Using the ASI 1000 waste chute is easy. First, find a countertop opening with a 5 - 3/4 - inch diameter in your commercial restroom's sink area. Apply a silicone sealant and securely mount the chute into the opening. Once it's properly sealed, place a waste receptacle right under it. That's it! Your waste chute is ready for use. When using, make sure not to put overly large or hard objects into the chute to avoid blockage. For maintenance, regularly wipe the chute with a soft cloth to keep its No. 4 satin finish looking good. If there's any dirt or stains, you can use a mild cleaning agent. Just be careful not to scratch the stainless - steel surface.
