- The frame has holes with a diameter of 9 mm for fixing to construction with a wooden panel, if applicable.
- Leg Adjustment:
- Adjust the galvanized legs to the required height (0-20 cm), using the position marks for accuracy.
- If installing on a finished floor, the support legs are retractable by 5 cm.
- Wall Fixing:
- Secure the frame to the wall using the provided fixing material.
- For UW 50 and UW 75 profiles, utilize the adjustable support plate for secure installation.
- The frame can be tabicared at partial height or full height.
- Plumbing Connections:
- Connect the two R 1/2" connections for water supply.
- Install the ø 50 mm drain elbow and the ø 44/40 mm gasket for waste water.
- Ensure all connections are tight and leak-free.
- Bidet Mounting:
- Once the frame is securely installed and plumbing is complete, mount the bidet using the two M12 threaded rods for ceramic fixing.
- Ensure the bidet is level and securely fastened to the frame.
- This frame is suitable for bidets with countertop faucets.
5. Operation
The Geberit Duofix Bidet Frame functions as a robust and stable support system for your wall-mounted bidet. Once installed, its operation is integrated with the bidet itself. The frame ensures the bidet is securely anchored to the wall, providing stability and allowing for proper water supply and drainage through the connected plumbing.
There are no user-operable parts on the frame itself after installation. All bidet functions (water flow, temperature, etc.) are controlled directly via the bidet's fixtures.
6. Maintenance
Regular maintenance of the Geberit Duofix Bidet Frame is minimal, as it is primarily a structural component. However, periodic checks are recommended to ensure longevity and proper function:
- Cleaning: If the frame is exposed (e.g., during construction or before final wall covering), clean it with a damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the blue primer or galvanized surfaces.
- Leak Checks: Periodically inspect all plumbing connections for any signs of leaks. Address any leaks immediately to prevent water damage.
- Structural Integrity: Ensure that the bidet remains firmly attached to the frame and that the frame itself shows no signs of loosening from the wall or floor.
- Component Inspection: Check for any visible damage or corrosion on the frame or its components. While the frame is designed for durability, extreme conditions or improper installation can affect its integrity.
