Using this soap dispenser is easy. First, if you've chosen the Multi - Feed system, make sure to buy the “6 - SOAP - MFT” Soap Multi - Feed Tank separately and fill it up. If you go for the Single Fill System, just fill at the spout. Power it up with either a 4xAA alkaline battery pack or an A/C Adapter. When you put your hands under the spout, the touch - free dual sensors will detect them and dispense soap. Keep an eye on the indicator light at the spout base. If it shows low soap, it's time to refill. For maintenance, clean the dispenser regularly with a mild cleaner to keep the Brushed Brass finish looking good. Also, check the anti - rotational gasket/washer occasionally to make sure it's in place. And remember, this is a non - returnable item.
