4. Installation Guide
This section provides a general overview of the installation process. For detailed, step-by-step instructions, please refer to the specific installation manual provided with the product or consult a qualified professional.
- Preparation: Turn off the main water supply. Ensure the installation area is clean and clear. Gather all necessary tools and materials.
- Wall Opening: Create an appropriate opening in the wall for the flush-mounted unit. The installation depth should be between 65 mm and 95 mm. Refer to the technical drawing for precise dimensions.
- Mounting the Basic Body: Securely mount the basic body of the Keuco IXMO Solo 59554 unit within the wall opening. Ensure it is level and properly aligned.
- Water Connections: Connect the hot and cold water supply lines to the designated inlets on the functional unit. The unit includes a DN 15 hose connection. Ensure all connections are sealed properly to prevent leaks.
- Pressure Testing: After all connections are made, slowly turn on the main water supply and check for any leaks. Address any leaks immediately.

5. Operation
The Keuco IXMO Solo 59554 functional unit works in conjunction with a compatible thermostatic trim set to control water temperature and flow. Once the trim set is installed, operation typically involves:
- Temperature Control: Rotate the temperature control handle on the trim set to adjust the water temperature. Thermostatic valves maintain a consistent temperature even with fluctuations in water pressure.
- Flow Control: Use the flow control handle (if present on the trim set) to adjust the water volume.
- Safety Stop: Most thermostatic valves include a safety stop, usually at 38°C (100°F), to prevent accidental scalding. This can typically be overridden by pressing a button or switch on the trim set while turning the handle.
Refer to the specific user manual for your chosen Keuco IXMO Solo trim set for detailed operating instructions.
6. Care and Maintenance
Proper care and maintenance will ensure the longevity and optimal performance of your Keuco IXMO Solo functional unit and its associated trim set.
- Cleaning: Clean the visible parts of the trim set regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for bathroom fixtures.
- Avoid Harsh Chemicals: Do not use abrasive sponges, scouring pads, or cleaners containing alcohol, ammonia, bleach, or phosphoric acid, as these can damage the surface finish.
- Rinsing: Always rinse thoroughly with clean water after cleaning and dry with a soft cloth to prevent water spots.
- Internal Components: The concealed functional unit generally requires no user maintenance. If issues arise, consult a qualified plumber.
