5. Setup
- Connect Tubing: Attach one end of each airline tubing to the air pump's outlet ports.
- Attach Air Stones: Connect an air stone to the other end of each airline tubing.
- Install Check Valve: For optimal performance and to prevent water backflow into the pump, install the check valve in one of the airline tubings between the pump and the air stone. Ensure the check valve is oriented correctly, following the airflow direction indicated on the valve.
- Position Air Stones: Place the air stones into the water (aquarium or bait bucket).
- Initial Charge: Ensure the pump is fully charged before its first use. Connect the Type-C charging cable to the pump and a suitable USB power source.
6. Operating Instructions
- Power On/Off: Press the power button (labeled with a circle and vertical line) to turn the pump on or off.
- Select Mode: Press the 'INT' button to switch between Normal (continuous airflow) and Intermittent modes. The mode indicator light will show the current mode (steady for normal, flashing for intermittent).
- Adjust Airflow: Use the '+/-' buttons to select one of the four available airflow levels.
- Battery Indicator: Monitor the battery level using the indicator lights on the display to know when recharging is needed.
7. Maintenance
- Cleaning Air Stones: Periodically clean air stones to prevent clogging and maintain efficient airflow. Soaking them in a mild vinegar solution can help remove mineral buildup. Replace air stones if they become heavily clogged or damaged.
- Tubing Inspection: Regularly check airline tubing for kinks, cracks, or blockages that could impede airflow. Replace damaged tubing as necessary.
- Charging: Recharge the battery when the indicator shows low power to ensure the pump is always ready for use.
- Storage: When not in use, store the pump in a dry, cool place. Ensure it is clean and fully charged before storing for extended periods to preserve battery life.
8. Troubleshooting
- No Airflow:
- Check if the pump is powered on and adequately charged.
- Inspect airline tubing for kinks or blockages.
- Clean or replace air stones if they appear clogged.
- Weak Airflow:
- Ensure the battery is sufficiently charged.
- Adjust the airflow level using the '+/-' buttons to a higher setting.
- Check for partial blockages in the tubing or air stones.
- Pump Not Charging:
- Verify the Type-C cable is securely connected to both the pump and the power source.
- Try a different USB power adapter or a different USB port.
- Ensure the charging port on the pump is dry and free of any debris.
- Unusual Noise:
- Ensure the pump is placed on a stable, flat surface.
- Check for any foreign objects obstructing the air intake or outlet.
