The water tank is large enough that you do not have to empty it every five minutes, but only from time to time to see if the red light. (In the first device that we had, it was difficult, the water tank rauszuholen, but when I wrote Comedes of these difficulties, they have since unit replaced immediately at their own expense.)
At first I was a little irritated that the instruction manual is so lean. Now I know: this machine needs no instruction manual!
Should to ensure the longevity of the device to be necessarily follow the recommended "rest periods", is to say, put the device until 30 minutes after installation in operation and always rest at least 30 minutes or turned: Important note. (If the device is left to its own, it does already)
