Using this soap dispenser is easy. First, if you're using the Multi - Feed system, make sure you've bought the “6 - SOAP - MFT” Soap Multi - Feed Tank separately and filled it up. The dispenser is designed to work with liquid soap that has a viscosity between 100 cps and 5000 cps. Just wave your hand in front of the touch - free dual sensors, and the soap will dispense. The indicator light at the base of the spout will tell you if it has power, if it's activated, and when the soap is running low. You can choose to power it with a Battery pack (4xAA alkaline) or an A/C Adapter. When it comes to maintenance, keep the dispenser clean with a soft cloth. The vandal - resistant construction means it's built to last, but still handle it with care. Also, remember it's a non - returnable item. Make sure to follow the ADA guidelines when installing it as it's compliant with them, and since it has UL and CE certified electrical components, it's safe to use.
