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.

4 Evacuate the air in the connected pipes using the
vacuum pump for about 15 minutes.
• If R-410A refrigerant is charged with gas, the
composition of the charged refrigerant changes and
the characteristics of the equipment vary.
•
During the measuring operation of
refrigerant quantity added, use electronic scales. If
cylinder doesn't have siphon, upset it.

1 Before inspecting the leakage, use a torque wrench
to close the cap for the stop valve. (Comply with a
tightening torque for each size of the diameter, and
tighten the cap firmly to prevent any leakage.)
• Turn off the vacuum pump.
• 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.
