Using this paper towel dispenser is easy. Just load the 300 C - fold or 400 multi - fold towels into the dispenser. When someone needs a towel, they can simply pull one out. Remember to keep the key in a safe place as the dispenser has a tumbler lock. For maintenance, clean the satin - finish stainless steel surface regularly with a soft cloth and mild cleaner. If you want to change the mounting from surface - mounted to recessed, you can remove the skirt in the field. Also, check the dispenser periodically to make sure there are enough towels inside.
