If you're having trouble with your wall unit dispensing hand sanitizer, the refill bag may be plugged or not properly clipped into the unit. Please use the button on the underside of your unit to open up the dispenser and remove the refill bag. Hold the bag upright so the sanitizer fills the pump and press down on the button several times to free any blockage. Once the pump is clear and operating, place it back in the unit and make sure the pump button is clipped securely to the unit. It should now dispense normally.
