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, choose your power supply, either the battery pack or the A/C adapter, and connect it. When you place your hand under the spout, the touch - free dual sensors will detect it and dispense soap. The indicator light at the base of the spout will show you the power status, when it's activated, and if the soap is running low. As for maintenance, regularly check the soap level and refill when needed. Clean the exterior of the dispenser with a soft, damp cloth. Since it has a vandal - resistant construction, it can withstand some rough handling, but try to avoid hitting or dropping it. Also, keep in mind that it's a non - returnable item. This dispenser is compatible with liquid soap in the 100 cps to 5000 cps viscosity range, so make sure to use the right type of soap.
