Start or stop the air conditioner with the remote con-
troller. Never use the power circuit breaker for this pur-
pose.
Otherwise, it may cause a fire or water leakage. Further-
more, if an automatic restart control is provided against
power failure and the power is recovered, the fan will rotate
suddenly and may cause injury.
Do not use the air conditioner in the atmosphere con-
taminated with oil vapor, such as cooking oil or
machine oil vapor.
Oil vapor may cause crack damage to the air conditioner,
electric shocks, or a fire.
Do not use flammable materials (e.g., hairspray or
insecticide) near the air conditioner.
Do not clean the air conditioner with organic solvents
such as paint thinner.
The use of organic solvents may cause crack damage to
the air conditioner, electric shocks, or a fire.
Do not use the air conditioner in places with excessive
oily smoke, such as cooking rooms, or in places with
flammable gas, corrosive gas, or metal dust.
Using the air conditioner in such places may cause a fire or
air conditioner failures.
Beware of a fire in case of refrigerant leakage.
If the air conditioner is not operating correctly, i.e. not gen-
erating cool or warm air, refrigerant leakage could be the
cause. Consult your local dealer for assistance. The refrig-
erant used for the air conditioner is safe and normally does
not leak. However, if the refrigerant leaks and gets in con-
tact with a naked burner, heater or cooker, it may generate
hazardous compounds. Turn off the air conditioner and call
your local dealer. Turn on the air conditioner after the qual-
ified service person makes sure to confirm that the leakage
is repaired.
Do not place objects, including rods, your fingers, etc.,
in the air inlet or outlet.
Injury may result due to contact with the air conditioner’s
highspeed fan blades.
Consult your local dealer regarding cleaning the inside
of the air conditioner.
Improper cleaning may cause breakage of plastic parts,
water leakage and other damage as well as electric shocks.
Be aware that prolonged, direct exposure to cool or
warm air from the air conditioner, or to air that is too
cool or too warm can be harmful to your physical con-
dition and health.
Consult your local dealer about installation work.
Doing the work yourself may result in water leakage, elec-
tric shocks or a fire.
Contact professional personnel about attachment of
accessories and be sure to use only accessories spec-
ified by the manufacturer.
If a defect results from your own workmanship, it may result
in water leakage, electric shocks or a fire.
Consult your local dealer regarding relocation and
reinstallation of the air conditioner.
Improper installation work may result in leakage, electric
shocks or a fire.
Be sure to earth the air conditioner.
Do not earth the air conditioner to a utility piping, lightning
conductor or telephone earth lead.
Imperfect earthing may result in electric shocks or a fire.
A high surge current from lightning or other sources may
cause damage to the air conditioner.
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in
electric shocks or a fire.
Be sure to use a dedicated power supply for the air
conditioner.
The use of any other power supply may cause heat gener-
ation, a fire, or air conditioner failures.
Consult your local dealer regarding what to do in case
of refrigerant leakage.
When the air conditioner is installed in a small room, it is
necessary to take proper measures so that the amount of
any leaked refrigerant does not exceed the concentration
limit in the event of a leakage. Otherwise, this may lead to
an accident due to oxygen depletion.
CAUTION
Children should be watched so that they do not play
with the indoor unit or its remote controller.
Accidental operation by a child may result in injury or elec-
tric shocks.
Do not allow a child to mount on the outdoor unit or
avoid placing any object on it.
Falling or tumbling may result in injury.
Do not let children play on or around the outdoor unit.
If they touch the unit carelessly, injury may be caused.
Be sure that children, plants or animals are not
exposed directly to airflow from the indoor unit, as
adverse effects may ensue.
Do not place flammable sprays or operate spray con-
tainers near the air conditioner as this may result in a
fire.
Do not wash the air conditioner or the remote control-
ler with water, as this may result in electric shocks or
fire.
Do not place water containers (flower vases, etc.) on
the indoor unit, as this may result in electric shocks or
a fire.
Do not put flammable containers, such as spray cans,
within 1 m from the air outlet.
The containers may explode because the warm air from the
indoor or outdoor unit will affect them.
