Using this soap dispenser is easy. First, make sure you've purchased the “6-SOAP-MFT” Soap Multi-Feed Tank separately and installed it properly. Then, choose your power supply - either the battery pack with 4xAA alkaline batteries or the A/C Adapter. Once powered on, the indicator light at the base of the spout will show power status. When you place your hand under the spout, the touch-free dual sensor will detect it and dispense the non-proprietary bulk foam soap. Be aware that this is a non-returnable item. For maintenance, regularly check the soap level through the indicator light. If it's low, refill the soap tank. Also, keep the dispenser clean by wiping it with a soft cloth. The vandal-resistant construction helps protect it, but try to avoid any rough handling. And remember, it complies with ADA guidelines for accessibility.
