Using the Diplomat Series Toilet Tissue Dispenser is a breeze. First, unlock the tumbler lock with the key provided. Then, open the service door at the bottom of the unit. Place two rolls of up to 5 - 1/4 inch core toilet tissue on the non - removable spindle. Close the door and lock it. As you use the first roll of toilet tissue, it will dispense smoothly. When the first roll is used up, a fresh roll will automatically drop down for use. Remember, the spare roll won't be used until the first one is completely gone. For maintenance, wipe the stainless - steel surfaces regularly with a soft, damp cloth to keep the satin finish looking great. Avoid using abrasive cleaners as they can scratch the surface. If the lock or any part seems to be malfunctioning, contact Bradley for assistance.
