Installation of R410A 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 main unit's charge port or installation tool's
connecting section differs to that of an air conditioner for the former refrigerant.
Accordingly, exclusive tools are required for the refrigerant (R410A) as shown in the following table.
• For connecting pipes, use new and clean piping materials so that water or dust does not enter.
