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.

AIR PURGE
Evacuate the air in the connecting pipes and in
the indoor unit using vacuum pump.
Do not use the refrigerant in the outdoor unit.
For details, see the manual of vacuum pump.
<Use of vacuum pump>
(1) Connect the charge hose (A) from the manifold
valve to the charge inlet of the gas side packed
valve.
(2) Connect the charge hose (B) to the port of
vacuum pump.
(3) Open fully the low pressure side handle of the
manifold valve.
(4) Operate the vacuum pump.
(5) Close the low pressure side handle of manifold
valve after vacuumizing and stop the vacuum
pump.
Continue vacuumizing more than 15 minutes and
check the pressure gage indicates 0,1MPa
(76 cmHg).
(6) Open the stems of packed valves A and B all the
way.
(7) Securely tighten the stem cap to each of the
packed valve stems.
