdigris or contaminant residue is found on the surface of the filter, it is strongly recommended NOT to dive with the regulator until it has received factory-prescribed service from an authorized supplier or dealer.
  • Page 26 Equipment should be inspected prior to every use. Equipment should be serviced at least once every six months regardless of use. Equipment should be serviced after 100 dives prior to further use. Equipment stored for more than three months should be inspected and serviced as required prior to use.
