Using your Bradley touchless soap dispenser is easy. First, if you're using the Multi - Feed system, make sure you've purchased and installed the “6 - SOAP - MFT” Soap Multi - Feed Tank. Power it up using either a 4xAA alkaline battery pack or an A/C Adapter. When you place your hands under the spout, the touch - free dual sensors will detect them and dispense foam soap. Keep an eye on the indicator light at the base of the spout. It will show you when the dispenser is powered, when it's activated, and when the soap is running low. For maintenance, clean the dispenser regularly with a soft, damp cloth. Avoid using abrasive cleaners that could damage the brushed stainless steel finish. Make sure to check the anti - rotational gasket/washer periodically to ensure the vandal - resistant construction stays intact. And remember, this item is non - returnable.
