7-2-1. Louver Control
(1) Vertical air flow louvers
Positions of vertical air flow louvers are automatically
controlled according to the operation status (COOL,
AUTO, DRY, FAN ONLY). Besides, positions of
vertical air flow louvers can be arbitrarily set by
pushing the [SET] button. The louver position which
has been set by the [SET] button is stored in
microcomputer, and the louver is automatically set at
the stored position in the next operation.
(2) Swing
If the [AUTO] button is pushed during running opera-
tion, vertical air flow louvers start swinging. When
the [AUTO] button is pushed again, swinging stops.
7-3. DRY Operation

7-7. Auto Restart Function
This unit is equipped with an Automatic restarting
function which allows the unit to restart and resume
the set operating conditions in the event of a supply
power shutdown without the use of the hand control.
The operation will resume without warning three
minutes after the power is restored.
INFORMATION
The AUTO RESTART FUNCTION is set not to work
on shipment from the factory, and so it is necessary
to set it to function as required.
7-7-1. How to Set the Auto Restart
To set the Auto Restart function, proceed as follows:
Access the TEMPORARY button located in the lower
right hand corner beneath the hinged front panel of
the indoor unit (please refer to section on PARTS
NAME). The power supply to the unit must be on -
the function will not be set if the power is off.
To enable the Auto Restart function, push the TEM-
PORARY button continuously for three seconds.
The unit will acknowledge the setting and beep three
times. The system will now restart automatically.
The above Auto Restart settings can be carried out:
During subsequent operation, the orange light goes on.
The Auto Restart function will not accept an instruction if timer operation with the remote control is selected.
During louver swing (AUTO) operation, after restarting by the Auto Restart function, the louver swing stops.

7-7-3. In Case of Power Failure during the Timer Operation
(1) If ON-TIMER operation is reserved with setting of Auto Restart operation, it is cancelled with power failure.
(The OPERATION lamp on the main unit goes on and off to inform of power failure.) In that case, try to
reserve ON-TIMER operation once again.
(2) If OFF-TIMER operation is reserved without setting of Auto Restart operation, the reservation is cancelled
with power failure. (The OPERATION lamp on the main unit goes on and off to inform of power failure.) In that
case, try to reserve OFF-TIMER operation. When Auto Restart operation is set, OFF-TIMER reservation is
also cancelled with power failure.

8. INSTALLATION PROCEDURE
8-1. Safety Cautions
For general public use
Power supply cord of parts of appliance for Outdoor use shall be more than polychloroprene sheathed flexible cord
(design H05 RN-F), or cord designation 245 IEC 57.
CAUTION
TO DISCONNECT THE APPLIANCE FROM THE MAINS SUPPLY.
This appliance must be connected to the mains by means of a circuit breaker or a switch with a contact separation
of at least 3 mm.
If this is not possible, a power supply plug with earth must be used. This plug must be easily accessible after
installation. The plug must be disconnected from the power supply socket in order to disconnect the appliance
completely from the mains.
DANGER
ENGAGE DEALER OR SPECIALIST FOR INSTALLATION.
` FOR ELECTRICAL WORKS THE WIRING AND CABLES MUST BE PERFORMED IN COMPLIANCE WITH
NATIONAL WIRING STANDARD OR REGULATION.
IF INCORRECT AND INCOMPLETE WIRING IS CARRIED OUT, IT WILL CAUSE AN ELECTRICAL FIRE OR
ELECTRICAL SHOCK.
` USE THE SPECIFIED CABLE (1,5 to 2,0mm²) AND CONNECT TIGHTLY FOR INDOOR/OUTDOOR
CONNECTION. CONNECT TIGHTLY AND CLAMP THE CABLE SO THAT EXTERNAL FORCE WILL BE
ACTED ON THE TERMINAL.
` WIRE ROUTING MUST BE PROPERLY ARRANGED SO THAT CONTROL BOARD COVER IS FIXED
PROPERLY.
` DO NOT DAMAGE OR SCRATCH THE CONDUCTIVE CORE AND INNER INSULATOR OF THE CABLES.
` DO NOT DEFORM OR SMASH ON THE SURFACE OF THE CABLES. DO NOT PRESS OR FIX THE CORD
AND CABLES FIRMLY WITH STAPLES, etc.
` DO NOT USE THE EXTENSION CABLE FOR POWER SUPPLY CORD OR INTER-CONNECTING CABLE.
NEVER EXECUTE THE CONNECTION OF WIRING WITH OTHER METHOD THAN THE APPROVED ONE.
OTHERWISE, OVERHEAT, SMOKE OR FIRE MAY BE GENERATED BY CONTACT ERROR.
` TURN OFF MAIN POWER SUPPLY AND BREAKER BEFORE ATTEMPTING ANY ELECTRICAL WORK.
MAKE SURE ALL POWER SWITCHES AND BREAKER TURN OFF. FAILURE TO DO SO MAY CAUSE
ELECTRIC SHOCK.
` CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS CONNECTED BY
WRONG WAY, ELECTRIC PARTS MAY BE DAMAGED.
` GROUNDING WIRE WORKS MUST BE CONSTRUCTED IN COMPLIANCE WITH INSTALLATION MANUAL.
` DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS VAPORS.
FAILURE TO FOLLOW THIS INSTRUCTION CAN RESULT IN FIRE OR EXPLOSION.
` TO PREVENT OVERHEATING THE INDOOR UNIT AND CAUSING A FIRE HAZARD. PLACE THE UNIT WELL
AWAY (MORE THAN 2M.) FROM HEAT SOURCE SUCH AS RADIATORS, HEAT REGISTORS. FURNACE,
STOVES, etc.
` IF A REFRIGERATION GAS LEAKS DURING INSTALLATION, BE SURE TO PERFORM VENTLATION.
IF THE REFRIGERANT GAS COMES INTO CONTACT WITH FIRE, A POISONOUS GAS MAY OCCUR.
WHEN INSTALLING AN AIR CONDITIONER, DO NOT ALLOW AIR OR MOISTURE TO REMAIN IN THE
REFRIGERATION CYCLE. OTHERWISE, PRESSURE IN THE REFRIGERATION CYCLE MAY BECOME
ABNORMALLY HIGH SO THAT A RUPTURE OR PERSONAL INJURY MAY BE CAUSED.
` BE SURE TO USE THE CORD-CLAMPS AND THE ELECTRIC PARTS COVER TO THE SPECIFIED
POSITION WITH ATTACHED TO THE PRODUCT. MOUNT THE ELECTRIC PARTS COVER FOR CABLES OF
CONNECTING SECTION FIRMLY WITH THE SCREWS.
