Using this dispenser is easy. First, unlock the door with the provided key and swing it open. Then, fill the toilet seat-cover dispenser with up to 250 seat covers and each tissue dispenser with a standard core tissue roll. It's recommended to keep one full tissue roll wrapped until the other is used up to avoid waste. When installing, make sure to create a framed rough wall opening with the correct dimensions and follow the guidelines to avoid pipes and vents. For maintenance, simply wipe the stainless-steel surfaces with a mild cleaner. If the spindles need to be removed, do so when the door is open. Keep the key in a safe place to prevent unauthorized access.
