7. OPERATION DESCRIPTIONS
7-1. FAN ONLY Operation
(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.
Fig. 7-2-2
(3) 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 the START/STOP button.

(2) Relays RY01 and RY02 are turned on to energize
the outdoor unit, and a cool operation is carried
out.
1) When the FAN is set to AUTO, the indoor fan
motor operates as shown in Fig 7-2-2.
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.

7-2-1. Louver Control
(1) By pushing the SET button of the remote control
during the operation, the louver can be set to the
desired position.
And the louver position is stored in the microcom-
puter, the louvers will be set to the position au-
tomatically at the next operation.
(2) When the AUTO button is pushed, the louver ver-
tically swings within range of 25deg.
7-3. DRY Operation
(MODE of the remote control : DRY)
(1) Compressor, outdoor fan and operation display
are controlled as shown in Fig. 7-3-1.
Fig. 7-3-2
Fig. 7-3-1
• The microprocessor turns the compressor on
and off at regular intervals (4 to 6 minutes on
and/or off). During the compressor off, the
indoor fan will operate in the super low position.
• The indoor fan will operate in the AUTO
position.
(2) The pattern of operation depending on the relation
between room temperature and set temperature

7-4. AUTO Operation
(MODE of the remote control : AUTO)
(1) One of the 2 modes, Cooling or Dry is selected
according to room temperature at which operation
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, the set
temperature is fixed at 24°C and controlled in accor-
dance with the chart shown in Fig. 7-4-1.

7-5. ECONO. Mode
When the ECONO. button is pushed, during COOL
and AUTO operation, the OPERATION display is
turned off and the ECONO. display is lit and the indoor
unit operates quietly and mildly with controlling airflow.

7-7. Auto Restart Function
This unit is equipped with an Automatic restarting
facility which allows the unit to restart and resume the
set operating conditions in the event of a power supply
shutdown without the use of the hand control.
The operation will resume without warning three
minutes after the power is restored.
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 function will not be set if the power is off.
To enable the Auto Restart function, press the
TEMPORARY button continuously for three seconds.
The unit will acknowledge the setting and beep three
times. The system will now restart automatically.

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
` FOR USE BY QUALIFIED PERSONS ONLY.
` 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
ELECTRICAL SHOCK.
` CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS CONNECTED BY
WRONG WAY, ELECTRIC PARTS MAY BE DAMAGED.
` CHECK THE EARTH WIRE IS NOT BROKEN OR DISCONNECTED BEFORE INSTALLATION.
` DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OF 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 SOURCES SUCH AS RADIATORS, HEAT RESISTORS,
FURNACE, STOVES, ETC..
` WHEN MOVING THE AIR-CONDITIONER FOR INSTALLING IT IN ANOTHER PLACE AGAIN, BE VERY
CAREFUL NOT TO GET THE SPECIFIED REFRIGERANT (R-22) WITH ANY OTHER GASEOUS BODY
INTO THE REFRIGERATION CYCLE. IF AIR OR ANY OTHER GAS IS MIXED IN THE REFRIGERANT,
THE GAS PRESSURE IN THE REFRIGERATION CYCLE BECOMES ABNORMALLY HIGH AND IT
RESULTINGLY CAUSES BURST OF THE PIPE AND INJURIES ON PERSONS.
` IN THE EVENT THAT THE REFRIGERANT GAS LEAKS OUT OF THE PIPE DURING THE INSTALLATION
WORK, IMMEDIATELY LET FRESH AIR INTO THE ROOM. IF THE REFRIGERANT GAS IS HEATED BY
FIRE OR SOMETHING ELSE, IT CAUSES GENERATION OF POISONOUS GAS.
WARNING
• Never modify this unit by removing any of the safety guards or by by-passing any of the safety interlock
switches.
• Do not install in a place which cannot bear the weight of the unit.
Personal injury and property damage can result if the unit falls.
