TROUBLESHOOTING GUIDE:
Care and Cleaning Instructions:
• Do not use any abrasive or chemical cleaners to clean the faucets.
• If abrasives or chemicals are used it can lead to dulling of luster, attacking of chrome plating or decorative finishes.
• ONLY use mildly warm soapy water, and then wipe the device dry with a clean/soft towel or cloth.
• Upon cleaning other areas of the restroom be sure the sensor lenses are protected from other cleaning chemicals/solvents to prevent
potential damages to the sensor and/or electronics.
