VI. 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.
VII. THE INDOOR UNITS GIVE OFF ODORS
•
During operation
The unit absorbs the smell of rooms,
furniture, cigarettes, etc., and then emits
them.
If odor is a concern, you can set to zero fan
speed when the indoor temperature reaches
the set temperature.
For details, contact your local dealer.
VIII. THE AIR CONDITIONER DOES NOT COOL
EFFECTIVELY
•
The air conditioner is operating in the
PROGRAM DRY OPERATION.
This is because program dry mode operates
so that the indoor temperature decreases as
little as possible.
Lower the indoor temperature using the
COOLING OPERATION, and then use the
PROGRAM DRY OPERATION.
(Refer to
CHARACTERISTICS OF THE
PROGRAM DRY OPERATION
on page 6.)
•
Read through characteristics of the
COOLING OPERATION, characteristics of
the HEATING OPERATION, and charac-
teristics of the PROGRAM DRY OPERA-
TION on page 6-7.
10. TROUBLESHOOTING
Please check before requesting a service.
1. If the air conditioner does not operate at all.
•
Check if fuse has blown.
Turn off the power supply.
•
Check if the power circuit breaker is blown.
If the tab of power circuit breaker is in the OFF
position, turn the power on with the power cir-
cuit breaker switch.
If the tab of power circuit breaker is in the trip
position do not turn the power on with the
power circuit breaker switch.
Contact your local dealer.

•
Check if there is a power failure.
Wait until power is restored. If power failure oc-
curs during operation, the air conditioner auto-
matically restarts immediately after the power
supply recovers.
2. If the air conditioner stops after operating the
air conditioner.
•
Check if the air inlet or outlet of outdoor or
indoor unit is blocked by obstacles.
Remove the obstacle and make it well-
ventilated.
•
Check if the air filter is clogged.
Ask a qualified service person to clean the air
filters.
A decrease in the airflow volume of the air con
-
ditioner will result and the performance of the
air conditioner will be degraded and power con-
sumption will increase if the air filter is clogged
with dust or dirt.
In addition, this may cause dew condensation
at the air outlet.
(Refer to
8. MAINTENANCE
on page 7.)
3. The air conditioner operates but it does not
sufficiently cool or heat.
•
Check if the air inlet or outlet of outdoor or
indoor unit is blocked by obstacles.
Remove the obstacle and make it well-ventilat-
ed.
Obstacles decrease the fan speed, and cause
performance decrease and breakage when
discharged air is suctioned.
They cause a waste of electricity, and that may
stop the devices.
•
Check if the air filter is clogged.
Ask a qualified service person to clean the air
filters.
A decrease in the airflow volume of the air con
-
ditioner will result and the performance of the
air conditioner will be degraded and power con-
sumption will increase if the air filter is clogged
with dust or dirt.
In addition, this may cause dew condensation
at the air outlet.
(Refer to
8. MAINTENANCE
on page 7.)
•
Check if the set temperature is not proper.
Set to an appropriate temperature and fan
speed.
•
Check if the FAN SPEED button is set to LOW
SPEED.
Set to an appropriate temperature and fan
speed.
•
Check if the doors or the windows are open.
Shut doors or windows to prevent wind from
coming in.
