Using this towel dispenser is easy. Just open the lock with the provided key, load your C - fold or multifold towels, and close it up. When someone needs a towel, they can simply pull it out from the dispenser. Here are some things to keep in mind. Make sure to use only the recommended number of C - fold (up to 300) or multifold (up to 400) towels to avoid jams. If you plan to change the mounting to recessed, remove the skirt carefully. For maintenance, clean the dispenser regularly with a mild soap and a soft cloth. Avoid using abrasive cleaners as they can damage the matte black finish. If the lock has any issues, you can contact Bobrick's customer service using the key's matching information to get it fixed.
