5.1 Thermostatic Mixer
- Temperature Control: Use the temperature knob (typically on the right) to set your desired water temperature. The thermostatic cartridge will automatically mix hot and cold water to maintain this temperature, even if water pressure fluctuates.
- Safety Stop: Most thermostatic mixers have a safety stop button, usually at 38°C (100°F), to prevent accidental scalding. Press this button to increase the temperature beyond 38°C.
- Flow Control: Use the flow control knob (typically on the left) to adjust the water volume.
5.2 Diverter (Head Shower / Hand Shower)
The diverter allows you to switch the water flow between the large overhead head shower and the flexible hand shower.
- Rotate or pull the diverter knob/lever to select your preferred shower outlet.
5.3 Hand Shower Functions
The hand shower features 3 different spray functions for a personalized showering experience.
- Rotate the spray plate on the hand shower head to cycle through the available spray patterns (e.g., rain, massage, mixed).

6. Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your shower column.
6.1 Cleaning Chrome Surfaces
- Clean chrome surfaces regularly with a soft cloth and mild soap or a non-abrasive bathroom cleaner.
- Avoid using abrasive sponges, scouring pads, or harsh chemical cleaners (e.g., bleach, acid-based cleaners) as these can damage the chrome finish.
- Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
6.2 Descaling Shower Heads
- Over time, limescale can build up in the nozzles of the head shower and hand shower, affecting spray performance.
- Many shower heads feature flexible silicone nozzles that can be easily cleaned by gently rubbing them with your finger to dislodge scale.
- For more stubborn deposits, soak the shower head in a descaling solution (e.g., white vinegar diluted with water) for a few hours, then rinse thoroughly.
7. Troubleshooting
If you encounter any issues with your shower column, refer to the following common troubleshooting tips. For complex problems, contact a qualified plumber.
7.1 Low Water Pressure
- Check Water Supply: Ensure main water valves are fully open.
- Clean Shower Heads: Limescale buildup can restrict flow. Clean the nozzles as described in the Maintenance section.
- Check Filters: Some mixers have inlet filters that can become clogged. Consult a professional for cleaning or replacement.
7.2 Inconsistent Water Temperature
- Check Hot Water Supply: Ensure your hot water heater is functioning correctly and providing sufficient hot water.
- Thermostatic Cartridge: A faulty or scaled thermostatic cartridge can cause temperature fluctuations. This typically requires professional inspection and replacement.
- Water Pressure Imbalance: Significant pressure differences between hot and cold water lines can affect thermostatic performance.
7.3 Leaks
- Check Connections: Ensure all connections (hose, shower heads, mixer inlets) are securely tightened and properly sealed with gaskets.
- Damaged Gaskets/O-rings: Worn or damaged gaskets/O-rings can cause leaks. These may need to be replaced.
- Internal Leaks: Leaks from within the mixer body or column may indicate internal component failure and require professional service.
