Using this soap dispenser is easy. First, make sure you've purchased the '6-SOAP-MFT' Soap Multi-Feed Tank if you're using the Multi-Feed system. Then, choose 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 status. When you place your hand under the spout, the touch-free dual sensors will detect it and dispense the foam soap. Be aware that this is a non-returnable item. For maintenance, keep an eye on the indicator light for low soap levels and refill the tank as needed. The dispenser has a vandal-resistant construction, but try to avoid rough handling. It complies with ADA guidelines, so use it in accordance with those regulations. And remember, it's compatible with non-proprietary bulk foam soap, so you can choose the soap that suits you best.
