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. 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 surfaces evaporates into the
air to be collected by the dehumidifier.
Problems and repairs
In the event of problems, first try and resolve them by reading the
information given in the "Troubleshooting" section on page 11.
If the appliance requires repair, always contact a Customer
Experience - see enclosed guarantee.
Always insist on original spare parts. Repairs carried out by
unauthorized personnel may be dangerous and invalidate the
guarantee.
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 appliance.
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 instructions.

INSTALLATION
Position the appliance in the room to be dehumidified. 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 following 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 properly 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 draining.
1) Remove the continuous drain cap 1 by 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;
• Switch the appliance off by pressing the “ON/STAND-
BY “ button .
• Disconnect and reconnect the plug.

CLEANING AND MAINTENANCE
Always unplug the appliance from the power outlet 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 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 figure 7.
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 protect it from
dust.

ELECTRICAL REQUIREMENTS
The flexible mains lead is supplied connected to a B.S. 1363 fused plug
having a fuse of 13 amp capacity.Should this plug not fit the socket outlets
in your home, it should be cut off and replaced with a suitable plug, following the procedure outlined below.
Note: Such a plug cannot be used for any other appliance and should
therefore be properly disposed of, (having removed the fuse) and not left
where children might find it and plug it into a supply socket - with the
obvious consequent danger.
If the plug is a moulded-on type the fuse cover must be refitted. If the fuse
cover is lost, the plug must not be used until a replacement cover is
obtained. The colour of the correct replacement fuse cover is that of the
coloured insert in the base of the fuse recess or elsewhere on the plug.
Always state this colour when ordering a replacement fuse cover.
N.B. We recommend the use of good quality plugs and wall sockets that
can be switched off when the machine is not in use.
important: the wires in the mains lead fitted to this appliance are coloured
in accordance with the following code:
As the colours of the wires in the mains lead of this appliance may not
correspond with the coloured markings identifying the terminals in your
plug, proceed as follows:
The wire which is coloured green and yellow must be connected to the
terminal in the plug which is marked with the letter E or by the earth
symbol or coloured green or green and yellow.
The wire which is coloured blue must be connected to the terminal which
is marked with the letter N or coloured black.
The wire which is coloured brown must be connected to the terminal
which is marked with the letter L or coloured red.
When wiring the plug, ensure that all strands of wire are securely retained
in each terminal. Do not forget to tighten the mains lead clamp on the plug.
If your electricity supply point has only two pin socket outlets, or if you are
in doubt, consult a qualified electrician.
Should the mains lead ever require replacement, it is essential that this
operation be carried out by a qualified electrician and should only be
replaced with a flexible cord of the same size.
Only 13amp replacement fuses which are asta approved to B.S. 1362 should
be fitted. This appliance conforms to the Norms EN 55014 regarding the
suppression of radio interference.
This appliance MUST be Earthed
