How It Works

1. Sensor Mounting
   Position the sensor so that your ideal water level sits between the second and third optical sensors.
2. Pump Placement
   Place the DC refill pump in your reservoir; attach the included hose and run it to your aquarium or sump.
3. Power & Go
   Connect the pump and power supply to the sensor module. When water drops below the low-level sensor, the pump turns on and refills until the normal level is reached.
