Using this soap dispenser is easy. First, if you're using the Multi - Feed system, make sure you've bought the “6 - SOAP - MFT” Soap Multi - Feed Tank separately and filled it. For power, you can either use a Battery pack (4xAA alkaline) or an A/C Adapter. Once it's powered, just wave your hand in front of the dispenser, and the touch - free dual sensors will activate to dispense soap. The indicator light at the base of the spout will show you the power status, when it's activated, and if the soap is running low. As for maintenance, check the soap level regularly and refill when needed. Clean the exterior with a soft, damp cloth to keep the polished chrome finish looking great. Remember, this is a non - returnable item. Also, since it's vandal - resistant, it should hold up well in public or high - traffic areas, but avoid hitting or dropping it to keep all parts in good working order.
