[. . . ] Heating the air simply maintains the same humidity level suspended in the air in the form of water vapour. As soon as the temperature decreases again, this water vapour will start to condense. On the other hand, heating combined with dehumidification (such as in the combined operation of this dehumidifier) is very useful. In fact, the heating function transforms the moisture into water vapour that can be collected by the dehumidifier in an extremely rapid and effective manner. [. . . ] 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.

Meaning of the codes that may be shown on the display: 1. Indicates that tank is not fitted, is full or is positioned incorrectly. 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.

[. . . ] If your appliance is not fitted with a plug, please follow the instructions provided below: WARNING - THIS APPLIANCE MUST BE EARTHED IMPORTANT The wires in the mains lead are coloured in accordance with the following code: E Green and yellow: Blue: Brown: Earth Neutral Live L N As the colours of the wires in the mains lead may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows: The green and yellow wire must be connected to the terminal in the plug marked with the letter E or the earth symbol or coloured green or green and yellow. The blue wire must be connected to the terminal marked with the letter N or coloured black. The brown wire must be connected to the terminal marked with the letter L or coloured red. 25 ENGLISH Always unplug the appliance from the power socket before performing any cleaning or maintenance operations. For safety reasons, never wash the dehumidifier using a jet of water. 5748011200DE350E/GB 21-01-2004 10:49 Pagina 26 Tr o u b l e s h o o t i n g Check the following points before calling your local authorised Service Centre.
