„CHARACTERISTICS OF THE HEATING
OPERATION (HEATING OPERATION AND
AUTOMATIC HEATING OPERATION)
START OF OPERATION
• 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.
After operation is stopped
• 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.
• 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.)
FAN OPERATION
• Only the fan inside the indoor unit operates,
and the air in the room is circulated.
„CHARACTERISTICS OF THE 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 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 automatically
set direction for a period of time to prevent
condensation on the horizontal blades.
• If the 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.
