Using this Bradley combination unit is super easy. First, install it in a recessed space as per the provided instructions. For loading towels, simply open the door using the key for the tumbler lock. You can choose to load either C - fold or multi - fold paper towels depending on your preference. When the towels are used up, just refill them in the same way. For the waste receptacle, when it's full, open the door and take out the removable stainless steel insert. Empty the waste into a larger trash bin and then put the insert back. As for maintenance, use a mild soap and a soft cloth to clean the stainless steel surfaces regularly. Avoid using abrasive cleaners as they can scratch the finish. Check the hinge and lock periodically to make sure they are working properly. If you notice any issues, contact the Bradley customer service for assistance.
