Setup Instructions
- Placement: Position the pump in the desired location within your water feature, aquarium, or hydroponic system. Ensure it is fully submerged in water. The integrated suction cups on the bottom of the pump can be used to secure it firmly to a smooth surface.

Maintenance
Regular maintenance will ensure the longevity and efficient operation of your ViaAqua VA180 pump.
- Disconnect Power: Always unplug the pump before performing any maintenance.
