Refrigerant Piping
Piping kit used for the conventional refrigerant cannot be used.
Use copper pipe with 0.8 mm or more thickness for φ9.5mm.
Use copper pipe with 1.0 mm or more thickness for φ15.9mm.
Use copper pipe with 1.0 mm or more thickness for φ19.0mm.
Use copper pipe with 1.0 mm or more thickness for φ22.0mm.
Use copper pipe with 1.0 mm or more thickness for φ25.0mm.
Use copper pipe with 1.0 mm or more thickness for φ28.0mm.
Flare nut and flare works are also different form those of the
conventional refrigerant.take out the flare nut attached to the
main unit of the air conditioner, and use it.
Before installation
Be careful to the following items before installation.
Air purge
For air purge, use a vacuum pump.
Do not use refrigerant charged in the outdoor unit for air purge.
