Using this Gojo Cxi touch-free foam soap dispenser is a breeze. First, make sure it's properly mounted on your countertop. Insert the batteries as per the instructions inside the dispenser. Then, load a GOJO CX 1500 or 2300 mL refill into the dispenser. When you need soap, simply place your hand under the dispenser, and it will automatically dispense the foam. For safety, keep it out of reach of children and avoid getting water inside the battery compartment. To maintain it, wipe the dispenser regularly with a soft, dry cloth to keep the chrome finish shiny. If it stops working, check the batteries and make sure they're inserted correctly. And don't forget, it comes with a three-year guarantee, so you're covered if there are any issues.
