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. Fill the tank with your preferred non-proprietary bulk foam soap. Then, select your power supply - either install 4 AA alkaline batteries or connect the A/C Adapter. Once it's powered on, the indicator light at the base of the spout will show its status. When you place your hand under the spout, the touch-free dual sensors will detect it and dispense soap. Be aware that this item is non-returnable. For maintenance, regularly check the soap level using the indicator light and refill as needed. Keep the dispenser clean by wiping it with a soft cloth. The vandal-resistant design helps protect it, but avoid any rough handling. Also, ensure it complies with ADA guidelines when installing it.