Turn off the power when the air conditioner is not used
for long periods of time (only for R410A refrigerant).
Otherwise, the air conditioner may get hot or catch on a fire
due to dust accumulation.
Do not place objects in direct proximity of the outdoor
unit and do not let leaves and other debris accumulate
around the unit.
Leaves are a hotbed for small animals which can enter the
unit. Once in the unit, such animals can cause malfunc-
tions, smoke or a fire when making contact with electrical
parts.
To avoid electric shocks, do not operate with wet
hands.
Never touch the internal parts of the remote controller.
Touching certain internal parts will cause electric shocks
and damage to the remote controller. Consult your local
dealer about checking and adjustment of internal parts.
To avoid oxygen deficiency, ensure that the room is
adequately ventilated if equipment such as a burner is
used together with the air conditioner.

Do not leave the remote controller wherever there is a
risk of wetting.
If water gets into the remote controller there is a risk of elec-
trical leakage and damage to electronic components.
Do not remove the outdoor unit’s outlet side grille.
The grille protects against the unit’s high speed fan, which
may cause injury.
After prolonged use, check the unit stand and its
mounts for damage.
If left in a damaged condition, the unit may fall and cause
injury.
To avoid injury, do not touch the air inlet or aluminum
fins of the air conditioner.
Do not place objects that are susceptible to moisture
directly beneath the indoor or outdoor units.
Under certain conditions, condensation on the unit or refrig-
erant piping, air filter dirt or drain blockage may cause drip-
ping, resulting in fouling or failure of the object concerned.
Do not place appliances that produce naked flames in
places exposed to the airflow from the air conditioner
as this may impair combustion of the burner.
Do not block air inlets nor outlets.
Impaired airflow may result in insufficient performance or
trouble.
Do not use the air conditioner for purposes other than
those for which it is intended.
Do not use the air conditioner for cooling precision instru-
ments, food, plants, animals or works of art as this may
adversely affect the performance, quality and/or longevity
of the object concerned.
Do not install the air conditioner at any place where
there is a danger of flammable gas leakage.
In the event of a gas leakage, build-up of gas near the air
conditioner may result in a fire.
Carry out drain piping properly to ensure complete
drainage.
If drain piping is not carried out properly, drain will not flow
out. Then, dirt and debris may be accumulated in the drain
piping and may cause water leakage. If it occurs, stop the
air conditioner and call your local dealer for assistance.
Do not turn off the breaker unless you smell something
burning, or when doing repairs, inspection or cleaning
of the unit.
Refrigerant leakage cannot be detected otherwise. (Only
for R32 refrigerant)
Do not install in sealed, highly airtight spaces such as
soundproof chambers and room which was sealed up
the door (only for R32 refrigerant).
Do not use flammable substances (such as hairsprays
or insecticides etc.) near the unit.
It could cause electric shock, fire, or a misdetection of the
refrigerant sensor (only for R32 refrigerant).
Do not install in places filled with smoke, gas, chemi-
cals etc.
There is a possibility that the sensors inside the indoor unit
could detect these, and display a refrigerant leak abnormal-
ity (only for R32 refrigerant).
This unit is equipped with electrically powered safety
measures. To be effective, the unit must be electrically
powered at all times after installation, other than short
service intervals (only for R32 refrigerant).

Regarding wiring
• All wiring must be performed by an authorized
electrician.
To do wiring, ask your dealer. Never do it by yourself.
• Make sure that a separate power supply circuit
is provided for this air conditioner and that all
electrical work is carried out by qualified per-
sonnel according to local laws and regulations.
Pay attention to running noises, too
• Are the following places selected?
a. A place that can sufficiently withstand the
weight of the air conditioner with less running
noises and vibrations.
b. A place where the hot wind discharged from the
air outlet of the outdoor unit and the running
noises do not cause a nuisance to neighbours.
• Are you sure that there are no obstacles near
the air outlet of the outdoor unit?
Such obstacles may result in declined perfor-
mance and increased running noises.
•
If abnormal noises occur in use, stop the oper-
ation of the air conditioner by remote control-
ler, consult your dealer.
Regarding drainage of drain piping
• Is the drain piping carried out properly to
ensure complete drainage?
