Relocation
• Only a qualifi ed installer(*1) or qualifi ed service person(*1) is
allowed to relocate the air conditioner. It is dangerous for the air
conditioner to be relocated by an unqualifi ed individual since a
fi re, 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, etc. to
be sucked in, raising the pressure inside the refrigeration cycle
to an abnormally high level, and possibly resulting in reputing,
injury, etc.
WARNING
• After installation work, make sure below before operation.
- Connection pipes are connected properly and no leakage.
- Packed valves are fully open.
Running compressor without open packed valves may cause
abnormal high pressure and parts failure.
Leakage at connection piping may suck air and make further high
pressure cause burst and injure.
CAUTION
This air conditioner adopts the HFC refrigerant (R32) which does
not destroy the ozone layer.
• R32 refrigerant has a high working pressure and is apt to be
affected by impurities such as water, oxidizing membrane, and
oils. Therefore, during installation work, be careful that water,
dust, previous refrigerant, refrigerating machine oil, or other
substances do not enter the R32 refrigeration cycle.
• Special tools for R32 or R410A refrigerant are required for
installation.
• For connecting pipes, use new and clean piping materials, and
make sure that water and/or dust does not enter.

Cautions for outdoor unit installation space
• In the event that the outdoor unit is installed in a small space
and refrigerant leaks, accumulation of highly concentrated
refrigerant may cause a fi re hazard. Therefore, be sure to follow
the installation space instructions in the Installation Manual, and
provide open space on at least one of the four outdoor unit sides.
• In particular, when both the discharge and intake sides face walls
and obstacles are also placed on both sides of the outdoor unit,
take steps to provide space wide enough for a person to pass
(600 mm or more) on one side to prevent leaked refrigerant from
accumulating.
Obstacle
600 mm or more
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 3 mm.
Do not wash air conditioners with pressure washers.
• Electric leaks may cause electric shocks or fi res.
(*1) Refer to the "Definition of Qualified Installer or Qualified
Service Person."
