Using this waste receptacle is easy. First, make sure you have the right rough opening size in the wall. Install the unit as per the instructions, and it will stick out about 8 inches from the wall. Put the reusable vinyl liners on the plastic hooks inside the receptacle to keep it clean. When it's time to empty the waste, use the key to open the tumbler lock and remove the receptacle. For maintenance, regularly wipe down the shiny satin - finished surfaces with a soft cloth. Avoid using abrasive cleaners that could scratch the stainless - steel. If the lock seems to be having issues, check for any debris and make sure to keep the key in a safe place.
