The Refrigerant R290
To realize the function of the air conditioner unit, a special refrigerant circulates in the
system. The refrigerant is the fluoride R290 = 3 GWP (Global warming potential). This
refrigerant is flammable and inodorous. It can lead to explosions under certain
conditions, however the flammability of this refrigerant is very low and it can be ignited
only by fire.
Compared to other common refrigerants, R290 is a non-polluting refrigerant with no
harm to the ozonosphere and a no effect upon the greenhouse effect. R290 has very
good thermodynamic features which lead to a really high energy efficiency. The units
therefore need less filling.
Warning:
Do not try to accelerate the defrosting process or to clean the appliance in different ways other
than those recommended by the manufacturer. Should repair be necessary, contact your
nearest authorized Argoclima Service Centre. Any repairs carried out by unqualified personnel
may be dangerous. The appliance has to be stored in a room that doesn’t have any
continuously operating ignition sources. (for example: open flames, an operating gas
appliance or an operating electric heater.) Do not pierce or burn.
Appliance has to be installed, operated and stored in a room with a floor area larger than 7 m
2
.
For repairs, strictly follow manufacturer’s instructions only for appliances filled with R290
flammable gas. Be aware that refrigerants do not have any odour.

WARNING!
The air conditioner must be positioned at least 50 cm from the wall
or any other obstacles, on a flat and stable surface so as to avoid
water leaks.
The air conditioner is fitted with a system for protecting the
compressor from overload. This means that the compressor
only starts 3 minutes after its previous stoppage.
Please wait at least 3 minutes before starting the unit. This
helps prevent the compressor from being damaged.
WARNING!
In the event of an anomaly, switch the appliance off and unplug
it from the socket. Do not dismantle or attempt to repair or
modify the product. In the event of a malfunction, contact the
service centre directly.
WARNING!
Do not expose the air conditioner to direct sunlight, as the
colour of the materials may change; moreover, the appliance
may overheat causing the protection mechanism to intervene
and switch the appliance off.
Do not use insecticides, oils, detergents or spray paints near
the appliance; do not use aggressive chemical detergents to
clean the casing: this may damage the finish and colour.

HOW TO USE THE APPLIANCE
This appliance can be used for cooling, dehumidifying and ventilation purposes.
Before using the appliance, leave it standing erect for at least two hours.
When switching between modes, the fan continues to turn but the compressor stops: the compressor will re-start after 3
minutes. This delay protects the compressor from potential damage.
THE DRAINAGE TUBE MUST BE CONNECTED to the appliance AT ALL TIMES: the only exception is when the
appliance is used in dehumidification mode only, in which case the appliance should be left to discharge directly
into the room for maximum efficiency (see the “Dehumidification Mode” paragraph).
Clean the air filters under the easily removable rear grille regularly to keep the air conditioner working efficiently.

OPERATING MODES
1. COOLING MODE
The “Cool” LED on the control panel will turn on.
The temperature can be adjusted to between 16 °C and 31 °C.
In this mode, each time the ON/OFF button is pressed the unit switches off, the appliance saves the temperature
setting and retains this setting when it is switched on again.
In this mode, the fan speed can be adjusted and the Timer and SLEEP functions can be set.
For more silent operation, run the fan at low speed.
2. DEHUMIDIFICATION MODE (DRY)
 Press the MODE button to select the dehumidification mode.
 The temperature is controlled by the electronic board and cannot be adjusted.
 In this mode, each time the ON/OFF button is pressed the unit switches off, the appliance saves the settings and
retains them when it is switched on again.
 The fan speed is set to low and cannot be adjusted.
NOTE
The air conditioner does not cool the room when operating as a dehumidifier.
When the appliance is used as a dehumidifier, the flexible pipe must not be connected.
For maximum dehumidification efficiency, leave the rear discharge attachment free to discharge directly into
the environment.
The dehumidification mode is recommended during autumn and winter.
If used during summer, it is best to leave the flexible pipe attached so that the hot air is discharged towards
the outside rather than into the room.
During dehumidification, continuous drainage should be implemented (see the next chapter, “HOW TO ELIMINATE
CONDENSATE”).
3. FAN MODE
 Press the MODE button to select ventilation until the corresponding icon appears.
 In this mode, the fan speed can be adjusted.
 The temperature cannot be adjusted.
HOW TO ELIMINATE CONDENSATE
Manual drainage Cooling
This appliance automatically vaporises condensate in the cooling mode.
Ensure that when the unit is operating in cooling mode, the rubber caps
closing the drainage holes on the rear of the appliance are properly
positioned.
When the air conditioner operates in cooling mode, there is no need for
continuous condensate drainage; only in specific weather conditions with very
high air humidity levels may water deposit inside the unit. When the container
is full, the “Full” LED (full tank) lights up on the control panel to signal that full
status and block the appliance’s operation.
To empty the container, switch the air conditioner off and unplug it. Remove
the cap form the rear drainage hole and direct it over a normal drain.
Ensure that the tube is not twisted or bent. The tube must slope downwards.
Re-close the drainage hole with the cap and resume use of the air conditioner.
