Using this vendor is simple. Just insert a quarter (U.S. or Canadian) into the single coin slot. Then, press the button to select your desired product, whether it's a tampon or a napkin. If you change your mind, press the coin return button and the coin will drop into the product tray. When the product runs out, the coin slot will be automatically blocked. For loading products, you don't need to deal with any weights. Just open the door using the key and place up to 30 tampons or 20 napkins inside. Keep the key for the coin box in a safe place for management access. To convert the coin value, it's easy to switch from 25₵ to 50₵ or use tokens. For cleaning, use a mild cleaner on the Type 304 stainless steel matte black finish. Don't use abrasive materials that could scratch the surface. Order the free vend conversion kit (part No. 3706-250) for schools or the token vend conversion kit (part No. 3706-166) when needed.
