5.3 Mounting the Sink
- For Vanity Installation: Apply a bead of silicone sealant along the top edge of the vanity cabinet where the sink will rest. Carefully lower the sink onto the vanity, aligning it properly.
- For Wall-Mounted Installation: Mark the mounting points on the wall using the sink's dimensions and a level. Drill pilot holes and secure the mounting brackets (if applicable) or bolts into wall studs or appropriate anchors. Carefully lift the sink and secure it to the wall using the provided hardware.
5.4 Faucet and Drain Installation
- Install the faucet according to the manufacturer's instructions, securing it through the pre-drilled hole in the sink.
- Install the drain assembly into the sink's drain opening, using plumber's putty or silicone sealant under the flange to create a watertight seal. Connect the P-trap to the drain assembly and the wall drain pipe.
- Connect the hot and cold water supply lines to the faucet and the corresponding shut-off valves.
5.5 Leak Testing
- Once all connections are made, slowly turn on the water supply.
- Check all connections for leaks. Tighten any leaking connections gently.
- Fill the sink with water and then drain it, observing the drain assembly and P-trap for any leaks.
6. Operating Instructions
The Duravit D-Neo Vanity Sink operates like any standard bathroom sink. Turn the faucet handles to control water flow and temperature. The integrated overflow is designed to prevent minor overfilling, but it is not a substitute for supervision.
7. Maintenance
7.1 Cleaning
To maintain the appearance and longevity of your ceramic sink:
- Clean regularly with a soft cloth and mild, non-abrasive cleaner.
- Wipe with a dry cloth after cleaning to prevent water spots and mineral buildup.
- Avoid using harsh chemicals, abrasive cleaners, scouring pads, or steel wool, as these can damage the ceramic surface.
- For stubborn stains, consult the Duravit website for specific ceramic care recommendations.
7.2 Drain Maintenance
Periodically remove and clean the drain stopper to prevent hair and debris buildup that can lead to clogs.
