Installation of Indoor Unit
1. Information for Refrigerant
1.3 R32 as an Alternative Refrigerant
The type of refrigerant applied depends on the outdoor unit cycle configuration. Ensure the refrigerant type
in the specification of the indoor unit and outdoor unit to be installed.
■ Alternative Refrigerant _ R32
• The refrigerant R32 has a lower GWP (Global Warming Potential) value, and higher efficiency than R410A.
The Ozone Depletion Potential (ODP) of R32 is 0, and Global Warming Potential(GWP) is 675.
• Refrigerant piping consists of copper/steel pipes, joints, and other fittings.All components must be selected and installed in
conformity with the standards pertaining to the Refrigeration Safety Regulation.
• Same piping as for R410A can be used.
< ! > WARNING
• This product contains fluorinated greenhouse gases (Refrigerant type : R32).
DO NOT LEAK refrigerant gases into the atmosphere.
• The refrigerant R32 is a Slightly Flammable gas. It does not leak normally. If the refrigerant leaks in the installed place and
is in contact with a flaming source, it may cause fire, or a harmful gas.
• If there is some leak, turn off any combustion devices, ventilate the installation location, and contact the dealer from which
you purchased the unit. Do not use the unit until the refrigerant leaked is repaired.
• Only use R32 as refrigerant. Other substances may cause explosions and accidents.
< ! > CAUTIONS
• The wall thickness of the piping should comply with the relevant local and national regulations for the designed pressure.
• For high-pressure refrigerant, any unapproved pipe must not be used.
• Do not heat pipes more than necessary to prevent them from softening.
