5.1 Sensor Operation

The faucet is equipped with an infrared sensor for touchless operation. Simply place your hands within the sensor's detection range (typically below the spout) to activate the water flow. Water will stop flowing automatically when your hands are removed from the sensor's range.

5.2 Temperature Adjustment

The faucet includes a mixing device with an adjustable temperature limiter. Use the small lever or knob located on the side of the faucet to adjust the water temperature from cold to hot. The temperature limiter can be set during installation or maintenance to prevent excessively hot water, enhancing safety and energy efficiency.

5.3 Special Functions

• Preset Programs: The faucet comes with 7 preset programs. Refer to the detailed instruction manual included in the package for information on how to access and customize these programs.

6. Maintenance

6.1 Cleaning the Faucet

To maintain the GROHE StarLight chrome surface, clean the faucet regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome finishes. Avoid using abrasive sponges, scouring agents, or cleaners containing alcohol, acid, or ammonia, as these can damage the surface.

6.2 Battery Replacement

The faucet is powered by a 6V lithium battery (type CR-P2) with an approximate life of 7 years under normal usage. The battery level indicator will signal when the battery is low and requires replacement. To replace the battery:

1. Turn off the water supply to the faucet.
2. Locate the battery compartment, usually at the base of the faucet or in a separate control box under the basin.
3. Open the compartment and carefully remove the old battery.
