Using the ASI 04684 - 50 dispenser is easy. First, make sure it's properly installed in the rough opening in your restroom. To restock, unlock the door with the key for the tumbler locks. Place the tampons in one slot and the sanitary napkins in the other according to the size requirements. When customers use it, they just insert 50 cents to get a product. For maintenance, regularly wipe the dispenser with a soft cloth to keep the No. 4 satin finish looking good. Check the locks and hinges periodically to ensure they're working properly. If there are any issues, contact the manufacturer for support. Always keep the dispenser stocked to meet the needs of your restroom users.
