Using this soap dispenser is easy. First, make sure you've got the right power supply. You can use either a 4xAA alkaline battery pack or an A/C adapter. If you're using the Multi - Feed system, install the “6 - SOAP - MFT” Soap Multi - Feed Tank separately. Once it's all set up, just wave your hand in front of the dispenser, and the touch - free dual sensors will activate to dispense the foam soap. Keep an eye on the indicator light at the base of the spout. It'll tell you when the dispenser is powered on, when it's activated, and when the soap is running low. As for maintenance, clean the dispenser regularly with a soft, damp cloth to keep it looking its best. Avoid using abrasive cleaners that could damage the Brushed Black Stainless finish. Also, make sure the anti - rotational gasket/washer stays in place to keep the dispenser secure. Remember, this is a non - returnable item, so handle it with care. And if you ever want a Single Fill System instead, look for a part number with a “T”.