If drain piping is not carried out properly, dirt and
debris may be accumulated in the drain pipe and
cause water leakage. If it occurs, stop the air con-
ditioner and consult with your dealer for assis-
tance.
Read the operation manual that came with
the remote controller.
•Operating procedure varies with heat pump type
and cooling only type. Contact your Daikin dealer
to confirm your system type.
•To protect the unit, turn on the main power switch
6 hours before operation.
•If the main power supply is turned off during oper-
ation, operation will restart automatically after the
power turns back on again.
5. OPERATION PROCEDURE
[CHARACTERISTICS OF THE COOLING
OPERATION (COOLING OPERATION AND
AUTOMATIC COOLING OPERATION)]
•If the COOLING OPERATION is used when the
indoor temperature is low, frost forms on the heat
exchanger of the indoor unit. This can decrease
the cooling capacity. In this case, the system
automatically switches to DEFROST OPERA-
TION for a while.
Low airflow rate is used prevent humidity increase.
•When the outdoor temperature is high, it takes
some time until the indoor temperature reaches
the set temperature.
[CHARACTERISTICS OF THE HEATING
OPERATION (HEATING OPERATION AND
AUTOMATIC HEATING OPERATION)]
START OF OPERATION
•It generally takes a longer time for HEATING
OPERATION to reach the set temperature com-
pared to COOLING OPERATION. It is advisable
to start operation in advance using TIMER OPER-
ATION.
Perform the following operation to prevent heat-
ing capacity decrease and discharge of cool air.
AT THE START OF OPERATION AND AFTER
DEFROSTING OPERATION
•A warm air circulating system is employed, and
therefore it takes some time until the entire room
is warmed up after the start of operation.
•The indoor fan runs to discharge a gentle wind
automatically until the temperature inside the air
conditioner reaches a certain level. At this time,
the remote controller displays “ ”. Leave it
as it stands and wait for a while.
•The remote controller displays the airflow rate
that is set.
DEFROST OPERATION (Frost removal oper-
ation for the outdoor unit)
•As the frost on the coil of an outdoor unit increase,
heating effect decreases and the system goes
into DEFROST OPERATION.
•The indoor unit fan stops and the remote control-
ler display shows “ ”.
The remote controller displays the airflow rate
that is set.
•After 6 to 8 minutes (maximum 10 minutes) of
DEFROST OPERATION, the system returns to
HEATING OPERATION.
6. OPERATION
CHARACTERISTICS
3PEN486799-2.book Page 7 Tuesday, June 27, 2017 10:53 AM

English 8
•When the operation is switched to the HEATING
OPERATION during or after the DEFROST
OPERATION, white mist comes out from the air
outlet of the outdoor unit.
(Refer to “VI.” on page 14.)
•A hissing and “Shuh” sound may be heard during
this particular operation.
Regarding outside air temperature and heat-
ing capacity
•The heating capacity of the air conditioner
declines as the outside air temperature falls. In
such a case, use the air conditioner in combina-
tion with other heating systems.
NOTE
•When a combustion appliance is used, ventilate
the room regularly.
•
Do not use the combustion appliance where the air
from the air conditioner is blown directly toward it.
•When the warm air stays under the ceiling and
your feet are cold, we recommend that you use a
circulator (a fan to circulate the air inside the
room). For details, consult your dealer.
•When the indoor temperature exceeds the set
temperature, the air conditioner discharges a
gentle breeze (switches to whisper mode). (The
remote controller displays the airflow rate that are
being set.)
[CHARACTERISTICS OF THE PROGRAM
DRY OPERATION]
•This operation lowers the humidity without lower-
ing the indoor temperature, and automatically
sets the airflow rate and temperature. Therefore,
the remote controller does not display the airflow
rate and set temperature. (The indoor tempera-
ture detected when the operation button is
pressed is the set temperature.)
When the indoor temperature is lowered, air dis-
charge from the air conditioner may stop.
•If the PROGRAM DRY OPERATION is used
when the indoor temperature is low, frost forms on
the heat exchanger of the indoor unit. In this case,
the system automatically switches to DEFROST
OPERATION for a while.
