Using your Bradley 6 - 3300 RFM - PC Touchless Foam Soap Dispenser is easy. First, make sure you've installed the power supply. You can use either a 4xAA alkaline battery pack or an A/C Adapter. If you're using the Multi - Feed system, you'll need to purchase and connect the “6 - SOAP - MFT” Soap Multi - Feed Tank separately. Just wave your hand under the dispenser, and the touch - free dual sensors will activate to dispense the soap. The indicator light at the base of the spout will show you if the dispenser is powered, when it's activated, and when the soap is running low. Remember, this is a non - returnable item. Also, it's designed to be vandal - resistant, but try to avoid any rough handling. For maintenance, keep the dispenser clean. You can use a soft cloth to wipe the chrome finish. Since it's compatible with non - proprietary bulk foam soap, you can easily refill it with your preferred soap brand. And don't forget, it meets ADA guidelines, so it's suitable for all users.
