Using this hand dryer is easy. Just place your hands in the 6 - inch deep drying alcove. The dryer will start working automatically and dry your hands in about 17 seconds. For the best results, keep your hands still inside the alcove. As for maintenance, make sure to regularly clean the ceramic water - absorbent surface. You can use a mild cleaning agent to wipe it down. When it comes to safety, always ensure it's connected to a 115v power source. Don't try to open the dryer yourself, as it may void the 5 - year limited warranty. If you encounter any problems, contact the customer service.
