Step 5 Purging inert gas from the
indoor unit
The indoor unit comes with nitrogen gas (inert gas)
charged at the factory. Therefore, all inert gas must be
purged before connecting the refrigerant pipes.
Unscrew the pinch pipe at the end of each refrigerant pipe.

NOTE
• To prevent dirt or foreign objects from getting into the
pipes during installation, do not remove the pinch pipe
completely until you are ready to connect the piping.
Step 6 Cutting and flaring the pipes
1
Make sure that you have the required tools available:
pipe cutter, reamer, flaring tool, and pipe holder.
2
If you wish to shorten the pipes, cut them with a pipe
cutter, ensuring that the cut edge remains at a 90° angle
to the side of the pipe. Refer to the illustrations below
for examples of edges cut correctly and incorrectly.
