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.
Never recover the refrigerant into the outdoor unit. Be sure to use a refrigerant recovery machine to recover the refrigerant when
moving or repairing. It is impossible to recover the refrigerant into the outdoor unit. Refrigerant recovery into the outdoor unit may
result in serious accidents such as explosion of the unit, injury or other accidents.
(*1) Refer to the "Definition of Qualified Installer or Qualified Service Person."
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, 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.
Disconnection of the appliance from mains power supply.
This appliance must be connected to the main power supply by means of a switch with a contact separation of at least 3 mm.
The installation fuse (all type can be used) must be used for the power supply line of this conditioner.
