Relocation
• Only a qualified installer(*1) or qualified service person(*1) is allowed
to relocate the air conditioner. It is dangerous for the air conditioner
to be relocated by an unqualified individual since a fire, electric
shocks, injury, water leakage, noise and / or vibration may result.
• When carrying out the pump-down work shut down the compressor
before disconnecting the refrigerant pipe. Disconnecting the
refrigerant pipe with the service valve left open and the compressor
still operating will cause air or other gas to be sucked in, raising the
pressure inside the refrigeration cycle to an abnormally high level,
and possibly resulting in rupture, injury or other trouble.

CAUTION
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.
(*1) Refer to the "Definition of Qualified Installer or Qualified Service Person."
