Using the Bradley hand dryer is easy. Just place your hands under the dryer, and the automatic infrared sensors will detect them and start the drying process. It will dry your hands in about 38 seconds. When installing, make sure to use the four 5/16 - inch holes on the base to mount it on the wall surface. Since it's not ADA compliant, be aware of its usage limitations. As for maintenance, it's quite hassle - free. The motor has a safety thermostat and self - resetting thermal cut - off, which helps protect the dryer from overheating. However, if you notice any unusual noises or performance issues, it's best to contact a professional for inspection. Also, keep the air outlet grill clean to ensure good airflow.
