English 6
• If the main power supply is turned off during
operation, operation will restart automatically
after the power turns back on again.
6. OPERATION CHARACTERISTICS
 CHARACTERISTICS OF THE COOLING
OPERATION (COOLING OPERATION AND
AUTOMATIC COOLING OPERATION)
• 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 air conditioner automatically
switches to the DEFROST OPERATION for a
while.
During the DEFROST OPERATION, the low fan
speed or a gentle wind is used to prevent the
discharge of melt water.
(The remote controller displays the fan speed that
is set.)
• 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 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.
Perform the following operation to prevent
heating capacity decrease and discharge of cool
air.
AT THE START OF OPERATION AND AFTER
THE 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 remote controller displays "
". Leave it
as it stands and wait for a while.
(The remote controller displays the fan speed that
is set.)
• The airflow direction becomes horizontal to
prevent a draft of cool air to the inhabitants. (The
remote controller displays the set airflow direction
that is set.)
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 air conditioner
goes into the DEFROST OPERATION.
• The indoor unit fan stops and the remote
controller display shows "
".
With the wireless remote controller, 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.
(Refer to "
WHITE MIST COMES OUT OF THE
AIR CONDITIONER " on page 13.)
• 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.)
