Some notions on humidity
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
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.
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:
The wires in the mains lead are coloured in accordance
with the following code:
Green and yellow Earth
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.

lectrical connections
After moving the appliance, wait at least an hour before turning it on again.
Before plugging the appliance into the power socket, check that:
• The mains power supply corresponds to the power supply indicated on the rating plate.
• The power socket and electrical circuit are adequate for the appliance.
• The power socket matches the plug. If this is not the case, have the plug replaced by a qualified
• The power socket must be adequately earthed.
osition the appliance in the room to be dehumidified.
A free space of at least 50 cm must be left at the front of the dehumidifier, so as not to block
the air outlet. For efficient ventilation a space of about 5-10 cm should be left at the back of
the appliance.
The condensate can be drained in one of the following ways:
A) Draining into the tank
The condensate can be drained directly into the tank (fig. 1)
The tank can be easily removed and has a handle making it simple to carry and empty
(fig. 1).
fig. 1
B) Continuous external draining
If the appliance is to be operated for long periods but you are unable to empty the tank regularly,
you are recommended to use the continuous drain facility.
1) Drill the inside of the drain spout using a narrow drill bit. (Fig. 2)
2) Fasten the rubber hose to the spout. For models without drain hoses supplied, we suggest you purchase a rubber hose around 2m long, with an internal diameter of 9.5 mm.
3) Make sure that the hose is not higher than the spout In caso contrario l’acqua resterà
nella tanica; verificare inoltre che il tubo non sia strozzato (Fig. 3). or water could remain
in the tank. Check the hose is not choked (Fig. 3).
Keep the rubber bung. You will need it to plug the hose or close the spout if you
revert to draining into the tank. (see point A).

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.
leaning the cabinet
• Clean the appliance using a damp cloth then dry with a dry cloth.
• Never use petrol, alcohol or solvents to clean the appliance.
• Never spray liquid insecticide or similar products as they may deform the plastic.
leaning the air filter
If the filter is dirty, air circulation is compromised and the efficiency of the dehumidifying and
air purifying functions decreases. It is therefore good practice to clean the filter at regular intervals. The frequency depends on the duration and conditions of operation. If the unit is used
constantly or systematically, you are recommended to clean the filter once a week.
• To remove the air filter, extract by pulling (fig. 4).
• Use a vacuum cleaner to remove dust accumulations from
the filter. If the filter is very dirty, wash in warm water and rinse
several times.
The temperature of the water must not exceed 40°C. After
washing the filter, allow it to dry completely before repositioning it.
f the appliance is not used for long periods
• Unplug from the mains socket and empty the tank.
• Clean and reposition the filter.
• Cover the appliance with a plastic bag so that dust does
not build up.
