4. Setup Instructions

Follow these steps to prepare your GOYOJO diving system for use.

4.1 Assembling the Mask and Tank:

1. Ensure both the full-face snorkel mask and the mask-compatible diving tank are clean and free of debris.
2. Align the connector on the mask-compatible diving tank with the port on the full-face snorkel mask.
3. Gently push and twist the tank connector into the mask port until it is securely fastened. Ensure a tight seal to prevent water leakage.

4.2 Inflating the Diving Tanks:

The diving tanks support three inflation methods. Always ensure the tank is securely connected to the inflation device and that the air source is clean and dry.

• Manual High-Pressure Air Pump: Connect the tank to a compatible manual pump. Pump until the pressure gauge indicates the desired pressure, not exceeding 3000 PSI/200 BAR/20 MPa.
• Refill Adapter: Use a refill adapter to transfer air from a larger scuba tank. Ensure both tanks are securely connected and follow the adapter's instructions for safe transfer.
• Electric Inflator: Connect the tank to a compatible electric inflator. Monitor the pressure gauge during inflation to avoid overfilling.

After inflation, disconnect the pump/adapter carefully. Check the pressure gauge to confirm the tank is filled to the appropriate level.

5. Operating Instructions

Understand how to use your GOYOJO diving system for both snorkeling and diving.

5.1 Snorkeling (Surface Use):

When on the surface, the full-face snorkel mask allows you to breathe easily through the dry snorkel, drawing in outside air. The flexible breathing system automatically manages air intake.

• Put on the full-face snorkel mask, ensuring a snug and comfortable fit. Adjust straps as needed.
• Breathe normally through your nose and mouth. The dry snorkel prevents water entry when submerged.
• The one-way exhalation valve will release exhaled CO2, maintaining fresh air inside the mask.

5.2 Scuba Diving (Underwater Use):

When you decide to dive, the GOYOJO scuba tank automatically provides air to the mask, allowing for underwater breathing.

• Before diving, check the pressure gauge on the tank to ensure sufficient air supply.
• Descend slowly and equalize pressure in your ears as needed.
• Breathe calmly and deeply. The mask-compatible tank delivers air directly to the mask.
• Monitor your air supply using the luminous pressure gauge. Plan your dive to ensure you have enough air for a safe ascent.
• For the mouthpiece-equipped tank, insert the mouthpiece into your mouth and bite gently on the tabs. Ensure a good seal with your lips.

6. Maintenance

Proper maintenance extends the life of your GOYOJO diving equipment and ensures safe operation.

• Rinsing: After each use, thoroughly rinse all components (mask, snorkels, tanks) with fresh water to remove salt, sand, and chlorine.
• Drying: Allow all parts to air dry completely in a shaded area, away from direct sunlight, before storage.
• Storage: Store the equipment in a cool, dry place. Avoid extreme temperatures and direct sunlight. Store tanks with a small amount of pressure (e.g., 100-200 PSI) to prevent moisture ingress.
• Inspection: Regularly inspect the mask skirt, straps, O-rings, and tank for any signs of wear, cracks, or damage. Replace worn parts immediately.
• Tank Hydrostatic Testing: Diving tanks require periodic hydrostatic testing as per local regulations. Consult a certified dive shop for this service.
• Cleaning: Clean the mask lens with a non-abrasive cleaner designed for dive masks to maintain anti-fog properties.

7. Troubleshooting

Here are solutions to common issues you might encounter.

• Mask Fogging: Ensure the mask is clean. Apply an anti-fog solution or a small amount of saliva to the inside of the lens, then rinse lightly before use. Ensure a proper seal on your face.
• Water Leaking into Mask: Check for hair caught under the mask skirt. Ensure the mask is properly seated on your face and the straps are adjusted for a snug, but not overly tight, fit. Inspect the mask skirt for damage.
• Difficulty Breathing: Ensure the snorkel is clear of obstructions. If using the tank, check the pressure gauge for sufficient air. Ensure all connections are secure.
• Tank Not Holding Air: Check all O-rings and seals for damage or improper seating. Ensure the tank valve is fully closed when not in use. If the issue persists, seek professional inspection.
• Pressure Gauge Malfunction: If the pressure gauge is not displaying correctly or is stuck, do not use the tank. Have it inspected by a qualified technician.
