Maintenance
- Rinsing: After each use, thoroughly rinse the tank and all components with fresh water to remove salt, sand, or other debris.
- Drying: Allow all parts to air dry completely before storage. Avoid direct sunlight.
- Storage: Store the tank in a cool, dry place, away from direct sunlight and extreme temperatures. Keep the tank partially pressurized (e.g., 200-300 PSI) to prevent moisture ingress.
- Mouthpiece and Hose: Periodically clean the silicone mouthpiece and low-pressure hose. If an industrial smell or oily residue is detected, clean thoroughly or consider replacing the hose.
- Valve Cap: Ensure the cap covering the fill nipple is tight to prevent water from entering during use or storage.
- Professional Servicing: It is recommended to have the tank and regulator serviced by a qualified technician annually or as recommended by diving standards.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Air leakage from tank valve or connections. | Loose connection, damaged O-ring, or faulty valve. | Tighten connections. Inspect and replace O-rings if damaged. If problem persists, seek professional service. |
| Difficulty reading pressure gauge. | Numbers are small or condensation inside. | Familiarize yourself with the gauge's color codes. If condensation is an issue, ensure proper drying and storage. |
| Mouthpiece valve feels "sticky" or hard to breathe from. | Accumulation of salt/debris, or internal adjustment needed. | Rinse thoroughly with fresh water. If problem persists, professional adjustment may be required. |
| Unpleasant smell or taste from air. | Contaminated air source, or residue in hose/tank. | Ensure tank is filled with breathing-grade air. Clean hose and tank interior thoroughly. If problem persists, do not use and seek professional advice. |
| Water entering fill nipple. | Loose or missing protective cap. | Always ensure the fill nipple cap is securely in place when not filling. |
