Using this soap dispenser is easy. First, make sure you've installed the power supply. You can choose either a 4xAA alkaline battery pack or an A/C adapter. If you're using the Multi - Feed system, you'll need to buy the “6 - SOAP - MFT” Soap Multi - Feed Tank separately and fill it up. When your hands approach the dispenser, the touch - free dual sensors will activate and dispense the foam soap. The indicator light at the base of the spout will show you if the dispenser is powered, when it's activated, and when the soap is running low. Here are some important notes. This is a non - returnable item, so choose carefully. If you want a Single Fill System, look for a part number with a “T”. For maintenance, clean the exterior of the dispenser regularly with a soft, damp cloth. Check the anti - rotational gasket/washer occasionally to ensure it's in good condition. Also, since it complies with ADA guidelines, use it according to those standards to make sure everyone can access it easily.
