Nonetheless, the capacity of the air to hold water vapour is quite limited, and depends on the temperature: the higher the temperature, the more water can be held in the air. Absolute humidity (AH) indicates the quantity of water vapour contained in 1 kg of air, and is expressed in grams. Relative humidity (RH) is the ratio, in percentage terms, between the quantity of moisture contained in 1 kg of air and the maximum quantity that the air can hold at such conditions. [. . . ] 1 B) Continuous external draining If the appliance is to be operated for long periods but you are unable to empty the tank, it is recommended to use the continuous drain facility. 1) Remove the rubber bung from the spout. 2) Drill the inside of the drain spout using a narrow drill bit. To do this, open the door, remove the tank, pass the drain hose supplied through the opening between the door, slightly inclined, and the bottom of the appliance, then reposition the tank and insert the hose on the tank spout (Fig. 5) Make sure that the hose is not higher than the spout, otherwise water will remain in the tank; also check that the hose is not choked. You will need it to plug the hose or close the spout if you revert to draining into the tank. 3 19 ENGLISH tion the appliance in the room to be dehumidified: A free space of at least 50 cm must be left to the sides of the humidifier, so as not to block the circulation of air. The condensate can be drained in one of the following ways: Posi 5748011200DE350E/GB 21-01-2004 10:49 Pagina 20 Description of the controls/Indicator lights Temperature indicator light Hygrometer/ thermostat button Humidity percentage indicator light Display Timer ON indicator light ON/OFF button Decrease humidity/temperature/ hours button Max. power indicator light Power level button Increase humidity/temperature/ hours button Dehumidifying indicator light Heating indicator light MODE button Turbo Power button Turbo power indicator light Timer button "ON/OFF" "MODE" "TURBO 20 button Used to start the appliance. button Used to select the "dehumidification" function, the "heating" function or the "combi" function (dehumidification + heating).

Increase/decrease Di splay humidity/temperature/hours In dehumidification mode, these buttons are used to adjust the desired humidity level, with 5% steps, and in heating mode to set the desired temperature; they are also used to set the timer. Meaning of the codes that may be shown on the display: 1. "dF" Indicates that the appliance is in Standby mode. Indicates that the appliance is operating in TURBO POWER mode. Indicates that tank is not fitted, is full or is positioned incorrectly. Indicates that the appliance is operating at low temperature. In this mode, ventilation cycles are alternated with dehumidification cycles to avoid the formation of frost. For use in particularly cold environments, heating is recom mended, so as to raise the ambient temperature even by just a few degrees. This allows the dehumidifier to operate in conditions that improve its perfor mance and accelerate the dehumidification process. Indicates that there may be fault with the probes, or that the ambient humidity is low. 5.
