Using this soap dispenser is easy. First, make sure you've got the right power supply - you can use either a battery pack with 4 AA alkaline batteries or an A/C adapter. If you're using the Multi-Feed system, remember to buy the “6-SOAP-MFT” Soap Multi-Feed Tank separately. When your hands are near the dispenser, the touch-free dual sensors will detect them and dispense soap. To keep it in good shape, regularly check the indicator light at the base of the spout. If it shows low soap, refill the tank. Clean the dispenser with a soft cloth regularly to maintain its polished chrome finish. Also, be aware that this is a non-returnable item. And because it has a vandal-resistant construction, it should last a long time, but try to avoid any rough handling. It meets ADA guidelines, so it's suitable for a wide range of users.
