Setup Instructions
Follow these steps to properly set up your Oxygen Regulator with an oxygen tank and accessories.
- Inspect Components: Before installation, ensure all components are present and free from damage. Verify the regulator, wrench, brass yoke washer seals, and oxygen tubing swivel nipple are in good condition.
- Prepare Oxygen Tank: Ensure the oxygen tank valve is clean and free of debris. Use the provided cylinder valve wrench to slightly open and then close the tank valve to clear any dust or particles.
- Install Yoke Washer Seal: Place one of the brass yoke washer seals into the inlet connection of the regulator. This seal is crucial for preventing leaks.
- Attach Regulator to Tank: Align the regulator's CGA 870 inlet connection with the oxygen tank's valve. Hand-tighten the yoke screw securely. Then, use the provided cylinder valve wrench to tighten the yoke screw further until the regulator is firmly attached and no gas leaks are detected.
- Connect Accessories (Optional):
- Humidifier Bottle: If using a humidifier bottle, connect it to the DISS outlet on the regulator. Ensure it is securely threaded and upright.
- Oxygen Tubing Swivel Nipple: To convert the DISS outlet to a barb outlet for direct tubing connection, thread the oxygen tubing swivel nipple onto the DISS outlet. Ensure it is tightly secured.

Operating Instructions
Once the regulator is securely attached to the oxygen tank, you can begin operation.
- Open Tank Valve: Slowly turn the oxygen tank valve counter-clockwise to open it. The pressure gauge on the regulator will indicate the tank's internal pressure (operating inlet pressure 300 to 3000 PSI).
- Set Flow Rate: Locate the flow selector knob on the regulator. Rotate the knob to select the desired oxygen flow rate. The available flow settings for the 0-15 LPM model are: 0, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 15 LPM. Ensure the selector clicks into place at the chosen setting.
- Monitor Flow: The clear flow rate window will instantly display your selected LPM. The pressure gauge continuously shows the tank pressure.
- Close Tank Valve: When oxygen therapy is complete, turn the oxygen tank valve clockwise to close it completely.
- Bleed Regulator: After closing the tank valve, allow the remaining oxygen in the regulator to bleed out by leaving the flow selector open until the pressure gauge reads zero. Then, turn the flow selector to '0' or off.

Maintenance
Regular maintenance ensures the longevity and safe operation of your oxygen regulator.
- Yoke Washer Seals: The brass yoke washer seals are consumable items and should be inspected regularly for wear or damage. Replace them as needed to ensure a leak-free connection. The product includes 5 replaceable brass yoke washer seals.
- Cleaning: Wipe the exterior of the regulator with a clean, damp cloth. Do not use oil, grease, or any petroleum-based products on or near the regulator, as these can react violently with oxygen.
- Storage: Store the regulator in a clean, dry place away from direct sunlight and extreme temperatures when not in use.
