Using this soap dispenser is easy. First, install the power supply, which can be either a 4xAA alkaline battery pack or an A/C adapter. Then, if you're using the Multi - Feed system, make sure you've purchased and connected the “6 - SOAP - MFT” Soap Multi - Feed Tank. The dispenser will activate automatically when it senses your hands under the spout thanks to the touch - free dual sensors. The indicator light at the base of the spout will show you if it's powered, when it's activated, and when the soap is running low. Remember, this is a non - returnable item. When it comes to maintenance, keep the dispenser clean by wiping it regularly with a soft cloth. Avoid using abrasive cleaners that could damage the Brushed Brass finish. Also, make sure to check the anti - rotational gasket/washer periodically to ensure it's in good condition. This dispenser meets ADA guidelines, so use it with confidence knowing it's designed to be accessible for all users.
