Operating Instructions
The Duravit Dura System In-Wall Toilet Tank and Carrier is designed for simple and efficient operation, typically controlled by a dual-flush plate (sold separately) that allows for two different flush volumes.
- Full Flush: Press the larger button or section of the flush plate for a full 1.28 GPF flush, suitable for solid waste.
- Reduced Flush: Press the smaller button or section of the flush plate for a reduced 0.8 GPF flush, suitable for liquid waste, conserving water.
- Ensure the flush plate is properly installed and aligned for optimal functionality.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your Duravit Dura System. Access to internal components is typically through the flush plate opening.
- Cleaning: For external surfaces, wipe with a damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage finishes.
- Inspection: Periodically check for any signs of leaks around connections.
- Internal Components: If issues arise with flushing or water filling, the internal mechanisms can be accessed by removing the flush plate. Refer to specific component manuals for detailed service instructions.
- Winterization: In areas prone to freezing, ensure the water supply to the unit is shut off and the tank is drained if the area is unheated.
Troubleshooting
This section addresses common issues you might encounter with your in-wall toilet system.
- Toilet Not Flushing: Check if the water supply is on. Ensure the flush plate mechanism is correctly engaging the internal flush valve.
- Continuous Running Water: This usually indicates an issue with the fill valve or flush valve seal. Access the tank via the flush plate opening to inspect and adjust or replace components as needed.
- Weak Flush: Verify that the water level in the tank is correct. Check for any obstructions in the flush valve or toilet bowl rim jets.
