Using this soap dispenser is easy. First, make sure you've purchased the 6 - SOAP - MFT Soap Multi - Feed Tank if you're using the Multi - Feed system. Then, choose your power supply, either the battery pack or the A/C adapter. Once it's powered on, the indicator light at the base of the spout will show you its status. When you place your hand under the dispenser, the touch - free dual sensors will activate and dispense soap. Remember, it only works with liquid soap with a viscosity between 100 cps and 5000 cps. For maintenance, check the soap level regularly using the indicator light and refill the tank when it's low. Keep the dispenser clean by wiping it with a soft, damp cloth. Since it has a vandal - resistant construction, it's built to last, but avoid any rough handling. Also, ensure it complies with ADA guidelines when installing it in public areas.
