CAUTION
New Refrigerant Air Conditioner Installation
• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY OZONE
LAYER.
R410A refrigerant is apt to be affected by impurities such as water, oxidizing membrane, and oils because the working pressure of
R410A refrigerant is approx. 1.6 times as that of refrigerant R22. Accompanied with the adoption of the new refrigerant, the
refrigeration machine oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant,
or refrigeration machine oil does not enter the new type refrigerant R410A air conditioner circuit.
To prevent mixing of refrigerant or refrigerating machine oil, the sizes of connecting sections of charging port on main unit and
installation tools are different from those of the conventional refrigerant units. Accordingly, special tools are required for the new
refrigerant (R410A) units as shown on page 4. For connecting pipes, use new and clean piping materials with high pressure
fittings made for R410A only, so that water and/or dust does not enter. Moreover, do not use the existing piping because there are
some problems with pressure fittings and possible impurities in existing piping.
CAUTION
TO DISCONNECT THE APPLIANCE FROM THE MAIN POWER SUPPLY
Disconnection from the supply mains:
The means for disconnection must be incorporated in the fixed wiring in accordance with the wiring rules.
