CHARACTERISTICS OF THE
COOLING OPERATION (COOLING
OPERATION AND AUTOMATIC
COOLING OPERATION)
CHARACTERISTICS OF THE
HEATING OPERATION (HEATING
OPERATION AND AUTOMATIC
HEATING OPERATION)
• After continuous operation with the airflow
horizontally or downward, the air
conditioner operates with different airflow
direction for a certain period of time to
prevent condensation build-up on the
airflow direction blades. (The remote
controller displays the airflow direction
that is set.)
• If the COOLING OPERATION is used
when the indoor temperature is low, frost
adheres to the heat exchanger of the indoor
unit. This can decrease the cooling capacity.
In this case, the system automatically
switches to DEFROST OPERATION for
a while.
During DEFROST OPERATION, the low
fan speed is used to prevent the discharge
of melt water. (The remote controller
displays the fan speed that is set.)
• When the outside temperature is high, it
takes some time until the indoor
temperature reaches the set temperature.
START OF OPERATION
After operation is stopped
• It generally takes a longer time for indoor
temperature of the HEATING OPERATION
to reach the set temperature compared to
the COOLING OPERATION. It is advisable
to start operation in advance using the
TIMER OPERATION.
• The fan operates for about 1 minute to
dispel heat inside the indoor unit.
Perform the following operation to prevent
heating capacity decrease and discharge
of cool air.
AT THE START OF OPERATION AND
AFTER DEFROST 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 DEFROST
OPERATION LAMP on the light receiving
unit indicator lights. Leave it as it stands
and wait for a while.
(The remote controller displays the fan
speed that is set.)
• The air discharge direction becomes
horizontal to prevent a draft of cool air to
the inhabitants. (The remote controller will
display the set airflow direction.)
DEFROST OPERATION (Frost removal
operation for the outdoor unit)
• As the frost on the coil of an outdoor unit
increase, heating effect decreases and the
system goes into the DEFROST
OPERATION.
• The warm air stops, and the DEFROST
OPERATION LAMP on the light receiving
unit turn on. (The remote controller displays
the fan speed that is set.)
• After maximum 10 minutes of the
DEFROST OPERATION, the air conditioner
returns to the HEATING OPERATION.
• The airflow direction becomes horizontal.
(The remote controller displays the airflow
direction that is set.)
• During or after the DEFROST OPERATION,
white mist comes out from the air inlet or
outlet of the air conditioner.
• A hissing and “Shuh” sound may be heard
during this particular operation.
Regarding outside air temperature
and heating capacity
• The heating capacity of the air conditioner
declines as the outside air temperature falls.
In such a case, use the air conditioner in
combination with other heating systems.
(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.

10
FAN OPERATION
• 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 local dealer.
• When the indoor 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 fan
speed and airflow direction that are set.)
• Only the fan inside the indoor unit
operates, and the air in the room is
circulated.
CHARACTERISTICS OF THE
PROGRAM DRY OPERATION
• This operation lowers the humidity without
lowering the indoor temperature. The indoor
temperature when the operation button is
pressed will be the set temperature. At this
time, the fan speed and temperature are
set automatically, so the remote controller
does not display the fan speed and set
temperature.
To efficiently lower the indoor temperature
and humidity, first use the COOLING
OPERATION to lower the indoor
temperature, and then use the PROGRAM
DRY OPERATION. When the indoor
temperature is lowered, airflow from the
indoor unit may stop.
• When operating continuously at downward
airflow direction, air blows in the auto-
matically set direction for a period of time
to prevent condensation on the horizontal
blades.
• 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 the DEFROST
OPERATION for a while.
