Using your Gojo TFX Touch-Free Soap Dispenser is easy. First, insert three C-size batteries into the dispenser (batteries not included). Then, open the dispenser and insert the 1,200-ml soap refill. You can easily check the soap level through the clear side panel strip or the extra-large window. To use, simply place your hand under the dispenser, and it will automatically dispense a perfect amount of thick, foamy soap. When it's time to refill, replace the empty cartridge with a new one. Remember to keep the dispenser away from water to prevent damage. If the dispenser stops working, check the batteries. For long - lasting performance, clean the dispenser regularly with a soft, dry cloth.
