USING THE 1-HOUR OFF  
TIMER  
ADJUSTING THE AIRFLOW  
DIRECTION  
The vertical airflow can be adjusted by moving the flap with the  
remote control unit. Do not move the flap with your hands. Confirm  
that the remote control unit has been turned on. Use the FLAP  
button to set either the sweep function or one of the six airflow  
direction settings.  
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.  
A. Sweep function  
The flap starts moving  
up and down to deliver  
air over the sweep  
range.  
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.  
B. Setting the airflow manually  
appears in the display.  
SWEEP  
Referring to the above  
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.

operation.  
NOTE  
• 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.  
NOTE  
• 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 control unit.  
CAUTION  
2. Operation together with the daily ON/OFF  
repeat timer  
• Use the FLAP button on the remote control unit to adjust the  
position of the flap. If you move the flap by hand, the flap  
position according to the remote control unit 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.  
The 1-Hour OFF Timer setting is given priority over the DAILY ON/  
OFF REPEAT setting.

the noise filter is contained within the space of the component box. (Fig. 5b)  
(9) Pass the wire tube through the clamping strap, and temporarily fasten in place  
with the screw. Next, use a clamp and bind the wires together immediately above  
the clamping strap, and fasten in place with the screw in order to prevent pulling  
on the wire harness. (Fig. 6a)  
• Install the wire tube so that the wires cannot be damaged by the edge of the  
metal plate. (Fig. 6a)  
• When re-installing the grille, confirm that there is no slack in the wire harness  
wires.  
(10) Install the top cover on the component box. (Fig. 8)  
(11) Route the wire harness out through the small cut-out located at the bottom right  
side of the indoor unit frame. (Fig. 7a)
