Using the Aquaform Contrast Shower is easy. First, decide whether you want a regular shower, a cold - only experience, or a hot - cold contrast. If you choose a programmed therapy, use the C46 Pro Control Unit to set the hot and cold settings. For a regular shower, simply use the hand shower and select your desired water temperature. When using the aroma system, add your favorite scents according to the instructions. To keep the shower in good condition, clean the square shower head regularly to prevent clogging. Wipe the polished steel finish with a soft cloth to maintain its shine. Make sure to turn off the power and water supply when not in use for a long time. Avoid using harsh chemicals on the shower parts as this may damage them.
