2-Pack Silicone Mouthpiece Replacement for Regulator
- Made from soft, food-grade silicone for comfort and durability.
- Reduces jaw fatigue, perfect for extended underwater use.
- Includes 2 mouthpieces.
Battery Maintenance
- If the machine will not be used for an extended period, keep the battery charged between 70%-80% to prolong its lifespan.
- Perform a charge and discharge cycle every six months, charging for about 30 minutes each time.
- Avoid storing the device in extreme temperatures, as high or low temperatures may damage the battery.
- Prevent deep discharge; prolonged low battery levels can lead to battery degradation or failure.
Cleaning and Storage
- Clean the surface of the machine and the breathing tube accessories with fresh water after each use. Ensure all parts are thoroughly dried before storage to prevent damage from moisture.
- During cleaning, make sure no water or debris enters the air inlet, as this could damage the internal components. Use protective covers or waterproof materials to safeguard the air inlet while cleaning.
- When storing the device for a long time, cover it with a dustproof cover to protect it from dust and dirt.
- Avoid bending the breathing tube excessively during storage to prevent material fatigue or damage.
Environmental Requirements
- Store the device in a dry, well-ventilated area, away from direct sunlight, high temperatures, or high humidity.
- Keep the device away from chemicals or corrosive substances to prevent damage to its surface materials.
Regular Inspections
- Periodically check the breathing tube and device connectors for wear, aging, or loosening. Replace or repair parts as necessary.
- If the device shows any irregularities, such as increased noise or difficulty inhaling, stop using it immediately and contact a professional for inspection and repairs.
Transportation Precautions
- When transporting or carrying the device, ensure it is powered off and stored in a dedicated protective case or bag to prevent damage from impacts or pressure.
- For long-distance transportation, adjust the battery charge to 70%-80% beforehand to avoid over-discharging during the journey.
Following these maintenance tips will help extend the lifespan of your ventilator and ensure it performs at its best.
