12 English
• A continuous flow “Shah” sound is heard
when the system is in COOLING OPERATION
or at a stop.
The noise is heard when the drain pump is in
operation.
Moisture removed from the indoor air during the
COOLING OPERATION is drained. (The drain-
ing device is provided as an optional part.)
• A “Pishi-pishi” squeaking sound is heard
when the system is in operation or after the
stop of operation.
Expansion and contraction of plastic parts
caused by temperature change makes this
noise.
VIII.DUST FROM THE UNITS
• Dust may blow out from the unit after starting
operation from long resting time.
Dust absorbed by the unit blows out.
IX. THE 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 airflow
rate when the indoor temperature reaches the
set temperature.
For details, contact your Daikin dealer.
X. THE UNIT DOES NOT COOL EFFECTIVELY.
• The unit is operating in program dry mode.
This is because program dry mode operates so
that the indoor temperature decreases as little
as possible.
Lower the indoor temperature using COOLING
OPERATION, and then use PROGRAM DRY
OPERATION.
(Refer to “CHARACTERISTICS OF THE PRO-
GRAM DRY OPERATION” on page 6.)
• Read through characteristics of the COOLING
OPERATION, characteristics of the HEATING
OPERATION, and characteristics of the PRO-
GRAM DRY OPERATION on page 5, 6.
Please check before requesting a service call.
1. If the system does not operate at all.
• Check if no fuse has blown.
Turn off the power supply.
• Check if the power circuit breaker is blown.
Turn the power on with the power circuit
breaker switch in the off position.
Do not turn the power on with the power circuit
10. TROUBLE SHOOTING
breaker switch in the trip position.
(Contact your dealer.)
• Check if there is a power failure.
Wait until power is restored. If power failure
occurs during operation, the system automati-
cally restarts immediately after the power sup-
ply recovers.
2. If the system stops operating after operation
is complete.
• 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.
• Check if the air filter is clogged.
Ask a qualified service person to clean the air
filters.
(Refer to “MAINTENANCE” on page 8.)
If the air filter is clogged, the airflow rate will
drop and as a result the performance will also
drop.
In addition, this may cause dew condensation
at the air outlet.
(Refer to “MAINTENANCE” on page 8.)
3. The system operates but it does not suffi-
ciently cool or heat.
• If the air inlet or outlet of the indoor or the out-
door unit is blocked with obstacles.
Remove the obstacle and make it well-venti-
lated.
Obstacles decrease the airflow rate, and
cause performance decrease and breakage
when discharged air is suctioned.
They cause a waste of electricity, and that may
stop the devices.
• If the air filter is clogged.
Ask a qualified service person to clean the air
filters.
(Refer to “MAINTENANCE” on page 8.)
A decrease in the airflow volume of the air con-
ditioner will result and the performance of the
air conditioner will be degraded if the air filter is
clogged with dust or dirt.
In addition, this may cause dew condensation
at the air outlet.
(Refer to “MAINTENANCE” page 8.)
• If the set temperature is not proper (Set to an
appropriate temperature, airflow rate, and dis-
charge direction.).
