Air always contains a certain amount of water in the form of vapour. This is commonly
known as humidity. 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
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. Below these levels tha air can feel too dry an may cause skin complaints and even
static electric shocks
With temperatures lower than 5°C, you are recommended to heat the room even minimally.
With heating, the condensation formed by the water vapour on windows and other cold sur-
faces evaporates into the air to be collected by the dehumidifier.
Air leaving the dehumidifier is usually about 1°C warmer than room temperature.
Brief notes on humidity
At the end of its working life, the product must not be disposed of as urban waste.
It must be taken to a special local authority differentiated waste collection centre or to a dea-
ler providing this service.
Disposing of a household appliance separately avoids possible negative consequences for
the environment and health deriving from inappropriate disposal and enables the consti-
tuent materials to be recovered to obtain significant savings in energy and resources.As a
reminder of the need to dispose of household appliances separately, the product is marked
with a crossed-out wheeled dustbin.

Electrical connections
Before using for the first time, the dehumidifier should be stood upright for 24 hours.
Failure to respect this safety rule absolves the manufacturer from all liability. This appliance is manu-
factured in compliance with ECC standard EN55014 on the suppression of radio interference.
The cable must be replaced by approved service personnel only.
After moving the appliance, wait at least an hour before turning it on again.
Before plugging the appliance into the mains 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 is adequately earthed.

Position the appliance in the room to be dehumidified:
A free space of at least 50 cm must be left at the front and back of the dehumidifier, so as not
to block the air intake or outlet.
Do not place the dehumidifier next to a radiator or other heat source as this will reduce its
For ongoing usage we suggest positioning in a hallway or on a landing. Please remember to
keep internal door ajar to allow circulation.
The water collected (condensate) can be drained in one of the two ways:
A) Draining into the tank
The condensate can be drained directly into the tank (fig.1).
The tank can be easily removed (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) Remove the continuous drain cap (8) and the rubber bung (see figure 2).
2) Fasten the rubber hose to the spout. For models supplied without drain hose, we sugge-
st you purchase a rubber hose around 2m long, with an internal diameter of 13.5 mm.
3) Make sure the end of the hose is no higher than the spout or water could remain in the
tank. Check there are no kinks in the hose (Fig. 3).
N.B.: 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)

How to dehumidify
How to dehumidify
1) Plug the appliance into a mains socket.
2) Make sure the “tank full/tank missing” light is off. If it is on, position the tank correctly or
empty it.
3) Turn the humidistat dial to one of the positions between OFF and CONTINUOUS. The ON light
indicates that the appliance is dehumidifying. With the humidistat turned to "CONTINUOUS",
the appliance is on all the time.
standby light
Tank full/tank missing light
ON light
To easily select the right humidity level, we suggest you operate as follows:
Turn the humidistat dial clockwise as far as it wil go to the continuous position.
Leave the unit on this seting until signs of excess moisture (e.g. condensation on windows)
decreases. This can take several weeks at this point slowly turn the humidistat knob anti-
clockwise until the appliance switches off. The dehumidifier will then keep the humidity at the
selected level automatically.

or placed too high above the drain spout . . . . . . . . . .remove the obstruction
When the cause has been removed, the light goes off and the appliance resumes operation.
ON Dehumidifying light
This comes on when the appliance is dehumidifying. The light stays on only while the applian-
ce is actually dehumidifying. If the humidity in the room is sufficiently low, the light remains off.
Dehumidifying standby/low-temperature operation light
The light comes on to indicate low temperature operation.
When the room temperature is too low, the electronic low temperature operation device is
activated. This device allows the appliance to operate by alternating dehumidification cycles
and fan only cycles. This is to avoid the formation of ice. For frequent use in cold environ-
ments, it is recommended to heat the room at the same time.
This allows the dehumidifier to operate in conditions that ensure better performance and faster

impor tant safeguards
Always unplug the appliance from the power socket before performing any cleaning or main-
tenance operations.
For safety reasons, never wash the dehumidifier using a jet of water.
Cleaning 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.
Cleaning 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, take out the tank and extract the fil-
ter by pulling downwards (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 repo-
sitioning it.
If the appliance is not used for long periods
• After having unplugged the appliance from the power
socket, empty the tank.
• Clean and reposition the filter.
• Cover the appliance with a plastic bag so that dust does
not build up.