NOTE
•If the temperature is excessively lowered, switch
to the COOLING OPERATION once, and then
stop the operation. When the temperature
increases to a suitable level, start the PROGRAM
DRY OPERATION again.
Note: The PROGRAM DRY OPERATION cannot
be used when the indoor temperature is
20°C or lower.
[SOUND PRESSURE LEVEL]
•Sound pressure level is less than 70 dB(A).
AIRFLOW DIRECTION ADJUST
There are 2 ways of adjusting the airflow direction.
A.Left and right direction
(Horizontal airflow direction)
Press the AIRFLOW DIRECTION ADJUST
button to select the air direction as follow-
ing.
The AIRFLOW DIRECTION dis-
play swings as shown the left
and the airflow direction continu-
ously varies. (Automatic swing

Movement of left and right airflow flaps
•For the following conditions, micro computer con-
trols the airflow direction so it may be different
from the display.
•When the indoor temperature is higher than the
set temperature (HEATING OPERATION).
(The air is discharged from the centre.)
•During the DEFROST OPERATION when the
HEATING OPERATION starts (HEATING
OPERATION). (The air is discharged from the
centre.)
B.Up and down direction
(Vertical airflow direction)
The up and down airflow direction can be fixed at
the desired position manually.
HOW TO ADJUSTING UP AND DOWN AIR-
FLOW
The horizontal flaps at the air outlet are composed of
upper flaps, interlocking flaps (No.1 and No.2
groups), and lower flaps.
Adjust the flaps vertically by hand. It is effective
when the flaps are facing slightly upward for cool air,
and slightly downward for warm air.
In addition, the flaps are separated into No.1 and
No.2 groups, and this enables up and down airflow.
This is effective for controlling the indoor tempera-
ture near the air conditioner.

Group No.
The group No. is stamped on the top and back
of each flap.
NOTE
•Operating the unit with overlapping upper, lower,
and interlocking flaps and the air outlet closed
may cause dripping of condensation. Be sure not
to close off the air outlet by blocking it with the
upper, lower, or interlocking flaps.
•Do not set the horizontal flaps too far downward.
This may cause an operation failure as the air
from the air outlet is sucked from the suction grille.

Observe the following precautions to ensure the
system operates.
•Prevent direct sunlight from entering a room
during COOLING OPERATION by using curtains
or blinds.
•Keep doors and windows closed. If the doors and
windows remain open, room air will flow out and
decrease the effect of cooling and heating .
•Never place objects near the air inlet and the air
outlet of the unit. It may deteriorate the effect or
stop the operation.
•Adjust the room temperature properly for a com-
fortable environment. Avoid excessive heating or
cooling.
Not doing so wastes electricity.
•When the display shows “ ” or “Time to clean
filter”, ask a qualified service person to clean the
filters.
(Refer to “MAINTENANCE” on page 10.)
Operating the unit with stained air filter may
decrease capacity or cause malfunction.

amount of power is consumed even if the system
is not in operation. (*1) Turn off the power circuit
breaker for saving energy. When reoperating, turn
on the power circuit breaker 6 hours before
operation for smooth running. (Refer to
“MAINTENANCE” on page 10.) (*2)
*1 The consumed power while the outdoor unit is
not in operation depends on the model.
*2 The setting before the power circuit breaker is
cut off is stored. (The timer setting is cleared.)
•Fully use the function of airflow direction adjust.
Cold air gathers on the floor, and warm air gathers
in the ceiling.
Set the air discharge to horizontal direction during
COOLING or PROGRAM DRY OPERATION, and
set it downwards during HEATING OPERATION.
Do not let the air blow directly to a person.
•Use the TIMER OPERATION effectively.
It takes some time until the indoor temperature
reaches the set temperature. It is advisable to
start operation in advance using TIMER OPERA-
TION.

vate the unit smoothly.
•The display on the remote controller will be shown
when the power circuit breaker is turned on.
HEATING OPERATION within 6 hours after the
power is supplied to the power circuit breaker.
•Some models perform the following operation to
protect the devices.
