Using this 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. If you opt for the Single Fill System, fill the dispenser at the spout. The touch - free activation means you just wave your hand under the spout, and the soap will dispense. For power, you can use a battery pack (4xAA alkaline) or an A/C Adapter. The indicator light at the base of the spout will let you know when there's power, when the dispenser is activated, and when the soap is running low. As for maintenance, check the soap level regularly and refill as needed. The dispenser has a vandal - resistant construction, but try to keep it away from rough handling. Also, follow the ADA guidelines for proper placement. The electrical components are certified, but if you have any issues, it's best to contact a professional.
