Using this soap dispenser is easy. First, choose your power supply, either the battery pack or the A/C adapter. Then, if you're using the Multi - Feed system, make sure to buy the “6 - SOAP - MFT” Soap Multi - Feed Tank separately. When you put your hand under the spout, the touch - free dual sensors will detect it and dispense soap. Keep an eye on the indicator light at the base of the spout. It will show you if there's power, when it's activated, and when the soap is running low. For maintenance, clean the dispenser regularly with a soft cloth. Avoid using harsh chemicals as they might damage the Brushed Nickel finish. Also, make sure to use liquid soap within the 100 cps to 5000 cps viscosity range. This dispenser is vandal - resistant, but still, try to avoid any rough handling. And remember, it's a non - returnable item, so choose carefully before purchasing.
