Using the ASI 0469 is a breeze. The towels are self - feeding, so you don't have to do much until the supply runs out. You can reload the dispenser with a partial load, and it will keep feeding properly. The waste container needs to be emptied manually based on your maintenance schedule. To install, use four No 10 self - tapping screws through the concealed mounting holes provided. Remember, the top of the Rough Wall Opening is 3/4' below the top of the unit. For ADA compliance, install it so the towel dispenser slot is at most 48' above the finished floor. As for maintenance, since it's made of stainless steel, a simple wipe - down with a mild cleaner will keep it looking great. Make sure to keep the key handy for the tumbler locks to prevent unauthorized access. And always check the paper towel supply regularly to ensure a continuous service for your users.
