From factory the unit is supplied and set with a pre-charge of nitrogen
gas (insert gas).Therefore, all insert gas must be purged before
connecting the assembly piping.
Make sure all the nitrogen gas is purged out before installing the unit.
If not, do not install the unit because leftover nitrogen could cause
internal leakage.
Unscrew the pinch pipe at the end of each refrigerant pipe.
Result:
All inert gas escapes from the indoor unit.
