ELECTRICAL CONNECTIONS
Before plugging the appliance into the mains socket, check that:
• The outlet’s power supply corresponds to the value indicated on the rating label on the back
of the appliance;
• The outlet and electrical circuit are adequate for the appliance;
• The outlet is a 3-hole grounded outlet . If this is not the case, you must choose another outlet.
Failure to follow these important safety instructions absolves the manufacturer of all liability.
The instructions below will enable you to prepare your air conditioner for operation as efficiently
as possible. Before use, make sure the air intake and outlet grilles are unobstructed.
The power cable must be replaced by a qualified professional only.
If you have a very large window
• in order to cover your window aperture,
use the additional window bracket with-
out holes extending it to the desired
dimension, then fix the bracket by using
the pins provided. When extracting the
window bracket and joining the two
pieces pay attention you do not cover the
hole or holes (depending on the model).

Operation
TURNING THE APPLIANCE ON
Plug into an outlet.
Two lines appear on the display indicating that the appliance is
in stand-by.
Press the ON/STAND-BY button (A). When turned on, the air con-
ditioner starts operating in the same mode as when it was turned
off.
Press the MODE button (B) until the light corresponding to the
desired mode lights up:
Light (O): air-conditioning mode
Light (P): dehumidifying mode
Light (N): fan mode
AIR CONDITIONING MODE
Ideal for hot muggy weather when you need to cool and dehu-
midify the room.
The display shows the inner temperature: the light (S) turns on.
To modify the set temperature, push the (E) or (F) button to reach
the desired temperature. The (T) light turns on and the (S) light
turns off. (To change from °F to °C or viceversa, press for few sec-
onds both button Eand F).
After 15 seconds, the inner temperature is shown on the display.
The (S) light turns on.
You can adjust the temperature only in air conditioning mode.
Then select the fan speed by pressing the FAN button (C) until the
light corresponding to the required fan speed lights up:
MAX: the air conditioner operates at maximum to achieve the
target temperature as rapidly as possible
MED: reduces noise levels while maintaining a comfortable
temperature
MIN: for silent operation
The most suitable temperature for the room during the summer
varies from 75°F to 81°F (24 to 27°C). You are recommended,
however, not to set a temperature much below the outdoor
temperature

9
Operation
FAN MODE
Adjust fan speed by pressing the FAN button (C) as described for the air-conditioning mode.
Remember that the higher the speed, the more air is filtered. If you select "MIN" speed, less air is
filtered but the appliance is also less noisy.
DEHUMIDIFYING MODE
Ideal for reducing the humidity in a room without lowering or raising the temperature (spring or
autumn, damp rooms, rainy spells, etc).
When the dehumidifying mode is selected, the light (P) comes on.
At the same time, the "MIN" fan speed light (M) comes on. In this mode, other speeds cannot be
selected.
PROGRAMMING THE TIMER
The timer can be used to delay appliance start up or shut down. This avoids wasting electricity by
optimising operating periods.
How to programme delayed start up
• Plug the appliance into a mains socket and press the ON/OFF button (A), then select the
required operating mode and other settings (temperature, fan speed, etc).
• Press the ON/OFF button (A) again to place the appliance in standby mode.
• Press the timer button (D). The timer light "H" flashes.
• Use the + (E) or - (F) buttons to set the number of hours delay before the appliance comes on.
The time increases or decreases in steps of one hour.
The indicator light (H) flashes until the appliance starts up.
You can set the appliance to come on with a delay of up to 12 hours.
To cancel the timer programme, press the timer button (D) again.
Light (H) stops flashing.
How to programme delayed shut down
• Delayed shut down can be programmed in any operating mode (air conditioning / fan/ dehu-
midifying).
• Press the timer button (D). The timer light "H" flashes.
• Use the + (E) or - (F) buttons to set the number of hours delay before the appliance goes off.
The time increases or decreases in steps of one hour.
The light (H) flashes until the appliance turns off as programmed.
At the set time, the air conditioner shuts down and remains in standby.
To cancel the timer programme, press the timer button (D) again.
Light (H) stops flashing.

To get the best from your air conditioner, fol-
low these recommendations:
• close the windows and doors in the room to
be air conditioned.
The only exception is when the appliance is
installed through a hole in the wall.
In this case, you are recommended to
leave a slight draught through a door or
window to guarantee correct ventilation.
• Protect the room from direct exposure to
the sun by partially closing curtains and/or
blinds to make the appliance much more
economical to run;
• Never rest objects of any kind on the air
conditioner;
• Never obstruct the air intake or outlet
grilles;
• Make sure there are no heat sources in the
room.

• Never use the appliance in very damp
rooms (laundries for example).
• Never use the appliance outdoors.
Tips
close doors and windows
close blinds or curtains
do not cover
the appliance
• Make sure the air conditioner is on a level
floor.

12
Before cleaning or maintenance, turn the
appliance off by pressing the ON/OFF button
(A) or in models with remote control unit, by
pressing the ON/OFF button , then always
unplug the appliance from the mains socket.
CLEANING THE CABINET
You should clean the appliance with a slight-
ly damp cloth then dry with a dry cloth.
For safety reasons, never wash the air condi-
tioner with water.
Precautions
Never use petrol, alcohol or solvents to clean
the appliance. Never spray insecticide liquids
or similar.
CLEANING THE AIR FILTERS
To keep your air conditioner working efficient-
ly, you should clean the dust filter every week
of operation.
The filter is housed in the intake grille.
To clean the filters, remove the filter as shown
in figure N.
22
Use a vacuum cleaner to remove the dust
collected on the filter.
If it is very dirty, immerse in warm water and
rinse a number of times.
The water should never be hotter than 40°C.
After washing, leave the filter to dry.
Put the filter back in its housing.
START OF SEASON CHECKS
Make sure the power cable and plug are
undamaged and the earth system is efficient.
Follow the installation instructions precisely.
END OF SEASON OPERATIONS
To drain all water from the circuit, remove the
cap from the drain hose on the back of the
appliance and allow the water to drain out
into a basin (figure O). When the appliance is
empty, replace the cap.
Clean the filter and dry thoroughly before
putting back.
