Using this sanitary product dispenser is easy. First, make sure it's installed correctly according to the mounting type you've chosen. For the coin - operated models, insert 25 cents into the coin mechanism. The door will unlock, and you can take out a napkin or a tampon. If you're using the free - operation Model 4017, just open the door directly. When it comes to maintenance, regularly clean the dispenser with a mild soap and water solution to keep the stainless - steel finish looking good. Check the coin box frequently to empty it and make sure the coin mechanism is working properly. Keep spare replacement collars on hand in case you need to change the mounting style or if the existing collar gets damaged. Always use the separate keys for the coin box and the door as intended to ensure security.
