NEW REFRIGERANT AIR CONDITIONER INSTALLATION
THIS AIR CONDITIONER USES THE NEW HFC REFRIGERANT (R32), WHICH DOES
NOT DESTROY THE OZONE LAYER.
R32 REFRIGERANT IS APT TO BE AFFECTED BY IMPURITIES SUCH AS WATER,
OXIDIZING MEMBRANES, AND OILS BECAUSE THE PRESSURE OF R32
REFRIGERANT IS APPROX. 1.6 TIMES OF REFRIGERANT R22.

CAUTION
AS WELL AS THE ADOPTION OF THIS NEW REFRIGERANT, REFRIGERATING
MACHINE OIL HAS ALSO BEEN CHANGED. THEREFORE, DURING INSTALLATION
WORK, BE SURE THAT WATER, DUST, FORMER REFRIGERANT, OR REFRIGERATING
MACHINE OIL DOES NOT ENTER THE REFRIGERATION CYCLE OF A NEW-
REFRIGERANT AIR CONDITIONER. TO AVOID MIXING REFRIGERANT AND
REFRIGERATING MACHINE OIL, THE SIZES OF CHARGING PORT CONNECTING
SECTIONS ON THE MAIN UNIT ARE DIFFERENT FROM THOSE FOR THE
CONVENTIONAL REFRIGERANT, AND DIFFERENT SIZE TOOLS ARE ALSO REQUIRED.
FOR CONNECTING PIPES, USE NEW AND CLEAN PIPING MATERIALS WITH HIGH
PRESSURE WITHSTAND CAPABILITIES, DESIGNED FOR R32 ONLY, AND ENSURE
THAT WATER OR DUST DOES NOT ENTER. MOREOVER, DO NOT USE ANY EXISTING
PIPING AS ITS PRESSURE WITHSTAND MAY BE INSUFFICIENT AND MAY CONTAIN
IMPURITIES.
DANGER
• THE MANUFACTURER SHALL NOT ASSUME ANY LIABILITY FOR THE DAMAGE
CAUSED BY NOT OBSERVING THE DESCRIPTION OF THIS MANUAL.
• FOR USE BY QUALIFIED PERSONS ONLY.
• MEANS FOR DISCONNECTION FROM THE SUPPLY HAVING A CONTACT
SEPARATION OF AT LEAST 3 MM IN ALL POLES MUST BE INCORPORATED IN THE
FIXED WIRING.
• TURN OFF MAIN POWER SUPPLY BEFORE ATTEMPTING ANY ELECTRICAL WORK.
MAKE SURE ALL POWER SWITCHES ARE OFF. FAILURE TO DO SO MAY CAUSE
ELECTRIC SHOCK.
• CONNECT THE CONNECTING CABLES CORRECTLY. IF THE CONNECTING CABLES
ARE CONNECTED WRONGLY, ELECTRIC PARTS MAY BE DAMAGED.
• CHECK THE EARTH WIRE THAT IT IS NOT BROKEN OR DISCONNECTED BEFORE
INSTALLATION.
• DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OR 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 2 M) FROM HEAT SOURCES SUCH AS
RADIATORS, HEATERS, FURNACE, STOVES, ETC.
• WHEN MOVING THE AIR CONDITIONER FOR INSTALLING IT IN ANOTHER PLACE
AGAIN, BE VERY CAREFUL NOT TO GET THE SPECIFIED REFRIGERANT (R32)
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 RESULTANTLY
CAUSES BURST OF THE PIPE AND INJURIES ON PERSONS.
