A
ir always contains a certain amount of water in the form of vapour. This determines the
level of humidity in an atmosphere.
The capacity of the air to hold water vapour increases with temperature. This is why, in our
homes, as soon as the temperature decreases, the vapour contained in the air condenses, as
is evident on the colder surfaces in the room, such as the windows, walls etc.
The purpose of a dehumidifier is to remove the excess moisture from the air, avoiding the
damage caused by condensation. Experts have established that the optimum environmental
conditions for our well being and for the home are obtained between 40% and 60% relative
humidity.
With temperatures near 0°C, you are recommended to heat the room even minimally. With
heating, the condensation formed by the water vapour on windows and other cold surfaces
evaporates into the air to be collected by the dehumidifier. Air leaving the dehumidifier is
usually about 1°C warmer than room temperature.
ELECTRICAL CONNECTION (U.K. ONLY)
A) If your appliance comes fitted with a plug, it will incorporate a 13 Amp fuse. If it does not fit your socket, the plug
should be cut off from the mains lead, and on appropriate plug fitted, as below. warning: Very carefully dispose of
the cut off plug after removing the fuse: do not insert in a 13 Amp socket elsewhere in the house as this could cause
a shock hazard. With alternative plugs not incorporating a fuse, the circuit must be protected by a 15 Amp fuse. If the
plug is a moulded-on type, the fuse cover must be re-fitted when changing the fuse using a 13 Amp Asta approved
fuse to BS 1362. In the event of losing the fuse cover, the plug must NOT be used until a replacement fuse cover can
be obtained from your nearest electrical dealer. The colour of the correct replacement fuse cover is that as marked on
the base of the plug.
B) If your appliance is not fitted with a plug, please follow the instructins provided below:
WARNING - THIS APPLIANCE MUST BE EARTHED
IMPORTANT
The wires in the mains lead are coloured in accordance
with the following code:

As the colours of the wires in the mains lead may not cor-
respond with the coloured markings identifying the termi-
nals in your plug, proceed as follows:
The green and yellow wire must be connected to the ter-
minal in the plug marked with the letter E or the earth sym-
bol
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.
