• HEATING OPERATION within 6 hours after
the power is supplied to the air conditioner.
Some models perform the following operation to
protect the devices.
If the HEATING OPERATION is performed
within 6 hours after the power is supplied to the
air conditioner, the indoor fan stops for about 10
minutes during the outdoor unit operation to pro-
tect the devices.
The above operation is performed not only at the
time of installation, but every time the power cir-
cuit breaker is turned off/on.
For comfortable use, do not turn off the power
circuit breaker during seasonal use of the HEAT-
ING OPERATION.
• The outdoor unit stops.
This is because the indoor temperature has
reached the set temperature. The indoor unit is
in the FAN OPERATION.
COOLING OPERATION (AUTOMATIC COOL-
ING OPERATION): Lower the set temperature.
HEATING OPERATION (AUTOMATIC HEAT-
ING OPERATION): Raise the set temperature.
The operation starts after a while when the sys-
tem is in normal condition.
• The remote controller displays “
”, and
air discharge stops.
This is because the system automatically
switches to DEFROST OPERATION to prevent
a decrease in heating capacity when frost on the
outdoor unit increases.
After 6 to 8 minutes (maximum 10 minutes), the
system returns to its original operation.
II. THE OPERATION SOMETIMES STOPS.
• The remote controller displays “U4” and
“U5”, and the operation stops. However, it
will restart in a few minutes.
This is because communication between the
units is shut off and stops the operation due to
noise caused by devices other than the air con-
ditioner.
When the electrical noise decreases, the system
automatically restarts.
III. THE FAN SPEED IS DIFFERENT FROM THE
SETTING.
• Even if the fan speed control button is
pressed, the fan speed does not change.
For the DEFROST OPERATION during the
COOLING OPERATION, the airflow rate is low-
ered to prevent the carryover of melted water.
After a while, the airflow rate can be changed.
(The airflow rate cannot be set for the PRO-
GRAM DRY OPERATION.)
When the room temperature exceeds the set
temperature the indoor unit goes into whisper
mode. It takes some time until the airflow rate
changes.
Raise the set temperature. After a while, the air-
flow rate changes.
IV. AIR BLOW DIRECTION IS NOT AS SPECI-
FIED.
• Actual air blow direction is not as shown on
the remote controller.
• Automatic swing setting does not work.
This is because the airflow rate is automatically
controlled.
After a while, the airflow direction can be
changed.
V. THE AIRFLOW DIRECTION DIFFERS FROM
THE REMOTE CONTROLLER DISPLAY.
• The airflow flaps do not swing when the
remote controller displays the swing opera-
tion.
<HEATING OPERATION>
This is because the airflow direction is controlled
so it is horizontal right after the operation starts
or when the indoor temperature is higher than
the set temperature to prevent air from blowing
directly toward your body.
After a while, the swing operation starts.
(Refer to “MOVEMENT OF THE AIRFLOW
FLAP” on page 8.)
• The airflow direction display of the remote
controller differs from the actual operation of
the airflow flaps.
<COOLING and PROGRAM DRY OPERA-
TIONS>
When the operation in a downward airflow direc-
tion is set, the airflow direction differs from the
display for a period of time to prevent the flaps
from getting frosted.
After a while, the airflow direction changes to the
set direction.
(Refer to “MOVEMENT OF THE AIRFLOW
FLAP” on page 8.)
<HEATING OPERATION>
This is because the airflow direction is controlled
so it is horizontal right after the operation starts
or when the indoor temperature is higher than
the set temperature to prevent air from blowing
directly toward your body.
After a while, the airflow direction changes to the
set direction.
