Using this soap dispenser is easy. First, make sure you have the right power supply. You can either use a battery pack with 4 AA alkaline batteries or an A/C adapter. If you're using the Multi - Feed system, buy the “6 - SOAP - MFT” Soap Multi - Feed Tank separately and connect it. Just wave your hand in front of the dispenser, and the touch - free dual sensors will activate to dispense soap. There's an indicator light at the base of the spout. A light will show if it's powered on, when it's activated, and when the soap is low. As for maintenance, keep the dispenser clean by wiping it with a soft cloth regularly. Check the anti - rotational gasket/washer from time to time to make sure it's in good condition. Also, remember this is a non - returnable item. And make sure to use non - proprietary bulk foam soap for best results.
