into the air inlet or outlet. This may cause
injury, since the fan may be rotating at high
speeds.
• DO NOT use a flammable spray such as hair
spray, lacquer or paint near the unit. This
may cause fire or combustion.
• Do not use means to accelerate the
defrosting process or to clean, other than
those recommended by the manufacturer.
• The appliance shall be stored in a room
without continuously operating ignition
sources (for example: open ames, an
operating gas appliance or an operating
electric heater).
• The appliance shall be stored so as to
prevent mechanical damage from occurring.
General
Introduction
Failure to observe a warning may result in death. The appliance must be
installed in accordance with national regulations.
.
Failure to observe a caution may result in injury or equipment damage.
WARNING
CAUTION
• Be aware that the refrigerants may not
contain an odour.
• Compliance with national gas regulations
shall be observed.
• Keep ventilation openings clear of
obstruction.
• DO NOT pierce or burn.

Safety Precautions
CAUTION
• DO NOT touch the air outlet while the swing
flap is in motion. Fingers might get caught
or the unit may break down.
• DO NOT inspect the unit by yourself. Ask an
authorized dealer to perform the inspection.
• To prevent product deterioration, do not use
the air conditioner for preservation purposes
(storage of food, plants, animals, works of
art, etc.).
• This appliance can be used by children aged
from 8 years and above and persons with
reduced physical, sensory or mental
capabilities or lack of experience and
knowledge if they have been given
supervision or instruction concerning use of
the appliance in a safe way and understand
the hazards involved. Children shall not play
with the appliance. Cleaning and user
maintenance shall not be made by children
without supervision.
• DO NOT operate the air conditioner with
wet hands. It may cause electric shock.
• DO NOT touch the evaporator coils inside
the indoor unit. The evaporator coils are
sharp and may cause injury.
• DO NOT place items that might be aected
by moisture damage under the indoor unit.
Condensation can occur at a relative
humidity of 80%.
• DO NOT expose heat-producing appliances
to cold air or place them under the indoor
unit. This may cause incomplete combustion
or deformation of the unit due to the heat.
• After long periods of usage, check the
indoor unit to see if anything is damaged. If
the indoor unit is damaged, it may fall and
cause injury.
• If the air conditioner is used together with
other heating devices, thoroughly ventilate
the room to avoid oxygen deficiency.
• DO NOT climb onto or place objects on top
of the outdoor unit.
• DO NOT operate the air conditioner when
using fumigant insecticides. The chemicals
may become layered with the unit and
endanger those who are hypersensitive to
chemicals.
• DO NOT let children play with the air
conditioner.
• DO NOT operate the air conditioner in a wet
room (e.g. bathroom or laundry room). This
can cause electrical shock and cause the
product to deteriorate.

Features
Default Setting
When the air conditioner restarts after a power
failure, it will default to the factory settings
(AUTO mode, AUTO fan, 24°C (76°F)). This
may cause inconsistencies on the remote
control and unit panel. Use your remote
control to update the status.
Auto-Restart (some models)
In case of power failure, the system will
immediately stop. When power returns, the
Operation light on the indoor unit will flash. To
restart the unit, press the ON/OFF button on
the remote control. If the system has an auto
restart function, the unit will restart using the
same settings.
Energy Saving Tips
• DO NOT set the unit to excessive temperature levels.
• While cooling, close the curtains to avoid direct sunlight.
• Doors and windows should be kept closed to keep cool or warm air in the room.
• DO NOT place objects near the air inlet and outlet of the unit. This will reduce the efficiency of
the unit.
• Set a timer and use the built-in SLEEP/ECONOMY mode if applicable.
• If you don’t plan to use the unit for a long time, remove the batteries from the remote control.
• Clean the air filter every two weeks. A dirty filter can reduce cooling or heating efficiency.
• Adjust louvers properly and avoid direct airflow.
Louver Angle Memory Function (Optional)
Some models are designed with a louver angle
memory function. When the unit restarts after a
power failure, the angle of the horizontal louvers
will automatically return to the previous position.
The angle of the horizontal louver should not be
set too small as condensation may form and drip
into the machine. To reset the louver, press the
manual button, which will reset the horizontal
louver settings.
Refrigerant Leak Detection System
(some models)
In the event of a refrigerant leak, the LCD screen
will display “EC” and the LED indicator light will
flash.
Closing curtains during heating also
helps keep the heat in Doors and windows should be kept closed

Care And Maintenance 4
Safety Precautions
• Contact an authorized service technician for
repair or maintenance. Improper repair and
maintenance may cause water leakage,
electrical shock, or fire, and may void your
warranty.
• DO NOT substitute a blown fuse with a
higher or lower amperage rating fuse, as this
may cause circuit damage or an electrical fire.
• Make sure the drain hose is set up according
to the instructions. Failure to do so could
cause leakage and result in personal
property damage, fire and electric shock.
• Make sure that all wires are connected
properly. Failure to connect wires according
to instructions can result in electrical shock
or fire.
Unit Maintenance
BEFORE CLEANING OR
MAINTENANCE
• Always turn o your air conditioning system
and disconnect the power supply before
cleaning or maintenance.
•
DO NOT use chemicals or chemically treated
cloths to clean the unit.
•
DO NOT use benzene, paint thinner,
polishing powder or other solvents to clean
the unit. They can cause the plastic surface
to crack or deform.
•
DO NOT wash the unit under running water.
Doing so creates an electrical hazard.
•
DO NOT use water hotter than 40°C (104°F)
to clean the front panel. This can cause the
panel to become deformed or discolored.
• Clean the unit using a damp, lint-free cloth
and neutral detergent. Dry the unit with a
dry, lint-free cloth.
How To Clean The Air Filter
The filter prevents dust and other particles from
entering the indoor unit. Dust buildup can reduce
the efficiency of the air conditioner. For optimum
efficiency, clean the air filter every two weeks or
more frequently if you live in a dusty area. Replace
the filter with a new one if it’s heavily clogged and
cannot be cleaned.
WARNING: DO NOT REMOVE OR
CLEAN THE FILTER BY YOURSELF
Removing and cleaning the filter can be
dangerous. Removal and maintenance must be
performed by a certified technician.
NOTE: In households with animals, you will
have toperiodically wipe down the grille to
prevent animal hair blocking airow.
