The Refrigerant
To realize the function of the air conditioner unit, a special refrigerant circulates in the system.
The refrigerant is the fluoride R32 = 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, R32 is a non-polluting refrigerant with no harm to the
ozonosphere and a lower effect upon the greenhouse effect. R32 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 X m2. (Please
refer to table "a" in section of " Safety Operation of Inflammable Refrigerant" for Space X.)
For repairs, strictly follow manufacturer’s instructions only for appliances filled with R32 flammable gas.
Be aware that refrigerants do not have any odour.
Appliance filled with flammable gas R32.
Before using the appliance, read the owner’s manual.
Before installing the appliance, read the installation manual.
Before repairing the appliance, read the service manual.

effects.

Do not cut or damage the power
cords and control cables. If the
power cable and the cable of the
control signal are damaged, they
must be replaced by a
professional technician.

The power supply must be
equipped with a special circuit to
prevent fire.
Otherwise, it may result in fire or
electric shock.

the air conditioner is not used for
a long time
Otherwise, the accumulation of
dust can cause overheating.

Do not damage the power cord or
use an unauthorized cable.
Otherwise, it may cause
overheating or fire.

When cleaning the unit, stop
operation and turn off the power.
Otherwise, may occur electric
shock or damage.

The voltage rating of this product
is 220 - 240V, 50Hz. The
compressor vibrates strongly if
the voltage is too low, causing
damage to the cooling system.
The electrical components are
easily damaged if the voltage is
too high.

Do not attempt to repair the air
conditioner yourself.
An improper repair can cause fire
or electric shock. For this reason,
it is advisable to contact a service
center for repairs.

Check if the installed media is
sufficiently stable.
If damaged, it can cause the
equipment to fall and cause
injury.

Do not climb on the outdoor unit
or place anything on it.
