3. Setup and Preparation

This product is the scuba tank only. A compatible regulator and other diving equipment are required for use.

1. 3.1 Initial Inspection

   Upon receiving your SMACO S700 tank, carefully inspect it for any signs of shipping damage. Check the tank body, valve threads (if applicable), and any included accessories. Ensure all markings on the tank are legible.

2. 3.2 Filling the Tank

   • Only have the tank filled by a certified air station or qualified technician.
   • Ensure the air source is clean, dry, and breathable air suitable for diving.
   • Do not exceed the maximum working pressure of 200 bar (20 MPa).
   • The tank should be filled slowly to prevent excessive heat buildup.

3. 3.3 Attaching the Regulator

   Note: A regulator is NOT included with this product.

   • Ensure your regulator is compatible with an M18x1.5 thread and 200 bar working pressure.
   • Inspect the regulator's O-rings for any damage or wear. Replace if necessary.
   • Carefully screw the regulator onto the tank valve, ensuring it is hand-tight. Do not overtighten.
   • Slowly open the tank valve and check for any air leaks. If leaks are detected, close the valve, re-check the O-rings and connections, and re-tighten.

4. Operating Instructions

1. 4.1 Pre-Dive Check

   • Verify the tank pressure using your submersible pressure gauge.
   • Confirm there are no leaks from the tank or regulator connections.
   • Ensure the regulator is functioning correctly and delivering air smoothly.
   • Check all other diving equipment for proper function.

2. 4.2 During the Dive

   • Monitor your air supply regularly.
   • Maintain proper buoyancy control.
   • Ascend slowly and perform safety stops as required by your training.

3. 4.3 Post-Dive Procedures

   • Slowly close the tank valve.
   • Depress the purge button on your regulator to release residual pressure.
   • Carefully unscrew the regulator from the tank valve.
   • Rinse the tank and regulator with fresh water to remove salt and debris.

5. Maintenance and Storage

1. 5.1 Cleaning

   • After each use, rinse the exterior of the tank with fresh water.
   • Dry the tank thoroughly to prevent corrosion.
   • Avoid using harsh chemicals or abrasive materials for cleaning.

2. 5.2 Storage

   • Store the tank in a cool, dry place away from direct sunlight and heat sources.
   • Keep the tank partially pressurized (around 10-20 bar) to prevent moisture from entering.
   • Store the tank securely to prevent it from falling or rolling.
   • Avoid storing the tank with a regulator attached for extended periods.

3. 5.3 Periodic Inspections

   • Visual Inspection: Have the tank visually inspected by a qualified technician annually.
   • Hydrostatic Test: The tank must undergo a hydrostatic test every 5 years (or as required by local regulations) to ensure its structural integrity. The certificate indicates a validity period of up to 10 years for type approval, but individual tank re-testing is typically more frequent.
   • Refer to the tank markings for the last hydrostatic test date and the next due date.

8. User Tips

• Regulator Compatibility: Remember that this product is the tank only. You will need to purchase a compatible regulator separately. Ensure it matches the tank's M18x1.5 thread and 200 bar working pressure.
• Vest/Harness: If you plan to use this tank as a pony bottle or for extended shallow dives, consider a dedicated vest or harness system for comfortable and secure carrying.
• Air Quality: Always insist on clean, dry, and properly filtered breathing air from reputable filling stations. Contaminated air can be dangerous.
