Setup Guide
Follow these steps to set up your boxtech Aquarium Air Pump:
- Unpack: Carefully remove all components from the packaging.
- Connect Air Tube: Attach one end of the air tube (not included in all packages) to the air outlet nozzle on the pump.
- Install Air Stone: Connect the other end of the air tube to your air stone (not included in all packages).
- Position Air Stone: Place the air stone at the desired location inside your aquarium.
- Pump Placement:
- If possible, place the air pump above the water level of the aquarium. This prevents water from siphoning back into the pump in case of a power outage.
- If the pump must be placed below the water level, you must install a check valve (not included in all packages) in the air tube between the pump and the aquarium. This prevents water backflow and protects the pump from damage.
- Connect Power: Once all connections are secure and the pump is safely positioned, plug the power cord into a suitable electrical outlet.

Operating Instructions
The boxtech Ultra Quiet Aquarium Air Pump operates automatically once connected to power. There are no manual controls on the pump itself for adjusting airflow. If your setup includes a control valve (not included in all packages), you can use it to regulate the air output to your desired level.
- To start the pump, simply plug it into a power outlet.
- To stop the pump, unplug it from the power outlet.
- If using a control valve, rotate the valve to increase or decrease the airflow.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your air pump.
- Air Filter Cleaning: Periodically check the air intake filter at the bottom of the pump for dust or debris. Gently clean it with a soft, dry cloth or a small brush. Do not use water or cleaning agents.
- Air Stone Cleaning/Replacement: Over time, air stones can become clogged, reducing airflow. Clean or replace your air stone as needed to maintain efficient bubbling.
- Tube Inspection: Inspect the air tube for kinks, blockages, or damage. Replace if necessary to ensure unobstructed airflow.
- General Cleaning: Wipe the exterior of the pump with a soft, damp cloth. Ensure no water enters the pump's internal components.
- Storage: If storing the pump for an extended period, clean it thoroughly, disconnect all tubing, and store it in a dry, cool place.
