greenhouse gas, covered by Kyoto Protocol, with a Global Warming Potential (GWP) = 1975.
It may cause reduction of cooling capacity and malfunction. Refrigerant for air purging is not charged in the outdoor unit.
Use Vacuum Pump as seen in the picture.
1. Connect each assembly pipe to the appropriate valve on the outdoor unit and
2.
applying the following torque:
• When installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor
before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works

abnormally high. It may cause explosion and injury.
