3.2. Installation Steps (Professional Installation Recommended)

3. Connect Water Supplies: Connect the hot and cold water supply lines to the designated G 1/2" inlets on the mixer.
4. Connect Outlets: Connect the desired water outlets (e.g., shower head, hand shower, bath spout) to the mixer's G 1/2" outlets.

4. Operating Instructions

The GROHE Rapido T Universal Thermostatic Mixer is operated via a compatible trim set (not included with the concealed unit). The trim set typically includes a temperature control handle and a flow/diverter handle.

• Temperature Control: Rotate the temperature handle to adjust the water temperature. Most GROHE 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 handle.
• Flow Control/Diverter: Use the flow control handle to turn the water on/off and adjust the flow rate. If your trim set includes a diverter, rotate or pull the handle to switch between different water outlets (e.g., overhead shower, hand shower, bath spout).

The GROHE TurboStat technology will maintain the selected temperature even if water pressure fluctuates in your household.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your GROHE Rapido T Universal Thermostatic Mixer.

• Cleaning: Clean the visible parts of the trim set with a soft cloth and mild soap. Avoid abrasive cleaners, scouring pads, or solvents, as these can damage the chrome finish.
• Temperature Calibration: If the water temperature does not match the setting on the handle, the thermostatic cartridge may need recalibration. Refer to the specific instructions for your trim set for this procedure, or contact a qualified plumber.
• Filter Maintenance: The mixer may contain small filters at the inlets to prevent debris from entering the cartridge. If water flow is reduced, these filters may need to be cleaned. This typically requires professional assistance.
• Winterization (if applicable): In areas prone to freezing temperatures, ensure proper winterization procedures are followed to prevent damage to the plumbing system and mixer.
