The Casta Diva CD-DT002 features an efficient flushing system designed for optimal cleaning with minimal water usage. It typically uses 3-4.5 liters per flush, depending on the cistern settings.
- To flush, activate the flush plate on your concealed cistern (flush plate not included).
- The rimless design ensures water is distributed evenly across the entire bowl for a thorough rinse.

5.2 Soft-Close Seat
The UF toilet seat is equipped with a soft-close mechanism to prevent slamming and reduce noise. Simply push the seat or lid down gently, and it will close slowly and quietly on its own.
6. Maintenance and Cleaning
Regular cleaning and proper maintenance will ensure the longevity and hygienic performance of your toilet.
6.1 General Cleaning
- Use mild, non-abrasive cleaning agents and a soft cloth or sponge.
- For the ceramic bowl, wipe down with a damp cloth and a suitable bathroom cleaner.
- For the UF seat, use a mild soap solution and a soft cloth. Avoid harsh chemicals or abrasive pads, as these can damage the surface.
- Rinse thoroughly with clean water after cleaning.

6.2 Seat Removal for Cleaning
The UF toilet seat features a quick-release mechanism for easy removal, allowing for thorough cleaning of both the seat and the toilet bowl.
- Locate the quick-release buttons or levers near the hinges of the seat.
- Press or lift the mechanisms to detach the seat from the toilet bowl.
- Clean the seat and the hinge area of the toilet bowl separately.
- To reattach, align the seat hinges with the mounting posts and press down until they click into place.
6.3 Preventing Clogs and Limescale
- Avoid flushing non-biodegradable items.
- Regularly clean the toilet bowl to prevent limescale buildup, especially in hard water areas. The wide flow channels are designed to resist clogging and limescale.
