Using this hand dryer is easy. Just place your hands under the dryer, and it will start automatically due to its smart sensor. The dual air outlets quickly dry your hands. When it comes to maintenance, keep the dryer clean by wiping the stainless - steel cover regularly with a soft cloth. Avoid using abrasive cleaners as they may scratch the surface. For electrical safety, make sure the power supply matches the dryer's specifications (208 - 240 AC, 6.8 - 7.8 Amp, 50/60 Hz, single - phase). If you notice any issues like abnormal noise or reduced drying power, turn off the dryer and consult a professional.
