Using this soap dispenser is easy. First, make sure you've purchased and installed the “6 - SOAP - MFT” Soap Multi - Feed Tank if you're using the Multi - Feed system. Then, select your power source, 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. The indicator light at the base of the spout will let you know if there's power, if the dispenser is activated, and when the soap is running low. Remember, this is a non - returnable item. For maintenance, regularly check the soap level and refill the tank as needed. Also, clean the dispenser with a soft cloth to keep its brushed stainless steel finish looking great. Ensure that the anti - rotational gasket/washer is in place to maintain its vandal - resistant construction. And always follow the ADA guidelines when installing and using the dispenser.
