Purging The Unit - Samsung AM050FNKDEH User & Installation Manual

Purging the unit

On delivery, the indoor unit is loaded with inert 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.
To prevent dirt or foreign objects from getting into the
pipes during installation, do NOT remove the pinch pipe
NOTE
completely until you are ready to connect the piping.