If the HEATING OPERATION is performed within
6 hours after the power is supplied to the power
circuit breaker, the indoor fan stops for about 10
minutes during the outdoor unit operation to pro-
tect the devices.
The above operation is performed not only at the
time of installation, but every time the power cir-
cuit breaker is turned on/off.
WHAT TO DO TO STOP THE SYSTEM FOR A
LONG PERIOD
Turn on FAN OPERATION for a half day and dry
the unit.
•This will prevent generation of mould.
Turn off the power circuit breaker (only for
R410A refrigerant).
•
When the power circuit breaker is turned on, low
wattage is consumed even if the system is not
operating.
Turn off the power circuit breaker for saving energy.
•The display on the remote controller will vanish
when the power circuit breaker is turned off.
Clean the air filter and exterior.
•Be sure to replace the air filter to its original place
after cleaning.
Refer to “MAINTENANCE” on page 10.
This unit is equipped with a refrigerant leak detector
for safety. To be effective, the unit must be
electrically powered at all times after installation,
other than short service intervals (only for R32
refrigerant).
The following symptoms do not indicate air condi-
tioner malfunction
• HEATING OPERATION within 6 hours after the
power is supplied to the power circuit breaker.
Some models perform the following operation to
protect the devices.
If the HEATING OPERATION is performed within 6
hours after the power is supplied to the power cir-
cuit breaker, the indoor fan stops for about 10 min-
utes during the outdoor unit operation to protect
the devices.
The above operation is performed not only at the
time of installation, but every time the power cir-
cuit breaker is turned on/off.
For comfort heating, it is recommended not to turn
off the power circuit breaker during HEATING
OPERATION.
I. THE SYSTEM DOES NOT OPERATE
• The system does not restart immediately
after the ON/OFF button is pressed.
• The system does not restart immediately
when TEMPERATURE SETTING button is
returned to the former position after pushing
the button.
If the OPERATION lamp lights, the system is in
normal condition.
It does not restart immediately because a safety
device operates to prevent overload of the sys-
tem. After approx. 3 minutes, the system will turn
on again automatically.
• The system does not start when the display
shows “ ” and it flashes for few sec-
onds after pressing an operation button.
This is because the system is under centralized
control. Flashes on the display indicates that the
system cannot be controlled by the remote con-
troller.
9. NOT A MALFUNCTION OF THE
AIR CONDITIONER
3PEN486799-2.book Page 12 Tuesday, June 27, 2017 10:53 AM

13 English
• HEATING OPERATION within 6 hours after
the power is supplied to the air conditioner.
Some models perform the following operation to
protect the devices.
If the HEATING OPERATION is performed
within 6 hours after the power is supplied to the
air conditioner, the indoor fan stops for about 10
minutes during the outdoor unit operation to pro-
tect the devices.
The above operation is performed not only at the
time of installation, but every time the power cir-
cuit breaker is turned off/on.
• The outdoor unit stops.
This is because the indoor temperature has
reached the set temperature. The indoor unit is
in the FAN OPERATION.
COOLING OPERATION (AUTOMATIC COOL-
ING OPERATION): Lower the set temperature.
HEATING OPERATION (AUTOMATIC HEAT-
ING OPERATION): Raise the set temperature.
The operation starts after a while when the sys-
tem is in normal condition.
• The remote controller displays “ ”, and
air discharge stops.
This is because the system automatically
switches to DEFROST OPERATION to prevent
a decrease in heating capacity when frost on the
outdoor unit increases.
After 6 to 8 minutes (maximum 10 minutes), the
system returns to its original operation.
II. THE OPERATION SOMETIMES STOPS.
• The remote controller displays “U4” and
“U5”, and the operation stops. However, it
will restart in a few minutes.
This is because communication between the
units is shut off and stops the operation due to
noise caused by devices other than the air con-
ditioner.
When the electrical noise decreases, the system
automatically restarts.
III. THE FAN SPEED IS DIFFERENT FROM THE
SETTING.
• Even if the fan speed control button is
pressed, the fan speed does not change.
During the COOLING OPERATION, the airflow
rate is lowered to prevent the carryover of
melted water. In addition, during DEFROST
OPERATION (in the HEATING OPERATION),
the unit stops discharging air so it does not blow
directly toward your body.
