5. Operating Instructions
5.1 Dispensing Hot and Cold Water
The single-handle lever controls the flow and temperature of regular hot and cold water. Move the lever to the left for hot water and to the right for cold water. Adjust the lever position to achieve the desired temperature and flow rate.
5.2 Dispensing Boiling Water (Child Lock)
The GROHE Red system features a child lock for safe dispensing of boiling water. To dispense boiling water:
- Activate the child lock mechanism (refer to the specific instructions provided with your faucet for exact operation, typically a push-and-turn or pull-and-hold action on a dedicated control).
- Once activated, boiling water will flow from the C-spout.
- Release the control to stop the flow of boiling water.
The GROHE CoolTouch® technology ensures the faucet body remains cool to the touch, even when dispensing boiling water, enhancing safety.
6. Maintenance
6.1 Cleaning the Faucet
The GROHE StarLight® chrome finish is durable and easy to clean. Use only mild soap and water with a soft cloth. Avoid abrasive cleaners, scouring pads, or chemical solvents, as these can damage the finish.

The GROHE Blue filter cartridge requires regular replacement to maintain water quality and system performance. The frequency of replacement depends on water hardness and usage. Refer to the filter's specific instructions for replacement procedures and indicators.
