Perform the following operation to pre-
vent heating capacity decrease and dis-
charge 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 OPERA-
TION LAMP for the light receiving unit indi-
cator lights. 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 hori-
zontal to prevent a draft of cool air to the
inhabitants (The remote controller will dis-
play the set air discharge 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 DEFROST OPERA-
TION.
• 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 min-
utes) of DEFROST OPERATION, the sys-
tem returns to HEATING OPERATION.
• The air discharge direction becomes hori-
zontal. (The remote controller displays the
airflow direction 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.
• 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 dealer.
• When the indoor temperature exceeds the
set temperature, the air conditioner dis-
charges a gentle breeze (switches to whis-
per mode). The air discharge direction
becomes horizontal. (The remote control-
ler displays the airflow rate and airflow
direction that are being set.)
[CHARACTERISTICS OF THE PRO-
GRAM 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 tempera-
ture. At this time, the airflow rate and
humidity are set automatically, so the
remote controller does not display the air-
flow rate and set temperature.
To efficiently lower the indoor temperature
and humidity, first lower the indoor temper-
ature using the COOLING OPERATION,
and then use PROGRAM DRY OPERA-
TION. When the indoor temperature is
lowered, air discharge from the air condi-
tioner may stop.
• After continued operation at a downward
airflow direction, operate the air condi-
tioner using a different direction setting for
a period of time to prevent condensation
on the airflow flaps. (The remote controller
displays the airflow direction that is set.)
