SOME NOTIONS ON
HUMIDITY
Air 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 very low temperatures,
you are recommended to heat the room even
minimally.
This considerably increases the dehumidifying
power of the appliance.
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.

Before plugging the appliance into the mains
socket, check that:
• The mains power supply corresponds to the
working voltage indicated on the rating plate.

Important information for correct dispo-
sal of the product in accordance with EC
Directive 2002/96/EC.
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 dealer providing this servi-
ce.
Disposing of a household appliance separately avoids
possible negative consequences for the environment
and health deriving from inappropriate disposal and
enables the constituent materials to be recovered to
obtain significant savings in energy and resources.As a
reminder of the need to dispose of household applian-
ces separately, the product is marked with a crossed-out
wheeled dustbin.

INSTALLATION
Position 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. 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 by turning
it anticlockwise then remove the rubber bung
from the spout (fig. 2).
2) Fasten the rubber hose to the spout.
3) Make sure the end of the hose is no higher
than the spout or water could remain in the
tank. Make sure there are no kinks in the hose
(fig. 3).
Please Note: Keep the rubber bung to close
the spout.
Instructions for fitting the castors
1) Unplug from the mains socket and empty the
tank (if full).
2) Remove the rubber caps from the bottom of
the appliance by pulling forcefully or using
pliers (see figure 4/1).
3) Fit the castors by inserting the pins into the
holes. (see figure 4/2)
Please Note: While fitting the castors, do
not tilt the appliance at an angle of more than 45°.
After fitting the castors, wait for at least an hour
before using the dehumidifier again.

HOW TO DEHUMIDIFY
Dehumidifying standby/freeze
protection light
Humidistat dial
Tank full/tank
absent light
How to dehumidify
• Plug the appliance into a mains socket.
• Make sure the "tank full/tank missing" light is
off. If it is on, position the tank correctly.
• The dehumidifying standby light comes on
during the first three minutes (safety device),
then the appliance starts dehumidifying.
• The humidistat dial is used to adjust the
humidity level as desired (MIN/MED/MAX and
intermediate levels).
When the dial is on MIN, the dehumidifier
removes only a small amount of humidity
from the room. On MAX, it removes a large
amount of humidity.
To dehumidify, adjust the humidistat to one of
the positions available.
Dry mode (drying washing)
To remove a large amount of moisture (for
example when drying washing), you are
recommended to operate the appliance at
maximum power by turning the humidistat dial to
DRY.
In this mode, the dehumidifier operates
continuously, irrespective of the level of humidity
in the room.

INDICATOR LIGHTS
Tank control system light
This dehumidifier has a special device to control
correct operation.
A red indicator light on the control panel comes
on to warn the user when:
1. the tank is full: empty the tank
2. the tank is missing: reposition the tank
3. the tank is incorrectly positioned: position the
tank correctly
4. with continuous drain:
the hose is blocked or sloping upwards (water
is still draining into the tank)
remove the obstruction
When the cause has been removed, the light goes
off and the appliance resumes operation.
Dehumidifying standby/low-tem-
perature operation light
The light comes on:
1) To indicate the appliance is in standby for
about three minutes before start-up. This
device protects the compressor from starting
and stopping too often.
2) To indicate low temperature operation. When
the temperature in the room is too low, the
low temperature operation electronic device
trips.This operates the appliance with
alternate cycles of dehumidifying and fan only
to avoid the formation of ice.
For frequent use in particularly cold rooms,
you are recommended to raise room
temperature, even if only slightly.
This ensures that the dehumidifier is
operating under suitable conditions,
improving its performance and accelerating
dehumidification.

CLEANING AND
MAINTENANCE
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.
Cleaning the cabinet
• Clean the appliance using a damp cloth then
dry with a dry cloth.
• Do not use petrol, alcohol or solvents to clean
the appliance.
• Do not spray liquid insecticide or similar
products as they may deform the plastic.
Cleaning the silver ion 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.
• Remove the air filter by pulling sideways (Fig.
5).
• Use a vacuum cleaner to remove dust accu-
mulations from the filter.
If the filter is very dirty, rinse well in warm
water.
The temperature of the water must not exceed
40°C.
After washing the filter, allow it to dry com-
pletely before repositioning it.
The silver ion filter not just retains dust
particles, but also has an efficient antibacterial
action. It also greatly reduces concentrations
of irritants such as pollen and spores.
The filter is treated with small particles of
silver (on the scale of millionths of a
millimetre) which are able to block the
multiplication of and destroy any bacteria or
spores coming into contact with them.
If the appliance is not used for long
periods
• After unplugging the appliance from the
power socket, empty the tank.
• Clean and reposition the filter.
• Cover the appliance with a plastic bag to
protect it from dust.

in the room (pots of boiling
water, etc.).
The humidy set point is too
high.
Clean the filter.
In certain conditions, it is nor-
mal for the appliance not to
dehumidify (in certain cases,
it is recommended to heat the
environment).
Decrease the humidity set
point.
