temperature setting in COOL, DRY, or HEAT mode.  
• 20 minutes have passed after nishing the POWERFUL operation  
mode setting.  
Then set the ON timer by the air conditioner stops opera-  
tion controlled with the OFF timer earlier set.  
The timer that is set later starts counting down after the counting

Automatic defrosting operation  
When outdoor temperature is very low with high humidity, frost  
may form on the outdoor unit during the heating operation, and  
it could reduce the operating performance of the product.  
For frost protection, a microcomputer-controlled automatic  
defrost function is equipped in this air conditioner.  
If frost forms, the air conditioner will temporarily stop, and  
defrost circuit will operate briey (maximum of 15 minutes.)

Note for TIMER settings:  
Any interruption of the power supply, such as a blackout or cutting off  
of a circuit breaker, makes the set internal clock go wrong. In such a  
case, the TIMER indicator on the indoor unit blinks, and you need to  
readjust the setting.  
12 °F/°C button  
If frost forms on the outdoor unit after the heating operation, the  
outdoor unit will stop automatically after it operates for a few  
minutes. Then the automatic defrosting operation starts.  
• Used for changing the temperature unit. (Initial setting: °F )  
• When you press this button, the displayed temperature unit switches  
to “°C”, and returns to “°F” when you press it again.  
• When you press this button, press it gently by using the tip of a  
ballpoint pen or other small object in correct direction as shown in  
this gure.  
Auto-restart function  
In event of power interruption such as a blackout, the air  
conditioner stops once. But it restarts automatically and  
performs previous operation when the power supply is resumed.  
If any power interruption occurs after the timer is set, counting  
down of the timer will be reset.  
After the power supply is resumed, the TIMER indicator on the  
indoor unit blinks to notify you that there has been a timer fault.  
In such a case, reset the timer for your opportune time.  
13 ECONOMY button  
Starts or stops ECONOMY operation that saves more electricity  
consumption than the other operations with a conservative adjustment  
of the room temperature.  
When you press the button, the ECONOMY indicator on the indoor  
unit turns on.  
• In COOL mode, the room temperature will be adjusted at a few  
degree higher than the dened temperature.  
Malfunctions caused by other electrical devices:  
Use of other electrical appliances such as an electric shaver or  
nearby use of a wireless radio transmitter may cause the malfunction  
of the air conditioner.  
If you encounter such a malfunction, turn off the circuit breaker once.  
Then turn it on again, and resume operation by using the remote  
controller.  
In HEAT mode, the room temperature will be adjusted at a few  
degree lower than the dened temperature.  
• Especially in COOL mode, you can have improved dehumidication  
without signicantly lowering the room temperature.  
Notes:  
• In COOL or HEAT mode, the maximum output of this operation is  
approximately 70 % of usual air conditioning operation.  
• This operation cannot be performed during temperature monitoring  
by AUTO mode.

Troubleshooting  
WARNING  
In the event of a malfunction such as burning smell, immediately stop operation of the air conditioner, and disconnect all the power supply  
by turning off the electrical breaker or disconnecting the power plug. Then consult authorized service personnel.  
As long as the unit is connected to the power supply, it is not insulated from the power supply even if the unit is turned off.  
Following symptoms do not indicate the product malfunction, but they are normal functions or characteristics of this product.  
Symptom  
Cause  
See page  
Operation is delayed after  
restart.  
To prevent blowout of the fuse, the compressor will not operate during the protection circuit is working  
for about 3 minutes after sudden OFFON operation of the power supply.  
Noise is heard.  
• During the operation or immediately after stopping the air conditioner, refrigerant owing 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  
heard.

Smell coming from the unit.  
Absorbed room smell generated from interior textile, furniture, or cigarette smoke into the air condi-  
tioner may be emitted.  
Mist or steam is emitted from  
the unit.  
In COOL or DRY mode, a thin mist generated by condensation formed with sudden cooling process  
may be emitted.  
During heating operation, the fan built-in the outdoor unit may stops and rising steam generated by  
the automatic defrosting operation may be seen.  
Airow 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  
defrosting operation while the OPERATION indicator is ashing.

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 airow is reduced.  
When monitoring operation is performed in AUTO mode, the fan rotates at very low speed.  
Outdoor unit emits water.  
During heating operation, the outdoor unit may emit water generated by the automatic defrosting  
operation.
