Using your ASI 0332 soap dispenser is a breeze. Just give the manual - push mechanism a gentle press, and the soap will come out. When it's time to refill, use the specialized key provided to open the top of the dispenser and pour in up to 34 ounces of your preferred commercial - grade liquid soap, lotion, or detergent. For installation, make sure to cut a 7/8 - inch diameter hole in the sink area where you want to mount the dispenser. As for maintenance, wipe the stainless - steel body regularly with a soft, damp cloth to keep it looking shiny. Avoid using abrasive cleaners as they may scratch the surface. Since the container is made of shatterproof polyurethane, it's quite durable, but still handle it with care to prevent any accidental knocks.
