Air naturally contains a certain amount of water in the form of water vapour and this

determines its humidity level. However, the capacity of air to retain water vapour is limited and
depends on the temperature. The higher the temperature, the greater the quantity of water
vapour the air can retain.

The absolute humidity (A.H.) value indicates the quantity of water

vapour contained in 1 kg of air and is expressed in grams.

The relative humidity (R.H.) value
represents the actual quantity of water contained in 1 kg of air expressed as a percentage of
the maximum quantity which can be contained under the same environmental conditions.

In other words, the air in a room at a certain temperature could be considered as a container
with a capacity of, say, 10 litres. If this container were half filled with water, it would be 50% full
(relative humidity) and contain 5 litres of water (absolute humidity). When the container is
completely full, it is described as “saturated”, in other words, there is a relative humidity of
100%, and in this situation water start condensing (e.g. becoming water), creating damages
to walls and furniture.
Experts have established that the optimum relative humidity for our organism and to preserve
furniture and other objects varies between 45% and 60%. Ideally, rooms should therefore be
kept within these values.
A dehumidifier is an appliance that eliminates the excess of moisture on the air (see below).

There is another way to decrease the relative humidity level. It is by increasing the room
temperature. Increasing the temperature is equivalent to increasing the capacity of the
container. When the air is at a temperature of 20˚C, it is the equivalent of a 10 litre container,
while at 30˚C it is the equivalent of a 20 litre container. (see below).

Of course, just increasing the room temperature is not the solution to your excess
moisture/condensation problem. Just warming the air means that you keep the moisture
suspended in the air as vapour, but when the temperature drops, the water vapour forms
condensation again.
However, heating combined with dehumidification (as in the combined mode) especially at
low temperatures- e.g. below 100C, or when drying washing is very useful. It changes
condensation into water vapour , which can then be collected by the dehumidifier, in a fast
an effective way.
Dehumidifiers are the only real answer to controlling condensation and damp in the home.

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 particularly
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
fitted with handles making it easy to transport. The combined operation is particularly suitable for
drying clothes (COMBI DRYER function).

To ensure optimum results and maximum safety, read this instruction manual carefully
before installing and using the appliance.

Place the dehumidifier in a suitable position, a hallway or landing are generally good sites.

The appliance must be positioned so that the air intake and air outlet grills are at least 50 cm
away from any wall or obstacle to ensure adequate ventilation.

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. 1).
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) Remove the rubber bung from the spout (Fig. 2).

2) Make a hole in the tank inside the spout using a fine drill bit (8mm) (Fig. 2).

3) To fit the rubber hose to the spout, open the door, remove the tank, pass the drain hose
provided through the space between the door (at a slight angle) and the bottom of the
appliance, reposition the tank and fit the hose onto the spout (Fig. 3).

4) Close the door.

5) Make sure the hose is on the level otherwise the water will remain in the tank. Check
there are no kinks in the hose.

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. The power light comes on to show the appliance
is connected to the mains.

2) Check that the “tank full/no tank” indicator light is off.

3) Turn the humidistat to the “CONTINUOUS” position and the mode selector to the
“DEHUMIDIFICATION” position. The dehumidification pause light comes on during the first
three minutes (safety device), followed by the dehumidification light.

4) Select maximum or minimum fan speed (the relevant light comes on).

When the humidity in the room has reached the required level, slowly turn the humidistat knob
anticlockwise until the dehumidifying light goes out. The dehumidifier will then keep the
humidity in the room at the selected level automatically.

Note: When dehumidifying, the appliance not only dehumidifies but also slightly warms the air

(1-2°C hotter than room temperature)

How to heat

1) Plug the appliance into a mains socket.

2) Turn the thermostat knob to position 5.

3) Turn the mode selector to the “HEATING” position. The heating light comes on and the
appliance starts up.

4) Select the economy ( /

1 = 800 W) or maximum ( /2 = 1600 W) heating level on the

speed/heat selection button (the corresponding light comes on).

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) Turn the humidistat knob to the “CONTINUOUS” position.

4) Rotate the mode selector to the “COMBI” position. The ( )light comes on together with
the dehumidification pause light for the first three minutes (safety device), followed by the
dehumidification light.

5) Select maximum or minimum fan speed (and consequently the electrical power). In this
mode, the electrical power will be 1,990 W or 1.190 W.

6) When the humidity in the room has reached the required level, slowly turn back the
humidistat knob anticlockwise until the dehumidifying and heating lights go out. The
dehumidifier will then keep the humidity at the set level.

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 heater will continue to work.

Selecting operating modes

DE320GB 28-05-2001 16:59 Pagina 18

Selecting operating modes / Cleaning

Turbo power

1) Plug the appliance into a mains socket.

2) Check that the “tank full/no tank” warning light is off.

3) Rotate the mode selector to the “TURBO” position. The heating light comes on together
with the maximum, minimum and (for the first three minutes) dehumidifying standby lights;
the heating function at maximum power (1600W) starts up; three minutes after (safety
device) the dehumidifying light come on and the “continuous” dehumidifying function
comes on. The electric power will be 1.990W.

With the Turbo Power function selected, the appliance automatically sets the maximum
humidity level and temperature.

Maintenance

Always remove the plug from the power socket before performing any cleaning or maintenance
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 operation. If the unit is used constantly or systematically, you
are recommended to clean the filter once a week.

• It is good practice to clean the filter weekly.

• To remove the air filter, extract by pulling it as shown in 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 should not exceed 40˚C. After washing the
filter, allow to dry completely before putting it back in the appliance.

If the appliance is not used for long periods

• Unplug from the mains socket and empty the tank.

• Clean and reposition the filter.

• Protect the appliance from dust by covering with a large plastic

bag.
