be sucked in, raising the pressure inside the refrigeration cycle
to an abnormally high level, and possibly resulting in reputing,
injury, etc.
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.
