Noise is heard. • During the operation or immediately after stopping the air conditioner, refrigerant flowing sound
may be heard. And it is particularly noticeable for 2–3 minutes after starting operation.
• During the operation, a slight squeaking sound produced by the minute expansion and contraction –
of the front panel caused by temperature change may be heard.
During heating operation, a sizzling sound produced by the automatic defrosting operation may be
6
heard.
Smell coming from the unit. Various room smells generated from interior textile, furniture, or cigarette smoke absorbed into the air

the automatic defrosting operation may be seen.
Airflow is weak or stops. • Immediately after the heating operation is started, the fan speed stays temporarily very low to warm
up the internal parts of the unit.
• In HEAT mode, the outdoor unit stops and the indoor unit operates at very low fan speed if the –
room temperature rises above the set temperature.
In HEAT mode, the indoor unit temporarily stops for maximum of 15 minutes to perform the automatic
6
defrosting operation while the OPERATION indicator is flashing.
In DRY mode, the indoor unit operates at low fan speed to adjust the room humidity, and may stop
–
from time to time.
When the fan speed is set to “QUIET”, the fan rotates at very low speed and the airflow is reduced. –
In COOL mode, the indoor unit fan may stop from time to time when the outdoor unit is stopped. 3
When monitoring operation is performed in AUTO mode, the fan rotates at very low speed. –
When multiple units are operated in following combination of different operation modes in a multi-
type air conditioning system, the indoor unit operated afterward stops and the OPERATION indicator
flashes. 5

Before you call for or request servicing, troubleshoot a problem by performing following checks:
Symptom Diagnostic See page
Does not operate at all.  Has the circuit breaker been turned off?
 Has there been a power outage? –
 Has a fuse blown out or the circuit breaker been tripped?
 Is the timer operating? 5

mance.
 Is the intake grill or outlet port of indoor unit blocked? –
 Is the room temperature adjusted appropriately? 3
 Is a window or door left opened?
 Is direct or strong sunlight shinning into the room in cooling operation?
–
 Are there other heating apparatus or computers operating, or too many people in the room in cool-
ing operation?
 Is the fan speed set to “QUIET”?
When the fan speed setting is set to “QUIET”, noise reduction is prioritized and the air-conditioning
4
performance may become lower. If the volume of provided airflow is not agreeable to your prefer-
ence, set the fan speed to “LOW” or higher fan speed.
The unit operates differently  Are the batteries used in the remote controller exhausted?

setting.
Immediately stop operation and turn off the electrical breaker in following cases. Then consult authorized service personnel.
• The problem persists even if you perform these checks or diagnostics.
• The OPERATION indicator and TIMER indicator blink while the ECONOMY indicator is blinking fast.
