Using your Verge Linea Series soap dispenser is easy. First, make sure you've purchased and installed the “6 - SOAP - MFT” Soap Multi - Feed Tank if you're using the Multi - Feed system. Power it up using either the 4xAA alkaline battery pack or the A/C Adapter. When your hands are near the dispenser, the touch - free dual sensors will activate and dispense foam soap. Keep an eye on the indicator light at the base of the spout. It'll tell you if there's power, when the dispenser is activated, and when the soap is running low. To maintain your dispenser, clean it regularly with a soft cloth. Make sure to use only non - proprietary bulk foam soap to keep it working well. And remember, this item is non - returnable, so handle it with care.
