Using the ASI 0332-C soap dispenser is easy. Just push the manual - push button to get the liquid out. When it's time to refill, use the included specialized refill key to open the top of the dispenser and add your commercial hand soap, lotion, or detergent. Make sure to install it in an area with a 7/8 - inch diameter cutout in the sink. Be careful not to force the spout too hard, although it can rotate 360 degrees. To maintain it, regularly wipe the stainless - steel parts with a clean cloth to keep it looking good and prevent corrosion. Also, check the soap container for any signs of damage, but since it's made of shatterproof polyurethane, it should be quite durable.
