Package Contents

- Stainless Steel Hinges with Soft-Closing Mechanism
- Quick-Release Fasteners
- Installation Hardware (washers, nuts)
Setup and Installation
Follow these steps for proper installation of your toilet seat:
- Prepare the Toilet Bowl: Ensure the toilet bowl is clean and dry. Remove any old toilet seat and hardware.
- Position the Hinges: Place the stainless steel hinges into the mounting holes on the toilet bowl. Ensure the quick-release mechanisms are facing the correct direction (typically towards the back of the bowl).
- Secure the Hinges: From underneath the toilet bowl, attach the washers and nuts to the hinge bolts. Hand-tighten first, then use a wrench to gently secure them. Do not overtighten.
- Attach the Toilet Seat: Align the mounting points on the underside of the toilet seat with the quick-release pins on the hinges. Press down firmly until the seat clicks into place.
- Adjust for Fit: If necessary, the hinges may allow for minor adjustments to ensure the seat is centered on the bowl. Loosen the nuts slightly, adjust, and then re-tighten.
- Test Functionality: Gently lower the seat and lid to confirm the soft-closing mechanism operates smoothly. Test the quick-release function by pressing the release buttons (if applicable) and lifting the seat off.

Operating Instructions
- Soft-Closing Function: To engage the soft-closing feature, simply push the toilet seat or lid down gently. The integrated mechanism will lower it slowly and quietly, preventing slamming. Do not force the seat or lid down manually, as this can damage the soft-closing mechanism.
- Quick-Release Function: For thorough cleaning, the toilet seat can be easily removed. Locate the quick-release buttons or levers near the hinges (specific design may vary). Press or lift these mechanisms, and then lift the entire seat straight up from the toilet bowl. To reattach, align the seat with the hinge pins and press down until it clicks securely into place.
Maintenance and Cleaning
Proper care will ensure the longevity and appearance of your Villeroy & Boch toilet seat:
- Regular Cleaning: Clean the toilet seat regularly with a soft cloth, warm water, and a mild, non-abrasive soap.
- Avoid Harsh Chemicals: Do not use abrasive powders, scouring pads, strong detergents, disinfectants containing chlorine or acid, or aerosol cleaners. These can damage the thermosetting plastic surface and the stainless steel hinges.
- Hinge Care: Periodically check the hinge connections for tightness. If they become loose, gently re-tighten the nuts underneath the toilet bowl.
- Quick-Release Mechanism: Ensure the quick-release mechanism is free of debris to function correctly.
