Using this soap dispenser is easy. First, install the dispenser on the counter. If you're using the Multi - Feed system, make sure to buy and install the “6 - SOAP - MFT” Soap Multi - Feed Tank separately. Then, select your power supply, either the battery pack or the A/C adapter. Once it's powered on, the indicator light at the base of the spout will show the power status. When you place your hand under the spout, the touch - free dual sensors will detect it and dispense soap. Note that this is a non - returnable item. For maintenance, regularly check the soap level using the indicator light and refill the soap tank as needed. Clean the dispenser with a soft cloth to keep it looking good. Also, make sure to follow all ADA guidelines during installation and use.
