INSTALLATION OF NEW REFRIGERANT AIR

CONDITIONER

•

The R410A refrigerant is more susceptible to impurities such as water, oxide membranes, oils, and fats.
With the adoption of the new refrigerant, the refrigerating oil has also been changed.
Be careful not to let water, dust, conventional refrigerant, and/or conventional refrigerating oil enter the refrigerating cycle of
the new refrigerant air conditioner.

•

To prevent different refrigerant or refrigerating oil from becoming mixed, the sizes of the charging port of the unit and the
installation tool connection sections are different from those of the conventional refrigerant. Accordingly, the following
exclusive tools are required for the new refrigerant R410A.

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.
