  • Page 24: Connecting Up And Removing Air In The Circuit

    Connecting up and removing air in the circuit • When 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 CAUTION works with the service valve open, the pipe inhales the air and it makes the pressure inside of the refrigerant cycle abnormally high.
  • Page 25 5. Purge the air from the system using vacuum pump for about 10 minutes. Close the valve of the low pressure side of manifold gauge clockwise. Make sure that pressure gauge shows -0.1MPa(-76cmHg) after about 10 minutes. This procedure is very important to avoid a gas leak. B(liquid) A(gas) Turn off the vacuum pump.
