Adjusting the Water Tank Level
To adjust the water level in the tank:

- Rotate the rod to adjust the height of the floater, which controls the water level (1.6 gal / 6 L).
Maintenance and Care
- Use mild, nonabrasive soap and warm water for general cleaning.
- Do not use abrasive cleaners containing sand or silica, as they will scratch the ceramic finish.
- Do not use in-tank bowl cleaners, as they contain corrosive chemicals that can damage tank components.
