Using your Bradley 250-15 paper towel dispenser is a breeze. First, make sure to choose either C-fold or multi-fold paper towels as they are the compatible types for this unit. When it's time to refill, since the cabinet is hinged at the bottom, you can easily open it up and insert the towels. There's a towel level indicator on the front, so you'll always know when it's getting low. For installation, before you start, double-check all the rough - in dimensions. You'll need to use mounting screws (which are not included) and secure the dispenser to the wall at the provided holes. You can also get a mounting kit (#899 - 027) from Bradley if needed. Just visit their website bradleycorp.com for more information. And don't forget to provide in - wall backing at the mounting screw locations. As for maintenance, the stainless - steel construction is durable, but you can wipe it down regularly with a mild cleaner to keep the satin finish looking great. Also, check the tumbler lock occasionally to make sure it's working properly and that the key fits smoothly.
