New Refrigerant Air Conditioner Installation
• THIS AIR CONDITIONER ADOPTS THE NEW 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 new 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 new refrigerant
(R410A).
For connecting pipes, use new and clean piping designed for
R410A, and please care so that water or dust does not enter.
Moreover, do not use the existing piping because there are
problems with pressure-resistance force and impurity in it.
