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 go for the Single Fill System, look for the right part number. Once the soap is in the tank, select your power option, either the battery pack or the A/C adapter. Place your hand under the spout, and the touch - free dual sensors will activate to dispense foam soap. Keep an eye on the indicator light at the base of the spout. If it shows a low - soap sign, refill the tank. To maintain it, clean the exterior regularly with a soft cloth. Make sure the anti - rotational gasket/washer stays in place to keep it vandal - resistant. Remember, this is a non - returnable item, so double - check your needs before buying.
