Refrigerant Piping

•Piping kit used for the conventional refrigerant cannot be used.

•Use copper pipe with 0.8 mm or more thickness for Ø6.4, Ø9.5, Ø12.7.

Use copper pipe with 1.0 mm or more thickness for Ø15.9.

•Flare nut and flare works are also different from those of the conventional refrigerant. Take out the flare nut attached to the main unit of the air conditioner, and use it.
