Using this soap dispenser is easy. First, if you've chosen the Multi - Feed system, make sure you've bought the “6 - SOAP - MFT” Soap Multi - Feed Tank separately and installed it properly. Then, select your preferred power supply, either the 4xAA alkaline battery pack or the A/C Adapter. Once powered, just place your hands under the spout, and the touch - free dual sensors will detect your hands and dispense foam soap. Keep an eye on the indicator light at the base of the spout. If it shows low soap, it's time to refill. For maintenance, regularly clean the dispenser with a mild soap and water solution. Don't use abrasive cleaners as they can damage the Brushed Stainless Steel PVD finish. Also, check the anti - rotational gasket/washer periodically to ensure it's in good condition. Remember, this is a non - returnable item, so make sure it meets your needs before purchase.
