Using your Linea Series Brushed Bronze Touchless Counter Mounted Sensor Soap Dispenser is easy. First, if you're using the Multi - Feed system, make sure you've purchased and installed the “6 - SOAP - MFT” Soap Multi - Feed Tank. For the power supply, you can either use a 4xAA alkaline battery pack or an A/C Adapter. Just wave your hand in front of the infrared sensor, and the dispenser will release an appropriate amount of liquid soap. When the indicator light at the base of the spout shows low soap, it's time to refill. Remember, this is a non - returnable item. To maintain your dispenser, keep it clean by wiping it with a soft cloth regularly. Avoid using abrasive cleaners that could damage the Brushed Bronze PVD finish. Check the anti - rotational gasket/washer periodically to ensure it's in good condition. This dispenser is designed to be vandal - resistant, but still, try to keep it in a safe place. And since it meets ADA guidelines, it's suitable for a wide range of users.
