movable parts (figure 1). These parts can be washed directly under the
water faucet.

plate and heating plate are prone to accumulate scale. Users should wash
them regularly with detergent, and clean the inside of the water tank and the
water box every week under the following instruction: Place 5 drops of dish
soap on the surface of the atomizing plate and 5 drops of dish soap on the
heater. Pour in approximately 30mL of water. Use a dish brush or sponge to
clean the atomizing plate, heater, and sink until all lime-scale is removed.
