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. Then, select your preferred power supply, either the battery pack or the A/C adapter. Once it's powered on, the indicator light at the base of the spout will show the status. Just wave your hand in front of the dispenser, and the touch - free dual sensors will activate to dispense the liquid soap. Remember, this dispenser only works with liquid soap having a viscosity between 100 cps and 5000 cps. For maintenance, regularly check the soap level through the indicator light. When it's low, refill the soap tank. Keep the dispenser clean by wiping it with a soft, damp cloth. Avoid using abrasive cleaners as they may damage the Brushed Bronze finish. Also, make sure to follow ADA guidelines when installing it in public spaces.
