Using your ASI 0338 automatic soap dispenser is easy. First, make sure it's properly connected to an AC power source. Then, open the top-fill opening and pour in your favorite liquid soap up to the 50.7-ounce capacity. Place it on your vanity mount securely. When you need soap, simply hold your hand under the dispenser, and it will automatically dispense the right amount. For maintenance, clean the exterior regularly with a soft, damp cloth. Avoid using abrasive cleaners as they may scratch the bright stainless finish. If the dispenser isn't working properly, check the power connection and make sure there's enough soap inside. That's all there is to it for a long - lasting and efficient soap - dispensing experience.
