Setup
1. Assembly
- Attach the first stage regulator to the 1.9L DOT cylinder, ensuring a secure and airtight connection.
- Connect the second stage breathing valve to the first stage regulator.
- Secure the assembled scuba tank to the diving vest, ensuring it is firmly positioned on the back.
2. Inflation
The SMACO Mini Scuba Tank can be inflated using two primary methods:
- Using a Scuba Adapter: Connect the 8mm inflation interface of the mini tank to a full-sized scuba cylinder via a scuba adapter. Air can typically be transferred in approximately 10 seconds.
- Using an Air Compressor: Connect the 8mm inflation interface to a compatible air compressor. Inflation typically takes about 45 minutes.

Operating Instructions
1. Pre-Dive Checks
- Verify that all connections are secure and free from leaks.
- Check the pressure gauge on the first stage regulator to ensure adequate air supply.
- Confirm the second stage breathing valve is functioning correctly.
2. Diving
The 1.9L scuba tank provides approximately 115 breaths at 200 bar (tested at 33 ft depth). Actual diving time may vary based on depth and environmental conditions.
- Shallow Water Diving: For activities such as diving practice, underwater fishing, pool salvage, boat bottom cleaning, and water rescue, the maximum recommended depth is 10 meters (33 feet).
- Backup Air Source: When used as a backup air source, the maximum diving depth can extend to 30 meters (100 feet).
- Breathing: Breathe normally through the silicone mouthpiece. The second stage valve allows for adjustment of air flow.
- Continuous Monitoring: Always monitor the pressure gauge to track remaining air supply and plan your ascent safely.
