3.3 Installation Steps
Follow these steps for proper installation of the Duravit 2x4 Installation Frame with Concealed Tank:
- Prepare the Installation Area: Ensure the wall structure is suitable for supporting the frame and a wall-hung toilet. Mark the desired height and center line for the toilet.
- Mount the Frame: Position the installation frame against the wall studs. Use a level to ensure it is perfectly vertical and horizontal. Secure the frame to the wall studs using appropriate fasteners. Adjust the frame's feet to the desired height and secure them to the floor.
- Connect Water Supply: Connect the water supply line to the concealed tank's inlet valve. Ensure all connections are tight and leak-free.
- Connect Waste Outlet: Connect the tank's waste outlet to the building's drainage system. Verify proper alignment and secure all connections.
- Test for Leaks: Turn on the main water supply and allow the tank to fill. Carefully inspect all water connections for any signs of leaks. Address any leaks immediately.
- Install Wall Covering: Once the frame and tank are securely installed and tested, you can proceed with installing the wall covering (e.g., drywall, tile) over the frame, leaving access for the flush plate and toilet mounting points.

4. Operation
The Duravit 111728001 installation frame is designed to support a wall-hung toilet and house a concealed tank. Operation primarily involves the flush mechanism, which is activated by a compatible flush plate (sold separately) installed on the finished wall. The tank provides a dual-flush option for water conservation, typically with a full flush and a reduced flush volume.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your concealed tank system:
- Cleaning: Clean the visible parts of the flush plate and toilet regularly with mild, non-abrasive cleaners. Avoid harsh chemicals that could damage finishes.
- Leak Checks: Periodically check for any signs of leaks around the toilet and access panel.
- Internal Components: If issues arise with flushing, the internal components of the tank can be accessed via the flush plate opening. Consult a professional for internal repairs if necessary.
- Water Quality: In areas with hard water, mineral deposits may accumulate over time. Regular flushing and occasional inspection can help prevent issues.
6. Troubleshooting
Refer to the table below for common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tank not filling | Water supply turned off; Inlet valve clogged or faulty | Check water supply; Clean or replace inlet valve. |
