same time.
• Pressing the MODE selector button cancels HIGH POWER mode. 
• When set to High fan speed during heating operation, the fan runs 
at High fan speed even though the   mark is displayed.
• Depending on the operating conditions, the fan speed may be 
increased by a small amount only.
8.  UNOCCUPIED Mode
Unoccupied mode is used to prevent the room temperature from 
decreasing too much (or increasing too much) when no one is in the 
room, and operates automatically to save energy.
Press the UNOCCUPIED button.
The   mark appears in the display. 
To release the unoccupied function, press the UNOCCUPIED button 
again.
Unoccupied Indication
Even if Unoccupied Mode is ON, it will be disabled if the air

• Unoccupied Function can be set and released through all 
operational modes, regardless of whether the air conditioner is 
operating or not. 
• If the Unoccupied Function is ON and the remote controller is used 
to turn the air conditioner OFF (including OFF TIMER), the air 
conditioner will turn off, but depending on the room temperature, 
Heating or Cooling Operation will automatically begin.
• When the Unoccupied Function is in operation and the ON/OFF 
operation button is pressed, operation will restart based on the 
settings input before the air conditioner was turned off.

A. In Heating Mode: ( )
B. In Cooling Mode: ( )
• Unoccupied Mode triggers Heating or Cooling Operation in 
response to the room temperature, but when this happens, the 
remote controller will continue to display the Operation mode set by 
the user.
• If the room temperature rapidly changes, the room temperature 
may get over the upper or lower limit when the unoccupied function 
is activated.
• The remote controller should be used in the location specified in 
“REMOTE CONTROLLER INSTALLATION POSITION” on page 8.
• The air conditioner’s stop order (stated in (2) / above) is valid only 
when the unoccupied function is operated.
SPECIAL REMARKS
How it works?
• Once the room temperature reaches the level that was set, the 
unit’s operation frequency is changed automatically.
• During DRY operation, the fan speed automatically runs at lower 
speed for providing a comfortable breeze.
• ‘‘DRY’’ operation is not possible if the indoor temperature is 59 °F 
or less.
Heating performance
• When High power operation  , Fan speed Automatic operation 
, HIGH   or MEDIUM   has been changed to Fan speed 
LOW  , Quiet operation   or Night Setback  , the fan 
speed may not be reduced to the desired setting immediately but 
rather it may be reduced slowly in steps due to the operating status 
of the air conditioner. (A maximum of 5 minutes are required for the 
change to be completed.)
• Because this air conditioner heats a room by drawing in the heat of 
the outside air (heat pump system), the heating efficiency will fall 
off when the outdoor temperature is very low. If sufficient heat 
cannot be obtained with this air conditioner, use another heating 
appliance together with it.
Defrosting
• When the outdoor temperature is low, frost or ice may form on the 
heat exchanger coil, reducing heating performance. When this 
happens, a microcomputer defrosting system operates. At the 
same time, the fan on the indoor unit stops and the OPERATION 
lamp lights red and orange alternately until defrosting is completed. 
Heating operation restarts after several minutes. (This interval will 
vary slightly depending upon the outdoor temperature and the way 
in which frost forms.)
Cold draft prevention
• For several minutes after the start of heating operation, the indoor 
fan runs at a lower speed until the indoor heat exchanger coil has 
warmed up sufficiently. However, the fan may remain stopped when 
the room temperature is low. This is because the COLD DRAFT 
PREVENTION SYSTEM is in operation.
• Sometimes the indoor unit may not get to the set fan speed such as 
LOW under cool operation at very low outdoor temperatures due to 
the indoor unit being protected from ice or frost.
• In the event of power failure, the unit will stop. When the power is 
resumed, the unit will restart automatically in approximately 
5 minutes by the remote controller.
If the remote controller is on and left in a location where the unit 
can receive a signal, then the unit will automatically restart in 
approximately 5 minutes of power being restored.
Clicking sound is heard from the air conditioner
• In heating or cooling operation, any plastic parts may expand or 
shrink due to a sudden temperature change. In this event, a 
clicking sound may occur. This is normal, and the sound will soon 
disappear.
• The remote controller sends the setting condition to the air 
conditioner regularly at five minute intervals.

button is pressed once to cancel the function and then again, the 
unit continues to operate for one hour from that point in time and 
then stops.
• It is not possible to use the OFF Timer and 1-Hour OFF Timer 
together. Whichever function is set last takes precedence. If the 1 
HR. TIMER button is pressed while the TIMER OFF function 
operates, the OFF Timer is cancelled and the unit will stop 
operating one hour later.
2. Operation together with the daily ON/OFF 
repeat timer
The 1-Hour OFF Timer setting is given priority over the DAILY ON/
OFF REPEAT setting.
TIPS FOR ENERGY SAVING
Avoid
• Do not block neither the air intake nor the air outlet. It may 
cause less performance, and may leads to malfunctions.
• Do not let direct sunlight into the room. Use sunshades, blinds or 
curtains. If the walls and ceiling of the room are warmed by the 
sun, it will take longer to cool the room.
Do
• Always try to keep the air filter clean. (Refer to “CARE AND 
CLEANING”.) A clogged filter will impair the performance of the 
unit.
• To prevent conditioned air from escaping, keep windows, doors and 
any other openings closed.

ADJUSTING THE AIRFLOW 
DIRECTION
1. Horizontal
The horizontal airflow can be adjusted by moving the vertical vanes 
with your hands to the left or right.
When the humidity is high, the vertical vanes should be in the 
front position during the cooling or dehumidifying operation. If 
the vertical vanes are positioned all of the way to the right or 
left, condensation may begin to form around the air vent and 
drip down.
2. Vertical
The vertical airflow can be adjusted by moving the flap with the 
remote controller. Do not move the flap with your hands. Confirm that 
the remote controller has been turned on. Use the FLAP button to 
set either the sweep function or one of the six airflow direction 
settings.
• The flap automatically closes when the unit is off.
• During the heating operation, the fan speed will be very low and the 
flap will be in the horizontal position (position  ) until the air being 
blown out of the unit begins to warm. Once the air warms up, the 
flap position and fan speed change to the settings specified with 
the remote controller.• Use the FLAP button on the remote controller to adjust the 
position of the flap. If you move the flap by hand, the flap 
position according to the remote controller and the actual 
flap position may no longer match. If this should happen, 
shut off the unit, wait for the flap to close, and then turn on 
the unit again; the flap position will now be normal again.
• Do not have the flap pointed down during cooling operation. 
Condensation may begin to form around the air vent and drip 
down.
