Using your Bradley hand dryer is easy. Just place your hands under the dryer, and the automatic infrared sensor will detect them and start the drying process. The dryer will automatically shut off after 60 seconds, so you don't have to worry about it running continuously. When it comes to voltage, make sure to connect it to the appropriate power supply - it can work with 110 - 120V, 208V, or 220 - 240V. For maintenance, keep the dryer clean by wiping it regularly with a soft, dry cloth. Avoid using abrasive cleaners as they might damage the white epoxy finish. Check the thermal cut - off periodically to ensure it's working properly. If you notice any unusual noises or if the drying time becomes longer than the normal 12 - 15 seconds, it might be time to have it checked by a professional.
