Using this soap dispenser is easy. First, if you're using the Multi - Feed system, make sure you've bought the “6 - SOAP - MFT” Soap Multi - Feed Tank and installed it properly. Place your hand under the spout, and the touch - free dual sensors will activate to dispense soap. You can choose to power it with either a Battery pack (4xAA alkaline) or an A/C Adapter. The indicator light at the base of the spout will tell you if it's powered, when it's dispensing soap, and when the soap is running low. Remember, this is a non - returnable item. 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. Since it complies with ADA guidelines, use it in accordance with those regulations. And because the electrical components are UL and CE certified, make sure to follow basic electrical safety rules.