After a while, the airflow rate can be changed.
(The airflow rate cannot be set for the PRO-
GRAM DRY OPERATION.)
When the room temperature exceeds the set
temperature the indoor unit goes into whisper
mode. It takes some time until the airflow rate
changes.
Raise the set temperature. After a while, the air-
flow rate changes.
IV.
AIR BLOW DIRECTION IS NOT AS SPECIFIED.
• Actual air blow direction is not as shown on
the remote controller.
• Automatic swing setting does not work.
This is because the airflow rate is automatically
controlled.
After a while, the airflow direction can be
changed.
V. THE AIRFLOW DIRECTION DIFFERS FROM
THE REMOTE CONTROLLER DISPLAY.
• The airflow flaps do not swing when the
remote controller displays the swing opera-
tion.
<HEATING OPERATION>
This is because the airflow direction from the
centre air outlet is controlled when the indoor
temperature is higher than the set temperature.
After a while, the swing operation starts.
(Refer to “Movement of left and right airflow
flaps” on page 9.)
• The airflow direction display of the remote
controller differs from the actual operation of
the airflow flaps.
<HEATING OPERATION>
This is because the airflow direction from the
centre air outlet is controlled immediately after
the start of operation or when the indoor tem-
perature is higher than the set temperature.
After a while, the airflow direction changes to the
set direction.
(Refer to “Movement of left and right airflow
flaps” on page 9.)

VI. WHITE MIST COMES OUT OF A UNIT
• When humidity is high during COOLING
OPERATION (In oily or dusty places)
If the inside of an indoor unit is extremely con-
taminated, the temperature distribution inside a
room becomes uneven. It is necessary to clean
the inside of the indoor unit. Ask your Daikin
dealer for details on cleaning the unit. This oper-
ation requires a qualified service person.
Check the usage environment.
• When the operation is switched to the HEAT-
ING OPERATION during or after the DEFROST
OPERATION.
Moisture generated by DEFROST becomes
steam and will float around.
When the remote controller display shows
“ ”, the unit is in DEFROST OPERATION.
VII.NOISE OF AIR CONDITIONERS
• A ringing sound after the unit starts.
This sound is generated when the motors for
driving the airflow flaps are working.
It will quiet down after about a minute.
• A continuous flow “Shuh” sound is heard
when the systems is in COOLING or
DEFROST OPERATION.
This is the sound of refrigerant gas flowing
through both indoor and outdoor units.
• A “Shuh” sound which is heard at the start or
immediately after the stop of operation or
which is heard at the start or immediately
after the stop of DEFROST OPERATION.
This is the noise of refrigerant caused by flow
stop and flow change.
During HEATING OPERATION, the system
switches to DEFROST OPERATION automati-
cally. The remote controller shows “ ”.
After 6 to 8 minutes (maximum 10 minutes), the
system returns to its original operation.
• A continuous flow “Shah” sound is heard
when the system is in COOLING OPERATION
or at a stop.
The noise is heard when the drain pump is in
operation.
Moisture removed from the indoor air during the
COOLING OPERATION is drained. (The drain-
ing device is provided as an optional part.)
• A “Pishi-pishi” squeaking sound is heard
when the system is in operation or after the
stop of operation.
Expansion and contraction of plastic parts
caused by temperature change makes this
noise.
VIII.DUST FROM THE UNITS
• Dust may blow out from the unit after starting
operation from long resting time.
Dust absorbed by the unit blows out.
IX. THE UNITS GIVE OFF ODORS
• During operation
The unit absorbs the smell of rooms, furniture,
cigarettes, etc., and then emits them.
If odor is a concern, you can set to zero airflow
rate when the indoor temperature reaches the
set temperature.
For details, contact your Daikin dealer.
X. THE UNIT DOES NOT COOL EFFECTIVELY.
• The unit is operating in program dry mode.
This is because program dry mode operates so
that the indoor temperature decreases as little
as possible.
Lower the indoor temperature using COOLING
OPERATION, and then use PROGRAM DRY
OPERATION.
