Using this soap dispenser is easy. First, open the EZFill vanity - mounted top - fill port and pour your favorite liquid soap into the multi - feed tank. Then, place batteries in the sensor housing. Once it's all set up, just wave your hand in front of the sensor, and the soap will come out. Remember, the batteries are not included. As for maintenance, regularly wipe the dispenser with a soft, damp cloth to keep the high - gloss finish looking great. Check the LED on the front to know when the batteries need to be replaced.
