Nitrox-Ready Valve

• This valve is to be operated, maintained, and installed only by individuals who have been trained by a recognized agency on SCUBA diving.

• This valve is designed for SCUBA diving and should not be used for any other purpose. If this valve has the letter "E" after the manufacturing month and year on the valve body, the valve as manufactured (new) may be used for either oxygen-enriched breathing air with a maximum oxygen content of 40% OR Grade E breathing air (21% oxygen and 79% nitrogen by volume). Once the valve is used for Grade E breathing air, it must be dedicated to breathing air service and MAY NOT be used for oxygen-enriched breathing air.

• If this valve is used for oxygen-enriched air, this valve is to be operated, maintained, and installed only be individuals who have been trained by a recognized agency in the use of oxygen-enriched breathing air.

• IF AT ANY TIME THIS VALVE IS USED WITH GRADE E BREATHING AIR OR ANY GAS OTHER THAN OXYGEN-ENRICHED BREATHING AIR, DO NOT USE THE VALVE FOR OXYGEN-ENRICHED BREATHING AIR THEREAFTER!

• If this valve is to be used with oxygen-enriched breathing air, this valve must be installed in a cylinder which has been cleaned and tested for oxygen-enriched breathing air use. All other equipment attached to the valve which comes in contact with the oxygen-enriched breathing air (regulator, BC, gauge panel, etc.) must also be approved by the manufacturer of the attachment for use with oxygen-enriched breathing air.

• If used with oxygen-enriched breathing air, valve, cylinder, and all attachments which come in contact with the oxygen-enriched breathing air must be maintained in an oxygen-clean condition. Any contamination by oil, grease, dust, or any contamination will cause a hazardous condition which could result in an explosion of the valve, cylinder, regulator, or other equipment. If the valve and cylinder is contaminated by oil, grease, etc., the valve and cylinder must be re-cleaned and tested for oxygen use by a competent facility and in accordance with Compressed Gas Association Pamphlet G-4.1 "Cleaning Equipment for Oxygen Service."

• If a lubricant is used on the O-rings or upon insertion of the valve into a cylinder, only use lubricants approved for oxygen use.

• Before attaching the regulator to the valve, open the valve slightly for an instant in order to clear the opening of particles of dust, dirt, and to remove any moisture.

• ALWAYS OPEN VALVE SLOWLY UNTIL PRESSURE BUILDS UP THROUGHOUT THE REGULATOR!

• As per the recommendations of the O-ring manufacturer, this valve may only be used in a temperature range above -13°F (-25°C).

• Valve is to be used and maintained according to Compressed Gas Association Pamphlet V-9 "Standard for Compressed Gas Cylinder Valves."

• The valve must be inspected/serviced every year by a competent facility. If there are signs of any corrosion or roughness in operating the valve, immediately return the valve to the store where you purchased it for inspection and/or repair.
