On delivery, the indoor unit is loaded with Nitrogen gas.
All this gas must therefore be purged before connecting the assembly piping.
To purge the inert gas, proceed as follows.
Unscrew the pinch pipe at the end of each refrigerant pipe.
Result: All inert gas escapes from the indoor unit.
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.

E-9
Connecting the Refrigerant Pipe
ENGLISH
There are two refrigerant pipes of differing diameters:

A smaller one for the liquid refrigerant

A larger one for the gas refrigerant

The inside of copper pipe must be clean & has no dust.
