Setup and Installation
Follow these steps for proper installation of your toilet seat:
- Prepare the Toilet: Ensure the toilet bowl is clean and dry where the seat will be mounted. Remove any old toilet seat and hardware.
- Position the Hinges: Place the stainless steel hinges into the mounting holes on the toilet bowl.
- Attach the Seat: Align the toilet seat with the hinges. The QuickRelease mechanism allows for easy attachment. Press down firmly until the seat clicks into place.
- Adjust and Secure: Adjust the position of the seat to ensure it is centered on the toilet bowl. Tighten the mounting screws from underneath the toilet bowl to secure the hinges firmly. If your toilet does not allow access from underneath, ensure the top-fix mechanism is securely fastened.

Operating Instructions
Your Villeroy & Boch Avento toilet seat is designed for ease of use and enhanced comfort.
Soft-Close Mechanism
The integrated soft-close mechanism ensures that the toilet lid and seat close gently and silently. To operate, simply push the lid or seat downwards; it will lower slowly and quietly on its own. This prevents slamming, reduces noise, and protects the product from wear and tear.

QuickRelease Function
The QuickRelease function allows for easy removal of the toilet seat from the hinges for thorough cleaning. To remove, simply pull the seat upwards from the hinges. To reattach, align the seat with the hinges and press down until it clicks securely into place.
Maintenance and Cleaning
Regular cleaning will maintain the hygiene and appearance of your toilet seat. The Duroplast material and non-porous surface are designed for easy care.
- Daily Cleaning: Use a soft cloth with mild soap and water. Wipe down all surfaces of the seat and lid.
- Deep Cleaning: For a more thorough clean, utilize the QuickRelease function to remove the seat. This allows access to hard-to-reach areas around the hinges and toilet bowl. Clean the seat and hinges separately with mild soap and water, then reattach.
- Avoid: Do not use abrasive cleaners, scouring pads, strong acids, or alkaline cleaning agents, as these can damage the Duroplast surface and the soft-close mechanism.
- Drying: Always dry the seat and hinges thoroughly after cleaning to prevent water spots and maintain hygiene.

Troubleshooting
If you encounter any issues with your Villeroy & Boch Avento toilet seat, please refer to the following common solutions:
- Seat is loose: Check if the mounting screws underneath the toilet bowl (or top-fix mechanism) are securely tightened. If the QuickRelease mechanism is not fully engaged, remove and reattach the seat firmly until it clicks.
- Soft-close not working properly: Ensure the hinges are clean and free from debris. If the issue persists, the soft-close mechanism might be worn. Contact customer support for assistance.
- Seat does not fit: Verify that your toilet bowl is compatible with a D-shape seat and that the dimensions match those specified for the Avento model. Refer to the "Setup and Installation" section and the provided dimension image.
