7. OPERATION DESCRIPTIONS
7-1. FAN ONLY Operation
(The Remote Control MODE Button
is Set to the FAN ONLY Operation)
Once the setting is made, the operation mode is
memorized in the microcomputer so that the same
operation can be effected thereafter simply by
pushing [START/STOP] button.
(MODE of the remote control : FAN ONLY)
(1) During this mode, the relay RY01 is always
turned off so that only the indoor fan is operated.
RY02 is always turnd on. FAN-ONLY display is lit.
1) When the FAN is set to AUTO, the indoor fan
motor operates as shown in Fig 7-1-1.
2) When the FAN is set to LOW, MED. or HIGH,
the indoor fan motor operates with a constant
in volume as listed in Table 7-1-1.
7-2. COOL Operation
(MODE of the remote control : COOL)
(1) Compressor, outdoor fan and operation display
are controlled as shown in Fig. 7-2-1.

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
(MODE of the remote control : DRY)

(MODE of the remote control : AUTO)
(1) One of the 2 modes, Cooling or Dry is selected
according to room temperature at which opera-
tion is to start, as shown in Fig. 7-4-1. The Fan
mode will continue until room temperature
reaches a level at which another mode is
selected.
7-4-1. Temporary Auto
When the TEMPORARY button is pushed (1 sec),
the set temperature is fixed at 24°C and controlled in
accordance with the chart shown in Fig. 7-4-1.

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

(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

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.
