3. Setup Instructions
3.1 Unpacking and Inspection
Carefully unpack all components. Inspect for any visible damage. Ensure all parts listed in the product packaging are present.
3.2 Assembly
- Connect Air Hose: Attach one end of the 45-foot air hose to the designated air outlet on the main diving ventilator unit. Ensure a secure, airtight connection.
- Attach Regulator: Connect the breathing regulator to the other end of the air hose.
- Mouthpiece: Securely attach the mouthpiece to the breathing regulator.
- BCD Integration: If using the BCD, attach the regulator and hose to the BCD as per standard diving equipment practices.

3.3 Charging the Device
Before initial use, fully charge the diving ventilator unit. Locate the charging port, typically protected by a waterproof cover. Use the provided charger to connect the device to a power source. The power display will indicate charging status. A full charge provides approximately 5 hours of operation.
4. Operating Instructions
4.1 Pre-Dive Checks
- Verify the battery level on the power display.
- Confirm all hose connections are secure and free from kinks or damage.
- Test the breathing regulator for proper air flow.
- Ensure the charging cover is tightly sealed.
4.2 Deployment
Place the main diving ventilator unit gently onto the water surface. The unit is designed to float, keeping the air intake above water. Ensure the air intake pipe is clear of obstructions.
4.3 Breathing Underwater
Once in the water, place the mouthpiece in your mouth and begin breathing normally. The regulator will deliver air from the surface unit. Monitor your depth and air supply as needed.


4.4 Post-Dive Procedures
- Remove the device from the water.
- Disconnect the air hose and regulator.
- Rinse all components thoroughly with fresh water, especially after saltwater use.
- Allow all parts to air dry completely before storage.
5. Maintenance and Care
Proper maintenance ensures the longevity and reliable performance of your diving ventilator.
- Cleaning: After each use, particularly in saltwater, rinse the entire system (ventilator unit, hose, regulator, mouthpiece, BCD) with clean fresh water. Do not use harsh chemicals or abrasive materials.
- Drying: Ensure all components are completely dry before storage to prevent mold, mildew, and corrosion.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. Keep it protected from physical damage.
- Battery Care: For optimal battery life, avoid fully discharging the battery frequently. Recharge the battery regularly, even during periods of non-use.
- Cooling Protocol: Adhere to the 5-minute cooling period for every 30 minutes of operation to prevent internal component stress from overheating.
