Installation of R410 air conditioner

This air conditioner adopts the HFC refrigerant (R410A) which does not deplete the ozone layer.
• To prevent mixing of refrigerant or refrigerating oil, the size of the charge port of the main unit or connecting
section of the installation tool differs to that of an air conditioner for the former refrigerant.
Accordingly, exclusive tools are required for the new refrigerant (R410A) as shown below.
• For connecting pipes, use new and clean piping materials so that water or dust does not enter.
■ Required Tools and Cautions on handling
Prepare the tools and equipment listed in the following table before starting the installation work.
