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.
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.
