Using this product is easy. To use the towel dispenser, simply place the roll paper towel inside and make sure it fits properly. When you need a towel, just wave your hand in front of the sensor, and it will dispense the towel. For the waste receptacle, open the door by unlocking the tumbler lock, and throw your waste inside. When it's full, empty it. As for maintenance, regularly clean the stainless steel surfaces with a mild cleaner to keep the satin finish looking great. Check the sensor of the towel dispenser periodically to ensure it's working correctly. If you're installing it, remember to consult the ADA codes to meet the installation requirements.
