5. Operating Instructions
Your GROHE Blue Pure Eurosmart Duo tap provides both regular tap water and filtered drinking water.
5.1. Dispensing Unfiltered Water
Use the main single-lever handle for regular hot and cold tap water. Move the handle left or right to adjust temperature and up or down to control flow.
5.2. Dispensing Filtered Water
The separate handle on the side of the tap is dedicated to filtered water. Turn this handle to dispense filtered water. The internal waterways ensure that filtered water remains separate from unfiltered water.
