Purging the connected pipes
The outdoor unit is loaded with sufficient R410A refrigerant. Do not vent R410A into atmosphere: it is a fluorinated
greenhouse gas, covered by Kyoto Protocol, with a Global Warming Potential (GWP) = 1975.
You should purge the air in the indoor unit and in the pipe. If air remains in the refrigerant pipes, it affects the compressor.
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.
• W
hen installing, make sure there is no leakage. When recovering the refrigerant, ground the compressor first
before removing the connection pipe. If the refrigerant pipe is not properly connected and the compressor works
with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle
abnormally high. It may cause explosion and injury.
1. Connect each assembly pipe to the appropriate valve on the outdoor unit and
tighten the flare nut.
2. Tighten the flare nut first with your hands, and then with a torque wrench,
applying the following torque:
• Excessive torque can be cause of gas leakage.
• M
ake the electrical connection and leave the system into “stand by
mode”. Do not turn on the system!
