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.
• Sometimes the indoor unit may not get to the set fan speed such as LOW and 
QUIET under cool operation at very low outdoor temperatures due to the 
indoor unit being protected from ice or frost when combined with the outdoor 
unit for Low Ambient Cooling models.
• In the event of power failure, the unit will stop. When the power is resumed, 
the unit will restart automatically within 15 minutes by the remote controller.
Clicking sound is heard from
the air conditioner• In cooling operation, any plastic parts may 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.

USING THE 1-HOUR OFF TIMER
TIPS FOR ENERGY SAVING
1. 1-Hour OFF Timer This function causes the unit to operate for one hour and then stop, 
regardless of whether the unit is on or off when this button is pressed.
The   indicator in the display indicates that this function is operating.
Setting procedure:
Regardless of whether the unit is operating or stopped, press the 1 HR. TIMER 
button.
 appears in the display.
Cancellation procedure:
Press the ON/OFF operation button to turn the unit off, wait for the unit to stop 
operating, and then press the ON/OFF operation button again. 
The 1-Hour Timer function is now cancelled and the unit operates normally.
• If, while the 1-Hour Timer function is operating, the 1HR. TIMER 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 TimerThe 1-Hour OFF Timer setting is given priority over the DAILY ON/OFF REPEAT 
setting.
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.
NOTE

ADJUSTING THE AIRFLOW DIRECTION
1. HorizontalThe 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. VerticalThe 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.
• 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.
CAUTION
A. Sweep function 
The flap starts moving up and down to 
deliver air over the sweep range.
C. Auto flap function 
The flap is set to the recommended 
position.B. Setting the airflow manually
Referring to the above illustration, use the 
FLAP button to set the airflow direction 
within the range used during the cooling or 
dehumidifying operation.
