should be forbidden to children. Unforeseeable
accidents could happen.
• The user must protect the indoor unit with a
fuse of suitable capacity for the maximum in-
put current or with another overload protection
device.
• The ratings of the fuse installed in the built
incontrol unit are T 5A / 250V
• The air conditioner must be installed by
professional or qualied persons.
• Check that air cannot enter the refrigerant sys-
tem and check for refrigerant leaks when mo-
ving the air conditioner.
• Ensure that the mains voltage corresponds to
that stamped on the rating plate . Keep the sw-
itch or power plug clean. Insert the power plug
correctly and rmly into the socket, thereby
avoiding the risk of electric shock or re due to
insucient contact.
• If the appliance gives o smoke or there is a
smell of burning, immediately cut o the power
supply and contact the Service Centre.
• The appliance must be tted with means for
disconnection from the supply mains having
a contact separation in all poles that pro vide
full disconnection under overvoltage category
III conditions, and these means must be
incorporated in the xed wiring in accordance
with the wiring rules.
• Do not install the appliance at a distance of
less than 50 cm from inammable substances
(alcohol, etc.) Or from pressurised containers
(e.g. spray cans).
• If the appliance is used in areas without the
possibility of ventilation, precautions must be
taken to prevent any leaks of refrigerant gas
from remaining in the environment and creat-
ing a danger of re
• The packaging materials are recyclable and
should be disposed of in the separate waste
bins . Take the air conditioner at the end of its
useful life to a special waste collection centre
for disposal.

SAFETY PRECAUTIONS
CAUTION: Risk of re/ammable material
CAUTIONS
• In no way alter the characteristics of the appli-
ance.
• Do not leave windows or doors open for long
when tje air conditioner is operating.
• Do not climb onto or place any objects on the
outdoor unit.
• Do not bend , tug or compress the power cord
since this could damage it. Electrical shocks or
re are probably due to a damaged power cord.
Specialised technical personnel only must repl-
ace a damaged power cord.
• Do not touch the appliance when barefoot or
parts of the body are wet or damp.
• Do not climb onto or place any heavy or hot
objects on top of the appliance.
• Do not obstruct the air inlet or outlet of the
in door or the outdoor unit. The obstruction
of these openings causes a reduction in the
operative eciency of the conditioner with
possible consequent failures or damages.
• Do not install the appliance in environments
where the air could contain gas , oil or sulphur
or near sources of heat.
• This appliance is not intended for use by
persons (including children) with reduced
physical, sensory or mental capabilities, or
lack of experience and knowledge, unless they
have been given supervision or instruction
concerning use of the appliance by a person
responsible for their safety.
• A long direct exposition to the ow of cold air of
the conditioner could have negative eects on
plants and animals.
• Do not put the conditioner in contact with
water. The electrical insulation could be
damaged and thus causing electrocution.
• Do not direct the airow onto plants or animals.
• Never insert a stick or similar object into the
appliance. It could cause injury.

PART 2. OPERATING THE DEVICE
1. SPECIAL FEATURES
Refrigerant leak detection function
With this new function, the detection of refrigerant leakage by the outdoor unit will be alerted by the
appearance of the„EC” symbol on the display screen and the LEDs ashing.
Louver position memory function (optional)
This function allows you to remember the opening angle of the blind within the safe range. If the louver
position is outside this range, the device will remember the safety angle limit value.
When the manual control button is pressed or the power cord plug is pulled out and reinserted into the mains
socket, the blinds will revert to the standard setting.
We recommend not to set a low opening angle of the louvers as this may cause condensation and water
dripping from the surface of the air conditioner.
Self cleaning function (optional)
• When the heating unit is turned o, the unit will automatically clean the evaporator and keep it clean until
the next operation.
• Diagram of how the device works during self-cleaning: Fan mode (FAN), fan speed - low (LOW) - heating
mode (HEAT), fan speed - low (cooling & heating units only) - fan mode - stop - o (OFF).
REMEMBER:
• The self-cleaning function can only be activated when the appliance is in cooling (AUTO COOL or FORCED
COOL) and DRY mode.
• It is recommended to run the unit in cooling mode for at least half an hour before activating the function.
Running the self-cleaning function will cancel the timer settings.
• If you press the SELF CLEAN button while cleaning the appliance, the unit will turn o.
Mold prevention function (optional)
• After turning o the unit working in COOL, DRY or AUTO (COOL) mode, the air conditioner will continue
working for 7-10 minutes (depending on the model) at low fan speed. The unit working in HEAT mode
after turning o will work for 30 seconds with low fan speed. Such behavior of the device will allow its
interior to dry out of the condensate formed and prevent the growth of mold.
• Do not restart the unit while the anti-mold function is active and the air conditioner is not turned o
completely.

PART 2. OPERATING THE DEVICE
REMEMBER
1. The device will achieve the highest eciency in the above temperature ranges. If the air conditioner
operates at temperatures outside the above mentioned range, some safety functions may be
activated, causing the device to operate unnaturally.
2. If the air conditioner is used for a long time in an environment with high humidity (exceeding 80%),
water droplets may drip. In this situation, it is recommended to set the maximum opening angle of the
vertical blinds (vertically to the oor) and start the fan at high speed (HIGH).
