During the summer, optimum comfort is achieved with a temperature of around 24 °C and 50%
relative humidity.
An air conditioner removes moisture and heat from the room where it is located. One advantage
of portable air conditioning units over fitted models is that they can be moved from one room to
another in the home or even transferred between different buildings.
The hot air in your room is passed through
a coil cooled by refrigerant gas, remo-
ving excess heat and moisture
before being discharged again
into the room.
In single unit models, a small
amount of this air is used to
cool the refrigerant gas,
then the hot and moist air is
discharged outside.

Preparation for use
HOW TO USE THE AIRCONDITIONER WITH WATER
These air conditioners can use both air and water to cool the condenser (the hot part) of the air
conditioner.
To utilise the full potential of your air conditioner, the tank needs to be filled with water. The water
is used. To increase the cooling power and reduce the noise level and energy consumption of the air
conditioner. The water that is used in then expelled from the machine as water vapour through the
exhaust hose (it does not go into room).
Always use clean top water (which doesn’t contain salts). As a rule the water will usually last about 8
hours however this depends on the conditions within the room, such as temperature, humidity, insula-
tion and aspect and number of people. In turbo mode the water will also be used more quickly.
You may also use the airconditioner on air cooling only (without filling the water tank . If you only requi-
re the lower cooling power.

A) To open the front panel
grip either side of the
panel and gently pull the
panel towards you and
upwards. Remove the tank
Lifting it forward.

B) Turn the tank upside down
and remove the plug,
remove the extendible
tube and fill the tank, lea-
ving it on the ground.
C) After completing the fil-
ling procedure, replace
the extendible hose,
replace the cap and
screw it in tightly. Return
the tank to its place, with
the writing FRONT clearly
visible. Carefully hold the
panel in the centre and
lower to its closed posi-
tion.
During the "water functioning" operation and in particularly silent locations (eg the bedroom) a
slight gurgling sound may be heard. This is completely normal.
IN HIGH HUMIDITY CONDITIONS
Water is extracted from the air in the room, this water is also used to cool the condenser. When
the humidity is particulary high an excess of water may buid up in the internal tank. This can be
drained by removing the bung from the drain hose and draining into a suitable receptacle.
11
IMPORTANT: if the room temperature is 32°C or over the airconditioner must be operated with with
water in the tank.

Turning on and setting the timer
ELECTRICAL CONNECTION
Before plugging in check that:
•the mains supply corresponds to the
power supply shown on the rating plate;
•the socket and the mains lead correspond
to the power requirements of the applian-
ce;
•the socket is suited to the plug, otherwise
have the socket replaced;
• the socket is properly grounded.
The manufactures cannot be held responsi-
ble for any damages due to failure in fol-
lowing normal safety procedures.
Replacement of the power cable must be
carried out by qualified personnel.
SETTING THE TIMER (if supplied)
The programmer/timer , like all clocks,
must be set to the exact time. If for example
it is 4.00 pm. (16.00), turn the dial in a clockwi-
se direction (following the direction of the
arrow) until the number 16 is lined up with the
triangular pointer (the arrows indicates 4:00
P.M. approximately ).

N.B.: Never turn the dial in an anti-clockwise
direction!
The timer is in effect, an electric clock
and works only if the plug is connected to
the power supply. Whenever the plug is
disconnected or there is a power failure,
the programmer stops (the clock is then
“slow”) and must be re-set.
PROGRAMMED MODE
1) Set the operating times by pushing out the not-
ches on the dial corresponding to the period
required (each notch represents 15 mins.)
2) Press the TIMER key , the signal light
will come ON.
3) Make sure that the timer indicates the cor-

Selecting functions
AIR CONDITIONING FUNCTIONS
To turn the unit on in air conditioning mode,
proceed as follows:
1. Press the button (the signal light “I”
will come on).
2. Rotate the function selector dial anti-
clockwise:
•Place the large star symbol in line with
the reference mark to operate the unit in
air conditioning mode at maximum fan
speed (the signal light will come on,
and then, after 3 minutes the signal light
will come on ).
•Place the small star symbol in line with
the reference mark to operate the unit in
air conditioning mode at minimum fan
speed (the signal light will come on,
and then, after 3 minutes the signal light
will come on ).
3. Now set the required temperature by rota-
ting the room thermostat dial .
Note
The temperature is not expressed in degrees.
We recommend that you turn the thermostat
dial to the maximum position. When the desi-
red room temperature has been reached,
slowly turn the thermostat in a clockwise
direction until it arrives at the position where a
click can be heard. The signal lights and
(or ) will turn off.
The temperature selected in this way will
automatically be regulated and maintained,
and save energy. When regulating the ther-
mostat, the air conditioning function is tem-
porarily interrupted and the unit continues to
operate in fan only mode. In this way, the
appliance keeps the air temperature within
the room even.
Delay on Start Up
1. A special safety device will delay the start
of air conditionig by approximately 3 to 5
minutes when switching between func-
tions or on initial start up.
2. You may also experience a slight delay
between changing from one function to
another.

Descaling
When the scale deposits become excessive
(on average, after about 400 hours of opera-
tion) or in any case, at least once each sea-
son, it is very important to proceed with the
decalcification of the appliance as described
below.
To remove the scale from the appliance, you
need:
•250 ml of descaling liquid
• 750 ml of clean water
(corresponding to a diluted solution of 75%)
Proceed as follows:
1) Remove the tank from the appliance
and drain the water remaining in the col-
lection reservoir by using the draina-
ge hose (fig. H).
2) Close the drainage hose . Pour 250 ml
of decalcifying liquid and 1 litre of clean
water into the collection reservoir
which is found under the tank (fig. I), on
the bottom of the appliance.
3) Operate the air conditioner for about half
an hour.
4) After this, drain out all of the liquid remai-
ning in the collection reservoir and rinse
thoroughly. During the rinsing process, the
drainage hose must be open and the
appliance functioning.
5) Unplug the appliance from the mains and
clean the collection reservoir thoroughly
with a clean cloth.
6) After cleaning the collection reservoir, the
