• The refrigerant R290 has a lower GWP(Global Warming Potential)value than R32.
The Ozone Depletion Potential (ODP) of R290 is 0, and Global Warming Potential(GWP) is 3.
• 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 R32 can be used.
