[CHARACTERISTICS OF THE COOLING
OPERATION (COOLING OPERATION AND
AUTOMATIC COOLING OPERATION)]
• After continued operation at a downward airflow
direction, operate the air conditioner using a dif-
ferent direction setting for a period of time to pre-
vent condensation on the airflow flaps. (The
remote controller displays the airflow direction
that is set.)
• If the COOLING OPERATION is used when the
indoor temperature is low, frost forms on the heat
exchanger of the indoor unit. This can decrease
the cooling capacity. In this case, the system
automatically switches to DEFROST OPERA-
TION for a while.
During DEFROST OPERATION, the low airflow
rate is used to prevent the discharge of melt
water. (The remote controller displays the airflow
rate 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 HEATING
OPERATION to reach the set temperature com-
pared to COOLING OPERATION. It is advisable
to start operation in advance using TIMER OPER-
ATION.
Perform the following operation to prevent heat-
ing 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 remote controller displays “ ”. Leave it
as it stands and wait for a while.
(The remote controller displays the airflow rate
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 air discharge
direction.)
6. OPERATION
CHARACTERISTICS
DEFROST OPERATION (Frost removal oper-
ation for the outdoor unit)
• As the frost on the coil of an outdoor unit increase,
heating effect decreases and the system goes
into DEFROST OPERATION.
• The indoor unit fan stops and the remote control-
ler display shows “ ”.
With the wireless remote controller, the warm air
stops, and the DEFROST OPERATION lamp for
the light receiving unit indicator lights. (The
remote controller displays the airflow rate that is
set.)
• After 6 to 8 minutes (maximum 10 minutes) of
DEFROST OPERATION, the system returns to
HEATING OPERATION.
• The air discharge direction becomes horizontal.
(The remote controller displays the airflow direc-
tion that is set.)
• When the operation is switched to the HEATING
OPERATION during or after the DEFROST
OPERATION, white mist comes out from the air
outlet of the outdoor unit.
(Refer to “VII.” on page 12.)
• A hissing and “Shuh” sound may be heard during
this particular operation.
Regarding outside air temperature and heat-
ing capacity
• The heating capacity of the air conditioner
declines as the outside air temperature falls. In
such a case, use the air conditioner in combina-
tion 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 dealer.
• When the indoor temperature exceeds the set
temperature, the air conditioner discharges a
gentle breeze (switches to whisper mode). The air
discharge direction becomes horizontal. (The
remote controller displays the airflow rate and air-
flow direction that are being set.)
