ACID 30 min 140°F / 60°C If there is no water left in my water tank, for how many hours will the water in the base last? • An exact answer cannot be given for this as there are many factors that depend on how long the water will last for. It all depends on the size of the room, if it is very dry, among other things to know how quickly water will evaporate into the air. If you notice that there is no water left in the water tank, it is always a good idea to refill the tank to have extra water available. Red LED light is illuminated – what does it mean? • The red LED light on the appliance shows you when the unit should be refilled with water. If the water level falls below the minimum level, the appliance automatically switches off. The red LED appears on the display. When water is added, the red LED changes to green and the appliance continues operating. Please note: When lifting the upper part off the housing, the appliance also switches off. In this case, the red LED will also appear on the display. Only when the upper part is replaced on the base does the red LED (E) disappear and the appliance resumes operation. I fill the water tank, and when I place it back on the unit all of the water goes into the base. Why is that? • Water is needed in the base of the unit for the removal of particles from the air, and for the humidification of the air. The first time the tank is filled up and placed on the unit, all of the water will go into the base of the unit. The water tank acts as a reserve, and may be filled up a second time to have extra water available. Is it ok to put my humidifying discs in the dishwasher? • The manufacturer of this appliance does NOT recommend it. The discs can only be placed in a dishwasher where the temperature is no greater than 131°F / 55 .C. If the temperature is any hotter than this, the discs will melt. Place the plates in a sink filled with warm water and white vinegar or EZCal and either let them soak or spin the plates in this solution. Or, add white vinegar or EZCal to the water in the base of the unit and let the unit run for an hour to clean the plates. It is good to have calcium deposits built up on the plates as it will capture more particles from the air and add more moisture to the air. For troubleshooting, see chapter «Troubleshooting». Humidity level is not changing or does not reach the desired humidity level • If the water tank needs refilling more than once per day, the unit is working properly and the climatic condition in the room has an influence on the humidity. Reasons for low humidity level: • air circulation is very high (air is fully exchanged several times pe...
