Using this soap dispenser is easy. First, make sure you've purchased the “6 - SOAP - MFT” Soap Multi - Feed Tank separately if you're using the Multi - Feed system. Fill the tank with liquid soap within the viscosity range of 100 cps to 5000 cps. Choose your power supply, either a Battery pack (4xAA alkaline) or an A/C Adapter. Place your hand under the spout, and the touch - free dual sensor will dispense soap, thanks to its design that reduces false activations. The indicator light at the base of the spout will tell you when it's powered, when it activates, and when the soap is running low. As for maintenance, check the soap level regularly and refill as needed. The dispenser has a vandal - resistant construction, but still handle it with care. Keep it clean by wiping it with a soft cloth. It's important to note that this is a non - returnable item, so make sure it meets your needs before purchasing. And remember, it complies with ADA guidelines, ensuring it's accessible for everyone.
