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, do not let water, dust, former refrigerant, or
refrigerating oil enter the refrigerating cycle during installation
work.
• 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.
To disconnect the appliance from main power supply.
• This appliance must be connected to the main power supply
by means of a switch with a contact separation of at least
0.1" (3 mm).
The installation fuse (all types can be used) must be used for
