Using this soap dispenser is easy. First, make sure you've purchased and installed the “6 - SOAP - MFT” Soap Multi - Feed Tank if you're using the Multi - Feed system. Then, select your power supply, either the battery pack or the A/C adapter. Once it's powered on, simply wave your hand in front of the sensor, and the dispenser will release foam soap. Remember, this item is non - returnable. Check the indicator light at the base of the spout regularly. A change in its status can tell you about power, activation, and low soap levels. For maintenance, clean the exterior of the dispenser with a soft, damp cloth. Avoid using abrasive cleaners as they can damage the Brushed Brass finish. Since it has a vandal - resistant design, it's built to last, but still handle it with care to keep it in good condition. And don't forget, it meets ADA guidelines, so it's suitable for all users.
