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, just place your hands under the spout, and the touch - free dual sensors will dispense soap. The indicator light at the base of the spout will show you if it's powered, when it activates, and when the soap is running low. When it comes to maintenance, regularly check the soap level and refill as needed. If you notice any issues with the dispenser not working properly, check the power source and make sure the sensors are clean. Keep in mind that this is a non - returnable item, so choose the right fill system for your needs. Also, the dispenser is designed to be vandal - resistant, but still handle it with care to keep it in good condition.
