Using this paper towel dispenser and waste receptacle is easy. First, install it by making a rough opening of 12 - 3/4 inches wide, 26 - 1/2 inches high, and 4 inches deep. Then, load 350 C - Fold or 475 Multi - Fold paper towels into the dispenser at the top. When you need a paper towel, simply pull it out from the hemmed opening. For waste disposal, open the waste receptacle at the bottom using the rolled finger hole. Remember to keep the tumbler lock key in a safe place to prevent unauthorized access. To maintain this unit, regularly clean the stainless - steel surface with a mild cleaner to keep its satin finish. Check the paper towel supply and empty the waste receptacle when it's full to ensure smooth operation.
