Setup and Installation
Proper installation is critical for the long-term performance and safety of the Geberit Kombifix system. Refer to the diagram below for detailed measurements and connection points.
Figure 1: Geberit Kombifix 110.793.00.1 Installation Diagram. This diagram illustrates the front, top, and side views of the Kombifix chassis with key dimensions and connection points. It shows the concealed cistern within the frame, the water inlet (R 1/2), the waste outlet (Ø 90/90 mm), and the fixing points for the wall-hung WC. Dimensions are provided in centimeters, indicating overall height (109 cm), width (42 cm), and depth (8 cm for the cistern, with adjustable depth for the frame). The diagram also shows the recommended finished floor level (0) and the height for the WC ceramic fixation (41 cm from finished floor).
- Prepare the Installation Area: Ensure the wall structure is suitable for supporting the chassis and a wall-hung WC. The Kombifix is designed for solid or masonry walls.
- Position the Chassis: Place the chassis against the wall at the desired height. The overall height of the frame is 109 cm. Mark the drilling points for secure fastening.
- Secure the Frame: Drill holes and securely fasten the galvanized steel frame to the wall using appropriate fixings. Ensure the frame is level and plumb.
- Connect Water Supply: Connect the R 1/2 water supply to the integrated angle stop valve on the cistern. Ensure all connections are watertight.
- Connect Waste Pipe: Install the Ø 90/90 mm drainage elbow and connect it to the building's waste system. Use the provided set of sleeves for the toilet connection.
- Install Threaded Rods: Insert the M12 threaded rods for ceramic fixation into the designated points on the frame. These will be used to mount the wall-hung WC.
- Cistern Filling and Leak Check: Turn on the main water supply and allow the cistern to fill. Check all connections for leaks. Adjust the water level if necessary using the integrated angle stop valve.
- Concealment: Once all connections are verified and leak-free, the chassis and cistern can be concealed within the wall structure, typically with plasterboard or masonry, leaving access for the flush plate and WC connections.
Operating the Cistern
The Geberit Sigma 8 cm concealed cistern operates in conjunction with a compatible Geberit flush plate (not included). The flush plate activates the flushing mechanism. This model is designed for dual-flush operation, offering options for a full or reduced flush volume to conserve water.
- Flushing: Press the appropriate button on the flush plate to initiate a flush.
- Water Volume Adjustment: The flush volume can be adjusted internally by a qualified technician during installation or maintenance. Refer to the specific flush plate manual for details on its operation.
- Geberit AquaClean Connection: The cistern is prepared for connection to a Geberit AquaClean shower toilet, allowing for integrated functionality.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your Geberit Kombifix system.
- Cleaning: Clean the visible parts of the flush plate and WC ceramic with mild, non-abrasive cleaning agents. Avoid harsh chemicals that could damage surfaces or internal components.
- Access to Cistern: The cistern is designed for concealed installation but allows access for maintenance through the flush plate opening.
- Internal Components: Periodically check the internal components of the cistern (fill valve, flush valve) for wear or blockages. This should ideally be performed by a qualified plumber.
- Leak Detection: If you notice any signs of water leakage, immediately turn off the main water supply and contact a professional plumber.
