Installation of R32 refrigerant air conditioner

CAUTION
R32 refrigerant air conditioner installation
• This air conditioner adopts the HFC refrigerant (R32) which does not destroy ozone layer.
Therefore, during installation work, make sure that water, dust, former refrigerant, or refrigerant oil does not enter
the R32 refrigerant air conditioner cycle. To prevent mixing of refrigerant or refrigerant oil, the sizes of connecting
sections of charge port on the main unit and installation tools are different from those of the conventional
refrigerant units.
Accordingly, special tools are required for the R32 or R410A refrigerant units. For connecting pipes, use new and
clean piping materials with high pressure fittings made for the R32 or R410A only, so that water and/or dust does
not enter.
Required Tools/Equipment and Precautions for use
Prepare the tools and equipment listed in the following table before starting the installation work.
Newly prepared tools and equipment must be used exclusively.
