Using this soap dispenser is easy. First, choose your power source, either the battery pack with 4 AA alkaline batteries or the A/C adapter. If you're using the Multi - Feed system, make sure to buy the “6 - SOAP - MFT” Soap Multi - Feed Tank separately. Once it's set up, just wave your hand in front of the sensors, and the soap will dispense. You'll see an indicator light at the base of the spout. A lit light shows power, activation, and when the soap is running low. When it comes to maintenance, keep it clean with a soft, damp cloth. Don't use abrasive cleaners as they can damage the Brushed Nickel finish. Also, make sure to replace the soap in the tank regularly to keep it working well. And remember, this is a non - returnable item, so choose the fill system (Multi - Feed or Single Fill) that suits your needs. It's designed to be vandal - resistant, but still handle it with care to ensure long - term use.
