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 tempe-
rature 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 dama-
ge caused by condensation.
Experts have established that the optimum envi-
ronmental conditions for our well being and for
the home are obtained between 40% and 60%
relative humidity. Lower relative humidity can be
achieved with higher room temperatures. For
lower room temperatures the achievable relative
humidity will be on the higher side, closer to
60%. Therefore, with lower room 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 surfa-
ces evaporates into the air to be collected by the
dehumidifier.

SAVE THESE
INSTRUCTIONS
THIS PRODUCT IS FOR
HOUSEHOLD ONLY
Appropriate use
The appliance is designed and produced for
domestic use only.
Use this appliance only as described in this
instruction manual.
As with all electrical equipment, the instructions aim
to cover as many eventualities as possible.
However, caution and common sense should be
applied when operating and installing this applian-
ce.
General safeguards
• Do not install the appliance in rooms contai-
ning gas, oil or sulphur. Do not install near
sources of heat.
• Do not use the appliance on sloping surfaces.
• Keep the appliance at least 2 ft (61cm) away
from flammable substances (alcohol etc) or
pressurised containers (e.g. aerosol cans).
• Do not rest heavy or hot objects on top of the
appliance.
• Always transport the appliance upright, NOT
on its side.
Remember to drain the condensate tank befo-
re moving the appliance.
If the appliance was transported on its side,
you must wait at least 6 hours before using it
(24 hrs is recommended).
ENVIRONMENTAL INFORMATION: This unit
contains fluorinated greenhouse gases cove-
red by the Kyoto Protocol. Avoid perforating
the refrigerant circuit of the appliance.
Maintenance and disposal must be carried out
by qualified personnel only (R410A,
GWP=1975).
• The materials used for packaging can be recy-
cled.
You are therefore recommended to dispose of
them in special differentiated waste collection
containers.
• Do not use the appliance outdoors.
• Do not use the appliance in laundry rooms.
Instructions
Read these instructions carefully before installing
and/or using the appliance.
• Keep these instructions.
If the appliance is transferred to other owners,
they should also be given these instructions.
• Failure to respect the instructions may result
in injury or damage to the appliance.
The manufacturer is not liable for damage
deriving from failure to follow these instruc-
tions.
Electrical connections
Before plugging the appliance into the outlet,
check that:
• The outlet, power supply corresponds to the
working voltage indicated on the rating plate.
• The power outlet, and electrical circuit are
adequate for the appliance.
• The power outlet, matches the plug. If this is
not the case, have the plug replaced by a qua-
lified electrician;
• The outlet is properly grounded.
INSTALLATION
Position the appliance in the room to be dehumi-
dified. A free space of at least 2 ft (61 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 2-4 in (5-
10 cm) should be left at the back of the appliance.
The condensate can be drained in one of the fol-
lowing ways:
A) Draining into the tank
The condensate can be drained directly into the
tank. The tank can be easily removed (fig.1).
When the tank is full, remove (fig.1) and empty it
into a sink. When finished, replace it properly.
NOTE: The tank must be positioned porperly for
the unit to function.
If you hear the intermittent sound of the beep, it
means the tank is not in the proper position.
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 continuous drai-
ning.

5
1) Remove the continuous drain cap 1by turning
it counterclockwise then remove the rubber
stopper from the spout 2(fig. 2).
2) Insert the drain cap 1 in the condensate drain
hose (8) till the end (fig. 3) then screw the
cap into the spout. (fig. 4).
3) Make sure the end of the hose is no higher
than the spout (Fig. 3) or water could remain
in the tank. Make sure there are no kinks in
the hose (Fig. 5).
Keep the rubber stopper to close
the spout.
C) Continuous draining using the
pump (only on pump models)
The patented heavy-duty pump system allows
water removal of up to 13 ft (4m) in height.
If you want the water to flow directly to a drain,
connect the condensation discharge tube supplied
(9) to the connection pipe located on the
lower front part of the unit unit (you will first need
to remove the stopper labeled PUMP) (fig. 6).
Select the dehumidifying function and press the
PUMP button.
Note: With the condensation discharge hose
missing and the pump switched ON, the display
will show the symbol PUMP blinking.
To eliminate this problem:
• Check the hose is correctly positioned;
• Disconnect and reconnect the plug.

CLEANING AND
MAINTENANCE
Always unplug the appliance from the power out-
let before performing any cleaning or maintenan-
ce 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 pro-
ducts 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 filter, pull it down as shown in figu-
re.
If the appliance is not used for long
periods
• After unplugging the appliance from the
power outlet, empty the tank.
• Clean and reposition the filter.
• Cover the appliance with a plastic bag to pro-
tect it from dust.
