This air conditioner adopts the HFC refrigerant (R410A)
which does not destroy ozone layer.
• The characteristics of R410A refrigerant are; easy to absorb
water, oxidizing membrane or oil, and its pressure is approx. 1.6
times higher than that of refrigerant R22. Accompanied with the
R410A refrigerant, refrigerating oil has also been changed.
Therefore, during installation work, be sure that water, dust,
former refrigerant, or refrigerating oil does not enter the
refrigerating cycle.
• To prevent charging an incorrect refrigerant and refrigerating
oil, the sizes of connecting sections of charging port of the
main unit and installation tools are changed from those for the
conventional refrigerant.
• Accordingly the exclusive tools are required for the R410A
refrigerant.
• For connecting pipes, use new and clean piping designed for
R410A, and please care so that water or dust does not enter.
