Air always contains a certain amount of water in the air in the form of water vapour.
This amount of moisture is commonly known as the humidity.
The capacity of the air to hold water vapour increases with the 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, to control con-
densation within the home.
Experts have established that the optimum environmental conditions for our well being and
preserve objects are obtained between 40% and 60% relative humidity. Below these levels the
air can feel too dry and may cause skin complaints and even static electric shocks.
This new dehumidifier is a combined function appliance (dehumidifying and heating) able to
quickly and efficiently reduce the relative humidity in a room. Its combined function is particular-
ly suitable for obtaining a rapid effect at low temperatures (below 10˚C). In these conditions, the
heater evaporates the condensation formed by the water vapour on walls, furniture and objects,
allowing the humidity to then be eliminated efficiently by the dehumidifier. The compact unit is fit-
ted with handles making it easy to transport. The combined operation is particularly suitable for
drying clothes (COMBI DRYER function).
Impor tant
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 pro-
viding this service.
Disposing of a household appliance separately avoids possible negative consequences for the
environment and health deriving from inappropriate disposal and enables the constituent mate-
rials 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.

Instructions for fitting the wheels
1) Make sure the appliance is unplugged from the mains and the tank is empty
2) Remove the rubber caps from the base of the appliance by pulling them out, using pliers if
necessary (see Figure 1/1).
3) Fit the wheels by inserting the shafts into the holes (see Figure 1/2)
Note: When performing these operations, make sure the appliance is not tilted over 45°; in any
case, after fitting the wheels, wait at least one hour before using the appliance again.
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 humidifier, so as not to block the
air outlet. A space of around 5-10 cm should be left at the rear of the appliance for aeration.
Condensate can be drained in one of two ways:
A) Draining into the tank
The condensate can be drained directly into the tank located inside the appliance (fig. 2).
The tank can be easily removed and has a handle making it simple to carry and empty.
B) Continuous external draining
If the appliance is to be operated for long periods of time but you are unable to empty the tank,
you are recommended to use the continuous drain facility.
1) Drill the inside of the drain spout using a 7 mm dia. drill bit or removing the precut section
by pressing with a screwdriver or similar (Fig. 3).
2) Fasten the rubber hose to the spout. For models without drain hoses supplied, we sug-
gest you purchase a rubber hose around 1 m long, with an internal diameter of 9.5 mm.
3) The condensate drain hose must under no circumstances slope upwards, otherwise the
water may remain in the tank. Check there are no kinks in the hose (Fig. 4).
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
1) Plug the appliance into a mains socket.
2) Check that the “tank full/tank missing” light is off.
3) Select the or according to the desired dehumidifying power; the dehumidification
standby light remains on during the first 3 minutes (safety device), after which the dehu-
midification light switches on.
4) The humidistat knob is used to adjust the humidity level as desired (MIN/MED/MAX). When the
knob is on MIN, the dehumidifier will slightly reduce the humidity in the room; on MAX, on the
other hand, the appliance will considerably reduce the humidity in the room. Then turn the
humidistat to one of the positions available.
Turn the humidistat to the MAX position. When the humidity has reached the required level
(this can take several weeks), slowly turn the humidistat knob anticlockwise until the dehu-
midifying light goes out. The dehumidifier will then keep the humidity in the room at the
selected level automatically.
How to heat
1) Plug the appliance into a mains socket.
2) It is possible to adjust the room temperature by turning the thermostat knob on one of the
available position (MIN-MED-MAX). If you wish to heat the room, set the thermostat to the
temperature level desired.
3) Select the economy ( = 1250 W) or maximum ( = 2000 W) heating level on the func-
tion selector.
To easily select the right temperature level, we suggest you to operate as follows:
Turn the thermostat to position MAX
When the temperature in the room has reached the required level, slowly turn the thermostat
knob anticlockwise until the heating light goes out.
The thermostat will then keep the temperature in the room at the selected level automatically.
Combined mode, (dehumidifying + heating)
1) Plug the appliance into a mains socket.
2) Check that the “tank full/no tank” warning light is off.
3) Select maximum (combi MAX) or minimum (combi MIN) power level. Consequently the
electrical power will be 1030 W or 1530 W.
4) It is possible to adjust the desired room humidity temperature °C by turning the humidistat
and the thermostat, (see chapters “How to dehumidify” and “How to heat”)
Note: The appliance only stops completely when the level of humidity set is reached. If the
tank is full, the tankfull warning light comes on and the refrigerant circuit stops however
the heating function will continue to work.

Tank control system
This dehumidifier is fitted with a special device to ensure 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 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .replace the tank
3. the tank is in the wrong position . . . . . . . . . . . . . . . . . . . .position the tank correctly
4. in continuous drain: the hose is obstructed or the difference in level is
too great . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .remove the obstruction.
Once the cause has been eliminated, the light goes out and the appliance resumes operation.
Dehumidification light
This switches on when the machine is dehumidifying. The light remains on only when the appli-
ance is effectively dehumidifying; if the humidity in the room is already low enough, the light
will be off.
Dehumidification standby/low temperature operation light
The light switches on in the following two cases:
1) To signal a delay of around 3 minutes in the start-up of the appliance. This device protects
the compressor against too frequent starts and stops.
2) To signal low temperature operation. When the room temperature is too low, the electron-
ic low temperature operation device is activated. The device makes the appliance oper-
ate by alternating dehumidification 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 dehumidifier to operate in conditions that ensure
better performance and faster dehumidification.
Heating light
This switches on when the machine is heating. The light remains on only when the appliance is
effectively heating; if the temperature in the room is already high enough, the light will be off.

Always remove the plug from the power socket before performing any cleaning or mainte-
nance operations. For safety reasons, never wash the dehumidifier 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 paint to flake or
plastic parts to warp.
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 opera-
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 it as shown in fig. 5.
• 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 should not
exceed 40˚C. After washing the filter, allow it to dry up com-
If 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 so that dust does not build up.
