Using your Bradley Verge Soap Dispenser is a breeze. 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 preferred power supply, either the 4xAA alkaline battery pack or the A/C Adapter. Once it's powered on, the indicator light at the base of the spout will show the power status. Wave your hand in front of the dispenser, and the touch - free dual sensors will activate to dispense the foam soap. Remember, this dispenser works best with non - proprietary bulk foam soap. When the indicator light shows low soap, it's time to refill the tank. For maintenance, keep the dispenser clean by wiping it with a soft cloth regularly. Check the anti - rotational gasket/washer periodically to ensure it's in good condition. Also, since it's a non - returnable item, make sure it meets your needs before purchasing. And always follow the ADA guidelines when installing it to ensure proper usage for everyone.
