The operation will be described with reference to the flowchart of FIG. 6. If the operation switch 38 is pressed, the water level in the drain tank 18 is determined by the water level detecting means 26 in S1. If the tank is full, the operation proceeds to S2. If there is little water, proceed to S3. In S2, the red LED 44 of the color display 41 blinks red, which is an advanced color having a visual advancing action, to urge the user to drain the water of the tank 18 and to display the liquid crystal display 39 of the operation unit 35 with " The display of "full" is displayed, and the operation of the compressor 24, the fan motor 12, and the like is not performed.

In S3, it is determined whether or not the previous operation was an automatic operation. If the operation is an automatic operation, the process proceeds to S4, and if not, the process jumps to S6.
