4.4 Post-Installation
- Slowly turn on the main water supply.

5. Operating Instructions
Your Roca Deck Thermostatic Shower Column is designed for ease of use and precise temperature control.
5.1 Temperature Control
- The thermostatic mixer features a temperature control lever, typically on the right side.
- Rotate the lever to adjust the water temperature. Most thermostatic mixers have a safety stop at 38°C (100°F) to prevent accidental scalding. To exceed this temperature, press the safety button and continue rotating the lever.
- The thermostatic cartridge will automatically mix hot and cold water to maintain the selected temperature, even if water pressure fluctuates.
5.2 Water Flow and Diverter
- The flow control lever, typically on the left side, allows you to turn the water on/off and adjust the flow intensity.
- The diverter control, often integrated into the flow lever or as a separate knob, allows you to switch between the overhead shower and the hand shower.
5.3 Hand Shower Functions
The 130 mm hand shower offers multiple spray patterns. Rotate the spray plate on the hand shower head to select your desired function.
6. Maintenance and Cleaning
Regular cleaning and maintenance will ensure the longevity and optimal performance of your Roca shower column.
6.1 Cleaning the Chrome Finish
- Clean the chrome surfaces with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome fixtures.
- Rinse thoroughly with clean water and dry immediately with a soft cloth to prevent water spots.
- Avoid using abrasive sponges, scouring pads, or cleaners containing harsh chemicals, acids, or ammonia, as these can damage the finish.
6.2 Cleaning Shower Heads
- The nozzles on both the overhead and hand shower heads are designed for easy cleaning. Gently rub the silicone nozzles to dislodge any limescale buildup.
- For more stubborn limescale, use a descaling solution suitable for shower fixtures, following the manufacturer's instructions.
