Using this hand dryer is easy. Just place your wet hands into the 6 - inch deep drying alcove. The dryer will start working automatically and dry your hands in about 17 seconds. When using, make sure your hands are within the alcove for the best drying result. As for maintenance, keep the ceramic water - absorbent surface clean. You can wipe it gently with a soft cloth regularly. Also, since it's made of stainless steel, avoid using abrasive cleaners that might scratch the surface. And remember, this dryer comes with a 5 - year limited warranty, but make sure to follow the basic usage and maintenance rules to keep it in good condition.
