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 installed it correctly. Fill the soap tank through the top fill port. Select your preferred power supply, either the battery pack (4xAA alkaline) or the A/C Adapter. When you place your hand under the spout, the touch - free dual sensors will detect it and dispense soap. Keep an eye on the indicator light at the base of the spout. It'll let you know if the dispenser is powered, when it's activated, and when the soap is running low. As for maintenance, since it has a vandal - resistant construction, it should be durable. But clean it regularly with a mild cleaner to keep the Brushed Brass finish looking great. Also, make sure to replace the soap when it's low and change the batteries if you're using the battery pack. Remember, this is a non - returnable item, so handle it with care.
