Using your Bobrick B - 359 paper towel dispenser is easy. First, make sure you've prepared the right type of towels, either 350 C - fold or 475 multi - fold ones. To refill, simply swing down the door at the bottom. It's equipped with a full - length stainless steel piano - hinge for smooth operation. When it comes to installation, measure the rough wall opening carefully. It should be 11 1/4' wide, 15 5/8' high, and at least 4' deep. For maintenance, wipe the satin - finish stainless steel surface regularly with a soft cloth to keep it looking new. Avoid using abrasive cleaners as they might damage the finish. Also, check the hinge periodically to ensure it's working properly. If you notice any issues with towel dispensing, make sure the towels are loaded correctly.
