Using this soap dispenser is easy. First, open the top - fill opening and pour in your liquid soap. Then, insert 6 D cell batteries into the designated battery compartment. Once set up, place it on the countertop. When you need soap, simply hold your hand under the 2.25 - inch spout, and the dispenser will release soap. Note that you'll need to buy the Top Fill Multi - Feed Kit separately if you want that feature. For maintenance, regularly clean the spout to prevent clogging. And when the batteries run out, replace them promptly to keep the dispenser working well.
