Using this soap dispenser is easy. First, make sure you've got the right power supply - you can use a 4xAA alkaline battery pack or an A/C adapter. Then, 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 infrared sensor and the soap will dispense. When the indicator light at the base of the spout shows low soap, it's time to refill. Remember, this is a non - returnable item. To keep it in good condition, clean the dispenser regularly with a soft, damp cloth. Avoid using abrasive cleaners as they could damage the polished chrome finish. Also, since it has a vandal - resistant construction, it should be quite durable, but try to avoid rough handling. If you ever need to change the power supply, it's a simple process - just follow the instructions for battery replacement or A/C adapter connection.
