Step 3.3 Evacuating the air

The outdoor unit is loaded with sufficient R-410A refrigerant. Do not vent R-410A into atmosphere: it is a fluorinated greenhouse gas, covered by Kyoto Protocol, with a Global Warming Potential (GWP) = 2088. You should evacuate 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. Use a vacuum pump.

CAUTION

•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 works with the stop 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.

1Leave the system in the standby mode.

WARNING

•Do not turn on the system! This is necessary for better vacuum operation (full OPEN position of Electronic Expansion Valve).

2Connect the charging hose of the low pressure side of manifold gauge to a gas service port as seen in the picture.
