Using this soap dispenser is easy. First, install the power supply, either the battery pack or the A/C adapter. Then, connect the Multi-Feed Tank if you're using the Multi-Feed system. Wave your hand in front of the sensor, and the dispenser will release foam soap. Remember, for the Multi-Feed system, you need to buy the '6-SOAP-MFT' tank separately. If you choose a Single Fill System, look for a part number with a 'T'. To maintain it, keep the dispenser clean. Wipe it regularly with a soft cloth. Check the indicator light at the spout base. If it shows low soap, refill the tank. Also, make sure the dispenser is installed in a place where it won't be easily damaged as it has a vandal-resistant design.
