| USING ENRICHED AIR NITROX (EAN) AWARNING: This section of your owner's manual contains Important information regarding the use of your equipment with enriched air (EAN / Nitrox). Do not attempt to use this product with enriched air until you have read and understand this section of the manual. To do otherwise increases your risk of injury or death. AWARNING: Obtain an EAN (Nitrox) Certification. In order to enjoy the special benefits that EAN/nitrox can provide, it is extremely important to obtain special training from a nationally recognised training agency in addition to that which is provided for openwater SCUBA. AWARNING: The maximum operating depth of your regulator and exposure times are dependent on the oxygen content of the gas you are using. Your Apeks regulator has been prepared for use with Enriched Air Nitrox (EAN) where the percentage of oxygen in the EAN does not exceed 40%. This is possible because each regulator is built to a high standard of cleanliness using EAN compatible components and lubricants. In addition, each regulator design has passed stringent adiabatic compression testing to ensure its safety and compatibility with increased percentages of oxygen. If it is your intention to use your new Apeks regulator with EAN (O2 not to exceed 40%), it is imperative that you maintain the internal cleanliness of the regulator (see section on Care and Maintenance, page 25). If it is your intent to use the regulator interchangeably with breathing air, the breathing air should be oxygen-compatible or "hyperfiltered" whereas the condensed hydrocarbons do not exceed 0.1 mg/m3. Your local authorised Apeks dealer ran help you determine whether the breathing air that they provide meets this criterion. Standard compressed breathing air, often referred to as Grade E, or 6 |
