IV. THE AIRFLOW DIRECTION IS DIFFERENT
FROM THE SETTING, OR THE AIRFLOW
DIRECTION IS DIFFERENT FROM THE DIS-
PLAY ON THE REMOTE CONTROLLER
• The horizontal blades do not swing when
the remote controller displays the swing
operation.
<HEATING OPERATION>
This is because the airflow direction is con-
trolled so it is horizontal direction after the
operation starts or when the indoor tempera-
ture is higher than the set temperature to pre-
vent air discharge directly toward your body.
After a while, the swing operation starts.
(Refer to
“MOVEMENT OF THE HORI-
ZONTAL BLADE”
on page 8.)
• The airflow direction display of the
remote controller differs from the actual
operation of the horizontal blades.
<COOLING and PROGRAM DRY OPERA-
TIONS>
When the operation in a downward airflow
direction is set, the airflow direction differs
from the display for a period of time to pre-
vent condensation on the horizontal blades.
<HEATING OPERATION>
This is because the airflow direction is con-
trolled so it is horizontal direction after the
operation starts or when the indoor temper-
ature is higher than the set temperature to
prevent air discharge directly toward your
body.
After a while, the airflow direction changes
to the set direction.
(Refer to
“MOVEMENT OF THE HORI-
ZONTAL BLADE”
page 8.)
V. HORIZONTAL BLADES DO NOT CLOSE
• The horizontal blades do not close even
when operation stops.
This is because the horizontal blades close
once airflow from the air conditioner stops.
After a while, the horizontal blades close.
VI. WHITE MIST COMES OUT OF THE AIR CON-
DITIONER
• When humidity is high during the COOL-
ING OPERATION. (In oily or dusty places)
If the inside of an indoor unit is extremely
contaminated, the temperature distribution
inside a room becomes uneven.
It is necessary to clean the inside of the
indoor unit.
Ask your local dealer for details on cleaning
the indoor unit.
This cleaning requires a qualified service
person.
Check the usage environment.
• When the air conditioner is changed over
to the HEATING OPERATION after the
DEFROST OPERATION and in the
DEFROST OPERATION.
Moisture generated by defrost becomes
steam and exists.
When the remote controller display shows
“
”, DEFROST OPERATION is being
used.
VII. NOISE OF AIR CONDITIONERS
• A ringing sound after the indoor unit is
started.
This sound is generated when the motors for
driving the horizontal blades are working.
It will quiet down after about a minute.
• A low continuous flow “Shuh” sound
which is heard when the air conditioner is
in the COOLING or DEFROST OPERA-
TION or a trickling sound which is heard
when the air conditioner is in the
DEFROST OPERATION.
This is the sound of refrigerant gas flowing
through both indoor and outdoor units.
• A “Shuh” sound which is heard at the
start or immediately after the stop of
operation or which is heard at the start or
immediately after the stop of the
DEFROST OPERATION.
This is the noise of refrigerant caused by flow
stop and flow change.
During the HEATING OPERATION, the air
conditioner switches to the DEFROST
OPERATION automatically.
The remote controller shows “
”.
After maximum 10 minutes, the air condi-
tioner returns to its original operation.
• A continuous flow “Shah” sound is heard
when the air conditioner is in the COOL-
ING OPERATION or at a stop.
The noise is heard when the drain pump is in
operation.
Liquid removed from the indoor air during the
COOLING OPERATION is discharged.
• A “Pishi-pishi” squeaking sound is heard
when the air conditioner is in operation or
after the stop of operation.
Expansion and contraction of resin parts
caused by temperature change makes this
noise.
VIII. DUST FROM THE INDOOR UNITS
• Dust may blow out from the unit after
starting operation from long resting time.
Dust absorbed by the unit blows out.
