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