1. Safety Precautions
Before installing the unit, make sure you read all the
“Safety Precautions”.
The “Safety Precautions” provide very important
points regarding safety. Make sure you follow them.
GB
Please report to or take consent by the supply
authority before connection to the system.
Symbols used in the text
Warning:
Describes precautions that should be observed to prevent danger
of injury or death to the user.
Caution:
Describes precautions that should be observed to prevent damage
to the unit.
Warning:
• These appliances are not accessible to the general public.
• The unit must not be installed by the user. Ask the dealer or an
authorized company to install the unit. If the unit is installed
improperly, water leakage, electric shock or fire may result.
• Do not stand on, or place any items on the unit.
• Do not splash water over the unit and do not touch the unit with
wet hands. An electric shock may result.
• Do not spray combustible gas close to the unit. Fire may result.
• Do not place a gas heater or any other open-flame appliance
where it will be exposed to the air discharged from the unit.
Incomplete combustion may result.
• Do not remove the front panel or the fan guard from the outdoor
unit when it is running.
• Never repair the unit or transfer it to another site by yourself.
• When you notice exceptionally abnormal noise or vibration, stop
operation, turn off the power switch, and contact your dealer.
• Never insert fingers, sticks etc. into the air inlets or outlets.
• If you detect odd smells, stop using the unit, turn off the power
switch and consult your dealer. Otherwise, a breakdown, electric
shock or fire may result.
• This air conditioner is NOT intended for use by children or infirm
persons without supervision.
• If the refrigeration gas blows out or leaks, stop the operation of
the air conditioner, thoroughly ventilate the room, and contact
your dealer.
• This appliance is intended to be used by expert or trained users
in shops, in light industry and on farms, or for commercial use by
lay persons.
Symbols used in the illustrations
: Indicates a part which must be grounded.
• Young children must be supervised to ensure that they do not
play with the air conditioner.
• 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.
• 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.
• When installing or relocating, or servicing the air conditioner, use
only the specified refrigerant (R410A) to charge the refrigerant
lines. Do not mix it with any other refrigerant and do not allow air
to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of
abnormal high pressure in the refrigerant line, and may result in
an explosion and other hazards. The use of any refrigerant other
than that specified for the system will cause mechanical failure
or system malfunction or unit breakdown. In the worst case, this
could lead to a serious impediment to securing product safety.
Caution:
• Do not use any sharp object to push the buttons, as this may
damage the remote controller.
•
Never block or cover the indoor or outdoor unit’s air inlets or outlets
• Never wipe the remote controller with benzene, thinner chemical
rags, etc.
• Do not operate the unit for a long time in high humidity, e.g.
leaving a door or window open. In the cool mode, if the unit is
operated in a room with high humidity (80% RH or more) for a
2
long time, water condensed in the air conditioner may drop and
wet or damage furniture, etc.
.
• Do not touch the upper air outlet vane or the lower air outlet
damper during operation. Otherwise, condensation may form and
the unit may stop operating.
Disposing of the unit
When you need to dispose of the unit, consult your dealer.

Note (Only for wireless remote controller):
When using the wireless remote controller, point it towards the receiver on the indoor unit.
If the remote controller is operated within approximately 2 minutes after power is supplied to
the indoor unit, the indoor unit may beep twice as the unit is performing the initial automatic
check.
The indoor unit beeps to confirm that the signal transmitted from the remote controller has
been received. Signals can be received up to approximately 7 meters in a direct line from the
indoor unit in an area 45° to the left and right of the unit. However, illumination such as fluorescent lights and strong light can affect the ability of the indoor unit to receive signals.
If the operation lamp near the receiver on the indoor unit is blinking, the unit needs to be in-
spected. Consult your dealer for service.
Handle the remote controller carefully! Do not drop the remote controller or subject it to strong
shocks. In addition, do not get the remote controller wet or leave it in a location with high humidity.
To avoid misplacing the remote controller, install the holder included with the remote controller
on a wall and be sure to always place the remote controller in the holder after use.

■ According to a set temperature, cooling operation starts if the room
temperature is too hot and heating operation starts if the room
temperature is too cold.
■ During automatic operation, if the room temperature changes and
remains 1.5 °C or more above the set temperature for 3 minutes, the
air conditioner switches to cool mode. In the same way, if the room
temperature remains 1.5 °C or more below the set temperature for
3 minutes, the air conditioner switches to heat mode.