(Refer to “CHARACTERISTICS OF THE PRO-
GRAM DRY OPERATION” on page 8.)
•Read through characteristics of the COOLING
OPERATION, characteristics of the HEATING
OPERATION, and characteristics of the PRO-
GRAM DRY OPERATION on page 7, 8.
This unit is equipped with a refrigerant leak detector
for safety. To be effective, the unit must be
electrically powered at all times after installation,
other than short service intervals (only for R32
refrigerant).
Please check before requesting a service call.
1. If the system does not operate at all.
•Check if fuse has blown.
Turn off the power supply.
•Check if the power circuit breaker is blown.
Turn the power on with the power circuit
breaker switch in the off position.
Do not turn the power on with the power circuit
breaker switch in the trip position.
(Contact your dealer.)
•Check if there is a power failure.
Wait until power is restored. If power failure
occurs during operation, the system automati-
cally restarts immediately after the power sup-
ply recovers.

2. If the system stops operating after opera-
tion is complete.
•Check if the air inlet or outlet of outdoor or
indoor unit is blocked by obstacles.
Remove the obstacle and make it well-venti-
lated.
•Check if the air filter is clogged.
Ask a qualified service person to clean the air
filters.
(Refer to “MAINTENANCE” on page 10.)
If the air filter is clogged, the airflow rate will
drop and as a result the performance will also
drop.
In addition, this may cause dew condensation
at the air outlet.
(Refer to “MAINTENANCE” on page 10.)
3. The system operates but it does not suf-
ficiently cool or heat.
•If the air inlet or outlet of the indoor or the out-
door unit is blocked with obstacles.
Remove the obstacle and make it well-venti-
lated.
Obstacles decrease the airflow rate, and
cause performance decrease and breakage
when discharged air is suctioned.
They cause a waste of electricity, and that may
stop the devices.
•If the air filter is clogged.
Ask a qualified service person to clean the air
filters.
(Refer to “MAINTENANCE” on page 10.)
A decrease in the airflow volume of the air con-
ditioner will result and the performance of the
air conditioner will be degraded if the air filter is
clogged with dust or dirt.
In addition, this may cause dew condensation
at the air outlet.
(Refer to “MAINTENANCE” page 10.)
•If the set temperature is not proper (Set to an
appropriate temperature, airflow rate, and dis-
charge direction.).
•If the FAN SPEED button is set to LOW
SPEED (Set to an appropriate temperature,
airflow rate, and discharge direction.).
•If the airflow angle is not proper.
(Refer to “AIRFLOW DIRECTION ADJUST” on
page 8.)
•
If the doors or the windows are open. Shut doors
or windows to prevent wind from coming in.
• If direct sunlight enters the room (when cooling).
Use curtains or blinds.
•When there are too many inhabitants in the
room (when cooling).
•If the heat source of the room is excessive
(when cooling).
4. Though the on/off button was not
pressed, the unit started or stopped.
•Are you sure that the ON/OFF timer operation
is not used?
Turn off the ON/OFF timer.
•Are you sure that a remote control device is not
connected?

points, please do not try to repair it yourself. In such
cases, always ask your local dealer. At this time,
please tell the symptom and model name (written on
the model name plate).
5. The unit is operating by itself.
• The fan is spinning by itself, when the unit is
turned off. (The operation light is flashing)
It is because the refrigerant leakage sensor
started working.
•There is a risk of refrigerant leakage. Please
ventilate the room and contact your dealer.
•If there is no leak, the fan will turn itself off auto-
matically in a few minutes.
Sometimes, the refrigerant leakage sensor
detects by mistake substances other than
refrigerant, such as insecticides or hairsprays
(only for R32 refrigerant).
6. It does not cool / warm up.
• When in cooling or heating mode, it switches
to “Strong air flow” ventilation setting.
It is because the refrigerant leakage sensor
started working
•There is a risk of refrigerant leakage. Please
ventilate the room and contact your dealer.
•If there is no leak, it will return to the previous
mode of operation automatically after a few
minutes.
Sometimes, the refrigerant leakage sensor
detects by mistake substances other than
refrigerant, such as insecticides or hairsprays
