Purging the Unit
On delivery, the indoor unit is loaded with an inert nitrogen gas.
All this gas must therefore be purged before connecting the assembly
piping. To purge the inert gas, proceed as follows.
Unscrew the caps at the end of each 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 caps completely until
you are ready to connect the piping.
