Using this Gojo TFX soap dispenser is easy. First, insert three C-size batteries into the battery compartment. Then, open the dispenser and insert the 1200-ml soap refill. Mount it on the wall using the appropriate hardware. When you place your hand under the dispenser, it will automatically dispense the perfect amount of foam soap. Remember, the batteries are not included, so you'll need to get them separately. Also, keep an eye on the extra-large window. When it shows that the soap is running low, it's time to refill. To maintain it, clean the exterior with a soft, damp cloth regularly. Avoid using harsh chemicals as they may damage the plastic material.
