4. Setup and Installation
4.1. Preparation
- Ensure the toilet bowl surface is clean and dry before installation.
- Gather necessary tools: screwdriver (flathead or Phillips, depending on screw type), wrench (if applicable).
4.2. Mounting the Seat (Cavity Fixing)
The LAUFEN Cleanet Navia toilet seat uses a cavity fixing system. Follow these steps for secure installation:
- Position Hinges: Place the hinge bases into the mounting holes on the toilet bowl. Ensure they are aligned correctly with the bowl's edge.
- Insert Screws: Insert the mounting screws through the hinge bases and into the toilet bowl's mounting cavities.
- Secure Fasteners: From underneath the toilet bowl (if accessible) or by tightening from the top (for top-fix systems), secure the screws with the provided washers and nuts. Tighten firmly but do not overtighten to avoid damaging the ceramic.
- Attach Seat: Align the toilet seat's attachment points with the hinge posts. Press down firmly until the seat clicks into place. This indicates it is securely attached.
- Test Stability: Gently try to move the seat to ensure it is stable and does not wobble. Adjust hinge positions or tighten screws if necessary.

5.2. Removing the Seat for Cleaning
For thorough cleaning of the toilet bowl and seat, the LAUFEN Cleanet Navia seat can be easily removed:
- Open Lid and Seat: Lift both the toilet seat and lid to their fully upright positions.
- Locate Release Buttons: On the underside of the seat, near the hinges, locate the quick-release buttons or levers. These may vary slightly in design.

- Reattachment: To reattach, align the seat's attachment points with the hinge posts and press down until it clicks securely into place.
6. Maintenance and Cleaning
Proper care will extend the life and maintain the appearance of your toilet seat:
- Regular Cleaning: Clean the seat and lid regularly with a soft cloth and mild soapy water.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, strong acids, alkalis, or chlorine-based products, as these can damage the plastic surface and hinge mechanisms.
- Drying: After cleaning, wipe the seat and hinges dry with a soft cloth to prevent water spots and mineral buildup.
- Hinge Care: Periodically check the hinge connections for tightness. If they become loose, gently retighten the mounting screws.
