VI. WHITE MIST COMES OUT OF A UNIT
• When humidity is high during COOLING
OPERATION (In oily or dusty places)
If the inside of an indoor unit is extremely con-
taminated, the temperature distribution inside a
room becomes uneven. It is necessary to clean
the inside of the indoor unit. Ask your Daikin
dealer for details on cleaning the unit. This oper-
ation requires a qualified service person.
Check the usage environment.
• When the operation is switched to the HEAT-
ING OPERATION during or after the DEFROST
OPERATION.
Moisture generated by DEFROST becomes
steam and will float around.
When the remote controller display shows
“
”, the unit is in DEFROST OPERATION.
VII.NOISE OF AIR CONDITIONERS
• A ringing sound after the unit starts.
This sound is generated when the motors for
driving the airflow flaps are working.
It will quiet down after about a minute.
• A continuous flow “Shuh” sound is heard
when the systems is in COOLING or
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 DEFROST OPERATION.
This is the noise of refrigerant caused by flow
stop and flow change.
During HEATING OPERATION, the system
switches to DEFROST OPERATION automati-
cally. The remote controller shows “
”.
After 6 to 8 minutes (maximum 10 minutes), the
system returns to its original operation.
• 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 8.)
•
Read through characteristics of the COOLING
OPERATION, characteristics of the HEATING
OPERATION, and characteristics of the PRO-
GRAM DRY OPERATION on page 7, 8.
This unit is equipped with a refrigerant leak detector
for safety. To be effective, the unit must be
electrically powered at all times after installation,
other than short service intervals (only for R32
refrigerant).
Please check before requesting a service call.
1. If the system does not operate at all.
•
Check if 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
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.
