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.
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.
