Using this soap dispenser is easy. First, make sure you've purchased the “6 - SOAP - MFT” Soap Multi - Feed Tank separately if you're using the Multi - Feed system. Install the dispenser on your counter and choose your power source, either the battery pack (4xAA alkaline) or the A/C Adapter. Once it's set up, just wave your hand in front of the sensors, and the soap will dispense. The indicator light at the base of the spout will let you know if there's power, when it activates, and when the soap is running low. Remember, this is a non - returnable item. For maintenance, keep the dispenser clean with a soft cloth. Check the anti - rotational gasket/washer regularly to ensure it's in good condition. Since it meets ADA guidelines, it's suitable for a wide range of users. Also, always use non - proprietary bulk foam soap to keep it working properly.
