Using your Verge Deck-Mounted Touchless Infrared Sensor Foam Soap Dispenser is a breeze. First, make sure you've purchased and installed the “6-SOAP-MFT” Soap Multi-Feed Tank if you're using the Multi-Feed system. If you've chosen the Single Fill System, ensure you have the right part number with a “T”. To operate, simply place your hand under the spout, and the touch-free dual sensors will detect it and dispense soap. The indicator light at the base of the spout will tell you if the dispenser is powered, when it's activated, and when the soap is running low. When it comes to power, you can use either a Battery pack (4xAA alkaline) or an A/C Adapter. Just pick the option that suits your needs. For maintenance, keep the dispenser clean by wiping it regularly with a soft, damp cloth. Check the anti-rotational gasket/washer periodically to make sure it's in good condition. Since it's a non-returnable item, handle it with care. Also, remember to use non-proprietary bulk foam soap for the best results. This dispenser complies with ADA guidelines, so use it with confidence knowing it meets high standards.
