PREPARING THE INSTALLATION
Purging the Unit
On delivery, the indoor unit is loaded with an inert 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.
