IX. THE INDOOR UNITS GIVE OFF ODORS
• During operation
The unit absorbs the smell of rooms, furni-
ture, cigarettes, etc., and then emits them.
If odor is a concern, set the fan speed to no
airflow when the indoor temperature reaches
the set temperature.
For details, contact your local dealer.
X. THE AIR CONDITIONER DOES NOT COOL
EFFECTIVELY
• The air conditioner is operating in PRO-
GRAM 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 7.)
• Read through characteristics of the
COOLING OPERATION, characteristics of
the HEATING OPERATION, and character-
istics of the PROGRAM DRY OPERATION
on page 6-7.
9-2. FXUQ
Read the operation manual attached to the out-
door unit.
10-1. FUQ
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
occurs during operation, the air conditioner
automatically 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-venti-
lated.
The horizontal blades at the air outlet are closed
while the indoor stops.
•
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
conditioner will result and the performance of
the air conditioner will be degraded and power
consumption 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 9.)
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-venti-
lated.
The horizontal blades at the air outlet are
closed while the indoor unit stops.
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
conditioner will result and the performance of
the air conditioner will be degraded and power
consumption 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 9.)
•
Check if the set temperature is not proper.
Set to an appropriate temperature, fan speed,
and airflow direction.
•
Check if the FAN SPEED button is set to LOW
SPEED.
Set to an appropriate temperature, fan speed,
and airflow direction.
