Appropriate use
This is a household appliance only.
Use this appliance only as described in this instruction manual.
These instructions are not intended to cover every possible con-
dition and situation that may arise. Common sense and caution
must be used when installing, operating and maintaining any
electrical appliance.
General safeguards
• Do not install the appliance in rooms containing gas, oil or
sulphur or near sources of heat.
• Do not use the appliance on sloping surfaces.
• Keep the appliance at least 50 cm away from ammable
substances (alcohol, etc.) or pressurised containers (e.g.
aerosol cans).
• Do not rest objects on top of the appliance.
• When transporting, the unit must remain upright or rest-
ing on one side. Drain the condensate tank before moving
the appliance. After transporting, wait at least 1 hour be-
fore using the appliance.
• R 134a is a refrigerant that complies with European eco-
logical standards; nevertheless, it is recommended not to
pierce the cooling circuit of the machine. At the end of its
useful life, deliver the appliance to a special waste collec-
tion centre for disposal.
ENVIRONMENTAL INFORMATION: This unit contains uor-
inated greenhouse gases covered by the Kyoto Protocol.
Maintenance and disposal must be carried out by qualied
personnel only (R134A, GWP=1300).
The materials used for packaging can be recycled. You are there-
fore recommended to dispose of them in special dierentiated
waste collection containers.
• Do not use the appliance outdoors.
• Do not obstruct the entrances and exits of air.
• Do not use the appliance in laundry rooms.
Electrical connections
After transporting the appliance, wait at least an hour before
turning it on.
Before plugging the appliance into the outlet, check that:
• The mains voltage corresponds to the operating voltage
stated on the rating plate.
• The mains socket and the electrical supply line are ade-
quate for the required load.
• The power outlet matches the plug. If this is not the case,
have the plug replaced by a qualied electrician
• The outlet is properly grounded.
Operating instructions
Read these instructions carefully before using the appliance.
• Keep these instructions.
If the appliance is transferred to other owners, they should
also be given these instructions.
• Failure to follow these instructions may result in injuries
and equipment damage.
The manufacturer is not liable for damages resulting from
failure to follow these Instruction for Use.
• Please refer to the guarantee leaet for contact details.
Please note!
Keep these Instructions for Use. If the appliance is transferred
to other owners, they should also be given these instructions.
INSTALLATION
Position the appliance in the room to be dehumidied. A free
space of at least 50 cm must be left at the front of the dehu-
midier, so as not to block the air outlet. For ecient ventilation
a space of about 5-10 cm should be left at the back of the ap-
pliance. 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 continuous draining.
1) Remove the continuous drain cap by turning it counter-
clockwise then remove the rubber stopper from the spout
2 (Fig. 2).
3) Apply the accessory tube to the spout as shown in Figure 3.
4) Make sure the end of the hose is no higher than the spout.
Otherwise the water will ow into the tank of the appli-
ance (Fig. 4).
Make sure there are no kinks in the hose.

INDICATOR LIGHTS
Tank control light
(Tank control system)
This dehumidier is equipped with a device that monitors the
correct functioning of the appliance.
The corresponding indicator light, located on the control panel,
turns 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 positioned incorrectly:
position it properly
4. in continuous drain:
the hose is obstructed or the dierence in level is too great
(the water continues to be discharged into the tank)
remove the obstruction.
Once the cause has been eliminated, the light goes out and the
appliance resumes operation.
Low temperature operation indicator light
When the room temperature is too low, the electronic low tem-
perature operation device is activated. The device makes the ap-
pliance operate by alternating dehumidication cycles and fan
only cycles, thus avoiding the formation of frost. For frequent
use in cold environments, it is recommended to heat the room
at the same time, even slightly. This allows the dehumidier to
operate in conditions that ensure better performance and faster
dehumidication.

CLEANING AND MAINTENANCE
Always remove the plug from the power socket before perform-
ing any cleaning or maintenance operations. For safety reasons,
never wash the dehumidier using a water jet.
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 the appliance with insecticides or similar. These
could cause the plastic parts to warp.

( ) is turned o, otherwise empty the tank or position
it correctly.
• To turn the appliance on, press the ON/STAND BY button
.
• Press the “MODE” (B2) button to select the desired humid-
ity ( , , , ).
The appliance will adjust the humidity level according to
your choice:
Approx. 60% environment humidity
Approx. 50% environment humidity
Approx. 40% environment humidity
Selecting , the “dry” function is activated, ideal to speed up
the drying of clothes.

Cleaning the dust air lter
If the lter is dirty, air circulation is compromised and the ef-
ciency of dehumidifying is decreased. It is therefore good
practice to clean the lter at regular intervals. The frequency
depends on the environment and the duration of operation.
If the unit is used constantly or systematically, you are recom-
mended to clean the lter once a week.
• To remove the air lter, remove the grill and extract the lter
by pulling it (see Fig. 5).
• Use a vacuum cleaner to remove dust accumulations from
the lter. If the lter is very dirty, rinse well with lukewarm
water. The temperature of the water should not exceed 40˚C.
After washing the lter, allow it to dry completely before re-
inserting it.
If the appliance is not used for long periods
• After unplugging the appliance from the power socket,
empty the tank.
• Clean and reposition the lter.
• Cover the appliance with a plastic bag to protect it from dust.
DISPOSAL
The appliance must not be disposed of with house-
hold waste, but taken to an authorised waste separa-
tion and recycling centre.
