Using this soap dispenser is easy. First, choose your power source, either the battery pack or the A/C adapter. Then, fill the 70.5oz soap tank at the top of the spout with non-proprietary bulk foam soap. When you place your hand under the dispenser, the touch-free dual sensors will activate and dispense soap. The indicator light at the base of the spout will let you know if it's powered, if it's activated, and when the soap is running low. As for maintenance, keep it clean by wiping it with a soft cloth regularly. Since it has a vandal-resistant construction, it should hold up well. But avoid using harsh chemicals on the brushed bronze PVD finish as it could damage the surface. And remember, this is a non-returnable item.
