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.
• While 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.
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.
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 the power
supply line of this air conditioner.
Install the indoor unit at least 8'2" (2.5 m) above the floor level since otherwise
the users may injure themselves or receive electric shocks if they poke
their fingers or other objects into the indoor unit while the air conditioner
is running.
(*1) Refer to the "Definition of Qualified Installer or Qualified Service Person."
