1. Product Overview
The Tetra Whisper Air Pump is designed to provide reliable and consistent airflow for aquariums ranging from 20 to 40 gallons. This pump features a patented dome shape, a suspended motor, and sound-dampening chambers to minimize operational noise. Its wide footprint and rubber feet further reduce vibration, ensuring stable and quiet performance. The air pump is essential for oxygenating aquarium water and promoting water movement, which contributes to a healthy environment for aquatic life.

2. Setup Instructions
Follow these steps to properly set up your Tetra Whisper Air Pump:
- Unpack Components: Carefully remove the air pump and all accessories from the packaging. The package includes the air pump, a check valve, and a T-connector.
- Connect Air Tubing: Attach standard aquarium air tubing (not included) to the air outlet on the pump.
- Install Check Valve: Insert the check valve into the air tubing. The check valve prevents water from siphoning back into the air pump during a power outage, protecting the pump from water damage. Ensure the check valve is oriented correctly to allow airflow towards the aquarium.
- Connect Air Stone/Accessory: Attach the other end of the air tubing to an air stone, ornament, or other air-driven aquarium accessory (not included).
- Placement: Position the air pump above the water level of your aquarium. If the pump must be placed below the water level, ensure the check valve is properly installed and functioning to prevent back-siphoning. The flexible rubber feet provide a stable platform and help absorb vibrations.
- Power Connection: Plug the air pump into a suitable electrical outlet.

3. Operating Instructions
Once the air pump is properly set up and connected, it will begin operating immediately upon being plugged into a power outlet. The pump is designed for continuous operation to maintain consistent aeration in your aquarium.
- Power On/Off: The pump does not have an external on/off switch. To operate, plug it into a power source. To turn off, unplug the unit.
- Airflow: The pump provides a steady stream of air to your aquarium. The amount of bubbles produced will depend on the air stone or accessory used.
- Noise Level: The Tetra Whisper Air Pump is engineered for quiet operation, typically producing less than 40 dB of sound. Placing the pump on a soft surface or hanging it can further reduce any audible vibration.

4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your air pump.
- External Cleaning: Periodically wipe the exterior of the pump with a damp cloth to remove dust and debris. Ensure the pump is unplugged before cleaning.
- Air Filter: Check the air intake filter (if accessible) for blockages and clean or replace as needed. A clogged filter can reduce airflow and increase noise.
- Diaphragm Inspection: Over time, the internal diaphragm may wear out, leading to reduced airflow or increased noise. If this occurs, the diaphragm may need to be replaced. Refer to the internal view image for component location.
- Check Valve: Inspect the check valve regularly to ensure it is not clogged and is allowing proper one-way airflow. Replace if damaged or blocked.

5. Troubleshooting
If you encounter issues with your Tetra Whisper Air Pump, consult the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Airflow | Power outage; clogged air tubing/air stone; damaged diaphragm; check valve blockage. | Check power connection; clear tubing/air stone; inspect/replace diaphragm; check check valve for proper function. |
| Low Airflow | Clogged air filter; kinked air tubing; worn diaphragm; pump too far below water level. | Clean/replace air filter; straighten tubing; replace diaphragm; ensure proper check valve installation if below water level. |
| Excessive Noise/Vibration | Pump resting on a hard surface; internal component rubbing; worn diaphragm. | Place pump on a soft surface or hang it; inspect internal components for contact (refer to Video 2); replace diaphragm if worn. |
