OPERATION WITH THE REMOTE CONTROLLER
1. Automatic OperationThe air conditioner calculates the difference between the thermostat setting and 
room temperature, and automatically determines the mode to operate under 
cooling or heating. Then, the air conditioner continuously operates under the 
mode selected at initial operation.
Check that the circuit breaker on the power panel is turned on.
Once   mode is selected and the unit is preset by following the steps below, you 
can have the air conditioner automatically bring the room to the desired 
temperature simply by pressing the ON/OFF operation button.
STEP 1Press the MODE selector button to  .
STEP 2Press the ON/OFF operation button.
To stop the air conditioner, press the ON/OFF operation button again.
• To change the temperature setting; press the temperature setting buttons and 
change the setting to the desired temperature.

• Choose the best position in the room for the remote controller, which also acts 
as the sensor for room comfort and transmits the operating instructions. Once 
you’ve found this best position, always keep the remote controller there.
• This appliance has a built-in 5-minute time delay circuit to ensure reliable 
operation. When the operation button is pressed, the compressor will start 
running within three minutes. In the event of power failure, the unit will stop. 
3.  Adjusting the Fan Speed

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• 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 operating.
• 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 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.

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.

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.
• 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.
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 heating, 
cooling, or dehumidifying operation.
