Using this hand dryer is easy. Just place your hands in the 6 - inch deep drying alcove. In about 17 seconds, your hands will be dry. For safety, make sure it's properly connected to a 115V AC power source. Keep the ceramic water - absorbent surface clean to help it catch and evaporate water effectively. Avoid using abrasive cleaners on the matte black powder - coated finish as it may damage the surface. Regularly check the dryer for any signs of wear or malfunction. If you notice anything unusual, stop using it and contact a professional for maintenance.
