2. Safety Information
Please observe the following safety precautions during installation and use:
- Always turn off the water supply to the toilet before beginning any installation or maintenance work.
- Wear appropriate personal protective equipment (PPE) such as gloves and eye protection during installation.
- The toilet is heavy. Use proper lifting techniques or seek assistance to prevent injury.
- Ensure all connections are secure and watertight to prevent leaks.
- Do not use abrasive cleaners or tools that could damage the toilet's surface or HygieneGlaze coating.
- Keep small parts out of reach of children.
3. Setup and Installation
This section outlines the general steps for installing your Duravit No.1 One-Piece Toilet. Professional installation is recommended.
3.1. Required Tools and Materials (Not Included)
- Adjustable wrench
- Screwdriver (Phillips and flathead)
- Putty knife
- Measuring tape
- Level
- Wax ring with flange or rubber seal
- Toilet supply line
- Caulk gun and silicone sealant
3.2. Installation Steps
- Prepare the Area: Turn off the water supply to the existing toilet and flush to empty the tank. Disconnect the supply line and remove the old toilet. Clean the flange area thoroughly.
- Install Wax Ring/Seal: Place a new wax ring with a plastic horn or a rubber seal onto the closet flange on the floor. Ensure it is centered.
- Position the Toilet: Carefully lift the Duravit No.1 One-Piece Toilet and align the bolt holes on the toilet base with the closet bolts on the flange. Gently lower the toilet onto the wax ring/seal.
- Secure the Toilet: Install the washers and nuts onto the closet bolts. Tighten the nuts alternately until the toilet is snug and stable, but do not overtighten, as this can crack the ceramic.
- Connect Water Supply: Connect the flexible water supply line from the shut-off valve to the fill valve inlet on the toilet tank. Hand-tighten, then use a wrench for a final quarter-turn.
- Restore Water Supply and Check for Leaks: Turn on the water supply slowly and allow the tank to fill. Check all connections for leaks. Flush the toilet several times to ensure proper operation and check for any further leaks.
- Apply Caulk (Optional): For a finished look and to prevent water from collecting under the base, apply a bead of silicone caulk around the base of the toilet where it meets the floor. Leave a small gap at the back for ventilation.
4. Operating Instructions
The Duravit No.1 One-Piece Toilet is designed for simple and efficient operation.
- Flushing: To flush the toilet, press the flush button located on the top of the tank. This model typically features a dual-flush mechanism. Press the smaller button for a liquid waste flush and the larger button for a solid waste flush to conserve water.
- HygieneGlaze: Your toilet is equipped with HygieneGlaze, an innovative ceramic glaze that is antibacterial and highly effective in inhibiting the growth of bacteria and germs. This contributes to a cleaner and more hygienic toilet surface.
5. Maintenance and Care
Proper care will ensure the longevity and performance of your Duravit No.1 Toilet, especially maintaining the effectiveness of the HygieneGlaze.
- Regular Cleaning: Clean the toilet regularly with a soft cloth or sponge and a mild, non-abrasive bathroom cleaner.
- HygieneGlaze Care: To preserve the HygieneGlaze coating, avoid using harsh chemicals, abrasive cleaners, scouring pads, or strong acids/alkalis. These can damage the glaze and reduce its antibacterial properties.
- Toilet Seat: Clean the plastic toilet seat with mild soap and water. Do not use harsh chemicals, as they can discolor or damage the seat material.
- Internal Components: Periodically check the fill valve and flush valve for proper operation and wear. If issues arise, consult a plumber or refer to specific component manuals.
6. Troubleshooting
Refer to the following table for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Toilet runs continuously | Flapper not sealing, fill valve out of adjustment, or debris in valve. | Check flapper for proper seating and wear. Adjust fill valve water level. Clean any debris from the fill valve. |
| Weak flush | Low water level in tank, clogged rim jets, or partial clog in trapway. | Adjust fill valve to increase water level. Clean rim jets under the bowl rim. Use a toilet auger to clear trapway. |
| Leaking at base | Loose closet bolts, faulty wax ring/seal, or cracked toilet base. | Tighten closet bolts (do not overtighten). Replace wax ring/seal. If cracked, the toilet may need replacement. |
| Slow tank refill | Partially closed water supply valve or clogged fill valve. | Ensure water supply valve is fully open. Clean or replace fill valve if clogged. |
If these solutions do not resolve the issue, please contact Duravit customer support or a qualified plumber.
