Consideracions clau per a la instal·lació:
- Wall Framing: Ensure the wall framing is adequately prepared to accommodate the system's dimensions (approximately 5.5"D x 19.75"W x 49"H). Doubling up studs on the sides can enhance stability.
- Compatibilitat: The system is designed for 2-hole wall-hung wash-down WCs with 7.1-inch or 9.1-inch fastening distances. It fits toilet heights ranging from 15 to 19 inches.
- Components addicionals necessaris: The in-wall system does not include all necessary components for a complete toilet installation. Users must acquire:
- An actuator plate (flush plate) – available in various styles and colors.
- Acoustic insulation bowl connection set (e.g., Geberit 156.050.00.1) to reduce sound transmission.
- Connecting pipes and other plumbing accessories as required by local codes and specific toilet bowl.

Instruccions de funcionament
The Geberit DuoFix In-Wall System operates in conjunction with a compatible wall-hung toilet bowl and an actuator plate (flush plate).
- Dual Flush Mechanism: The system features a dual-flush mechanism, allowing users to select between a full flush (1.6 Gallons per Flush - GPF) and a reduced flush volume for liquid waste. This promotes water conservation. The specific operation of the dual flush is controlled by the design of the chosen actuator plate.
- Alçada ajustable: The system includes height-adjustable feet, allowing for customization of the toilet bowl height during installation to suit personal preference and accessibility requirements.
Manteniment
The concealed nature of the Geberit DuoFix system simplifies external cleaning, as there is no visible tank or pipework. Maintenance of the internal components is facilitated through the actuator plate opening.
- Access to Internal Components: The internal tank components, such as the fill valve and flush valve, are accessible by removing the actuator plate. This design allows for inspection, cleaning, or replacement of parts without needing to open the wall.
- Neteja regular: While the tank is concealed, regular cleaning of the toilet bowl and the visible actuator plate is recommended using standard bathroom cleaning agents. Avoid abrasive cleaners on the actuator plate.
Resolució de problemes
Should you encounter issues with your Geberit DuoFix In-Wall System, consider the following common troubleshooting steps:
- Aigua corrent contínua: If water continuously runs into the toilet bowl, this often indicates an issue with the flush valve or fill valve inside the tank.
- Remove the actuator plate to access the tank's internal mechanisms.
- Inspect the flush valve for any obstructions or misalignments that prevent it from sealing properly.
- Check the fill valve for proper operation and ensure the water level is not too high, causing overflow into the flush mechanism.
- Incomplete Flush: If the toilet does not flush effectively, ensure the water supply to the tank is fully open and that the actuator plate is correctly engaging the flush mechanism.
- Peces que falten o danyades: If components appear to be missing or damaged upon receipt or during installation, contact the supplier or manufacturer for assistance. Ensure all required additional components (actuator plate, acoustic insulation, connecting pipes) have been acquired.
For complex issues or if basic troubleshooting does not resolve the problem, it is advisable to consult a qualified plumber or refer to the detailed troubleshooting section in the official installation manual.
