2.3 Installation Steps
- Prepare the Flange: Install new flange bolts into the floor flange.

- Position the Toilet: Carefully lower the toilet onto the flange bolts, ensuring the wax ring creates a seal. Press down firmly and evenly.
- Secure the Toilet: Hand-tighten the nuts onto the flange bolts. Alternate tightening each nut a quarter turn at a time to prevent cracking the ceramic. Do not overtighten. Install bolt caps.

3. Operating Instructions
3.1 Dual Flush Mechanism
The Duravit DuraStyle toilet is equipped with a dual flush system designed to conserve water. The flush button on top of the tank typically features two distinct sections or buttons:
- Small Button/Section: Activates a partial flush (0.8 gallons) for liquid waste, using less water.
- Large Button/Section: Activates a full flush (1.6 gallons) for solid waste, providing maximum clearing power.
Press the appropriate button firmly and release. The tank will refill automatically after each flush.
4. Care and Maintenance
Regular cleaning and proper maintenance will ensure the longevity and hygienic performance of your Duravit toilet.
4.1 Cleaning Instructions
- Use mild, non-abrasive cleaners and a soft cloth or sponge for daily cleaning.
- Avoid harsh chemicals, abrasive powders, or scouring pads, as these can damage the ceramic surface and finish.
- For stubborn stains, use a toilet bowl cleaner specifically designed for ceramic fixtures, following the product's instructions carefully.
- Rinse thoroughly with clean water after cleaning to remove all cleaner residue.
- Clean the exterior, including the base and tank, regularly to maintain appearance.
4.2 Hygiene Glaze Technology
Some Duravit toilets feature Hygiene Glaze, an antibacterial ceramic glaze that inhibits the growth of bacteria and germs. If your model includes this feature, it contributes to a more hygienic surface, making cleaning easier. However, regular cleaning as described above is still necessary to maintain optimal hygiene.

5. Troubleshooting
This section addresses common issues you might encounter. For problems not listed here or if solutions do not resolve the issue, please contact customer support.
- Weak Flush:
- Ensure the water supply valve is fully open.
- Check the water level in the tank; it should be at the marked waterline.
- Inspect the flush valve and flapper for obstructions or damage.
- Continuous Running Water:
- Check the flapper or flush valve for proper seating and seal.
- Ensure the fill valve is not overfilling the tank, causing water to spill into the overflow tube. Adjust the fill valve if necessary.
- Leaks:
- Inspect all connections (supply line, tank-to-bowl bolts, wax ring) for tightness. Do not overtighten ceramic connections.
- If leaking from the base, the wax ring may need replacement.
