Characteristic of Cooling operation (in Cool/Auto mode)
• When operating continuously at horizontally or downward airflow
direction, air blows in the automatically set direction for a period of time
to prevent condensation on the horizontal flap.
(The remote controller displays the airflow direction that is set.)
• If the Cooling operation is used when the room temperature is low, frost
forms on the heat exchanger of the indoor unit.
This can decrease the cooling capacity. In this case, the air conditioner
automatically switches to the Defrost operation for a while.
During the Defrost operation, the low airflow rate or a gentle wind is
used to prevent the discharge of melt water.
(The remote controller displays the airflow rate that is set.)
• When the outdoor air temperature is high, it takes some time until the
room temperature reaches the set temperature.
Characteristic of Heating operation (in Heat/Auto mode)
Starting operation
• Heating operation generally requires a longer time to reach the set
temperature compared with Cooling operation.
It is recommended to start operating in advance by utilizing the timer.
The air conditioner automatically controls the following operation to
prevent the reduction of heating capacity and space comfort.
Defrost operation
(Frost removal
operation for the
outdoor unit)
• The air conditioner will automatically go into Defrost operation to
prevent frost accumulation at the outdoor unit and loss of heating
capacity.
• The indoor unit fan will stop, and “
” (Defrost/Hot start) will be
displayed on the remote controller.
• The air conditioner will return to normal operation after approximately
6 to 8 minutes (Max 10 minutes).
Hot start
• When the air conditioner goes into Heating operation or Defrost
operation, the indoor unit fan will stop in order to prevent a cold draft.
(In that case, “
” (Defrost/Hot start) will be displayed on the
remote controller.)
Regarding outdoor
air temperature and
heating capacity
• The heating capacity will drop with a decrease in outdoor air temperature.
If the heating effect is insufficient, it is recommended to use another
heating appliance in combination with the air conditioner.
(When a combustion appliance is used, ventilate the room regularly.)
Do not use the combustion appliance in places where the combustion
appliance is exposed to the wind from the air conditioner.
• This air conditioner is a hot air circulation type to warm the whole room.
Therefore, it takes some time for the room to become warm after the
system starts operating.
When the room temperature exceeds the set temperature, the indoor
unit discharges a gentle breeze (switches to gentle wind). The airflow
direction becomes horizontal.
(The remote controller displays the airflow rate and airflow direction that
are set.)
• If the hot air stays around the ceiling and your feet feel cold, the use of
a circulator is recommended.
