4. Setup & Installation
Follow these steps to properly install your Duravit D-Neo toilet seat.
- Prepare the Toilet Bowl: Ensure the toilet bowl's mounting holes are clean and free of debris. Remove any old toilet seat and hardware.
- Insert Mounting Bolts: Place the rubber washers over the mounting holes on the toilet bowl. Insert the threaded bolts of the hinge assembly through the washers and holes.
- Attach Hinges to Seat: Align the hinge posts with the corresponding holes on the underside of the toilet seat. Secure the hinges to the seat using the provided screws, ensuring they are snug but not overtightened.
- Position the Seat: Carefully lower the toilet seat onto the toilet bowl, guiding the hinge bolts through the mounting holes.
- Secure the Seat: From underneath the toilet bowl, place the plastic washers and then the nuts onto the threaded bolts. Hand-tighten the nuts initially to allow for adjustment.
- Adjust and Finalize: Adjust the seat position to ensure it is centered and aligned with the toilet bowl. Once aligned, fully tighten the nuts with a wrench. Do not overtighten.

5. Operating Instructions
The Duravit D-Neo toilet seat features a soft-close mechanism for both the seat and the lid, designed to prevent slamming and reduce noise.
- Soft-Close Function: To engage the soft-close feature, simply push the seat or lid down gently. The mechanism will take over, allowing it to close slowly and quietly on its own.
- Do not force the seat or lid closed, as this can damage the soft-close mechanism over time.

6. Maintenance & Cleaning
Regular cleaning and proper maintenance will help preserve the appearance and functionality of your toilet seat.
- Daily Cleaning: Use a soft cloth dampened with mild soap and water to wipe down the seat and lid.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, strong detergents, disinfectants containing chlorine, or aerosol cleaners. These can scratch the surface, dull the finish, or damage the soft-close mechanism.
- Drying: Always dry the seat thoroughly with a soft, clean cloth after cleaning to prevent water spots.
- Hinge Care: Periodically check the hinge connections for tightness. If the seat feels loose, gently tighten the mounting nuts.
