Using the ASI 0468 - F dispenser is easy. Just open the door with the key provided for the tumbler locks. Then, load the sanitary napkins into one slot and the tampons into the other. When someone needs a product, they can simply access it for free. Remember to keep the key in a safe place to prevent unauthorized access. For maintenance, regularly clean the dispenser with a mild soap and water solution. Wipe it dry to avoid rusting, especially since it's made of stainless steel. Check the locks periodically to make sure they're working properly. Also, keep an eye on the product levels and refill when necessary to ensure continuous availability for users.
