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. Fill the tank with liquid soap that has a viscosity between 100 cps and 5000 cps. Select your preferred power supply, either the battery pack or the A/C adapter. When you place 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 tell you if there's power, when the dispenser is activated, and when the soap is running low. For maintenance, clean the dispenser regularly with a soft cloth to keep its polished chrome finish looking great. Since it has a vandal - resistant construction, it's durable, but still handle it with care. And remember, this item is non - returnable.
