Using this hand dryer is easy. Just place your hands in the 6 - inch deep drying alcove, and it will dry them in about 17 seconds. It's quiet, so you won't be bothered by loud noise. Make sure to use it with a 115V AC power supply. For maintenance, keep the ceramic water - absorbent surface clean. Wipe it regularly to ensure it can capture and evaporate water properly. Don't use abrasive cleaners on the matte black powder - coated finish as it may damage the surface. Also, check the dryer periodically to make sure it's running smoothly and the power rating remains stable.
