Using this product is a breeze. First, install it on the surface using the provided skirt. For the paper towel part, load the 8' wide and up to 8' diameter rolls into the module. When you need a paper towel, just give a gentle pull, and the touch - free mechanism will dispense 12' of towel for you. The automatic transfer feature will take care of the stub roll. As for the waste receptacle, simply unlock it when it's full, empty it, and then lock it back into the cabinet. Maintenance is simple too. Wipe the satin - finish stainless steel body regularly with a soft cloth to keep it looking good. Avoid using abrasive cleaners as they might damage the finish. If you want to change the dispenser module, it can be easily done without having to replace the wall cabinets. Refer to the accessories and related products for additional options that you can use with this unit.
