2. Setup Instructions

Follow these steps to properly set up your hygger aquarium air pump:

Connect the air tubing (not included) to the pump's outlets.
Install a check valve in the airline tubing to prevent water back-siphoning into the pump during power outages.
Connect the other end of the tubing to air stones, ornaments, sponge filters, or other aeration equipment in your aquarium.
Place the air pump in a fixed, stable position. Ensure the pump is placed above the water level of your aquarium. If this is not possible, the check valve is crucial to prevent water damage to the pump.
Plug the power cord into a suitable electrical outlet.

3. Operating Instructions

Once the pump is set up and plugged in, it will begin to operate. Use the adjustable flow knob to control the air output.

Adjusting Airflow:

Locate the control knob on the front of the air pump. Rotate the knob clockwise to increase airflow and counter-clockwise to decrease airflow. Adjust the flow to meet the specific needs of your aquarium and connected devices.

4. Maintenance

Regular maintenance ensures the longevity and optimal performance of your air pump. The most common wear part is the diaphragm.

Diaphragm Replacement:

If the air pump experiences a sudden loss of power or one side stops working, it may indicate a torn diaphragm. The diaphragm inside the air pump moves back and forth, and prolonged use can cause it to wear out.

To resolve this, disassemble the air pump and replace the damaged diaphragm with a new one.
Ensure that the air tubing is not blocked, pinched, or that the connected accessories are not restricting airflow. Back-pressure can damage the diaphragms.
Do not run the pump without hoses attached, as this can also lead to diaphragm damage.

5. Troubleshooting

If you encounter issues with your air pump, refer to the following common problems and solutions:

No Air Output or Weak Airflow:
- Check if the power cord is securely plugged in.
- Ensure the adjustable flow knob is not set to the lowest setting.
- Inspect the air tubing for kinks, blockages, or leaks.
- Verify that air stones or other connected devices are not clogged. Clean or replace them if necessary.
- Refer to the Maintenance section for diaphragm inspection and replacement if the issue persists.
Excessive Noise:
- Ensure the pump is placed on a stable, flat surface.
- Check that the rubber feet are intact and properly cushioning the pump.
- Verify that the pump is not touching any other objects that could amplify vibrations.
- If the noise is a rattling sound, the internal components might be loose or a diaphragm might be damaged (refer to Maintenance).
Water Back-siphoning into Pump:
- Immediately unplug the pump.
- Ensure a check valve is installed correctly in the airline tubing.
- If the pump was below water level, reposition it above the water level or ensure the check valve is functioning properly.
