4. Setup Guide
- Positioning the Air Pump: Place the air pump on a flat, dry surface above the water level of your aquarium. If placing it below the water level, a check valve is mandatory to prevent water backflow.
- Connecting Air Tubing: Connect one end of the air tubing (not included) to the air outlet nozzle on the pump.
- Installing Check Valve (if necessary): If the pump is below water level, cut the air tubing and insert a check valve (not included) in the line, ensuring the arrow on the valve points towards the air stone.
- Attaching Air Stone: Connect the other end of the air tubing (or the check valve output) to an air stone (not included).
- Placing Air Stone: Submerge the air stone in your aquarium to the desired depth.
- Power Connection: Plug the air pump into a suitable power outlet.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your air pump.
- Clean Air Intake Filter: Periodically check and clean the air intake filter located at the bottom of the pump. Dust and debris can accumulate, reducing airflow. Gently wipe or brush away any buildup.
- Inspect Air Tubing and Air Stone: Regularly inspect the air tubing for kinks or blockages and the air stone for clogging. Clean or replace these components as needed to maintain consistent air output.
- Check Valve Inspection: If a check valve is used, ensure it is functioning correctly and not obstructed.

7. Troubleshooting
- No Air Output:
- Ensure the power cord is securely plugged into a working outlet.
- Check for kinks or blockages in the air tubing or air stone.
- Verify the air intake filter is not completely clogged.
- Weak Air Output:
- Clean the air intake filter.
- Inspect air tubing and air stone for partial blockages or wear.
- Ensure the air stone is not too deep for the pump's capacity.
- Excessive Noise:
- Ensure the pump is placed on a flat, stable surface.
- Check that the rubber feet are intact and providing proper vibration dampening.
- Verify that the air tubing or other components are not vibrating against the aquarium or other surfaces.
