3. Package Contents
Please verify that all items are present in the package:
- 1 x AQQA Air Pump
- 1 x Check Valve
- 1 x Air Stone
- 1 x Air Line (Hose)
- 1 x USB Cable
4. Setup Instructions
- Connect Air Line: Attach one end of the air line (hose) to an air outlet on the pump.
- Attach Air Stone: Connect the air stone to the other end of the air line.
- Placement: Position the air pump above the water surface of your aquarium. This prevents water from siphoning back into the pump in case of power loss.
- Install Check Valve (Crucial for Safety): If the air pump must be placed below the water surface, a check valve is essential. Cut the air line and insert the check valve in the middle, ensuring the airflow direction is correct (towards the air stone). This prevents water backflow into the pump, which can cause damage or electrical hazards.
- Submerge Air Stone: Place the air stone into the aquarium water.
