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?
Contact the central control room that directed
the stop.
•
Are you sure that the display for centralized
control is not lit?
Contact the central control room that directed
the stop.
If the problem is not solved after checking the above
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
(only for R32 refrigerant).
